                        THE STATE OF NEW HAMPSHIRE

                                         v.

                               ABRAHAM DEPAULA

                           Argued: January 17, 2017
                         Opinion Issued: June 22, 2017

      Joseph A. Foster, attorney general (Sean R. Locke, assistant attorney
general, on the brief and orally), for the State.


      Christopher M. Johnson, chief appellate defender, of Concord, on the
brief and orally, for the defendant.

       LYNN, J. The defendant, Abraham DePaula, appeals his convictions,
following a jury trial in Superior Court (Delker, J.), on one count of burglary,
five counts of theft by unauthorized taking, and two counts of conspiracy to
commit theft by unauthorized taking. See RSA 635:1 (2007); RSA 629:3
(2016); RSA 637:3 (2016). On appeal, the defendant argues that the trial court
erred when it: (1) ruled that his testimony opened the door to evidence of his
alleged involvement in an unrelated homicide; (2) denied his motion in limine to
preclude the State from introducing testimony regarding physical and sexual
assaults that occurred during the burglary; (3) allowed the State to introduce
lay testimony from custodians of cellular telephone records regarding the range
of cell towers; and (4) sentenced the defendant on both conspiracy to commit
theft convictions. We affirm in part and vacate in part.

                                         I

      The jury could have found the following facts. At approximately 3:30
p.m. on July 18, 2011, two armed men entered J.U.’s house in Hampstead.
J.U and his friend D.C. were in the house at the time. The intruders
blindfolded and beat the two, while demanding to know where J.U. kept his
guns. J.U. led one assailant to a locked room where he kept some guns and
unlocked the room. Dissatisfied with the guns located in the room, the
intruders demanded more guns. J.U. told them that he had no other guns in
the house. At some point, D.C. was bound and taken into the bathroom, where
she was sexually assaulted by one of the assailants. The other assailant
started to carve his name into J.U.’s back before being stopped by the first
assailant. Neither J.U. nor D.C. could identify the assailants who entered the
house. Both testified, however, that they believed a third person entered the
house at some point; D.C. testified that she “could hear somebody at the front
door handing stuff out and a little bit of whispering,” while J.U. testified that a
third person was “moving stuff out of the back room.” After approximately
forty minutes, the intruders left. J.U. broke free of his bonds, went outside,
and got help from a passerby who called the Hampstead Police.

       The defendant and several other individuals were eventually charged
with participation in the home invasion. At the defendant’s trial, the State
presented evidence that Avery Walker, Holli Soltish, Angel Sanchez, Max
Menagerman, and the defendant conspired to break into J.U.’s home to steal
guns. Soltish testified that she became aware of J.U.’s gun collection through
a friend and described it to Walker, who enlisted the defendant, Menagerman,
and Sanchez to help steal and sell J.U.’s guns.

       The group made several trips to J.U.’s home in preparation for the home
invasion. The first trip occurred on July 11, when Soltish approached J.U. at
his home while the rest of the group waited in a nearby car. The second trip
occurred on July 16, when the defendant, Walker, Menagerman, and Sanchez,
in an effort to learn who occupied J.U.’s home, approached the home posing as
landscapers and feigned confusion about the location of a nearby residence.
J.U. testified that he became suspicious as a result of the July 16 visit and
moved a number of his guns and valuables to another location.

      The State’s theory at trial was that Menagerman, Sanchez, and the
defendant committed the home invasion, with Menagerman and Sanchez
entering the residence while the defendant primarily remained outside in a car.
The State further asserted that Menagerman sexually assaulted D.C., and
Sanchez assaulted J.U. In support of its theory, the State presented testimony


                                        2
from Aneudys Menendez, who said that, after the crime, the defendant and
Sanchez showed him firearms that they had stolen from J.U.’s home.
Menendez also testified that the defendant, Sanchez, and Menagerman asked
him to find buyers for the stolen guns.

      Before trial, the defendant moved to exclude from trial all testimony or
evidence regarding the sexual assault against D.C. and the physical assault
against J.U. He asserted that evidence of the assaults was inadmissible
because he had not been charged with any crime relating to the assaults, and
because the testimony would be inflammatory in nature and was, therefore,
unfairly prejudicial. The State objected, arguing that the assaults were
inextricably intertwined with the acts charged against the defendant, and
therefore, were relevant and integral to J.U.’s and D.C.’s testimony.

      After a hearing, the court concluded, pursuant to New Hampshire Rules
of Evidence 401 and 403, that certain testimony related to the sexual assault
was probative because it placed Menagerman at the scene of the crime and
allowed the jury to better evaluate D.C.’s and Menendez’s testimony. In
addition, it found that testimony regarding the sexual assault was necessary
“to complete the story” of the burglary because the assault occurred
contemporaneously with the home invasion and explained the high degree of
trauma that D.C. experienced. (Quotation omitted.) Although the court
acknowledged that the testimony was prejudicial, it concluded that the
prejudice would be mitigated by providing a limiting instruction to the jury, as
well as by the fact that the defendant was not accused of committing the
assault, which he asserted was “vastly different in nature” from the crimes with
which he was charged. The court determined that the evidence relating to the
physical assault of J.U. was probative for similar reasons, and concluded that
the same mitigating factors would cure any prejudice created by J.U.’s
testimony about that assault.

        At trial, the court gave the following limiting instruction after J.U.
testified regarding the physical assault:

             Relating to the testimony that this witness and other
      witnesses have and will provide in this case about the injury to
      [J.U.’s] back with the knife, and the sexual assault of [D.C.] So as
      I’ve already told you in this case, [the defendant] is not charged
      with either of those crimes.

             The reason that I have allowed that evidence into this case,
      despite the fact that he’s not charged with those crimes, is to allow
      you to evaluate [J.U.’s] and [D.C.’s] testimony, their perceptions,
      memory, emotional state at the time of the observations they made
      in this case so that you can properly understand what was
      happening from each of their testimony to them. The testimony is


                                          3
      to be considered by you only as it impacts these two witnesses’
      perceptions, memory, and the reliability of their testimony.

            So that’s the reason I’m allowing that evidence in, and that’s
      the only reason you should use that evidence for that limited
      purpose in this case.

The trial court reminded the jury after D.C.’s testimony regarding the sexual
assault that such testimony was admitted only for the purpose of evaluating
D.C.’s testimony, and that the defendant had not been charged with those
crimes.

      Also prior to trial, the defendant filed a motion in limine challenging the
admissibility of evidence concerning the location of the cell towers that serviced
the conspirators’ cell phones at certain times, claiming that such evidence
constituted expert testimony and could not be introduced by non-expert
custodians of cell phone records. After a hearing, the court denied the motion,
finding that general “testimony of how calls attach to cellphone towers is within
the ken of the average jury” based on the ubiquity of cell phones and smart
phones in society. (Quotation omitted.)

      The State presented testimony at trial from three cell phone records
custodians who were employed at major cell phone service providers. The first
custodian testified about the collection and storage of cell phone records. The
other two custodians discussed the average and maximum ranges of the cell
towers used by their respective companies, as well as the basic method by
which cell phones connect to cell towers. The State also presented testimony
from an analyst from the New England State Police Information Network, who
reviewed the cell phone records and compared the cell site data to company-
provided maps of the cell tower network. With this information, the analyst
created maps that indicated which cell towers were used by the phones of the
defendant, Menagerman, and Sanchez on July 16 and 18. Based upon the cell
tower information, the maps indicated that the three individuals’ cell phones
were in the vicinity of Hampstead on July 16 as well as at the time of the July
18 home invasion.

      The defendant presented an alibi defense, claiming through his own
testimony and that of other witnesses that he had spent most of July 18 at the
hospital with his wife, who was giving birth to their child. The defendant
admitted to being present on the July 11 Hampstead trip, but testified that he
thought the purpose of the trip was to help the defendant “buy an illegal gun.”
He testified that Sanchez translated what Soltish said, and told him that
Soltish “knew someone who had a license to purchase guns.”

      In response to the defendant’s testimony about his actions on July 11,
the State argued that the defendant had opened the door to evidence of


                                        4
unrelated criminal activity that refuted his claim to be an unwitting accomplice
in the events of that day. The trial court agreed, and allowed the State to
present rebuttal evidence of an unrelated murder that occurred in Manchester
later on July 11 or early the following morning, in which the defendant,
Menagerman, and Sanchez allegedly participated. The rebuttal evidence
consisted of records reflecting that the cell phones of the defendant,
Menagerman, and Sanchez were in Manchester around the time of the murder,
and testimony by Menendez that the defendant and Sanchez, later joined by
Menagerman, had bragged to him about committing the murder while they and
Menendez watched a television news story reporting on that crime. At the close
of all the evidence, the trial court gave the following limiting instruction
regarding the evidence of the murder:

      So ladies and gentlemen, I just had a conversation here about
      instructions that before the parties rested in the case that I had
      intended to give you that I didn’t [a]bout the use of the Manchester
      homicide evidence that you heard in the State’s rebuttal case.

             The evidence was introduced for the purpose of rebutting the
      Defendant’s direct testimony during . . . this trial. You are not
      allowed to use the evidence about his affiliation, if you do find that
      there is one, to that Manchester case to conclude that if you
      conclude that he was involved in that case, you can’t then say well
      he -- if he did that, he must have done the Hampstead case.

            The evidence was introduced solely for the purpose of
      rebutting his testimony. You can’t infer that because he may have
      been involved in other bad conduct, he must have committed the
      Hampstead case. That’s -- the evidence was introduced with a very
      limited purpose of rebutting his testimony.

            And one more point on that . . . , ladies and gentlemen, there
      are no pending charges in connection with the Manchester case.
      So no one has been charged in connection with that Manchester
      homicide.

      Following a nine-day trial, the defendant was convicted of all charges.
This appeal followed.

                                        II

      We first address the defendant’s assertion that the trial court erred in
ruling that his testimony about the July 11 visit to Hampstead opened the door
to rebuttal evidence that he was involved in the Manchester homicide. The
defendant argues that his testimony was not misleading, and that, even if his
testimony was misleading, the court erred by allowing the rebuttal evidence


                                        5
because it was unrelated to the acts for which the defendant was charged and
because it relied upon an improper propensity inference. Moreover, the
defendant contends that the rebuttal evidence –– specifically the testimony that
he allegedly committed a murder and bragged about it afterwards –– is so
unfairly prejudicial that even the trial court’s curative instructions could not
adequately limit the risk of unfair prejudice.

      We have usually considered the evidentiary doctrine of “opening the
door” in the context of two subsidiary doctrines. See State v. Gaudet, 166 N.H.
390, 396 (2014). The first, which we have described as the doctrine of
“curative admissibility,” arises when inadmissible prejudicial evidence has been
erroneously admitted by one party, and the opposing party seeks to introduce
other evidence to counter the prejudice. Id. The second, which we have called
the doctrine of “specific contradiction,” applies more broadly to situations in
which a party introduces admissible evidence that creates a misleading
advantage for that party, and the opposing party is then permitted to introduce
previously suppressed or otherwise inadmissible evidence to counter the
misleading advantage. Id. With respect to this prong, the fact that the “door
has been opened” does not permit all evidence to “pass through” because the
doctrine is intended to prevent prejudice and is not to be subverted into a
vehicle for the introduction of prejudice. Id. (quotation omitted). The specific
contradiction doctrine is at issue in this case.

        “The trial court is in the best position to gauge the prejudicial impact of
particular testimony.” Id. (quotation omitted). Consequently, we review the
trial court’s decision to admit evidence under the “opening the door” doctrine
using our unsustainable exercise of discretion standard. State v. Nightingale,
160 N.H. 569, 579 (2010). To prevail, the defendant must show that the trial
court’s decision was clearly untenable or unreasonable to the prejudice of his
case. See id.

      The defendant asserts that his testimony at trial did not create a
misleading impression because he did not characterize himself as a “wide-eyed
innocent” who never agreed to commit criminal acts, but rather as merely an
individual who was unaware of the criminal purpose of the July 11 trip.

        We have previously held that the door can be opened by inferential
conclusions that may be drawn from a witness’s testimony. See State v.
Cannon, 146 N.H. 562, 565-66 (2001); State v. Carlson, 146 N.H. 52, 57-58
(2001). In Cannon, the defendant was convicted of one count of aggravated
felonious sexual assault. Cannon, 146 N.H. at 563. At trial, the complainant
testified that she rejected the defendant’s advances because she had a
boyfriend, implying that she did not have sexual relations with men other than
her boyfriend. Id. at 563-64. The defendant attempted to introduce testimony
about an incident in which his cousin had consensual sex with the
complainant one or two weeks prior to the alleged assault. Id. at 564. The trial


                                         6
court excluded the testimony. Id. We reversed, concluding that the
complainant’s testimony regarding her reason for rejecting the defendant’s
advances directly affected the issue of consent and thereby opened the door for
the defendant to submit rebuttal evidence on that new issue. Id. at 565-66.

       In Carlson, we concluded that the defendant’s testimony that at some
point during the evening of the assault he said, “I’m leaving. This isn’t me,”
could logically have been interpreted by the jury as an assertion that “it was
not within his character to engage in sexual activity with girls under the age of
legal consent.” Carlson, 146 N.H. at 57. Thus, notwithstanding that there may
also have been other reasonable interpretations of the statement, we held that
the defendant had opened the door to admission of evidence demonstrating
that he had previously had sexual relations with an underage girl. Id. at 57-
58.

       The same reasoning applies here. The defendant stated that he
accompanied the group to Hampstead on July 11 to purchase a gun after
Sanchez had told him that Soltish had said that she knew “someone who had a
license to purchase guns.” The dissent emphasizes the fact that the defendant
said he went to Hampstead to buy an illegal gun, asserting that this is
significant because it refutes the notion that the defendant was attempting to
portray himself as a wholly innocent person. Although we acknowledge that
the transcript of the defendant’s testimony does reflect that he said “illegal”
gun, there is reason to doubt that the transcript is accurate on this point. A
review of the transcript reflects that during the entire discussion between
counsel and the court concerning the State’s request to elicit evidence
regarding the Manchester homicide no mention whatsoever was made about
the defendant testifying that the gun he intended to buy was “illegal.”
Additionally, at the conclusion of that discussion, when the trial court
explained that it was permitting evidence of the homicide to be admitted to
contradict the defendant’s testimony “that the trip to Hampstead was
essentially an innocent trip to buy a gun from a licensed gun dealer,” the
defendant’s counsel made no effort to clarify or correct the court’s statement by
referencing the fact that the defendant had testified he planned to buy an
“illegal” gun. Most importantly, nowhere in his appellate brief addressing the
issue of the asserted error by the trial court in admitting evidence of the
Manchester homicide does the defendant contend that the defendant testified
the gun he allegedly traveled to Hampstead to buy on July 11 was “illegal,” nor
does he advance the position relied upon by the dissent — that his admission
to seeking to purchase a supposedly “illegal” gun shows that he was not
claiming to be in Hampstead on that date for an innocent purpose.

      But even if we accept that the defendant did testify that he planned to
buy an “illegal” gun, the evidence of the Manchester homicide was nonetheless
highly probative of the defendant’s credibility as to his knowledge of the
purpose of the trip. Although the defendant did not explicitly state that he


                                       7
was, as the State claimed, a “wide-eyed innocent,” the defendant’s testimony
intimated that he was “innocent” in the sense that he was unaware of the true
purpose of the group’s July 11 visit because of Sanchez’s inaccurate
translation of Soltish’s statements. That testimony suggests that the defendant
would not have travelled to Hampstead had he known the true purpose of the
trip. This, in turn, could have left the jury with the impression that the
defendant was ignorant of the conspiracy. Thus, by claiming that he thought
the purpose of the trip to Hampstead on July 11 was to buy a gun from
someone, the defendant injected a new issue into the case. The defendant had
no obligation to describe his reasons for joining the group on this trip, nor was
he required to create an impression of himself as a person who merely wanted
to buy a gun (whether legal or illegal). Once he did so, however, he opened the
door for the State to present evidence that rebutted the implications of his
testimony.

        For similar reasons, the defendant’s next contention –– that the evidence
of the unrelated murder should not have been admitted because it does not
specifically contradict his testimony that he did not understand the true
criminal purpose of the July 11 trip –– also is unpersuasive. The defendant
argues that his testimony “could have been specifically contradicted by the
testimony of another occupant of the car [indicating] that Sanchez accurately
translated the conversation,” rather than by testimony that the defendant
“participated in another unrelated crime.” Yet the issue is not merely whether
Sanchez mistranslated the conversation. It is the defendant’s testimony that
he went to Hampstead to purchase a gun, which implies that he did not know
about the conspiracy or the true purpose of the trip because he had been kept
in the dark by his companions. That implication could be rebutted by evidence
presented by the State showing that, only hours after the July 11 trip, the
defendant committed a homicide in Manchester with two members of the
conspiracy, Sanchez and Menagerman, and then bragged about it. There can
be little doubt that a jury, upon learning that Sanchez was willing on the same
day to participate in a murder with the defendant, would find such evidence
highly probative in rebutting the defendant’s implied assertion that Sanchez
mistranslated the conversation to keep him from knowing the true criminal
purpose of the July 11 trip. See State v. Donovan, 120 N.H. 603, 607-08
(1980); see also United States v. Pelletier, 666 F.3d 1, 5-6 (1st Cir. 2011)
(when, through cross-examination of government witness, defense counsel
created impression that defendant had legitimate sources of income and had
nothing to do with delivery of marijuana, which just “mysteriously appeared” in
buyer’s car, trial court properly admitted evidence of defendant’s prior drug
convictions); United States v. Rodriguez, 215 F.3d 110, 119 (1st Cir. 2000) (“By
offering evidence of a second [later] incident in which Santana [one of the
defendants] was involved in a completed drug venture with some of the same
participants, the government gave the jury a reason to view skeptically
Santana’s claim that he was just an innocent bystander who was ‘merely



                                        8
present,’ but rather to conclude that he was a knowing and intentional
participant in the crimes charged in the indictment.”).

       Finally, we turn to the defendant’s claim that the court erred in allowing
the evidence of the Manchester homicide because of its “extraordinarily high
risk of unfair prejudice” that could not be mitigated by a limiting instruction.
In support of his position, he cites several cases in which we held that the
court’s limiting instructions were insufficient to cure the taint of prejudicial
evidence. See, e.g., State v. Ayotte, 146 N.H. 544, 549 (2001); State v. Pelkey,
145 N.H. 133, 137 (2000).

       These cases, however, are factually distinguishable. None of them
involved the “opening the door” doctrine; that is, none involved situations in
which the State introduced rebuttal evidence to respond to an issue injected
into the trial by the defendant’s own testimony. Rather, in those cases, the
State introduced the prejudicial evidence in the first instance. Compare Ayotte,
146 N.H. at 546-48, and Pelkey, 145 N.H. at 135, with State v. Wamala, 158
N.H. 583, 590 (2009), and State v. Taylor, 139 N.H. 96, 99-100 (1994). As we
have recognized, when, as here, a party introduces admissible evidence that
creates a misleading advantage for that party, the opposing party has a
particularly strong interest in being able to refute such evidence. See State v.
Blackstock, 147 N.H. 791, 797 (2002). Were the rule otherwise, a party could
theoretically enjoy a license to make affirmative misrepresentations and
commit perjury without fear of contradiction. See Taylor, 139 N.H. at 100; see
also Blackstock, 147 N.H. at 797 (holding that trial court sustainably exercised
its discretion in ruling that, if defendant chose to expose witness’s bias against
him, State would be permitted to elicit from witness basis for bias). Thus, we
do not believe that the cases cited by the defendant are persuasive in the
instant case.

       As we have often noted, evidence is not precluded from admission merely
because it is prejudicial, in the sense that it tends to prove facts that are
detrimental to the opposing party’s position, for in this sense all relevant
evidence offered by the prosecution is meant to be prejudicial. See Nightingale,
160 N.H. at 574; State v. Cassavaugh, 161 N.H. 90, 98 (2010). Instead, to be
excluded, the evidence must be unfairly prejudicial, which typically means that
it has an undue tendency to provoke a decision by the jury based upon
emotion, anger, bias, sympathy or some other grounds aside from the
“established propositions” of law in the case. See Nightingale, 160 N.H. at 574-
75; Cassavaugh, 161 N.H. at 98. Although we acknowledge that admission of
evidence of the Manchester homicide carried a risk of undue prejudice, we
believe the risk was significantly reduced by the trial court’s clear and proper
limiting instructions, which the jury is presumed to have followed, explaining
that the sole purpose of introducing the testimony relating to the Manchester
murder was to rebut the defendant’s testimony, and that this evidence could
not be used for the purpose of inferring that the defendant must have


                                        9
committed the crimes at issue because he had a propensity to engage in
criminal conduct. See Gaudet, 166 N.H. at 397.

      Accordingly, we conclude that the trial court’s decision to admit the
evidence about the Manchester homicide was not an unsustainable exercise of
discretion.

                                       III

      The defendant next argues that the trial court erred under New
Hampshire Rules of Evidence 401 and 403 by admitting evidence of the
physical and sexual assaults against J.U. and D.C. Although the defendant
concedes that the evidence of the physical and sexual assaults possesses some
probative value under Rule 401, he maintains that the probative details of the
assault, such as D.C.’s testimony that her attacker repeatedly sneezed while
attacking her, could have been discussed without reference to the assaults
themselves. Moreover, the defendant asserts that the minimal degree of
probative value was substantially outweighed by the danger of unfair prejudice
because of the heinous and extreme details of the assaults, which were
highlighted by statements in the State’s closing argument. Finally, the
defendant argues that the three considerations offered by the court in its
decision, including its limiting instruction, were insufficient to cure the
inflammatory nature of the evidence.

       According to Rule 401, evidence is relevant if it has “any tendency to
make the existence of any fact that is of consequence to the determination of
the action more probable or less probable than it would be without the
evidence.” N.H. R. Ev. 401. Under Rule 403, however, even “relevant . . .
evidence may be excluded if its probative value is substantially outweighed by
the danger of unfair prejudice, confusion of the issues, or misleading the jury,
or by considerations of undue delay, waste of time, or needless presentation of
cumulative evidence.” N.H. R. Ev. 403; see State v. Willis, 165 N.H. 206, 216
(2013). As we explained, unfair prejudice is not mere detriment to a defendant
from the tendency of the evidence to prove guilt, in which sense all evidence
offered by the prosecution is meant to be prejudicial. Willis, 165 N.H. at 216.
Rather, the prejudice required to predicate reversible error is an undue
tendency to induce a decision against the defendant on some improper basis,
commonly one that is emotionally charged. Id. Among the factors we consider
in weighing the evidence are: (1) whether the evidence would have a great
emotional impact upon a jury; (2) its potential for appealing to a juror’s sense
of resentment or outrage; and (3) the extent to which the issue upon which it is
offered is established by other evidence, stipulation, or inference. Id.

      “The trial court is in the best position to gauge the prejudicial impact of
particular testimony, and what steps, if any, are necessary to remedy that
prejudice.” Id. (quotation omitted). Thus, we give the trial court broad latitude


                                       10
when ruling on the admissibility of potentially unfairly prejudicial evidence,
and we will not disturb the trial court's decision absent an unsustainable
exercise of discretion. Id.

       To perform the balancing required by Rule 403, we first consider the
probative value of the evidence. See Wells, 166 N.H. at 80. Here, the evidence
relating to the assaults was relevant to the identities of the individuals who
participated in the conspiracy with the defendant. As the trial court found,
because one of the assailants carved “what could be the beginning of an ‘A’”
into J.U.’s back, the testimony about the physical assault was probative of
Sanchez’s identity as one of the co-conspirators. Similarly, the fact that D.C.’s
assailant repeatedly sneezed in the bathroom containing a cat box connects
Menagerman, who is allergic to cats, to the conspiracy and burglary.

       Moreover, as the trial court found, the assaults were contemporaneous to
and inextricably intertwined with the home invasion. See id. at 78 (explaining
that when evidence of “other act” and evidence of crime are inextricably
intertwined, “other act” evidence is admissible because “events do not occur in
a vacuum, and the jury has a right to hear what occurred immediately prior to
and subsequent to the commission of the charged act so that it may
realistically evaluate the evidence” (quotation omitted)). As the trial court
noted, the reliability of witness testimony is always relevant, and the evidence
of the assaults was necessary in order for the jury to understand the trauma
that D.C. and J.U. experienced, and how that trauma affected their
observations of the home invasion. See State v. Germain, 165 N.H. 350, 359
(2013), modified in part on other grounds by State v. King, 168 N.H. 340, 345
(2015). It is doubtful that the victims could have excluded the assaults from
their retelling of the home invasion without appearing overly emotional, which
may have jeopardized their credibility with the jury. Cf. State v. Giles, 140
N.H. 714, 718-19 (1996) (noting that the witness’s tone of voice and demeanor
are two useful tools in the jury’s assessment of credibility). Thus, the
testimonies of the assaults carried a high degree of probative value.

      We next consider whether the danger of unfair prejudice to the defendant
from the admission of this testimony substantially outweighed its probative
value. See Wells, 166 N.H. at 80. The evidence about the assaults
undoubtedly carried the potential to inflame the jury against the offenders
because of the nature of those crimes. Yet the defendant did not participate in
the assaults and, notwithstanding the defendant’s close connection to the
assailants and his possible presence in the house during some of the time
when the assaultive conduct occurred, there was no evidence that he witnessed
or knew of either of the assaults. Furthermore, the dissimilarity between the
conduct attributed to the defendant, on the one hand, and the far more
egregious conduct attributed to Sanchez and Menagerman, on the other,
lessened the risk of unfair prejudice. Although we recognize that there are
cases in which a limiting instruction cannot sufficiently reduce the risk of


                                       11
unfair prejudice, see Pelkey, 145 N.H. at 137, here, the trial court’s multiple
limiting instructions, taken together with the above-mentioned considerations,
sufficiently reduced the risk of unfair prejudice arising from the testimony
about the assaults. Consequently, despite the prejudicial nature of the
assaults, we cannot conclude that the evidence was so inflammatory as to
substantially outweigh its probative value. Thus, we hold that the trial court
did not unsustainably exercise its discretion in admitting evidence of the
physical and sexual assaults.

                                               IV

       We next address the defendant’s contention that the trial court erred in
admitting evidence about the range of cell towers. We review the trial court’s
ruling to determine whether it was an unsustainable exercise of discretion.
State v. Gonzalez, 150 N.H. 74, 77 (2003). We will reverse the trial court “only
if the appealing party can demonstrate that the ruling was untenable or
unreasonable and that the error prejudiced the party’s case.” Id. (quotation
omitted).

       The defendant argues that details pertaining to a cell phone tower’s
operation, “especially . . . the maximum radius of cell phone towers and the
selection preference for the nearest tower, did not fit within the definition of lay
testimony,” and thus constituted expert testimony, which the records
custodians who appeared at the trial were unqualified to provide.1

      New Hampshire Rule of Evidence 701 states that opinion testimony by
lay witnesses must be “limited to those opinions or inferences which are (a)
rationally based on the perception of the witness, and (b) helpful to a clear
understanding of the testimony or the determination of a fact in issue.” N.H.
R. Ev. 701. Conversely, expert testimony involves “matters of scientific,
mechanical, professional or other like nature, which requires special study,
experience, or observation not within the common knowledge of the general
public.” Gonzalez, 150 N.H. at 77 (quotation omitted).

       Although this issue is one of first impression for this court, courts in
other jurisdictions have addressed it, and several have “treated historical cell
site data analysis as proper lay testimony under certain conditions.” State v.
Johnson, No. 16-0265 2017 WL 878720, at *8 (W. Va. Mar. 2, 2017).2 We note

1 The State argues that “certain aspects” of the defendant’s argument were not preserved for our
review, specifically his arguments relating to the testimony about the maximum range of the cell
towers and the fact that cell phones attach to the closest available tower. However, the record
establishes that the defendant objected to this testimony in a motion in limine, reiterated those
concerns in a motions hearing before the court, and then renewed his objection at trial. Thus, we
hold that the defendant’s argument is preserved for our review.
2 See, e.g., United States v. Graham, 796 F.3d 332, 364-65 (4th Cir. 2015), adopted in relevant

part by 824 F.3d 421, 424 n.1 (4th Cir. 2016), appeal docketed, No. 16-6308 (U.S. Oct. 4, 2016);


                                               12
that Federal Rule of Evidence 701 is similar to our state rule, compare Fed R.
Evid. 701 with N.H. R. Ev. 701, and, therefore, we look to federal cases for
guidance. In United States v. Kale, 445 F. App’x 482 (3d Cir. 2008), the court
held that a cell phone records custodian’s “limited discussion of the operation
of cell phone towers” did not constitute expert testimony because it consisted of
“reading and interpreting [the defendant’s] cell phone records, including
records detailing the locations of cell towers used to carry out his phone calls.”
Kale, 445 F. App’x at 485.3 The court concluded that “a person of average
intelligence would almost certainly understand that the strength of one’s cell
phone reception depends largely on one’s proximity to a cell phone tower.” Id.
Furthermore, the court found that the custodian possessed sufficient “personal
knowledge” regarding the operation of cell towers because of his training and
experience. Id. (quotation omitted).

      We have previously found that individuals can present limited lay
testimony regarding matters which, if discussed in detail, would require expert
testimony. See, e.g., State v. Cochrane, 153 N.H. 420, 423 (2006). In
Cochrane, for instance, the defendant appealed his conviction for driving while
intoxicated. Id. at 420. He argued that the arresting police officer’s testimony
regarding the administration and interpretation of the Horizontal Gaze


United States v. Feliciano, 300 F. App’x 795, 801 (11th Cir. 2008); Woodward v. State, 123 So. 3d.
989, 1016-17 (Ala. Crim. App. 2011); Perez v. State, 980 So. 2d 1126, 1131-32 (Fla. Dist. Ct. App.
2008). But see Wilder v. State, 991 A.2d 172, 197-200 (Md. Ct. Spec. App. 2010); Collins v. State,
172 So. 3d 724, 743-44 (Miss. 2015); State v. Patton, 419 S.W.3d 125, 132 (Mo. Ct. App. 2013).
3 The defendant cites United States v. Guerrero, 768 F.3d 351 (5th Cir. 2014), to support his

claim that testimony regarding the “maximum range of cell phone towers” must be presented by
an expert. In Guerrero, the Fifth Circuit Court of Appeals held that an expert witness was
adequately qualified to “interpret[] the historical cell site information that indicated where [the
defendant] was when he placed calls.” Guerrero, 768 F.3d at 356-57, 365. However, the court
did not elucidate whether the expert testified as to the precise location of the defendant
(something which the trial court here acknowledged would require expert testimony), his general
location in relation to the cell towers, or some other matter. See id. Absent such elucidation,
Guerrero holds no persuasive value for the case at bar.
         The defendant also relies on three state cases, most notably Wilder v. State, 991 A.2d 172,
198 (Md. Ct. Spec. App. 2010), to support his assertion. We find those cases unpersuasive.
Wilder relied upon Md. Rule 5-702, which contains substantially different language than N.H. R.
Ev. 702. See Wilder, 991 A.2d at 200. Compare Md. Rule 5-702 with N.H. R. Ev. 702. Wilder
also followed prior Maryland precedent, which interprets the permissible bounds of lay testimony
more restrictively than we have, as evidenced by our decision in Cochrane, discussed in the text.
In the second case cited by the defendant, Wilson v. State, 195 S.W.3d 193 (Tex. App. 2006), the
Texas Court of Appeals held only that a trial court did not err by admitting a cell phone records
custodian’s testimony because the witness possessed sufficient specialized knowledge to be
qualified as a reliable expert. Wilson, 195 S.W.3d at 202. The pertinent issue was whether that
particular witness qualified as an expert, not whether a cell phone records custodian could
discuss, as a lay witness, elementary concepts relating to the range and operation of cell towers.
See id. at 200-02. In the third case, State v. Manzella, 128 S.W.3d 602 (Mo. Ct. App. 2004), the
Missouri Appeals Court affirmed the trial court’s determination that the defendant was
unqualified to provide expert testimony about cell towers based upon his “life experiences and ten
years as a customer” of a cell phone provider. Manzella, 128 S.W.3d at 609.


                                                13
Nystagmus4 (HGN) test was expert testimony. Id. at 421. We acknowledged
that the “scientific and neurological mechanisms behind the effects of alcohol
on the nervous system and the phenomenon of nystagmus are specialized and
highly technical and . . . [t]herefore, testimony regarding these mechanisms
would qualify as expert testimony.” Id. at 423. We held, however, that an
officer’s testimony regarding “(1) his or her training and experience in
administering and scoring the HGN test based upon the National Highway
Traffic Safety Administration (NHTSA) standards and guidelines; (2) the
administration of the HGN test in a particular case; and (3) the results of the
HGN test as established by the NHTSA standards and guidelines” constituted
lay testimony. Id. (emphasis added). The defendant correctly points out that
our conclusion in Cochrane arose partially from the officer’s personal
observations; however, his argument disregards the fact that the officer’s
observations during the HGN test were enabled by the officer’s specialized
training and experience. See id. at 423.

       Given the cell phone records custodians’ specialized training and
experience interpreting cell phone records, we hold that the custodians could
testify as lay witnesses because they possessed sufficient personal knowledge
to discuss generally the means by which cell phones connect to the closest cell
tower and the general ranges of cell towers. See Kale, 445 F. App’x at 485-86.
Moreover, we agree with the trial court’s conclusion that the ubiquity of cell
phones and cell towers in society allows the average juror to understand the
elementary concepts underlying the interactions between cell phones and cell
towers. Such understanding is qualitatively different from understanding the
scientific and neurological mechanisms of the effects of alcohol on the nervous
system referred to in Cochrane, which are wholly beyond the ken of the average
juror. Accordingly, we conclude that the trial court did not unsustainably
exercise its discretion in admitting the records custodians’ testimony regarding
the range of cell towers.

                                                V

      Finally, the defendant asserts that the trial court erred in sentencing him
on both of the conspiracy indictments. Although the State’s theory at trial was
that the defendant and his co-conspirators participated in a single overall plan
to commit the home invasion, of which the two reconnaissance or “casing” trips
to Hampstead were a part, the State indicted the defendant for participating in
two separate conspiracies. The first conspiracy indictment focused on the July
11 reconnaissance trip, while the second focused on the July 16
reconnaissance trip. The defendant argues that because the evidence showed
that there was in fact a single conspiracy, the trial court’s imposition of
consecutive seven and one-half to fifteen year sentences for each conspiracy

4 Nystagmus is an “involuntary, rapid, back-and-forth jerking of the eyes,” and is associated with
alcohol consumption. Cochrane, 153 N.H. at 421-22, 423.


                                                14
conviction violates the double jeopardy protections provided by the United
States and New Hampshire Constitutions. Because the defendant did not
present this issue to the trial court, he raises it before us as a matter of plain
error. See Sup. Ct. R. 16-A.

      The State concedes that, under the facts and circumstances of this case,
it was plain error for the trial court to sentence the defendant on both
conspiracy convictions. Accordingly, we vacate the defendant’s conviction on
one of the conspiracy indictments.

                                                    Affirmed in part; and
                                                    vacated in part.

     DALIANIS, C.J., and HICKS, J., concurred; CONBOY and BASSETT, JJ.,
concurred in part and dissented in part.

       CONBOY, J., concurring in part and dissenting in part. I concur in the
conclusions set forth in Sections III, IV, and V of the majority’s opinion. I
disagree, however, with the majority’s conclusion in Section II that the trial
court did not err in ruling that the defendant’s testimony about the July 11
visit to the Hampstead home, prior to the July 18 invasion of the home, opened
the door to evidence that he was involved in a Manchester homicide. Because I
conclude that the admission of this testimony was error and that this error was
not harmless, I respectfully dissent.

      During trial, in response to defense counsel’s question as to whether he
had ever been to the “house in Hampstead,” the defendant testified that he
thought the purpose of the July 11 visit was to buy an illegal gun. He said:

      Angel Sanchez had translated something that [Holli Soltish] had
      said. I want[ed] to buy an illegal gun. And she proposed to Angel
      that she knew someone who had a license to purchase guns. And
      she brought me to this place in New Hampshire. And she told me
      that she was going to talk to that person.

(Emphasis added.) Subsequently, the State argued that the defendant’s
testimony portrayed him as a “wide-eyed innocent” with respect to the July 11
trip, and, therefore, the defendant had “open[ed] the door to the other acts,” “to
other information that he would have been aware of, because he was involved.”

       The trial court agreed with the State, ruling that the defendant’s
“testimony about being at the scene in Hampstead for a wholly innocent
reason” opened the door to testimony about “his involvement in other cases.”
Specifically, the court ruled that the defendant had opened the door to allow
the State



                                         15
      to show that he was fully part of this plan to engage in these home
      invasions, that he knew full well why they were going there,
      because he had done it before, and he did it again. And this is
      part of the pattern of conduct that he and the other two
      [conspirators] are engaged in.

       The State subsequently asked the defendant whether he had been
questioned about a murder in Manchester, and whether he was investigated
“for [a separate] home invasion,” but it did not question him about the details
of his involvement in either crime. Later, the court ruled that it would not
allow rebuttal evidence regarding other home invasions, but that it would allow
evidence of the Manchester homicide. It stated that

      the evidence the State proffered . . . with respect to the Manchester
      homicide is tightly tied to the purpose of the trip on July 11th. It
      is very close in time. It is within hours of that trip. There is
      specific information that the Defendant was involved in that both
      from [Aneudys] Menendez’[s] testimony that [the defendant]
      bragged about it afterwards and the affiliate, the timing of it, and
      the affiliation of the phones with that location where the homicide
      occurred. So I think that that evidence does go directly to
      contradict [the defendant’s] testimony that that trip to Hampstead
      was essentially an innocent trip to buy a gun from a licensed gun
      dealer.

Thus, although the defendant testified that his goal on July 11 was to buy an
illegal gun, the trial court nonetheless concluded that the defendant’s
testimony conveyed two possible misimpressions: (1) “that [the] trip to
Hampstead was innocent,” or (2) that the defendant “misunderstood the
purpose of why they were going there.” Accordingly, the trial court allowed the
State, on rebuttal, to call Menendez.

        Menendez testified that the defendant and Sanchez showed him a video
“news clipping” about the homicide and “were just bragging about they
murdered a man the previous night or something like in those terms.” He
testified that he learned that “[i]t was suppose[d] to be a . . . robbery, or a drug
or a hit,” but that “[t]he man reacted a way that they didn’t like and they
opened fire on him.” He stated that “[t]hey showed [the video] to me like three
times because they kept going back, showing me specific places where they
stood and, you know, what the house looked like or the porch and, you know,
this happened, that happened type of thing.”

      The majority concludes that, pursuant to the specific contradiction
doctrine, the defendant’s testimony opened the door to Menendez’s testimony,
as well as to other evidence regarding the Manchester homicide, by creating a
misleading impression that “he did not know about the [theft by unauthorized


                                         16
taking] conspiracy or the true purpose of the [July 11] trip because he had
been kept in the dark by his companions.” It explains that

      by claiming that he thought the purpose of the trip to Hampstead
      on July 11 was to buy a gun from someone, the defendant injected
      a new issue into the case. The defendant had no obligation to
      describe his reasons for joining the group on this trip, nor was he
      required to create an impression of himself as a person who merely
      wanted to buy a gun (whether legal or illegal). Once he did so,
      however, he opened the door for the State to present evidence that
      rebutted the implications of his testimony.

       For the specific contradiction doctrine to apply, a party must introduce
evidence that provides a justification, beyond mere relevance, for the
opponent’s introduction of evidence that may not otherwise be admissible.
State v. Wamala, 158 N.H. 583, 589-90 (2009). The initial evidence must,
however, have reasonably misled the fact finder in some way. Id. at 590. The
rule thus prevents a party from successfully excluding evidence favorable to his
opponent, and then selectively introducing this evidence for his own advantage,
without allowing the opponent to place the evidence in proper context. State v.
Bird, 161 N.H. 31, 35 (2010); see also State v. Carlson, 146 N.H. 52, 56 (2001).
The fact that the door has been opened, however, “does not, by itself, permit all
evidence to pass through. The doctrine is to prevent prejudice and is not to be
subverted into a rule for injection of prejudice.” State v. Trempe, 140 N.H. 95,
99 (1995) (quotation omitted).

       Given all of the circumstances, I cannot conclude that the admission of
the Manchester homicide evidence is supportable under the specific
contradiction doctrine. The State contends that “a statement that the
defendant did not understand the criminal purpose of the group’s trip to
Hampstead can create the impression that he did not understand the criminal
purpose because he did not generally engage in criminal activity.” However,
the record contradicts this contention. The defendant testified that he
“want[ed] to buy an illegal gun.” (Emphasis added.) This testimony cannot
fairly be characterized as an effort by the defendant to portray himself as
someone who generally does not engage in criminal activity. Nor did he
suggest, as the trial court concluded, that he was “at the scene in Hampstead
for a wholly innocent reason.”

       I recognize that the majority correctly observes that the defense did not
at trial, and does not on appeal, rely upon the defendant’s testimony that he
wanted to buy an illegal gun. Nonetheless, I cannot ignore the record
testimony, and in the absence of evidence or even argument that there was a
transcript error, I decline to so speculate. Further, I note that following the
defendant’s statement that his goal was to buy an illegal gun, the defendant



                                       17
admitted upon questioning by his counsel, that he did not have a license, and
had not applied for a license, to carry a gun in Massachusetts.

       Even assuming, however, that the defendant did not use the word
“illegal” in referring to the gun he planned to purchase, and that his testimony
created a misleading impression regarding his understanding of the purpose of
the July 11 trip to Hampstead, I do not believe that Menendez’s testimony
regarding a subsequent, unrelated homicide placed the defendant’s testimony
in its “proper context” or otherwise dispelled that misleading impression. See
State v. Lopez, 156 N.H. 416, 423 (2007) (concluding that evidence that New
Hampshire police officer did not see tears on defendant during interview would
not have been placed in its proper context by introducing evidence that
defendant cried at a different interview with New Jersey police on a different
day). Unlike the cases upon which the majority relies, in which the proffered
evidence specifically contradicted certain trial testimony, see State v. Cannon,
146 N.H. 562 (2001); Carlson, 146 N.H. at 52, Menendez’s testimony regarding
the defendant’s alleged involvement in the Manchester homicide did not
specifically contradict the defendant’s testimony regarding his understanding
of the purpose of the July 11 trip to Hampstead.

       In Cannon, a sexual assault case, the complainant testified at trial that
she told the defendant “no” and did not consent to sexual relations with him
because she had a boyfriend. Cannon, 146 N.H. at 563-64. On appeal, the
defendant argued that the trial court erred by excluding testimony that the
complainant had had consensual sexual relations with someone other than her
boyfriend one or two weeks prior to the alleged assault for which the defendant
was being tried. Id. We agreed, concluding that, although the complainant
“had no obligation to explain her reasoning for not consenting,” once she
offered an explanation at the request of the State, “the defendant was entitled
to present evidence to refute her assertion.” Id. at 565.

        In Carlson, the defendant appealed his conviction of felonious sexual
assault for unlawfully engaging in sexual penetration with a person who was
under the age of sixteen. Carlson, 146 N.H. at 52. At trial, the defendant
testified that, at some point during the evening of the assault, he said, “I’m
leaving. This isn’t me.” Id. at 56 (quotation omitted). On appeal, the
defendant argued that the trial court erred in ruling that this testimony had
opened the door to testimony that he had previously engaged in sexual
intercourse with an underage female. Id. at 54, 56. We concluded that the
jury could have viewed his “statement as an assertion that his conduct and
intentions that night were an anomaly and that he was not of a character to
engage in those activities,” id. at 57, and, therefore, the trial court did not err
in ruling that he had opened the door to testimony that he had previously
engaged in sexual relations with underage females, id. at 57-58.




                                         18
       Here, evidence that the defendant participated in a subsequent homicide
with the theft conspirators did not specifically refute any misleading
impression created by his testimony regarding his knowledge of the true
purpose of the earlier Hampstead trip. Without more, it does not logically
follow that, because there was evidence that the defendant participated in the
homicide, he was aware of the purpose of the Hampstead trip. Cf. State v.
Bassett, 139 N.H. 493, 500 (1995) (“The problem is that even if the accused
entertained a certain intent during a similar uncharged incident, the accused
may not have formed that intent on the charged occasion.” (quotation and
brackets omitted)).

       As we have long held, and continue to maintain, evidence of other
wrongs is inadmissible to prove disposition to commit such acts. See Trempe,
140 N.H. at 99 (addressing the admission of prior bad act evidence pursuant to
the opening the door doctrine); see also N.H. R. Ev. 404(b). To be relevant,
evidence of other bad acts must support a reliable inference, not dependent
upon the defendant’s character or propensity, that the defendant was aware of,
and participated in, the charged acts as well as the uncharged acts. See
Bassett, 139 N.H. at 499 (considering whether trial court erred in admitting
evidence of defendant’s prior conviction and sentence to prove intent to commit
the charged crimes); see also N.H. R. Ev. 404(b). In this case, the inference the
State sought to have the jury draw would be reliable only if there was sufficient
support for a conclusion that the defendant’s purported participation in the
Manchester homicide (for which, at the time of trial, the defendant had not
been charged) and his knowledge of the purpose of the trip to Hampstead were
“closely connected by logically significant factors.” Bassett, 139 N.H. at 499.
Although temporal proximity between charged and uncharged bad acts is one
factor to be considered, it cannot, alone, support a reliable inference of shared
knowledge. See id.

      The majority cites United States v. Pelletier, 666 F.3d 1 (1st Cir. 2011),
and United States v. Rodriguez, 215 F.3d 110 (1st Cir. 2000), to support its
conclusion that the Manchester homicide evidence properly rebutted the
defendant’s testimony about the July 11 trip. These cases, however, are
factually distinguishable from this case.

       In Pelletier, the defendant “was convicted of various counts related to his
role in the importation, possession and distribution of marijuana.” Pelletier,
666 F.3d at 3. On appeal, the defendant argued that admission of evidence
regarding his prior drug-related convictions violated Federal Rules of Evidence
403 and 404(b). Id. at 5. The First Circuit Court of Appeals disagreed,
concluding that defense counsel’s “cross-examination of government witnesses
opened the door to introduction of [the defendant’s] prior [drug-related]
convictions.” Id. at 5. The court found that “defense counsel’s questioning
raised the specter of [the defendant] having legitimate sources of income, and
of not taking part in the delivery of marijuana which ‘mysteriously appeared’ in


                                        19
a buyer’s car.” Id. at 5-6. The court explained that, “[i]n the context of drug
conspiracy cases, [it has] found prior convictions probative of knowledge and
intent where they indicate a prior relationship between conspirators, and where
they may be relevant to the defendant’s knowledge of the presence of
contraband and intent to distribute.” Id. at 6 (citations omitted). The court
found that, given the defendant’s “apparent defense, these issues were squarely
— even if only implicitly — placed before the jury,” and, therefore, the district
court did not err by admitting the defendant’s prior convictions. Id.

       Similarly, in Rodriguez, the defendants were convicted of conspiring to
import marijuana and attempting to import marijuana. Rodriguez, 215 F.3d at
114. On appeal, they argued that the district court improperly admitted
“testimony about other drug importation efforts in which one or more of them
participated.” Id. at 118. At trial, one of the defendants claimed that “he was
just a fisherman who liked the waters off St. Thomas and who was innocently
caught up with others who, if they intended a crime, had not told him their
purpose.” Id. at 119. The government introduced “evidence of a second
incident in which [that defendant] was involved in a completed drug venture
with some of the same participants.” Id. The First Circuit Court of Appeals
held that the district court did not err by admitting such evidence pursuant to
Federal Rule of Evidence 404(b) “as possible proof of ‘opportunity, intent,
preparation or common plan, knowledge or absence of mistake, accident or
other innocent reason’ for the defendants’ activities.” Id. at 120.

       In Rodriguez and Pelletier, the court upheld the admission of factually
similar prior convictions to show opportunity, intent, preparation or common
plan, knowledge or absence of mistake with respect to the crime charged, see
Pelletier, 666 F.3d at 5; Rodriguez, 215 F.3d at 120, whereas, here, the
Manchester homicide evidence — factually distinct from the theft conspiracy —
was admitted solely to counter the implication that the defendant was unaware
of the specific criminal purpose of the July 11 trip. I do not believe that the
evidence of the Manchester homicide is “closely connected by logically
significant factors” to the defendant’s supposed understanding of the purpose
of the July 11 trip as to support a permissible inference that contradicts any
impression — misleading or otherwise — created by the defendant’s testimony.
See Bassett, 139 N.H. at 499. The record discloses no evidence that the
defendant and the other members of the theft conspiracy also conspired to
commit homicide. Nonetheless, even if there was evidence of a separate
homicide conspiracy, such evidence would not rebut the impression that the
defendant did not know the true purpose of the July 11 trip unless there was
evidence that the homicide and the theft by unauthorized taking were part of a
common plan or scheme. See Rodriguez, 215 F.3d at 119-20; Trempe, 140
N.H. at 99; see also N.H. R. Ev. 404(b). There was no evidence that the two
crimes were part of a common plan or scheme. Under these circumstances,
which also risked the jury deciding a homicide “trial within a trial,” I conclude



                                       20
that the relevance of the homicide evidence is based upon an improper
character inference. See N.H. R. Ev. 404(b).

        Further, any concern by the State that the defendant misled the jury as
to his awareness of the true purpose of the July 11 trip presumably could have
been addressed by the State calling another witness who participated in the
trip to contradict the defendant’s testimony. See Trempe, 140 N.H. at 99
(holding that trial court erred by allowing evidence of separate, unrelated
interview in which the defendant was asked about a simple assault against his
niece because, although defendant’s testimony created misleading impression
that he had not been contacted by any police officers, prosecutor could have
dispelled impression in other ways). “Opening the door is one thing. But what
comes through it is another. Everything cannot come through the door.”
Gordon v. United States, 783 A.2d 575, 587 (D.C. 2001) (quotation omitted).
As we have stated, the purpose of the doctrine is to prevent prejudice and
should not be subverted into a rule for injection of prejudice. Trempe, 140
N.H. at 99. Here, admission of the Manchester homicide evidence ran directly
counter to this purpose. In my view, instead of rebutting the impression
created by the defendant’s testimony, the evidence served only to introduce
prejudice. Because the Manchester homicide evidence did not fairly place in its
proper context or specifically contradict any misleading impression created by
the defendant as to his knowledge of the true purpose of the prior Hampstead
trip, I would hold that the trial court erred by admitting evidence of the
defendant’s alleged involvement in the subsequent unrelated homicide.

      The State contends that, even if the trial court erred, the error was
harmless. In order to prove harmless error, the State must establish beyond a
reasonable doubt that the erroneously admitted evidence did not affect the
verdict. State v. Botelho, 165 N.H. 751, 756 (2013).

      The evaluation of whether this standard has been achieved
      involves consideration of the [other] evidence presented at trial and
      of the character of the inadmissible evidence itself. An error may
      be harmless beyond a reasonable doubt if the alternative evidence
      of the defendant’s guilt is of an overwhelming nature, quantity, or
      weight, and if the inadmissible evidence is merely cumulative or
      inconsequential in relation to the strength of the State’s evidence of
      guilt.

State v. Vandebogart, 139 N.H. 145, 157-58 (1994) (quotations and citations
omitted).

       Here, given the nature of the erroneously admitted evidence, I conclude
that the State has failed to establish that its admission did not affect the
verdict. I believe that Menendez’s testimony regarding the defendant’s
participation in the homicide “may have tempted the jury to condemn the


                                       21
defendant for uncharged felonies.” State v. Carter, 140 N.H. 1, 5 (1995). It
may also have induced the jury to conclude that because the defendant
participated in the homicide, he probably participated in the theft by
unauthorized taking conspiracy. See id. Moreover, given the “odious and
provocative nature” of Menendez’s testimony, I do not believe that the trial
court’s limiting instruction cured the prejudicial effect of the evidence. See id.
Thus, I cannot conclude that the Manchester homicide evidence was
“inconsequential in relation to the strength of the State’s evidence of guilt.”
State v. Smith, 141 N.H. 271, 280 (1996) (quotation omitted).

       Accordingly, although I believe that the evidence apart from the
Manchester homicide evidence would be sufficient to support a finding of guilt,
I cannot say, beyond a reasonable doubt, that the erroneously admitted
evidence did not affect the verdict. See State v. Crosby, 142 N.H. 134, 139
(1997) (“In determining whether an error was harmless, we ask not whether the
evidence, apart from that erroneously admitted, would support a finding of
guilt, but whether it can be said beyond a reasonable doubt that the
inadmissible evidence did not affect the verdict.” (quotation omitted)); see also
Smith, 141 N.H. at 280 (concluding that admission of defendant’s prior bad
checks convictions was harmless because it did not involve acts of an “odious
or provocative nature, such as sexual assault or homicide” (quotation, citation
and brackets omitted)). Therefore, I would reverse the defendant’s convictions
and remand for a new trial.
