18 HANISEE, Judge.
                                                                                          


 1   {1}   Defendant Gabriel Montoya appeals from his convictions following a jury

 2 trial for armed robbery, conspiracy to commit armed robbery, aggravated burglary,

 3 and conspiracy to commit aggravated burglary. Defendant was sentenced to

 4 twenty-six years of imprisonment, which includes two years of mandatory firearm

 5 enhancements of his sentences for armed robbery and aggravated burglary.

 6 Defendant advances the following arguments on appeal: (1) his right to be free

 7 from double jeopardy was violated by both of his conspiracy convictions as well as

 8 the firearm enhancements to his sentences for armed robbery and aggravated

 9 burglary; (2) the district court erred by not allowing a second substitution of

10 defense counsel shortly before trial; (3) the district court erred by not granting

11 Defendant’s request for a continuance of the jury trial; (4) the district court erred

12 by excluding the testimony of Defendant’s father, Steven Montoya; (5)

13 Defendant’s right to effective assistance of counsel was violated; (6) the district

14 court erred by denying Defendant’s requested jury instruction concerning the

15 unreliability of accomplice testimony; (7) the accomplice testimony offered by the

16 State against Defendant was insufficient to sustain his convictions; (8) the district

17 court erred by denying Defendant’s request for a mistrial because of an alleged

18 mischaracterization by the State in its rebuttal closing argument; and (9) the district

19 court’s cumulative errors require reversal because Defendant was deprived of his

20 right to a fair trial.

 1   {2}   We agree that the State did not present evidence of separate conspiracies.

 2 Accordingly, we remand this case to the district court with instructions that it

 3 vacate one of Defendant’s conspiracy convictions and resentence Defendant

 4 accordingly. For the reasons set forth herein, we are unpersuaded by Defendant’s

 5 remaining arguments and otherwise affirm.

 6 BACKGROUND

 7   {3}   Defendant, Leroy Lucero, and Harry Williams conspired to burglarize Lisa

 8 and Tristan Hawkins’ home, with which Defendant was familiar and believed

 9 contained firearms, as well as a safe, cash, and tools. Dressed as a pizza delivery

10 person, Mr. Williams knocked on the Hawkins’ front door. When Ms. Hawkins

11 answered the door and told Mr. Williams that she had not ordered pizza, Mr.

12 Williams asked her to help him verify the address he claimed to be his intended

13 destination. As Ms. Hawkins stepped outside to do so, Mr. Williams displayed a

14 firearm and ordered her to go back inside. Defendant, Mr. Williams and Mr.

15 Lucero then entered the house, ordered Ms. Hawkins to the floor, tied her up and

16 covered her head with a jacket so she could not see.

17   {4}   When she denied having the keys to the safe and that there was cash in her

18 house, the coconspirators pistol-whipped Ms. Hawkins. They then located and

19 stole thirty firearms, Ms. Hawkins’ phone, cash, and debit cards, along with




                                            3
      
                                                                                         


 1 various tools and videos. Both Mr. Lucero and Mr. Williams were presented by the

 2 State as witnesses during Defendant’s trial.

 3   {5}   Because this is a non-precedential opinion drafted to inform the parties of

 4 our reasoning, we omit further factual discussion at this time and discuss only

 5 those additional facts that are necessary to our analysis.

 6 DISCUSSION

 7 I.      Double Jeopardy

 8   {6}   We review Defendant’s double jeopardy arguments de novo as a matter of

 9 law. State v. Gallegos, 2011-NMSC-027, ¶ 51, 149 N.M. 704, 254 P.3d 655. When

10 “factual issues are intertwined with the double jeopardy analysis, we review the

11 trial court’s fact determinations under a deferential substantial evidence standard of

12 review.” Id. (internal quotation marks and citation omitted). “The defense of

13 double jeopardy may not be waived and may be raised by the accused at any stage

14 of a criminal prosecution, either before or after judgment.” NMSA 1978, § 30-1-10

15 (1963).

16 A.      One of Defendant’s Conspiracy Convictions Must Be Vacated as a
17         Violation of Defendant’s Right to Be Free From Double Jeopardy

18   {7}   The jury convicted Defendant of conspiracy to commit armed robbery and

19 conspiracy to commit aggravated burglary, among other crimes. As Defendant

20 argues and the State concedes, under Gallegos, the State did not present evidence

21 of separate conspiratorial agreements as to each offense. See 2011-NMSC-027, ¶¶
                                              4
      
                                                                                           


 1 42, 55, 56 (holding that there exists a “rebuttable presumption that multiple crimes

 2 are the object of only one, overarching conspiratorial agreement” and that the

 3 “presumption of singularity may [only] be overcome by [evidence] demonstrating

 4 the existence of more than one conspiracy”). Given that the evidence presented by

 5 the State at trial indicated that both conspiracies were jointly planned, and the

 6 ensuing acts of armed robbery and aggravated burglary were jointly carried out by

 7 those conspirators, including Defendant, we agree.

 8   {8}   Gallegos further instructs that punishment should be imposed on the “single

 9 remaining conspiracy at the level of the highest crime conspired to be

10 committed[.]” Id. ¶ 64 (internal quotation marks and citation omitted). Aggravated

11 burglary and armed robbery are both second degree felonies, so either one of

12 Defendant’s conspiracy convictions may be vacated. We therefore remand this

13 case to the district court to vacate one of Defendant’s conspiracy convictions and

14 to resentence Defendant consistent with this determination.

     B.    The Firearm Sentencing Enhancements Do Not Violate Defendant’s
           Right to Remain Free of Double Jeopardy

15   {9}   Defendant argues that separate, one-year enhancements of his convictions

16 for armed robbery and aggravated burglary, imposed pursuant to NMSA 1978,

17 Section 31-18-16(A) (1993), the firearm enhancement statute, violate double

18 jeopardy because the same conduct, Defendant’s use of a firearm, violates the

19 statutes criminalizing armed robbery and aggravated burglary and serves as the
                                            5
      
                                                                                             


 1 factual predicate for sentencing enhancement. However, as the State points out in

 2 its answer brief, this same challenge to the firearm enhancement statute has been

 3 resolved recently by our Supreme Court in State v. Baroz, 2017-NMSC-030, ¶ 20,

 4 23, 404 P.3d 769, which evaluated the applicability of double jeopardy to separate

 5 firearm enhancements for two convictions of aggravated assault with a deadly

 6 weapon stemming from the defendant’s unitary act of firing a gun. Baroz held that

 7 “the Legislature intended to authorize greater punishment for noncapital felonies

 8 committed with a firearm[,]” and as such individual firearm enhancements do “not

 9 run afoul of double jeopardy.” Id. ¶ 27. We therefore affirm the district court’s

10 imposition of firearm enhancements to Defendant’s sentences for armed robbery

11 and aggravated burglary.

12 II.      The District Court Did Not Abuse Its Discretion by Denying a Second
13          Substitution of Defense Counsel

14   {10}   Defendant contends that the district court’s refusal to allow substitution of

15 defense counsel shortly before trial deprived Defendant of his constitutional right

16 to conflict-free counsel in light of Defendant’s attorney’s (defense counsel) poor

17 health in the months prior to trial. The State counters that both defense counsel and

18 the attorney willing to substitute for defense counsel agreed that a substitution was

19 not necessary, and that the district court did not abuse its discretion in denying the

20 substitution. The State also argues that defense counsel’s health does not bear the

21 capacity to constitute a “conflict” such that substitution was required. We affirm on
                                              6
      
                                                                                              


 1 the basis that the district court did not abuse its discretion in denying the

 2 substitution requested by Defendant.

 3 A.       Standard of Review

 4   {11}   We review the district court’s decision as to whether to appoint substitute

 5 counsel for abuse of discretion. State v. Lucero, 1986-NMCA-085, ¶ 21, 104 N.M.

 6 587, 725 P.2d 266. Although an indigent defendant has the right to appointed

 7 counsel, that right does not include the right to choose his attorney. Id. “In order to

 8 dismiss the appointed counsel, a defendant must come forward and make a

 9 showing that failure to appoint substitute counsel will result in ineffective

10 representation or prejudice to the defense.” Id.

11 B.       Analysis

12   {12}   In March 2014, approximately seven months before trial, the district court

13 permitted the withdrawal of two private attorneys based upon an unspecified actual

14 conflict of interest. The district court then directed that the Law Offices of the

15 Public Defender represent Defendant, and the following month defense counsel

16 entered his first and only appearance for Defendant. In October 2014, and despite

17 defense counsel not having sought to withdraw, a separate public defender contract

18 attorney, Christopher Knight, entered his appearance for Defendant.

19   {13}   During a pretrial conference attended by Defendant, defense counsel, and

20 Mr. Knight, defense counsel informed the district court that the public defender’s


                                              7
      
                                                                                            


 1 office had notified him that he would no longer represent Defendant, possibly

 2 because “[Defendant’s] father had [spoken with the public defender’s office] and

 3 made a convincing case for some problem that he had.” Regarding his illness,

 4 defense counsel stated that he had been diagnosed with meningitis in July 2014,

 5 which had affected him “significantly” from July through September of that year.

 6 Defense counsel stated, “I don’t like [to] try to get off cases . . . [u]nless there is a

 7 real conflict that I can’t resolve with a client.” Defense counsel did not move to

 8 withdraw. At no time did defense counsel claim an inability to prepare for or

 9 represent Defendant in the November trial. Also during the conference, Mr. Knight

10 acknowledged that he was unprepared to try the case in less than a month, that

11 defense counsel’s “file [was] extremely well prepared” and “voluminous[,]” and

12 that Mr. Knight saw no “major conflict or any other reason to go ahead and

13 suddenly do a reassignment of an attorney.”

14   {14}   The district court then asked Defendant if he had “any particular complaints”

15 with defense counsel’s representation. Defendant stated three concerns: (1) defense

16 counsel had not yet filed another motion to review conditions of release; (2)

17 Defendant heard from defense counsel’s other clients that they were not satisfied

18 and defense counsel’s contact with them had been “very minimal”; and (3) on one

19 occasion defense counsel went to the Metropolitan Detention Center to meet with

20 Defendant but had forgotten the file for one of Defendant’s other cases. Defendant


                                               8
      
                                                                                            


 1 insisted that he was willing to remain in custody for another three or four months if

 2 necessary so Mr. Knight would have time to prepare the case for trial.

 3   {15}   Having noted earlier in the conference that that under Rule 5-107(B)

 4 NMRA, district courts, and not defendants or the public defender’s office, decide

 5 whether an attorney on a given case may withdraw, the district court denied

 6 Defendant’s request for a second substitute counsel and ordered defense counsel to

 7 continue to represent Defendant because there was no “legal basis for having

 8 [defense counsel] withdraw.” The district court reasoned that defense counsel did

 9 not move to withdraw, and that while usually substitution of counsel is “liberally

10 granted[,]” by then the case had been pending over two years, within which there

11 had been multiple continued trial settings.

12   {16}   We hold that the district court did not abuse its discretion in refusing to

13 permit substitution of defense counsel. Defendant’s stated reasons for why he

14 wanted a new attorney in no way conveyed that defense counsel’s continued

15 representation would result in ineffective assistance or prejudice to Defendant, or

16 touched upon the subject of any actual conflict regarding defense counsel’s

17 ongoing representation of Defendant. See State v. Bell, 1977-NMSC-013, ¶ 68, 90

18 N.M. 134, 560 P.2d 925 (holding no tenable showing of abuse of discretion when

19 no claim of inadequate representation or prejudice to defense was made). The

20 ongoing circumstance of Defendant’s pretrial incarceration, along with defense


                                             9
      
                                                                                           


 1 counsel’s representation of other defendants and his isolated lapse in forgetting to

 2 bring a file on one occasion when visiting Defendant in custody, are largely

 3 irrelevant to the inquiry of whether the circumstances dictated a ruling, based on

 4 conflict, ineffectiveness of representation, or prejudice, outside the range of

 5 discretion afforded the district court. Combined with the district court’s

 6 consideration of the long pendency of this case and the multiple previous trial

 7 settings, we cannot conclude the district court abused its discretion in denying a

 8 second substitution of defense counsel.

 9   {17}   Given Defendant’s failure to make specific record citations regarding

10 precisely how defense counsel’s illness affected his representation of Defendant,

11 see State v. Lopez, 2018-NMCA-002, ¶ 26, 410 P.3d 226 (stating that in the

12 absence of citation to specific facts in the record, we will not search for them to

13 support generalized arguments), we only briefly address Defendant’s argument that

14 defense counsel’s health issues undermined his loyalty to Defendant, resulting in

15 an actual conflict of interest for which prejudice to Defendant is presumed, and

16 that the conflict prevented defense counsel from pursuing a viable defense strategy.

17 Defendant relies on State v. Martinez, 2001-NMCA-059, 130 N.M. 744, 31 P.3d

18 1018, and State v. Santillanes, 1990-NMCA-035, 109 N.M. 781, 790 P.2d 1062,

19 both of which are distinguishable from this case. The conflict of interest in

20 Martinez was that the defense attorney had been implicated in the murder for


                                             10
      
                                                                                         


 1 which he was defending his client, 2001-NMCA-059, ¶ 27, while the conflict of

 2 interest in Santillanes was that the defense attorney had jointly represented two

 3 brothers on the same case, and “[b]y attempting to establish a defense for co-

 4 defendant, trial counsel was forced to abandon strategy that could have been used

 5 to exonerate defendant.” 1990-NMCA-035, ¶ 10. Neither of these extreme

 6 circumstances exists in this case, nor has Defendant provided a basis from which

 7 the presumption of prejudice can arise based upon an actual conflict. We affirm the

 8 district court’s denial of Defendant’s motion to substitute.

 9 III.     Defendant Did Not Move to Continue the Jury Trial and Therefore Did
10          Not Preserve His Challenge That the District Court Committed
11          Reversible Error by Not Continuing Defendant’s Trial

12   {18}   Defendant argues that the district court erred in not continuing his trial

13 because during a pretrial hearing defense counsel “appeared wholly unprepared

14 and unaware of the substance of witness testimony he potentially intended to rely

15 upon.” He further contends that the district court erred by not clarifying whether

16 Defendant sought a continuance. The State counters that Defendant did not seek a

17 continuance and that this claim of error was not preserved.

18   {19}   Our review of the record confirms that Defendant did not request a

19 continuance prior to trial. Although defense counsel, during a pretrial hearing,

20 twice referenced the possibility of a continuance based on unrelated issues

21 regarding trial witnesses, on neither occasion did he actually request one. First,


                                             11
      
                                                                                              


 1 regarding the fact that the State had not interviewed several defense witnesses,

 2 defense counsel stated, “I can ask for a continuance in the case to complete that

 3 part of the investigation, is one possible remedy to the situation. But the other

 4 possible way we could approach it would be to attempt to at least get some of the

 5 most salient of . . . these witnesses available to the State prior to the beginning of

 6 the defendant’s case and to not mention them in the opening.” Second, when the

 7 State notified defense counsel that it would not call the case agent to testify,

 8 defense counsel said, “[I]t appears that if we’re not going to continue the trial on

 9 the basis of this witness’s unavailability . . . then our choice, really, is to move to

10 suppress him[.]” The district court then pointed out, “Nobody has asked me to

11 continue [the trial]; I’m just mentioning that. So you’re going to move to

12 suppress?” (Emphasis added.) Defense counsel responded, “Yes, [y]our Honor.”

13   {20}   Thus, since Defendant did not affirmatively seek a continuance of the trial

14 setting, the issue is unpreserved and we decline to address it further. See Rule 12-

15 321(A) NMRA (“To preserve an issue for review, it must appear that a ruling or

16 decision by the trial court was fairly invoked.”). Nor is there any duty on the part

17 of the district court to sua sponte continue the trial, and we reject Defendant’s

18 contention that the district court should have done so or inquired in greater detail

19 as to Defendant’s position with regard to a trial continuance. See State v. Montoya,

20 1993-NMCA-097, ¶ 19, 116 N.M. 297, 861 P.2d 978 (declining to review the


                                             12
      
                                                                                           


 1 district court’s denial of a motion for continuance because the trial record did not

 2 show that such a motion was made to the district court and stating “[t]here is no

 3 duty upon the trial court to order a continuance when none has been requested.”).

 4 IV.      The District Court Did Not Abuse Its Discretion by Excluding Steven
 5          Montoya’s Testimony

 6   {21}   Defendant contends that the district court abused its discretion by excluding

 7 testimony from Defendant’s father, Steven Montoya, who Defendant did not

 8 timely disclose as a defense witness and whose proposed testimony the district

 9 court determined to be inadmissible. Defendant argues that Mr. Montoya should

10 have been permitted to testify regarding his knowledge of Mr. Hawkins, whose

11 home Defendant and his coconspirators burglarized and who testified that he saw

12 Defendant and Mr. Lucero together at a gas station the morning of the robbery.

13 The State responds that Defendant twice attempted to provide proffers for Mr.

14 Montoya’s testimony during trial, and that neither proffer included anything

15 admissible or related to Mr. Hawkins’ motive to lie. Moreover, defense counsel

16 could have, but chose not to, cross-examine Mr. Hawkins about his motive to lie

17 rather than hope to call Mr. Montoya to testify later, so any error was harmless.

18 A.       Standard of Review

19   {22}   Admissibility of the testimony at issue is governed by Rules of Evidence,

20 11-403, 11-404, and 11-608 NMRA, a district court’s application of which is

21 reviewed for an abuse of discretion. See State v. Torres, 2018-NMSC-013, ¶ 58,
                                              13
      
                                                                                             


 1 413 P.3d 467 (stating admissibility of evidence under Rule 11-608 “is left to the

 2 sound discretion of the trial court”) (internal quotation marks and citation omitted);

 3 State v. Sena, 2008-NMSC-053, ¶ 12, 144 N.M. 821, 192 P.3d 1198 (stating same

 4 regarding Rule 11-404(B); State v. Sarracino, 1998-NMSC-022, ¶ 20, 125 N.M.

 5 511, 964 P.2d 72 (“We review the admission of evidence under an abuse of

 6 discretion standard and will not reverse in the absence of a clear abuse.”). A court

 7 abuses its discretion when it makes an evidentiary ruling that “is clearly against the

 8 logic and effect of the facts and circumstances of the case” and “clearly untenable

 9 or not justified by reason.” State v. Samora, 2016-NMSC-031, ¶ 37, 387 P.3d 230

10 (internal quotation marks and citation omitted).

11   {23}   “All relevant evidence is generally admissible, unless otherwise provided by

12 law[.]” State v. Balderama, 2004-NMSC-008, ¶ 23, 135 N.M. 329, 88 P.3d 845.

13 “Evidence that reflects on a witness[’s] credibility is relevant.” State v. Johnson,

14 2010-NMSC-016, ¶ 41, 148 N.M. 50, 229 P.3d 523. “Any doubt whether the

15 evidence is relevant should be resolved in favor of admissibility.” Balderama,

16 2004-NMSC-008, ¶ 23. Rule 11-403 instructs that evidence that is otherwise

17 admissible may be excluded if its probative value is substantially outweighed by

18 danger of unfair prejudice, confusion of issues, waste of time, delay, or

19 presentation of cumulative evidence. Rule 11-404(A)(1) prescribes that

20 “[e]vidence of a person’s character or character trait is not admissible to prove that


                                             14
      
                                                                                            


 1 on a particular occasion the person acted in accordance with the character or trait.”

 2 Rule 11-404(A)(3) states that “[e]vidence of a witness’s character may be admitted

 3 under Rules 11-607, 11-608, and 11-609 NMRA.” Rule 11-607 instructs that

 4 “[a]ny party, including the party that called the witness, may attack the witness’s

 5 credibility.” Lastly, pursuant to Rule 11-608(B)(1), cross-examination about

 6 specific instances of conduct probative of the witness’s character for truthfulness is

 7 generally admissible, although extrinsic evidence is not admissible to prove such

 8 conduct.

 9 B.       Analysis

10   {24}   Pointing to very few specifics during trial or in his briefing on appeal,

11 Defendant argued at trial that Mr. Montoya would have testified that on one

12 occasion he observed Mr. Hawkins act “physically aggressive toward” Defendant

13 at Defendant’s grandfather’s home, which defense counsel argued was relevant to

14 Mr. Hawkins’ “motivation to have [Defendant] charged and convicted in this case”

15 and amounted to a “potential grudge against [Defendant].” In his brief in chief,

16 Defendant argues that Mr. Montoya wished to testify regarding Mr. Hawkins’

17 “vindictiveness toward [Defendant,]” which related to his bias and motivation to

18 lie, and in his reply brief added Mr. Montoya would have testified that Mr.

19 Hawkins believed Defendant to be having an affair with Ms. Hawkins.




                                             15
      
                                                                                             


 1   {25}          Based upon Rules 11-404(B), 11-405, and 11-608, the State sought

 2 exclusion of Mr. Montoya’s testimony, which the State characterized as evidence

 3 of a “grudge” that served as the basis for Mr. Hawkins’ effort to have Defendant

 4 arrested. The State argued that based on Defendant’s proffer, Mr. Montoya’s

 5 testimony was irrelevant because it did not make “any matter at issue more or

 6 less . . . probative or probable.” The State also argued that Mr. Montoya was

 7 disclosed late, and that during the pretrial interview, Mr. Montoya stated he did not

 8 have anything relevant to say and denied that there was anything specific about

 9 which he would testify.

10   {26}          The district court ultimately excluded Mr. Montoya’s testimony, not on

11 grounds of untimely disclosure as Defendant suggests, but because Mr. Montoya’s

12 testimony was irrelevant under Rule 11-401 as extrinsic evidence concerning a

13 collateral matter, inadmissible under Rule 11-403 because it lacked probative

14 value, or if it had any probative value, it was minimal and “substantially

15 outweighed by confusion of the issues[,]” and thus inadmissible under Rule 11-

16 404(A).1



                                                                 
                   1
             The district court also observed that it was defense counsel, and not the
     State, that elicited the only “direct testimony from Mr. Hawkins that [Defendant]
     did anything” when Mr. Hawkins testified on cross-examination that he “thought
     [of Defendant] immediately” as the person who could have committed the robbery
     of his home.
      

                                                                    16
      
                                                                                              


 1   {27}   We conclude that the district court acted within its discretion when it

 2 disallowed testimony from Mr. Montoya. Testimony that Mr. Hawkins acted

 3 aggressively toward Defendant on a single occasion was minimally relevant

 4 because the testimony was not probative of Mr. Hawkins’ grudge, his motive to lie,

 5 his credibility, or his character for truthfulness. Further, we agree with the district

 6 court that the de minimis probative value of this testimony was substantially

 7 outweighed by the confusion of the issues it would cause and was therefore

 8 inadmissible under Rule 11-403.

 9   {28}   We likewise conclude that Mr. Montoya’s testimony was inadmissible under

10 Rule 11-608(B). Although the district court did not refer to Rule 11-608(B) in its

11 ruling, we may affirm the district court if it is right for any reason, and we

12 therefore briefly evaluate the exclusion under Rule 11-608(B). See State v.

13 Patterson, 2017-NMCA-045, ¶ 15, 395 P.3d 543 (analyzing admissibility of

14 evidence under Rule 11-403 as alternative basis for its holding under right for any

15 reason doctrine); see also Gallegos, 2007-NMSC-007, ¶ 26 (analyzing

16 admissibility of evidence under theory not argued below pursuant to right for any

17 reason doctrine as long as doing so is fair to appellant). Mr. Montoya’s proposed

18 testimony about Mr. Hawkins acting aggressively toward Defendant on a prior

19 occasion constitutes extrinsic evidence of a specific instance of Mr. Hawkins’

20 conduct offered to attack Mr. Hawkins’ character for truthfulness, which Rule 11-


                                             17
      
                                                                                             


 1 608(B) expressly prohibits. See id. (“Except for a criminal conviction under Rule

 2 11-609 . . . extrinsic evidence is not admissible to prove specific instances of a

 3 witness’s conduct in order to attack or support the witness’s character for

 4 truthfulness.”) The district court therefore did not abuse its discretion in excluding

 5 Mr. Montoya’s testimony.

 6   {29}   Defendant contends that “[r]egardless of whether [Mr. Montoya’s testimony]

 7 was excludable under the rules of evidence . . . the New Mexico Supreme Court

 8 has specifically recognized that the rules cannot limit a defendant’s constitutional

 9 right to challenge ‘an opposing version of facts[,]’ ” quoting from State v. Johnson,

10 1997-NMSC-036, ¶ 23, 123 N.M. 640, 944 P.2d 869. Defendant’s reliance on

11 Johnson is misplaced, primarily because nothing in Mr. Montoya’s proposed

12 testimony bore the capacity to directly challenge Mr. Hawkins’ testimony or his

13 credibility, and defense counsel could have cross-examined Mr. Hawkins about

14 any bias he had against Defendant that might have affected his truthfulness. See id.

15 ¶ 23 (“A defendant’s right of confrontation—with its protection of the right to

16 cross-examine, test credibility, detect bias, and otherwise challenge an opposing

17 version of facts—is a critical limitation on the trial court’s discretion to exclude

18 evidence a defendant wishes to admit.”). Defense counsel provided no explanation

19 for his decision not to cross-examine Mr. Hawkins regarding any possible




                                             18
      
                                                                                        


 1 motivation he might harbor to have Defendant wrongly charged and wrongly

 2 convicted.

 3   {30}   Moreover, Mr. Montoya’s testimony was not, as Defendant argues, crucial

 4 to Defendant’s theory of the case, because nothing in Mr. Montoya’s testimony

 5 would have suggested that Mr. Hawkins had a motive to lie about Defendant’s

 6 involvement in the underlying crimes, and as the district court pointed out, defense

 7 counsel elicited the only direct testimony from Mr. Hawkins on that topic. Mr.

 8 Montoya’s proposed testimony regarding a prior act of aggression by Mr. Hawkins

 9 also was not significant because both of Defendant’s coconspirators testified in

10 detail about Defendant’s involvement in the crimes being considered by the jury.

11 Even if the jury somehow believed that Mr. Hawkins’ prior behavior was

12 indicative of a preexisting grudge, which then led Mr. Hawkins to lie about his

13 suspicion of Defendant’s involvement, Mr. Hawkins was not the only witness that

14 testified about Defendant’s involvement in the underlying crimes. The district

15 court’s exclusion of Mr. Montoya’s testimony did not violate Defendant’s right of

16 confrontation, and accordingly we affirm.

17 V.       Defendant Has Not Presented a Prima Facie Case of Ineffective
18          Assistance of Counsel

19   {31}   Defendant asserts that defense counsel was ineffective for four reasons: (1)

20 he failed to impeach Mr. Hawkins with a prior criminal conviction; (2) he did not

21 timely disclose Steven Montoya as a witness and did not understand the “full
                                             19
      
                                                                                            


 1 extent” of his testimony until after most of the State’s witnesses had testified; (3)

 2 he chose not to call Ms. Lucero, Mr. Lucero’s wife, to testify; and (4) defense

 3 counsel’s ill health compromised his ability to effectively represent him. The State

 4 responds that the district court’s exclusion of Steven Montoya was not solely

 5 premised on his late disclosure and that Ms. Lucero’s testimony would not have

 6 been useful to Defendant, and thus there was no ineffective assistance of counsel.

 7 We review appellate claims of ineffective assistance of counsel de novo. State v.

 8 Cordova, 2014-NMCA-081, ¶ 6, 331 P.3d 980.

 9   {32}   “The Sixth Amendment to the United States Constitution, applicable to the

10 states through the Fourteenth Amendment, guarantees defendants in criminal

11 proceedings the right to effective assistance of counsel.” Id. “Our Supreme Court

12 has expressed a preference that ineffective assistance of counsel claims be

13 adjudicated in habeas corpus proceedings, rather than on direct appeal.” Id. ¶ 7.

14 “Therefore, this Court will only remand a case for an evidentiary hearing if the

15 record on appeal supports a prima facie case of ineffective assistance of counsel.”

16 Id.

17   {33}   A prima facie case of ineffective assistance of counsel requires a defendant

18 to establish that: “(1) counsel’s performance fell below that of a reasonably

19 competent attorney; (2) no plausible, rational strategy or tactic explains counsel’s

20 conduct; and (3) counsel’s apparent failings were prejudicial to the defense.” Id. ¶


                                             20
      
                                                                                          


 1 9; see also State v. Bernal, 2006-NMSC-050, ¶ 32, 140 N.M. 644, 146 P.3d 289

 2 (“For a successful ineffective assistance of counsel claim, a defendant must first

 3 demonstrate error on the part of counsel, and then show that the error resulted in

 4 prejudice.”). To prove prejudice, a defendant “must demonstrate that counsel’s

 5 errors were so serious, such [as] a failure of the adversarial process, that such

 6 errors undermine judicial confidence in the accuracy and reliability of the

 7 outcome.” Bernal, 2006-NMSC-050, ¶ 32 (alteration, internal quotation marks, and

 8 citation omitted). If there is a “reasonable probability” that “the result of the

 9 proceeding would have been different” but for counsel’s deficient performance,

10 such a probability is “sufficient to undermine confidence in the outcome.” Lytle v.

11 Jordan, 2001-NMSC-016, ¶ 27, 130 N.M. 198, 22 P.3d 666 (quoting Strickland v.

12 Washington, 466 U.S. 668, 694 (1984)).

13   {34}   We conclude that Defendant has failed to demonstrate prejudice, a

14 deficiency which is fatal to his claim of ineffective assistance of counsel. First,

15 regarding Defendant’s assertion that defense counsel failed to impeach Mr.

16 Hawkins with a prior criminal conviction, the State preemptively raised the issue

17 outside the presence of the jury during trial, stating that while Mr. Hawkins had

18 been a defendant in a misdemeanor attempted receiving/transferring a stolen motor

19 vehicle case, he was not convicted and the matter had been resolved by use of a

20 pre-prosecution probation program, and thus the matter could not properly be used


                                            21
      
                                                                                           


 1 for impeachment purposes. Rule 11-609(A) requires evidence of a criminal

 2 conviction, and not merely evidence of a witness having been charged with a

 3 crime, to attack that witness’s character for truthfulness. Here, defense counsel

 4 conceded     that   Mr.   Hawkins    had        not   been   convicted   of   attempted

 5 receiving/transferring a stolen motor vehicle, and on appeal failed to explain why

 6 Mr. Hawkins’ criminal case was nonetheless usable for impeachment purposes.

 7 See State v. Guerra, 2012-NMSC-014, ¶ 21, 278 P.3d 1031 (holding appellate

 8 courts are not obligated to review unclear or undeveloped arguments).

 9   {35}   Second, because we have upheld the district court’s ruling on the

10 inadmissibility of Mr. Montoya’s testimony, any delay in the disclosure of his

11 identity as a witness could not have prejudiced Defendant. Third, defense counsel’s

12 decision not to call Ms. Lucero as a witness was within the bounds of trial strategy

13 afforded to criminal defense attorneys. See Lytle, 2001-NMSC-016, ¶ 43 (stating

14 that on appeal, we will not second guess the trial strategy and tactics of defense

15 counsel). We base this conclusion on Ms. Lucero’s brief testimony, given outside

16 the presence of the jury, concerning a conversation the day of the robbery between

17 Defendant and Mr. Lucero regarding “drugs and [her] vehicle.” Mr. Lucero told

18 Ms. Lucero that he agreed to give Defendant a ride to the Hawkins’ house in

19 exchange for drugs. Ms. Lucero did not see Mr. Lucero and Defendant leave

20 together, nor did she hear discussions about planning a kidnapping or robbery.


                                              22
      
                                                                                             


 1 Following her testimony, defense counsel made the strategic decision not to call

 2 her to testify.

 3   {36}   Last, as discussed previously, Defendant failed to demonstrate that he was

 4 prejudiced by defense counsel’s health issues and alleged attendant lack of

 5 preparation in the months prior to trial. While nothing in our decision today

 6 prevents Defendant from pursuing a future habeas corpus proceeding based on

 7 defense counsel’s constitutional effectiveness vis-à-vis his pretrial illness, we

 8 cannot make a determination of prejudice in the first instance on the record before

 9 us. See State v. Crocco, 2014-NMSC-016, ¶ 24, 327 P.3d 1068 (“If facts beyond

10 those in the record on appeal could establish a legitimate claim of ineffective

11 assistance of counsel, Defendant may assert it in a habeas corpus proceeding where

12 an adequate factual record can be developed for a court to make a reasoned

13 determination of the issues.”).

14   {37}   Because Defendant has not shown that he suffered prejudice as a result of

15 defense counsel’s representation, he has failed to establish a prima facie case of

16 ineffective assistance of counsel, as is required in order to prevail on this issue on

17 direct appeal. Accordingly, we decline to remand to the district court for an

18 evidentiary hearing. See State v. Castro, 2017-NMSC-027, ¶¶ 35-36, 402 P.3d 688

19 (holding defendant’s claim of ineffective assistance of counsel “more properly




                                             23
      
                                                                                              


 1 brought through habeas corpus petition” because “there are insufficient facts in the

 2 record” without defense counsel’s “response to these contentions”).

 3 VI.      We Decline to Review Defendant’s Argument That the District Court
 4          Erred by Denying Defendant’s Requested Jury Instruction Concerning
 5          the Unreliability of Accomplice Testimony

 6   {38}   We decline to review Defendant’s argument that the district court erred by

 7 denying Defendant’s requested jury instruction concerning the unreliability of

 8 accomplice testimony for two reasons. First, the only supposedly binding authority

 9 Defendant offers in support of his argument that Defendant was entitled to a jury

10 instruction about the unreliability of accomplice testimony is Sarracino, 1998-

11 NMSC-022. Defendant’s reliance on this case is mystifying because it holds that a

12 defendant is not entitled to a jury instruction cautioning the jury to weigh

13 accomplice testimony with greater care and caution than that of ordinary witnesses.

14 Id. ¶¶ 8, 17.

15   {39}   Second, Defendant asserts that he sought such a jury instruction in this case,

16 but fails to provide the text of that jury instruction or even a citation to the record

17 showing that the jury instruction was tendered and discussed by the parties during

18 trial. See Rule 12-318(A) NMRA (generally requiring record citations in

19 appellant’s brief in chief in both the summary of proceedings and in support of

20 appellant’s arguments). We are not obligated to comb the record in an attempt to

21 find the proposed jury instruction at issue and then independently ascertain


                                              24
      
                                                                                         


 1 whether this issue was preserved for review, nor are we obligated to do

 2 Defendant’s research. See Guerra, 2012-NMSC-014, ¶ 21 (holding appellate

 3 courts are not obligated to review unclear or undeveloped arguments); State v.

 4 Clifford, 1994-NMSC-048, ¶ 19, 117 N.M. 508, 873 P.2d 254 (reminding counsel

 5 that appellate courts are not required to do the parties’ research).

 6 VII. The Accomplice Testimony Offered Against Defendant Was Sufficient
 7      to Support His Convictions

 8   {40}   Defendant challenges the sufficiency of his accomplices’ testimony as the

 9 primary basis upon which his convictions are supported. In so doing, Defendant

10 offers no argument for why that testimony was unreliable other than the allegation

11 that Mr. Williams and Mr. Lucero received “favorable pleas dependent upon their

12 testimony[.]” Defendant does not provide citation to the record in support of this

13 allegation or explain why Mr. Williams’s and Mr. Lucero’s pleas were more

14 favorable than they would have been absent their agreement to testify against

15 Defendant. The State argues that Defendant impermissibly asks us to reweigh the

16 evidence, that Mr. Williams’ and Mr. Lucero’s testimony was consistent with the

17 statements they provided to law enforcement prior to entering into their plea

18 agreements, and that the jury had discretion to determine witness credibility.

19 A.       Standard of Review

20   {41}   We review sufficiency of the evidence issues deferentially, viewing

21 evidence in “the light most favorable to the guilty verdict, indulging all reasonable
                                             25
      
                                                                                             


 1 inferences and resolving all conflicts in the evidence in favor of the verdict.” State

 2 v. Garcia, 2016-NMSC-034, ¶ 15, 384 P.3d 1076 (internal quotation marks and

 3 citation omitted). We “determine whether substantial evidence of either a direct or

 4 circumstantial nature exists to support a verdict of guilt beyond a reasonable doubt

 5 with respect to every element essential to a conviction.” Id. (internal quotation

 6 marks and citation omitted).

 7          We will not invade the jury’s province as fact-finder by second-
 8          guessing the jury’s decision concerning the credibility of witnesses,
 9          reweighing the evidence, or substituting its judgment for that of the
10          jury. So long as a rational jury could have found beyond a reasonable
11          doubt the essential facts required for a conviction, we will not upset a
12          jury’s conclusions.

13 Id. (alterations, internal quotation marks, and citation omitted).

14 B.       Analysis

15   {42}   Other than his wish that this Court will do what it has repeatedly stated it

16 will not do—substitute our judgment for that of the jury—Defendant offers no

17 basis to conclude that the evidence of his guilt, even though presented most

18 directly by Mr. Williams and Mr. Lucero, is so unreliable as to be legally

19 insufficient. First, both witnesses were questioned at length during trial regarding

20 their plea agreements and their pre-plea agreement statements to detectives.

21 Defense counsel cross-examined Mr. Williams about the contours of his plea

22 agreement, confirming that under his plea agreement he faced nine years of

23 incarceration exposure, which was less than what he would have faced without the
                                              26
      
                                                                                          


 1 plea agreement. Defense counsel also cross-examined Mr. Lucero about his plea

 2 agreement, pointing out that he originally had approximately 100 years of

 3 incarceration exposure on this case including mandatory enhancement based on his

 4 prior felony convictions, but ultimately ended up with six years of incarceration

 5 exposure under his plea agreement.

 6   {43}   Defendant cites only to State v. Brown, 1998-NMSC-037, ¶¶ 16, 24, 126

 7 N.M. 338, 969 P.2d 313, in support of his argument that the accomplices’ plea

 8 agreements alone made their testimony unreliable. Brown, however, did not

 9 consider the issue of accomplice testimony through the prism of evidence

10 sufficiency; instead, it considered whether a defendant’s due process rights were

11 violated by an impermissibly coercive immunity agreement for a testifying

12 accomplice. Id. ¶¶ 17-24. The Brown court ultimately concluded that the

13 accomplice testimony was not inherently unreliable. Id. ¶ 24. Brown is, therefore,

14 distinguishable from the instant case because it concerns use immunity, rather than

15 whether a plea agreement renders accomplice testimony inherently unreliable such

16 that it cannot constitute substantial evidence.

17   {44}   Given that Mr. Williams and Mr. Lucero were extensively questioned by

18 both parties during trial regarding their cooperation and plea agreements, the jury

19 was free to weigh their credibility accordingly. See State v. Candelaria, 2019-

20 NMSC-004, ¶ 45, 434 P.3d 297 (“The jury alone is the judge of the credibility of


                                             27
      
                                                                                              


 1 the witnesses and determines the weight afforded to testimony.”) (internal

 2 quotation marks and citation omitted). “[T]he testimony of a single witness is

 3 sufficient evidence for a conviction.” State v. Soliz, 1969-NMCA-043, ¶ 8, 80

 4 N.M. 297, 454 P.2d 779. We will not otherwise reweigh the evidence the jury

 5 received. See Garcia, 2016-NMSC-034, ¶ 15. We therefore affirm Defendant’s

 6 convictions as supported by substantial evidence.

 7 VIII. The District Court Did Not Err in Denying Defendant’s Request for a
 8       Mistrial Due to the State’s Alleged Mischaracterization in Its Rebuttal
 9       Closing Argument

10   {45}   Defendant asserts that the prosecutor’s statement in its rebuttal closing

11 argument that “the State ultimately, unbeknownst to [Mr. Lucero], dismissed [Ms.

12 Lucero’s] case for lack of evidence[,]” prejudiced him to the extent that reversal

13 and a new trial are required because the statement “undermined one of [Mr.

14 Lucero’s] possible motives to plead guilty and testify against [Defendant].” The

15 State responds that there was no misstatement or misrepresentation, but also that if

16 there was, it was not prejudicial to Defendant. The State also argues that “[i]t is not

17 at all clear that the prosecutor’s comments” implied “that [Ms. Lucero’s] charges

18 were dismissed before [Mr.] Lucero pled,” which the State concedes would have

19 been improper. Additionally, the State asserts that the prosecutor’s statement was

20 supported by the evidence adduced at trial because the State dismissed Ms.

 1 Lucero’s case prior to trial and Mr. Lucero testified that he did not know about the

 2 disposition of those charges.

 3 A.       Standard of Review

 4   {46}   We review a motion for a mistrial for abuse of discretion. State v. Smith,

 5 2016-NMSC-007, ¶ 69, 367 P.3d 420. “The power to declare a mistrial should be

 6 exercised with the greatest caution.” Id. (alteration, internal quotation marks, and

 7 citation omitted). “An argument for mistrial must show that the error committed

 8 constituted legal error, and the error was so substantial as to require a new trial.”

 9 Id. Additionally, “we afford trial judges broad discretion in managing closing

10 argument because they are in the best position to assess the impact of any

11 questionable comment.” State v. Sena, 2018-NMCA-037, ¶ 13, 419 P.3d 1240,

12 cert. granted, 2018-NMCERT-___ (No. S-1-SC-36932, May 25, 2018) (internal

13 quotation marks and citation omitted). “The prosecution has . . . wide latitude

14 during closing arguments[,]” but “[a] prosecutor’s remarks must . . . be based on

15 the evidence or made in response to the defendant’s arguments.” Id.

     B.     Analysis

16   {47}   During Defendant’s closing argument, defense counsel stated, “It’s funny

17 because in [Mr. Lucero’s plea agreement listing coconspirators], [Ms.] Lucero is

18 left out. But here in [Mr. Williams’s plea agreement], Ms. Lucero is in there. So

19 everything is basically just manipulated for the State to get what it’s trying to get,


                                             29
      
                                                                                           


 1 which is a conviction on [Defendant]. They take Ms. Lucero out for Mr. Lucero

 2 and the admission of conspiracy.” Defense counsel continued, “And I’m talking

 3 about [Ms.] Lucero, who is alleged to be part of this conspiracy, did not come in

 4 here and tell you that [Defendant] was the one involved in this conspiracy, who did

 5 this.” The entirety of the prosecutor’s statement in rebuttal closing that is now the

 6 subject of this appeal is the following: “But the defense did actually tell you that

 7 [Mr. Lucero] was lying and made a lot of the fact that [Ms. Lucero] wasn’t brought

 8 here to testify, and there was no agreement for [Mr. Lucero] to testify against [Ms.]

 9 Lucero. Now, what you did hear was that the State ultimately, unbeknownst to Mr.

10 Lucero, dismissed her case for lack of evidence.”

11   {48}   Defendant objected that Ms. Lucero’s case was dismissed “after [Mr.

12 Lucero] pled.” The district court overruled the objection, but instructed the jury

13 that what the attorneys say during closing arguments is “not evidence” and that

14 they would “be the ultimate judge of the facts[,]” and if they remembered

15 something differently than the attorneys, the jury should “go with [their]

16 memories.” After closing arguments when the jury was deliberating, Defendant

17 moved for a mistrial, arguing that the State’s statement “causes extreme prejudice

18 to the defendant, because it undermines the credibility of our closing . . . [a]nd

19 . . . gives the jury the impression that a key motivation for Mr. Lucero to lie was

20 not present when he . . . entered into his plea agreement and made this admission


                                            30
      
                                                                                             


 1 of conspiracy.” The district court denied Defendant’s motion for a mistrial, stating

 2 that “the jury was cautioned a number of times, that what [the] attorneys say is not

 3 evidence, [and] what they need to do is rely on their memories of the testimony[.]”

 4 The district court concluded that Defendant was not prejudiced to the extent

 5 Defendant argued.

 6   {49}   It is not clear to us whether the prosecutor’s statement during rebuttal

 7 closing argument implied that the State dismissed Ms. Lucero’s case before Mr.

 8 Lucero entered into his plea agreement. Regardless, Defendant has not shown that

 9 he was prejudiced by the prosecutor’s statement, much less that he was prejudiced

10 so substantially that the district court abused its considerable discretion in denying

11 Defendant’s motion for a mistrial. Even if the jury believed that Ms. Lucero’s case

12 was dismissed before Mr. Lucero accepted his plea agreement, Mr. Lucero testified

13 and the State reiterated that Mr. Lucero did not know what the ultimate disposition

14 of Ms. Lucero’s case was, much less that the State had dismissed her case shortly

15 before trial. Because he did not know the status of Ms. Lucero’s case, Mr. Lucero

16 could not have been motivated to lie during his testimony in order to obtain

17 favorable treatment of his wife’s criminal case. The district court’s instruction that

18 the attorneys’ argument was not evidence and that the jury should rely on their

19 own memories of the evidence was therefore sufficient to cure any possible

20 prejudice resulting from the prosecutor’s statement, to the extent that any such


                                             31
      
                                                                                           


 1 prejudice exists. See State v. Storey, 2018-NMCA-009, ¶ 60, 410 P.3d 256 (“The

 2 trial court is given, and must exercise, considerable discretion in evaluating the

 3 propriety of argument and in curing any alleged defects.”), cert. denied, ___-

 4 NMCERT-___ (No. S-1-SC-36695, Oct. 31, 2017). We conclude that to the extent

 5 the prosecutor’s statement was improper, Defendant was not prejudiced because of

 6 it, and therefore the district court did not abuse its discretion in denying

 7 Defendant’s motion for a new trial.

 8 IX.      Cumulative Error

 9   {50}   Defendant argues that “the combined effect” of all of the district court’s

10 errors requires reversal. In the absence of any error, much less multiple errors, we

11 disagree, and conclude that there was no cumulative error.

12 CONCLUSION

13   {51}   For the aforementioned reasons, we affirm Defendant’s convictions for

14 armed robbery, conspiracy to commit armed robbery, aggravated burglary, and

15 conspiracy to commit aggravated burglary. We remand with instructions that the

16 district court vacate one of Defendant’s convictions for conspiracy and to

17 resentence Defendant accordingly.

18   {52}   IT IS SO ORDERED.
