    Appeal from the Judgment of Sentence Entered December 21, 2021,
    in the Court of Common Pleas of York County,
    Criminal Division at No(s): CP-67-CR-0001962-2019.
    BEFORE: PANELLA, P.J., OLSON, J., and KUNSELMAN, J.
    MEMORANDUM BY OLSON, J.:                           FILED: JULY 25, 2023
    Appellant, Kashawn Divine Flowers appeals from the judgment of
    sentence imposed after a jury convicted him of first-degree murder.1       We
    affirm.
    On February 4, 2019, the Commonwealth charged Appellant with
    criminal homicide and possession of firearm prohibited following the shooting
    death of Hezekiah Walker on August 18, 2014. Eventually, the case was set
    for trial on one count each of first-degree and third-degree murder.
    On February 6, 2020, the Commonwealth moved in limine to admit
    testimony from two cooperating witnesses about Appellant’s gang affiliation
    and related gang activity. It stated that Appellant associated with the South
    ____________________________________________
    1 18 Pa.C.S.A. § 2502(a).
    J-A09031-23
    Side gang in York City, which had a dispute with the West Side gang after the
    2013 killing of Joseph “Plaga” Gomez.       The Commonwealth outlined its
    witnesses’ expected testimony that on August 17, 2014, Dysheem Jones gave
    Appellant a handgun that Jones used earlier that day, and then Appellant went
    to the West Side “lurking” for the “opposition”—looking to kill an opponent.
    The witnesses would describe that Appellant told them that he saw Walker,
    asked where he was from, and shot him in the head. The witnesses would
    also state how their group would dispose of handguns by putting them in safes
    or burying them.
    Appellant responded on February 28, 2020, objecting to (a) testimony
    that he was “in a gang,” (b) references to the South Side or West Side, (c)
    testimony about “lurking” or “opposition,” and (d) testimony about the killing
    of Joseph Gomez in 2013. Response, 2/28/20, at 3. At argument before the
    trial court on May 27, 2021, Appellant further emphasized his position that
    the term “gang” was unnecessary and prejudicial.
    The trial court indicated its concern that the Commonwealth witnesses
    would testify as to general actions of other gang members in disposing of
    guns. N.T., 5/27/21, at 5–6. However, the trial court ruled that the term
    “gang” was not overly prejudicial and granted the Commonwealth’s first
    motion in limine in full. Id.
    On October 1, 2021, the Commonwealth filed its second motion in
    limine, seeking to admit expert testimony about gangs.       Appellant filed a
    -2-
    J-A09031-23
    response in opposition on October 12, 2021.         The trial court granted the
    motion the same day.
    The case proceeded to a jury trial on October 18–21, 2021. The trial
    court detailed the pertinent facts at trial as follows:
    On August 18, 2014, at 6:00 A.M. Officer Derrick Millhouse
    responded to the 300 block of West King Street [in York City] for
    reports of a possible shooting and a man down. When Officer
    Millhouse arrived at the scene, he observed the victim with an
    obvious gunshot wound to the head [lying] on the sidewalk with
    a large pool of blood around his head. Officers secured the scene
    and found spent shell casings, bullet fragments, and damage to
    one of the nearby houses. There were no eyewitnesses of the
    shooting, no gun was found, and no DNA evidence was recovered
    from the scene. On August 18, 2014, Brenda McCleary was living
    [nearby] and heard three gunshots around 2:30 a.m. outside of
    her home. Additionally, Edward Daniels who lives [nearby] heard
    gunshots from his home on the date of the incident between 2:40
    a.m. and 3:00 a.m.
    The victim was identified as Hezekiah Walker, and Dr.
    Samuel Land of Forensic Pathology Associates, an expert in
    forensic pathology, performed an autopsy on Hezekiah Walker and
    determined the cause of death was a gunshot wound to the head.
    Additionally, the autopsy report indicated that Hezekiah Walker
    sustained a perforating gunshot wound to his right leg. Dr. Land
    ruled Hezekiah Walker’s manner of death a homicide.
    Detective Anthony Fetrow of the York City Police
    Department was assigned as the lead detective to investigate the
    death of Hezekiah Walker. Detective Fetrow determined Hezekiah
    Walker’s last known location was 600 West College Avenue, a
    corner house on West Street and College Avenue. 600 West
    College was the home of Zach Williams, Hezekiah Walker’s friend,
    which was next to a large business. Detective Fetrow obtained
    the large business[’] surveillance video from August 18, 2014 to
    determine Hezekiah Walker’s whereabouts between the time he
    left Zach William[s’] home and when the shooting occurred.
    Hezekiah Walker was seen in camera view for approximately three
    minutes from 2:20 to 2:23 a.m. Next, Detective Fetrow obtained
    footage from St. Paul’s Evangelical Congregational Church at 450
    -3-
    J-A09031-23
    West King Street in York which showed Hezekiah Walker walking
    on the south sidewalk toward Penn Street [at 2:35 a.m.]
    Additionally, Detective Fetrow obtained surveillance video from
    Elite Property Management on the corner of Penn and King
    Street[s] which showed Hezekiah Walker at 2:37 a.m. on August
    18, 2014. None of the video surveillance obtained showed
    Hezekiah Walker having contact with any other individuals.
    Hezekiah Walker’s cell phone was found at the crime scene
    and [o]fficers conducted a forensic analysis to review any
    communication that Hezekiah had in the hours leading up to his
    death. Hezekiah Walker exchanged text messages with two ex-
    girlfriends between 2:33 a.m. and 2:39 a.m. Based on the
    surveillance video and text message communications, [Detective]
    Fetrow was able to determine the shooting occurred sometime
    around 2:37 a.m. An analysis of Appellant’s cell phone records
    indicated that he was near the crime scene between 2:27 a.m.
    and 2:46 a.m. on August 18, 2014, the day the shooting occurred.
    Through an investigation, Detective Wesley Kahley, an
    expert on gang culture and gang affiliation, determined that
    Appellant represented himself as a member of the [S]outh [S]ide
    criminal street gang in York.        Detective Kahley reviewed
    Appellant’s social media posts and conversation during his
    investigation.    Appellant made various posts claiming his
    association with the [S]outh [S]ide criminal street gang including:
    (1) “[Ots] be my squad,” short for “only the south be my squad,”
    (2) “ClaimGangLife,” and (3) “#600K,” indicating disrespect to
    opposition as “600” refers to the [W]est [S]ide and “K” is short for
    “kill.” Additionally, Appellant has a “F-O-E” tattoo meaning
    “family over everything,” indicative of Appellant’s involvement in
    gang culture.
    Acquaintances of Appellant, Marcos Martinez and Raymond
    Bruno Carrasquillo, testified that Appellant and other individuals
    from the South Side used the term or phrase “1017” to refer to
    their friend, Joseph Gomez, also known as Plaga Two Times
    (“Plaga”), who passed away in April of 2013, during a shootout
    with Flair Griggs, an individual who hung out in the “West End.”
    [Martinez and Carrasquillo] testified that … “beef” and “ops,” were
    two terms used to describe the opposition between the “South
    Side” and “West Side” “groups” of York. Plaga’s death caused beef
    between the South Side and West Side because it made a lot of
    people angry, including Appellant. Appellant had two tattoos in
    memory of Plaga’s death, one that stated, “RIP Plaga,” and
    -4-
    J-A09031-23
    another “1017.” [Martinez] went on to testify that Appellant
    “wanted to get revenge” for Plaga’s death, and [Carrasquillo]
    testified that Appellant was “revengeful” of Plaga’s death.
    Additionally, [Martinez] testified that he and other
    individuals from the South Side were involved in a shootout on
    August 17, 2014, with individuals he believed to be from the West
    End. On the same day of this shootout, Appellant came to
    [Martinez’s] home around 12:00 in the afternoon and retrieved a
    gun, specifically a Colt .45, which was used in the earlier shootout.
    Later that night, Appellant returned to [Martinez’s] home and
    explained that he drove out West looking for “ops” and shot
    someone in the head after the individual told Appellant that he
    was from out West. [Firearm toolmark analysis revealed that the
    cartridge casings from the shooting on August 18 were discharged
    from one of the same guns as the earlier shootout on August 17.]
    [Martinez] observed Appellant to be “hype[d],” “excited,”
    and “happy” when informing [Martinez] and other South Side
    individuals that he shot someone from the West End. While
    incarcerated, Appellant was bragging to [Carrasquillo] that he had
    a “head shot,” meaning he shot someone in the head and killed
    them, on King Street. Appellant proceeded to tell [Carrasquillo]
    that on August 18, 2014, he was very emotional and decided that
    he would shoot whoever he saw walking on the West Side.
    [Carrasquillo] said Appellant appeared happy and excited about
    the shooting.
    Trial Court Opinion, 4/18/22, at 1–5 (record citations omitted).
    The jury found Appellant guilty of first-degree murder. On December
    21, 2021, the trial court sentenced Appellant to life in prison without the
    possibility of parole. Appellant filed a timely post-sentence motion, which the
    trial court denied without opinion on January 3, 2022.         Appellant timely
    appealed. Both Appellant and the trial court complied with Pennsylvania Rule
    of Appellate Procedure 1925.
    Appellant raises five issues on appeal:
    -5-
    J-A09031-23
    A. Was the evidence insufficient to prove, beyond a reasonable
    doubt, that [Appellant] committed First Degree Murder where:
    (a) there was no eyewitness to the shooting (b) there was no
    forensic evidence attributable to [Appellant], e.g., fingerprints
    or DNA, found either on the victim or even in the vicinity of the
    offense; (c) testimony from two individuals purportedly
    implicating [Appellant] in the offense was so corrupt, polluted
    and contradictory as to make any verdict based thereon
    unreliable and pure conjecture, and (d) the cell triangulation
    testimony was, at best, speculative, thus requiring the
    conviction be reversed and vacated?
    B. Alternatively, was the verdict against the weight of the
    evidence and so contrary to the evidence as to shock one’s
    sense of justice, thus requiring that the conviction be reversed,
    and a new trial granted?
    C. Did the trial court abuse its discretion, err and infringe on
    [Appellant’s] right to due process of law as guaranteed by the
    [federal and state constitutions] by granting the prosecution’s
    motion in limine to admit at trial certain testimony pursuant to
    Rule 404(b) where: (a) the testimony was not relevant, as it
    did not make any material fact at issue more of less probable;
    (b) the testimony was rank propensity evidence which sought
    to establish [Appellant] as a member of a “criminal street gang”
    who had the propensity to engage in violent acts and who may
    have been involved in other uncharged crimes; (c) none of the
    “permitted uses” set forth in Rule 404(b)(2) which would
    permit this propensity evidence applied; and (d) even if some
    permitted use of the bad character evidence existed, the
    probative value of the evidence was outweighed by its potential
    for unfair prejudice, thus requiring that the conviction be
    reversed and a new trial granted?
    D. Did the trial court abuse its discretion, err and infringe on
    [Appellant’s] right to due process of law as guaranteed by the
    [federal and state constitutions] by allowing the prosecution to
    present expert testimony concerning gang activities and
    [Appellant’s] alleged gang affiliation where: (a) to the extent
    that any evidence concerning [Appellant’s] involvement with a
    gang was relevant, such type of evidence is not beyond the
    knowledge of an average layperson, and expert testimony was
    not needed to help the jury understand the evidence or
    determine a fact in issue; and (b) the expert testimony only
    emphasized and bolstered the general nature and
    -6-
    J-A09031-23
    dangerousness of gang activity and the propensity of gang
    members to engage in criminal conduct, thus requiring that the
    conviction be reversed and a new trial granted?
    E. Did the trial court abuse its discretion, err and infringe on
    [Appellant’s] right to due process of law as guaranteed by the
    [federal and state constitutions] by denying [Appellant’s]
    motion for a mistrial where the prosecution’s expert on gang
    activities and [Appellant’s] alleged gang affiliation testified that
    gangs are involved in criminal activity, specifically referencing
    drug activity, an offense with which [Appellant] was not
    charged, thus requiring that [Appellant’s] conviction be
    reversed and a new trial granted?
    Appellant’s Brief at 7–8 (excess capitalization omitted).
    A. Sufficiency of the Evidence
    Appellant’s first claim is that the evidence was insufficient to establish
    his identity as the person who killed Walker. He emphasizes the unreliability
    of the evidence against him. Appellant notes that Martinez and Carrasquillo
    had motive to testify favorably for the Commonwealth and gave inconsistent
    accounts of what Appellant told them. He further challenges the accuracy of
    the cell site location information that placed him in the vicinity of the shooting.
    Appellant concludes that in this case, the jury’s verdict could only be the result
    of conjecture and must be overturned.
    A sufficiency challenge “presents a question of law and is subject to our
    plenary review under a de novo standard.” Commonwealth v. Moore, 
    263 A.3d 1193
    , 1205 (Pa. Super. 2021) (citing Commonwealth v. Smith, 
    234 A.3d 576
    , 581 (Pa. 2020)). We determine “whether viewing all the evidence
    admitted at trial in the light most favorable to the verdict winner, there is
    sufficient evidence to enable the fact-finder to find every element of the crime
    -7-
    J-A09031-23
    beyond a reasonable doubt.” Commonwealth v. Williams, 
    255 A.3d 565
    ,
    578 (Pa. Super. 2021) (quoting Commonwealth v. Smith, 
    97 A.3d 782
    , 790
    (Pa. Super. 2014)). A jury is generally “free to believe some, all, or none of
    the Commonwealth’s evidence” and to resolve inconsistencies in favor of
    either party. Commonwealth v. Jacoby, 
    170 A.3d 1065
    , 1078 (Pa. 2017)
    (citing Commonwealth v. Ramtahal, 
    33 A.3d 602
    , 607 (Pa. 2011)).
    Identity, like any element of a crime, can be established by evidence that is
    circumstantial and which “need not be positive and certain.”         Id. at 579
    (quoting Commonwealth v. Jones, 
    954 A.2d 1194
    , 1197 (Pa. Super.
    2008)).
    However, our Supreme Court has recognized “atypical situations” in
    which “the entire body of evidence introduced at trial which furnished the basis
    for an appellant’s conviction is so deficient that it does not reasonably support
    a finding of guilt beyond a reasonable doubt, as a matter of law.” In the
    Interest of J.B., 
    189 A.3d 390
    , 409 (Pa. 2018) (citing Commonwealth v.
    Jackson, 
    66 A.2d 841
    , 843 (Pa. 1949)). In such a case, the reviewing court
    must reject the conjectural findings of fact and find the evidence insufficient.
    
    Id.
     (citations omitted).
    Here, Martinez and Carrasquillo testified that Appellant told them that
    he shot and killed someone on the west side of York, which is consistent with
    Walker’s death.     Their testimony, if believed, was sufficient to identify
    Appellant as the shooter. We hold that this testimony is not so inherently
    unreliable that it is insufficient as a matter of law. Notably, both witnesses
    -8-
    J-A09031-23
    stated that they had abandoned their gang lifestyles and acknowledged any
    expectation of favorable treatment. Further, their testimony was corroborated
    by common elements between what Appellant told them, as well as the
    identification of the casings down the street from where Walker was shot
    coming from the same gun used in the shootout the day before.
    The inconsistencies in testimony were up to the jury to resolve, rather
    than removing the case from consideration. Jacoby, supra. As to Martinez
    and Carrasquillo’s testimony that the shooting occurred around 11 p.m., not
    2:30 a.m., this reflects Appellant’s own misperception of the time he told them
    that he shot Walker. And while McCleary and Daniels did not recall hearing
    any exchange of words before the early morning gunfire, this is logical given
    the time of the shooting and relative volume; a voice, even one shouting down
    the block, may not be heard the same way as a .45-caliber gunshot. The
    totality of the evidence, viewed in a light most favorable to the Commonwealth
    as verdict winner, was therefore sufficient to identify Appellant as the person
    who killed Walker. Appellant’s first claim fails.
    B. Weight of the Evidence
    Appellant’s second claim concerns the denial of his post-sentence
    motion for a new trial based on the weight of the evidence. He argues that
    the trial court abused its discretion by not assessing whether the verdict
    shocked its sense of justice, instead merely deferring to the jury’s findings.
    Had the trial court appropriately reviewed the evidence, Appellant contends,
    -9-
    J-A09031-23
    it would have found that the jury’s verdict was so contrary to the weight of
    the evidence as to shock the trial court’s sense of justice.
    Our Supreme Court has explained the standard to be applied by a trial
    court in ruling on a weight-of-the-evidence challenge as follows:
    An allegation that the verdict is against the weight of the
    evidence is addressed to the discretion of the trial court.
    Commonwealth v. Brown, 
    648 A.2d 1177
     (Pa. 1994). A new
    trial should not be granted because of a mere conflict in the
    testimony or because the judge on the same facts would have
    arrived at a different conclusion. Thompson v. City of Phila.,
    
    493 A.2d 669
    , 672 (Pa. 1985). A trial judge must do more than
    reassess the credibility of the witnesses and allege that he would
    not have assented to the verdict if he were a juror. Trial judges,
    in reviewing a claim that the verdict is against the weight of the
    evidence do not sit as the thirteenth juror. Rather, the role of the
    trial judge is to determine that “notwithstanding all the facts,
    certain facts are so clearly of greater weight that to ignore them
    or to give them equal weight with all the facts is to deny justice.”
    Id. at 674.
    Commonwealth v. Widmer, 
    744 A.2d 745
    , 751–52 (Pa. 2000) (citation
    format altered). Under this standard, a trial court awards relief upon a finding
    that “the jury’s verdict is so contrary to the weight of the evidence as to shock
    one’s sense of justice and the award of a new trial is imperative so that right
    may be given another opportunity to prevail.”      Jacoby, 170 A.3d at 1080
    (quoting Commonwealth v. Clay, 
    64 A.3d 1049
    , 1055 (Pa. 2013)). This
    stands in contrast to an assessment of evidentiary sufficiency, which draws
    reasonable inferences in favor of the Commonwealth and accepts that jurors
    are free to believe any evidence. Id. at 1078.
    - 10 -
    J-A09031-23
    An appellate court, in turn, reviews whether the trial court abused its
    discretion in ruling on the weight claim, not whether the verdict itself was
    against the weight of the evidence. Commonwealth v. Rogers, 
    259 A.3d 539
    , 541 (Pa. Super. 2021) (citing Commonwealth v. Windslowe, 
    158 A.3d 698
    , 712 (Pa. Super. 2017)). “An abuse of discretion is not merely an error
    of judgment, but is rather [1] the overriding or misapplication of the law, [2]
    the exercise of judgment that is manifestly unreasonable, or [3] the result of
    bias, prejudice, ill-will or partiality, as shown by the evidence of record.” 
    Id.
    (quoting Commonwealth v. Santos, 
    176 A.3d 877
    , 882 (Pa. Super. 2017)).
    It is a misapplication of the law, and thus an abuse of discretion, for a trial
    court to deny a weight challenge based only on evidentiary sufficiency.
    Commonwealth v. Sullivan, 
    820 A.2d 795
    , 806–07 (Pa. Super. 2003). This
    Court’s role is then to remand for the trial court to apply the proper standard.
    
    Id.
     at 807 n.12 (citing Widmer, 744 A.2d at 752).
    In reviewing this issue, the trial court set forth the proper legal standard
    to be followed in assessing a weight of the evidence claim. Trial Court Opinion,
    4/18/22, at 9.    (“A true weight of the evidence challenge concedes that
    sufficient evidence exists to sustain the verdict but questions which evidence
    is to be believed. Exclusively, the finder of fact is to determine the weight of
    the evidence and is free to believe all, part, or none of the evidence and to
    determine the credibility of the witnesses. … When reviewing a challenge to
    the weight of the evidence, the verdict may be reversed only if it is so contrary
    - 11 -
    J-A09031-23
    to the evidence as to shock one’s sense of justice.” (footnotes, citations and
    quotation marks omitted)). In applying this correct standard to the case sub
    judice, the trial court found as follows:
    The elements and supporting evidence for the charge[] of [f]irst-
    [d]egree [m]urder are listed in section I [of the trial court’s
    1925(a) opinion].[2] The jury, sitting as the finder of fact for the
    charges, was free to determine the credibility of all witnesses and
    to make inferences based on all the evidence presented at trial.
    Appellant states that “the cell phone triangulation evidence was,
    at best, speculative,” but fails to support this statement with any
    facts or argument; however, the jury was free to determine the
    credibility of the testimony related to Appellant’s cell phone
    records. Further Appellant alleges that “the testimony of [Marcos]
    Martinez and [Raymond] Bruno-Carrasquillo was so corrupt,
    polluted and incredible that no reliable jury verdict could be
    premised on this testimony;” however, the jury, as factfinder was
    free to determine the credibility of each witness, and likely found
    both Martinez and Bruno-Carrasquillo to be credible witnesses,
    and thus found that Appellant informed both Martinez and Bruno-
    Carrasquillo that he has a “headshot” on the [W]est [S]ide on the
    same date that Hezekiah Walker was killed by a gunshot wound
    to the head on the [W]est [S]ide.
    ____________________________________________
    2 In ruling on the sufficiency of the evidence challenge raised by    Appellant,
    the trial court stated as follows:
    [T]he evidence established that Appellant wanted revenge against
    the [W]est [S]ide for the death of his friend, [Joseph Gomez, also
    known as Plaga Two Times], and he told at least two individuals
    that he shot someone on the [W]est [S]ide the same day that
    Hezekiah Walker was shot and killed by a gun shot wound to the
    head on the [W]est [S]ide. Appellant outwardly represented
    himself as being associated with the [S]outh [S]ide criminal street
    gang in York and publicly displayed his affiliation with the [S]outh
    [S]ide by posting about killing individuals on the [W]est [S]ide,
    the [S]outh [S]ide’s opposition []. Additionally the cell phone
    analyst testimony and evidence placed Appellant in the vicinity of
    the crime scene on the date and time of the shooting.”
    Trial Court Opinion, 4/18/22, at 8 (footnotes omitted).
    - 12 -
    J-A09031-23
    Id. at 9-10.       Although the trial court did not expressly state that,
    notwithstanding all the facts, certain facts are so clearly of greater weight that
    to ignore them or give them equal weight with all the facts is to deny justice,
    or that the jury’s verdict is so contrary to the weight of the evidence as to
    shock one’s sense of justice, it is clear that the trial court applied the correct
    legal standard and did not abuse its discretion in denying Appellant’s weight
    of the evidence claim. Accordingly, Appellant’s second issue merits no relief.
    C. Evidence that Appellant Was in a Gang
    Appellant’s third claim is that the trial court erred in admitting testimony
    about his gang affiliation. He submits that this evidence should have been
    excluded under Pennsylvania Rule of Evidence 404 because it showed only
    that he had a propensity for violence and was not relevant for any permissible
    purpose. Further, Appellant argues that the potential for unfair prejudice from
    evidence that he was in a violent “criminal street gang” outweighed any
    probative value.      He posits that the evidence was so pervasive and
    inflammatory that it stripped him of the presumption of innocence and denied
    his right to a fair trial, despite the trial court’s limiting instruction.
    The Commonwealth responds that the trial court properly admitted
    evidence that Appellant was affiliated with a gang.            It explains that the
    evidence was relevant to prove Appellant’s motive and to show the sequence
    of events leading up to the shooting. The Commonwealth also argues that
    - 13 -
    J-A09031-23
    the trial court made no error in finding that the probative value of the evidence
    outweighed the potential that it would unfairly prejudice Appellant.
    This Court reviews pre-trial evidentiary rulings to determine whether the
    trial court abused its discretion. Frazer v. McEntire, 
    265 A.3d 777
    , 783 (Pa.
    Super. 2021) (citing In re Fiedler, 
    132 A.3d 1010
    , 1023 (Pa. Super. 2016)).
    In general, evidence is admissible only if it is relevant. Pa.R.E. 402.
    “Evidence is relevant if it tends to make a material fact more or less probable
    than it would be without the evidence.” Commonwealth v. Lehman, 
    275 A.3d 513
    , 519 (Pa. Super. 2022) (quoting Commonwealth v. Christine, 
    125 A.3d 394
    , 398 (Pa. 2015)); see Pa.R.E. 401. In a criminal case, evidence of
    motive is always relevant. Commonwealth v. Gwaltney, 
    442 A.2d 236
    , 241
    (Pa. 1982) (citing Commonwealth v. Faison, 
    264 A.2d 394
     (Pa. 1970)).
    Rule 404 provides for the exclusion of certain evidence that otherwise
    meets the test for relevance:
    (a) Character Evidence.
    (1) Prohibited Uses. Evidence of a person’s character or character
    trait is not admissible to prove that on a particular occasion the
    person acted in accordance with the character or trait.
    *     *      *
    (b) Other Crimes, Wrongs, or Acts.
    (1) Prohibited Uses. Evidence of any other crime, wrong, or act
    is not admissible to prove a person’s character in order to show
    that on a particular occasion the person acted in accordance with
    the character.
    (2) Permitted Uses. This evidence may be admissible for another
    purpose, such as proving motive, opportunity, intent, preparation,
    plan, knowledge, identity, absence of mistake, or lack of accident.
    - 14 -
    J-A09031-23
    In a criminal case this evidence is admissible only if the probative
    value of the evidence outweighs its potential for unfair prejudice.
    Pa.R.E. 404(a)(1), (b)(1)–(2). Under this rule, the Commonwealth may not
    introduce evidence solely to show that the defendant has a “propensity for
    committing criminal acts.” Commonwealth v. Hairston, 
    84 A.3d 657
    , 665
    (Pa. 2014) (citing Pa.R.E. 404(b)(1) and Commonwealth v. Lark, 
    543 A.2d 491
     (Pa. 1988). However, subject to the balancing test of Rule 404(b)(2),
    evidence of a defendant’s other acts can be admitted if it is relevant for
    another purpose, including motive and the “res gestae exception.” 
    Id.
     A jury
    is presumed to follow instructions to consider evidence of a defendant’s “other
    act” only for one of these limited purposes.           E.g., Commonwealth v.
    Arrington, 
    86 A.3d 831
    , 845 n.11 (Pa. 2014) (citing Commonwealth v.
    Brown, 
    786 A.2d 961
    , 971 (Pa. 2001)).
    Pennsylvania courts have previously addressed admissibility of the
    “other act” of being a gang member. Gang membership is relevant to prove
    motive to kill, such as killing a member of a rival gang. Commonwealth v.
    Gwaltney, 
    442 A.2d 236
    , 241 (Pa. 1982)3 (citing Commonwealth v.
    Faison, 
    264 A.2d 394
     (Pa. 1970)); Commonwealth v. Blackwell, 
    363 A.2d 1316
    , 1317 (Pa. Super. 1976).            However, such evidence of motive is not
    limited to cases where the victim was in a rival gang. For example, when a
    non-gang victim stole drugs from a prospective gang member, a defendant’s
    ____________________________________________
    3 We cite cases from before the adoption of the Pennsylvania Rules of Evidence
    mindful that the Rules were not intended to change existing law.              See
    Commonwealth v. Minich, 
    4 A.3d 1063
    , 1072 (Pa. Super. 2010).
    - 15 -
    J-A09031-23
    gang membership was relevant evidence of his motive for killing the victim as
    a gang enforcer. Commonwealth v. Reid, 
    642 A.2d 453
    , 461 (Pa. 1994).
    As another example, a defendant’s gang membership was relevant to explain
    his participation in shooting at a non-gang member who had sold fake drugs
    to a gang member’s girlfriend. Commonwealth v. Wilson, No. 1470 EDA
    2019, 
    2020 WL 2315616
    , at *5–7 (Pa. Super. May 11, 2020) (unpublished
    memorandum).4 Notably, the relevance of gang membership is not limited to
    proof of a criminal conspiracy, which is a separate purpose than proof of
    motive to kill. See Gwaltney, 442 A.2d at 241 (describing these purposes
    as two reasons evidence of gang membership was properly admitted at trial).
    Here, Appellant’s gang membership was relevant as evidence of his
    motive for killing Walker.        The Commonwealth’s theory at trial was that
    Appellant went to the West Side territory and shot the first person he saw
    there. That Appellant was in the South Side gang makes this more likely and
    helps explain his motive in doing so—revenge over the death of Plaga the
    previous year at the hands of a West Side gang member.
    Further, the trial court did not abuse its discretion in balancing the
    probative value and potential for unfair prejudice stemming from evidence
    that Appellant was in the South Side gang. N.T., 5/27/21, at 5–6. The court
    addressed concerns about the breadth of the Commonwealth’s evidence and
    ____________________________________________

    their persuasive value. Superior Court Operating Procedures § 65.37.
    - 16 -
    J-A09031-23
    found that using the word “gang” would not be overly prejudicial.5 Moreover,
    the trial court instructed the jury that it could consider the evidence of
    Appellant’s gang involvement only as proof of motive. N.T., 10/20/21, at 394.
    We presume that the jury was able to follow this instruction and thus conclude
    that the trial court did not abuse its discretion in applying the Rule 404(b)(2)
    balancing test. Arrington, supra.
    Appellant’s third claim fails.
    D. Expert Testimony on Gangs
    Appellant’s fourth claim is that the trial court erred in allowing testimony
    from Detective Kahley, who was qualified as an expert in gang membership
    affiliation and identification in York City, and who concluded that Appellant
    ____________________________________________
    5 The only witness who used the word “gang” was Detective Kahley, who
    identified the South Side group as a “criminal street gang.” E.g., N.T.,
    10/20/21, at 338 (emphasis added). We note that “criminal street gang” is a
    well-defined term in federal law and several state statutes. 
    18 U.S.C. § 521
    ;
    see United States v. Green, 
    618 F.3d 120
    , 123 (2d Cir. 2010) (rejecting a
    challenge to the federal definition); see, e.g., 
    Alaska Stat. Ann. § 11.81.900
    (b)(13); 
    Cal. Penal Code § 186.22
    (f); Md. Crim. Law § 9-804
    (amended 2020 to replace “criminal gang” with “criminal organization”); N.J.
    Stat. Ann. § 2C:33-29. By contrast, Pennsylvania law only defines a “criminal
    gang” in an offense that was not charged here. 18 Pa.C.S.A. § 5131(e); see
    42 Pa.C.S.A. § 9720.4 (sentencing enhancement).
    Appellant did not object to Detective Kahley’s use of the phrase “criminal
    street gang” at trial or in his post-sentence motion. He first challenged the
    admissibility of this phrase in his Rule 1925(b) statement. This was too late
    for the trial court to remedy any heightened prejudice caused by the
    detective’s use of this legal term of art. Therefore, Appellant waived any
    challenge to the phrase “criminal street gang.” See Commonwealth v.
    Mason, 
    130 A.3d 601
    , 639 & n.47 (Pa. 2015) (finding waiver where a
    defendant first raised a claim in his Rule 1925(b) statement).
    - 17 -
    J-A09031-23
    was in the “South Side Criminal Street Gang.” See N.T., 10/20/21, 320–338.
    Appellant contends that Detective Kahley’s testimony was not necessary or
    helpful for the jury to understand any fact in issue. Given the testimony from
    Martinez, Carrasquillo, and Detective Fetrow, Appellant submits that allowing
    Detective Kahley’s inflammatory, prejudicial testimony was reversible error.
    The Commonwealth responds that Detective Kahley’s expertise went
    beyond that of a layperson and that it was needed to prove Appellant’s gang
    affiliation. It adds that the trial court properly instructed the jury to minimize
    any prejudice stemming from the evidence that Detective Kahley used to
    identify Appellant as a member of the South Side gang.
    As with other evidence, we review the admission of expert testimony to
    determine whether the trial court abused its discretion. Commonwealth v.
    Huggins, 
    68 A.3d 962
    , 965 (Pa. Super. 2013) (citing Commonwealth v.
    Watson, 
    945 A.2d 174
    , 176 (Pa. Super. 2008)). Pennsylvania law permits
    expert testimony where:
    (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.
    Pa.R.E. 702. Testimony from an appropriately qualified expert “is permitted
    only as an aid to the jury when the subject matter is distinctly related to a
    science, skill, or occupation beyond the knowledge or experience of the
    - 18 -
    J-A09031-23
    average layman.”       Commonwealth v. Williams, 
    274 A.3d 722
    , 729 (Pa.
    Super. 2022) (quoting Commonwealth v. Duffey, 
    548 A.2d 1178
    , 1186 (Pa.
    1988)).
    Here, Appellant’s gang affiliation was relevant as evidence of his motive
    for shooting Walker, the first person he encountered when he went to the
    West Side in revenge for the death of Plaga.       Gwaltney, supra.      It was
    therefore a fact in issue in determining Appellant’s guilt.       Furthermore,
    Detective Kahley possessed specialized knowledge beyond that of an average
    layperson that he used to identify Appellant as a member of the South Side
    gang. The detective explained that to identify gang members, he used the
    FBI’s process that includes consideration of numerous criteria.            N.T.,
    10/20/21, at 328. Based on his review of these criteria, he concluded that
    Appellant represented himself as a “member of the South Side Criminal Street
    Gang in York.” Id. at 328–338 (describing factors).6
    While other witnesses provided information about the affiliated groups
    in York City and the background of Plaga’s death, Detective Kahley’s expertise
    ____________________________________________
    6 In his reply brief, Appellant notes that Detective Kahley opined that certain
    hashtags meant “criminal activity related to the gang life,” when they were
    really titles of mix tapes by a rapper. Appellant did not challenge this aspect
    of the detective’s testimony at trial. He did not cross-examine Detective
    Kahley at all. We note that the trial court instructed the jury that another one
    of Appellant’s posts was just song lyrics by the same rapper, which was “not
    to suggest that Appellant in any way has done anything other than pirated the
    lyrics of a rap song relative to an incident that occurred in York City.” N.T.,
    10/20/21, at 314. Cf. Commonwealth v. Williams, 
    245 A.3d 710
    , 722 &
    n.17 (Pa. Super. 2021) (finding a cautionary instruction mitigated any unfair
    prejudice stemming from a jail letter and rap song lyrics used to establish the
    defendant’s identity as the shooter).
    - 19 -
    J-A09031-23
    filled in the gap of concluding that Appellant was a member of the South Side
    gang. Because this was proper expert testimony, the trial court did not abuse
    its discretion in granting the Commonwealth’s motion in limine to admit it.
    Appellant’s fourth claim fails.
    E. Mistrial
    Appellant’s fifth claim is that the trial court erred in denying his motion
    for mistrial after Detective Kahley mentioned drugs. The relevant excerpt of
    testimony is as follows:
    [Assistant District Attorney Lombardo:] I would like to draw your
    attention to 2014 and 2013 in York City. Were there gangs in York
    City at that time?
    [Detective Kahley:] Yes. Throughout my career, there have been
    gangs in York City.
    Q. What kind of gangs have there been?
    A. Our biggest problems come from local criminal street gangs,
    which you also see the national gangs, such as Bloods, Crips, Latin
    Kings. Those forms of group[s] that come to our area. We really
    saw a rise in the mid-’90s of our local street gangs that were kind
    of banding together because of members of the United Blood
    Nation coming into York taking over the drug selling areas.
    N.T., 10/20/21, at 324 (emphasis added).
    Appellant moved for a mistrial based on the reference to drug dealing.
    The trial court denied the motion and provided a cautionary instruction:
    THE COURT: Ladies and gentlemen, in the answer of Detective
    Kahley, there was reference made to gangs who engage in drug
    dealing. This case is not about drug dealing. It never has been.
    They have been instructed that they will—this will not occur. I so
    instruct the detective. Don’t take it as any indication that this is
    a trial about that. It’s clearly not. Thank you.
    - 20 -
    J-A09031-23
    Id. at 326.
    Appellant now argues that the instruction was flawed because it did not
    tell the jury to disregard the testimony and avoid attributing it to Appellant’s
    guilt. Even if the instruction had been proper, Appellant submits that it would
    have been inadequate to cure the error in light of Detective Kahley’s other
    testimony that Appellant was a member of a criminal street gang.                 He
    concludes that the trial court abused its discretion by denying his motion for
    mistrial.
    The Commonwealth responds that Detective Kahley’s remark was not
    intentionally elicited, was not exploited, and was cured of taint by the trial
    court’s instruction. Commonwealth’s Brief at 49 (citing Commonwealth v.
    Manley, 
    985 A.2d 256
    , 266–67 (Pa. Super. 2009)).                   Therefore, the
    Commonwealth argues that the trial court did not abuse its discretion by
    denying Appellant’s motion.
    A ruling on a motion for mistrial is within the discretion of the trial court.
    As such:
    “It is well-settled that the review of a trial court’s denial of a
    motion for a mistrial is limited to determining whether the trial
    court abused its discretion.” . . . “A trial court may grant a mistrial
    only where the incident upon which the motion is based is of such
    a nature that its unavoidable effect is to deprive the defendant of
    a fair trial by preventing the jury from weighing and rendering a
    true verdict.” It is also settled that a mistrial is not necessary
    where cautionary instructions are adequate to overcome any
    potential prejudice. The law presumes that a jury will follow the
    trial court’s instructions.
    - 21 -
    J-A09031-23
    Commonwealth v. Dula, 
    262 A.3d 609
    , 633 (Pa. Super. 2021) (quoting
    Commonwealth v. Gilliam, 
    249 A.3d 257
    , 274–75 (Pa. Super. 2021)).
    Here, we discern no abuse of discretion. Detective Kahley’s reference
    to selling drugs arose while he was providing background information about
    the history of gangs in York City. Notably, the detective did not state that
    Appellant had any involvement with drug sales, nor that this homicide case
    was motivated by drugs. Moreover, the trial court promptly instructed the
    jury that the case was not about drug dealing. Absent any indication that the
    jury disregarded this instruction, we conclude that the trial court’s instruction
    was sufficient to cure any prejudice from Detective Kahley’s solitary remark
    about drug sales. Therefore, the trial court did not abuse its discretion in
    denying Appellant’s motion for a mistrial, and Appellant’s fifth claim fails.
