              Appeal from the Judgment of Sentence, July 5, 2017,
                in the Court of Common Pleas of Chester County
                Criminal Division at No. CP-15-CR-0001977-2016


BEFORE: BENDER, P.J.E., OLSON, J., AND FORD ELLIOTT, P.J.E.


MEMORANDUM BY FORD ELLIOTT, P.J.E.:                    FILED JULY 25, 2019

        Gartor Brown appeals from the July 5, 2017 aggregate judgment of

sentence of 11½ to 23 months’ imprisonment imposed after a jury found him

guilty of burglary, theft by unlawful taking or disposition, and criminal

trespass.1 After careful review, we affirm the judgment of sentence.

        The relevant facts and procedural history of this case, as gleaned from

the certified record, are as follows: On April 5, 2016, appellant was charged

with burglary and related offenses2 in connection with a break-in that occurred

in Pocopson Township, Chester County on August 10, 2015. The owner of the




1   18 Pa.C.S.A. §§ 3502(a)(2), 3921(a), and 3503(a)(1)(i), respectively.

2 Appellant was charged with burglary, theft by unlawful taking or disposition,
criminal trespass, and receiving stolen property. The charge of receiving
stolen property, 18 Pa.C.S.A. § 3925(a), was withdrawn prior to trial.
J. S17045/19

burglarized residence, Kristen Giacchino-Doherty, indicated to police that her

bedroom had been ransacked and two jewelry boxes, her passport, two

designer bags, and several pieces of jewelry had been stolen.          (Notes of

testimony, 1/30/17 at 51-52, 54-66.) The majority of these items were later

recovered in the home in Upper Darby, Pennsylvania, where appellant was

residing at the time. (Notes of testimony, 1/31/17 at 28-31.)

      Appellant proceeded to a jury trial on January 30, 2017. Following a

two-day trial, the jury found appellant guilty of burglary, theft by unlawful

taking or disposition, and criminal trespass.       As noted, the trial court

sentenced appellant to an aggregate term of 11½ to 23 months’ imprisonment

on July 5, 2017. Appellant did not file any post-sentence motions. This timely

appeal followed on August 4, 2017.      On August 10, 2017, the trial court

ordered appellant to file a concise statement of errors complained of on appeal

in accordance with Pa.R.A.P. 1925(b). Following an extension, appellant filed

his Rule 1925(b) statement on October 27, 2017, and the trial court issued its

Rule 1925(a) opinion on September 10, 2018.3

      Appellant raises the following issues for our review:

            I.    Did the trial court err in admitting evidence that
                  [a]ppellant had identification belonging to
                  another person and a bus ticket in another
                  person’s name in his possession when arrested,
                  as such evidence was improper bad acts
                  evidence?

3  The record reflects that on January 24, 2019, this court denied appellant’s
application for a third extension of time to file a brief as moot, as appellant
filed a timely brief on January 23, 2019. (Per curiam order, 1/24/19.)

J. S17045/19



             II.    Did the trial court err in admitting the expert
                    testimony     of   Detective    McGinnis   over
                    [a]ppellant’s relevance objection?

             III.   Did the trial court err in admitting the expert
                    testimony     of   Detective    McGinnis     over
                    [a]ppellant’s objection that the unfair prejudice
                    arising from Detective McGinnis’s expert opinion
                    was outweighed by its probative value?

Appellant’s brief at 4.

      All three of appellant’s claims on appeal concern the admissibility of

evidence. “[T]he admission of evidence is within the sound discretion of the

trial court and will be reversed only upon a showing that the trial court clearly

abused its discretion.” Commonwealth v. Fransen, 42 A.3d 1100, 1106

(Pa.Super. 2012) (citation omitted), appeal denied, 76 A.3d 538 (Pa. 2013).

“An abuse of discretion is not merely an error of judgment; rather discretion

is abused when the law is overridden or misapplied, or the judgment exercised

is manifestly unreasonable, or the result of partiality, prejudice, bias, or ill will,

as shown by the evidence or the record.” Commonwealth v. Antidormi, 84

A.3d 736, 745 (Pa.Super. 2014) (citation omitted), appeal denied, 95 A.3d

275 (Pa. 2014).

      Appellant first argues that the trial court abused its discretion in

permitting the Commonwealth to introduce evidence that he possessed

identification and a bus pass in another person’s name on the date he was

arrested trying to flee to Los Angeles, California. (Appellant’s brief at 17.)

Appellant avers that “this evidence was improper bad acts evidence and [its]


                                        -3-
J. S17045/19

admission had a prejudicial value which unfairly outweighed its probative

value.” (Id.)

     Prior to any discussion of the merits of appellant’s claim, we must first

determine whether the record is sufficiently complete to enable our review.

Here, appellant contends that this issue was preserved during a pretrial

hearing but acknowledges that said hearing was never transcribed.        (See

appellant’s brief at 17.) We have stated “[w]hen the appellant . . . fails to

conform to the requirements of [Pa.R.A.P.] 1911 [relating to transcript

requests], any claims that cannot be resolved in the absence of the necessary

transcript or transcripts must be deemed waived for the purpose of appellate

review.”   Commonwealth v. Preston, 904 A.2d 1, 7 (Pa.Super. 2006)

(citation omitted), appeal denied, 916 A.2d 632 (Pa. 2007). Furthermore,

it is the appellant’s responsibility to make certain that the certified record

contains all items necessary to ensure that this court is able to review his

claims. See Commonwealth v. B.D.G., 959 A.2d 362, 372 (Pa.Super. 2008)

(en banc). This court has stated:

            It is black letter law in this jurisdiction that an
            appellate court cannot consider anything which is not
            part of the record in the case. It is also well-settled
            in this jurisdiction that it is Appellant’s responsibility
            to supply this Court with a complete record for
            purposes of review. A failure by appellant to insure
            that the original record certified for appeal contains
            sufficient information to conduct a proper review
            constitutes waiver of the issue sought to be examined.




                                      -4-

Commonwealth v. Martz, 926 A.2d 514, 524–525 (Pa.Super. 2007)

(citations and internal quotation marks omitted), appeal denied, 940 A.2d

363 (Pa. 2008). Based on the foregoing, we find that appellant has waived

his first issue.

      Appellant’s remaining claims challenge the admissibility of the testimony

of Chester County Detective Lieutenant Mike McGinnis (“Detective McGinnis”),

who testified as an expert in the field of cellular telephone data analysis 4 and

evaluated appellant’s cell phone usage on the date the victim’s residence was

burglarized. (See notes of testimony, 1/31/17 at 93-95, 102-115.)

      Expert testimony is governed by Pennsylvania Rule of Evidence 702,

which provides as follows:

             A witness who is qualified as an expert by knowledge,
             skill, experience, training, or education may testify in
             the form of an opinion or otherwise if:

             (a)   the expert’s scientific, technical, or other
                   specialized knowledge is beyond that
                   possessed by the average layperson;

             (b)   the expert’s scientific, technical, or other
                   specialized knowledge will help the trier of
                   fact to understand the evidence or to
                   determine a fact in issue; and

             (c)   the expert’s methodology is generally
                   accepted in the relevant field.


4 Historical cell-site analysis has been defined as “the process of analyzing
records maintained by cellular service companies to make a general
geographic determination of what tower(s) and/or sector(s) a phone used to
connect to a provider’s network.” Commonwealth v. Nevels, 203 A.3d 229,
241 (Pa.Super. 2019).


                                      -5-
J. S17045/19

Pa.R.E. 702(a)-(c).

        “[T]he proponent of expert scientific evidence bears the burden of

establishing all of the elements for its admission under [Rule] 702, which

includes showing that the Frye[5] rule is satisfied.”      Commonwealth v.

Freeman, 128 A.3d 1231, 1246 (Pa.Super. 2015) (citation omitted).           The

Frye rule, also known as the Fyre “general acceptance test,” provides that

“novel scientific evidence is admissible if the methodology that underlies the

evidence has general acceptance in the relevant scientific community.”

Commonwealth v. Walker, 92 A.3d 766, 789 (Pa. 2014) (citation and

internal quotation marks omitted); see also Freeman, 128 A.3d at 1246.

        Although not entirely clear from his “Statement of Question Involved,”

appellant’s argument with regard to this matter appears to be three-fold.



A. Expert’s Specialized Knowledge under Rule 702(a)

        The crux of appellant’s first claim is that Detective McGinnis failed to

render his expert opinion on the approximate range of the cell tower utilized

by appellant’s cell phone on the day of the burglary with a reasonable degree

of certainty. Specifically, appellant contends that Detective McGinnis’ expert

testimony was “based on averages and assumptions rather than specific facts

regarding the cell towers at issue,” and “did not comply with the requirements

set forth in [Rule 702(a)].” (Appellant’s brief at 18, 24.) We disagree.


5   Frye v. United States, 293 F. 1013 (D.C.Cir. 1923).


                                      -6-
J. S17045/19

      As noted, Rule 702(a) requires that “the expert’s scientific, technical, or

other specialized knowledge is beyond that possessed by the average

layperson[.]” Pa.R.E. 702(a) (emphasis added). “While an expert need not

use ‘magic words,’ the foundation of [his] opinion must still be sturdy . . . the

expert must base the substance of [his] opinion on a reasonable degree of

certainty instead of mere speculation.” Commonwealth v. Gonzalez, 109

A.3d 711, 727 (Pa.Super. 2015) (citation omitted), appeal denied, 125 A.3d

1198 (Pa. 2015).

      In the instant matter, our review of the record establishes that

Detective McGinnis’ testimony met the standard for admissibility set forth in

Rule 702(a) and Gonzalez. At trial, Detective McGinnis testified as an expert

in the field of cellular telephone data analysis, noting to a reasonable degree

of professional certainty the approximate range of the cell tower utilized by

appellant’s cell phone on the day of the burglary, as well as the location of the

cell phone within those coverage areas.      (Notes of testimony, 1/31/17 at

94-95, 130.)   Specifically, Detective McGinnis testified that the cell phone

found on appellant’s person at the time of his arrest utilized a cell tower

located on Lenape Road in Pocopson Township, Chester County at 10:43 a.m.,

10:47 a.m., and 10:48 a.m. on the morning of the burglary. (Id. at 102.)

Detective   McGinnis   further   noted   that   the   victim’s   residence   was

approximately one-third of a mile away from this tower. (Id. at 107-108.)

Detective McGinnis opined that the industry standard for such a tower is a



                                      -7-
J. S17045/19

range of between one and one-half to two miles and that he was able to

determine that the aforementioned calls were made on the western end of the

county. (Id. at 113, 116 and 118.)

      In reaching these conclusions, Detective McGinnis was questioned at

great length with respect to maps he created during his data analysis, which

reflected the operational range of cell phone towers near the victim’s

residence.   (Id. at 99-119, 129-130.)       Detective McGinnis noted that,

“[g]enerally speaking, there is a radius for each of the towers. The analysis

shows that when you make a call, we receive that tower location, that device

is within that particular radius.” (Id. at 113.) Detective McGinnis averred

that he estimated the range of each tower in question based on the location

of nearby towers and an expected amount of overlap in the coverage areas.

(Id. at 141-142.) In determining the location of appellant’s cell phone on the

day, Detective McGinnis reviewed the tower location and coverage area

utilized by appellant’s cell phone. Detective McGinnis acknowledged that in

estimating the coverage range of a tower, various factors are taken into

consideration, including topography of the area, signal capacity, and weather.

(Id. at 135-138, 143.)      As noted, Detective McGinnis opined, within a

reasonable degree of professional certainty, that based on the approximate

range of the cell tower utilized by appellant’s cell phone on the morning of the

burglary, appellant’s cell phone was in close proximity to the victim’s

residence. (Id. at 130.) Contrary to appellant’s contention, we do not find



                                     -8-
J. S17045/19

that Detective McGinnis’ conclusions were of a nature that they would be

“possessed by the average layperson[.]” See Pa.R.E. 702(a). Accordingly,

the trial court did not abuse its discretion in permitting Detective McGinnis’

expert testimony to be offered into evidence.



B. Expert’s Methodology under Rule 702(c) and Fyre

        Appellant next posits that the Commonwealth did not sustain its burden

of establishing that the methodology employed by Detective McGinnis was

generally accepted in his field, pursuant to Frye. Specifically, appellant avers

that:

              there was absolutely no evidence, as required by
              [Rule]    702(c)[,]   that   [Detective]    McGinnis’s
              methodology of eyeballing the towers and figuring the
              network isn’t going to over-cover the area is generally
              accepted within the relevant field to determine the
              signal strength and range of a cell tower.

Appellant’s brief at 24. We disagree.

        As noted, Rule 702(c) incorporates the Frye standard. Freeman, 128

A.3d at 1246; see also Grady v. Frito–Lay, 839 A.2d 1038, 1042 (Pa. 2003)

(noting that the Frye test “is part of Rule 702.”). “However, the Frye analysis

is not triggered every time science enters the courtroom; it only applies when

an expert seeks to introduce novel scientific evidence.” Commonwealth v.

Dengler, 843 A.2d 1241, 1243 (Pa.Super. 2004), affirmed, 890 A.2d 372

(Pa. 2005).     “As such, the trial court need only analyze this element of

Rule 702 when Frye is implicated, that is, when novel scientific evidence


                                       -9-
J. S17045/19

is at issue.”   Commonwealth v. Powell, 171 A.3d 294, 308 (Pa.Super.

2017) (emphasis added), appeal denied, 183 A.3d 975 (Pa. 2018).

      In Commonwealth v. Nevels, 203 A.3d 229 (Pa.Super. 2019), a panel

of this court recently recognized that scientific evidence concerning historical

cell-site analysis was not novel, and thus its admissibility was not subject to

requirements of the Frye general acceptance test. Id. at 239. The Nevels

court stated:

            Upon review, we conclude that there exists no
            legitimate dispute regarding the reliability of historical
            cell-site analysis, and we therefore construe Frye
            narrowly so as not to impede [the] admissibility of the
            Commonwealth’s historical cell-site analysis evidence.
            Accordingly, we hold that scientific evidence
            concerning historical cell-site analysis is not
            novel, and its admissibility is not subject to the
            requirements of Frye.

Id. at 241 (citation and internal quotation marks omitted; emphasis added).

      Based on the foregoing, we conclude that Detective McGinnis’ testimony

in this matter was not based on novel scientific evidence, and thus, the

Commonwealth bore no burden of establishing that the methodology

employed by Detective McGinnis satisfied the Frye “general acceptance” test.

Accordingly, the trial court did not abuse its discretion in admitting

Detective McGinnis’ expert testimony into evidence.

J. S17045/19

C. Relevance and Probative Value versus Prejudicial Impact

      In his final claim, appellant contends that the trial court abused its

discretion by admitting Detective McGinnis’ expert testimony on the range of

the cell tower utilized by appellant’s cell phone because it was irrelevant and

that its prejudicial impact outweighed its probative value. (Appellant’s brief

at 18, 24-25, 27.) Specifically, appellant maintains that,

            [t]he danger of unfair prejudice to [a]ppellant far
            outweighed the probative value of this testimony
            considering that the range of the specific tower was
            not known.       This was an industry standard, an
            average of the ranges of Chester County towers. The
            range and the signal strength of the specific towers
            could have been measured, but were not. There were
            scientific calculations and findings specific to this case
            that could have been made, but they were not.
            Allowing an expert opinion placing the cellular device
            in close proximity to the burglary based on the
            average of a Chester County cell tower was unfairly
            prejudicial and misleading.

Id. at 28. We disagree.

      “Evidence is relevant if it logically tends to establish a material fact in

the case, tends to make a fact at issue more or less probable, or supports a

reasonable inference or presumption regarding the existence of a material

fact.” Antidormi, 84 A.3d at 750 (citation omitted); see also Pa.R.E. 401.

Pursuant to Pennsylvania Rule of Evidence 403, “[t]he court may exclude

relevant evidence if its probative value is outweighed by a danger of one or

more of the following: unfair prejudice, confusing the issues, misleading the

jury, undue delay, wasting time, or needlessly presenting cumulative



                                     - 11 -
J. S17045/19

evidence.” Pa.R.E. 403. The term “unfair prejudice” is defined as “a tendency

to suggest decision on an improper basis or to divert the jury’s attention away

from its duty of weighing the evidence impartially.” Id. Comment.

              [I]n cases involving the admission of expert testimony
              . . . the admission of expert testimony is a matter left
              largely to the discretion of the trial court, and its
              rulings thereon will not be reversed absent an abuse
              of discretion. An expert’s testimony is admissible
              when it is based on facts of record and will not cause
              confusion or prejudice.

Commonwealth v. Huggins, 68 A.3d 962, 966 (Pa.Super. 2013) (citation

omitted), appeal denied, 80 A.3d 775 (2013).

      Here,     the   trial   court   found     that   the   probative   value    of

Detective McGinnis’ expert opinion on the cellular telephone data collected in

this case outweighed its prejudicial impact.           Specifically, the trial court

reasoned that Detective McGinnis’ expert testimony “aided the jury in their

determination of the issues [and] . . . did not confuse or mislead them in any[]

way.” (Trial court opinion, 9/10/18 at 5.) Upon review, we discern no abuse

of discretion on the part of the trial court in reaching this conclusion.

Detective McGinnis’ testimony that the cellular telephone data he analyzed

demonstrated that appellant’s cell phone was in close proximity to the victim’s

residence the morning of the burglary was both relevant and highly probative

in establishing appellant’s whereabouts, and was not overly prejudicial.

Accordingly, we find that the trial court did not abuse its discretion in




                                       - 12 -
J. S17045/19

overruling appellant’s objection to Detective McGinnis’ expert testimony on

these grounds.

     For all the foregoing reasons, we affirm the July 5, 2017 judgment of

sentence.

     Judgment of sentence affirmed.
