    WASHINGTON, Senior Judge: Appellants Jacques Parker and Jonathan
    Jenkins were convicted of committing robbery and felony assault on May 10,
    2012. On appeal, both appellants contend that the evidence was insufficient to
    support their convictions and they also raise various evidentiary concerns. In
    addition, appellant Jenkins appeals the denial of his motion for relief under 
    D.C. Code § 23-110
     based on ineffective assistance of his trial counsel.         For the
    following reasons, we affirm the robbery convictions of both appellants, reverse
    and remand appellant Jenkins’ felony assault conviction with instructions to enter a
    judgment for simple assault, and affirm the trial court’s judgment denying Jenkins’
    § 23-110 motion for a new trial without a hearing.
    I. BACKGROUND FACTS AND PROCEDURE
    The complaining witness, Antonio Walls, testified that on January 13, 2012,
    appellant Jenkins was one of three people who knocked him to the ground and
    bruised his eye before his shoes, cellphone, money, and paystubs were stolen.
    Mr. Walls further testified that three days later, on January 16, 2012, he was
    injured and subsequently robbed when he was attacked by approximately fifteen
    3
    people, including appellants Jenkins and Parker. Specifically, Mr. Walls testified
    that he encountered appellant Jenkins in the hallway of his apartment building and
    that, after Mr. Walls turned down appellant Jenkins’ request for a cigarette, he was
    immediately struck in the face by appellant Jenkins. Mr. Walls then ran outside his
    building and was immediately attacked by approximately fifteen people who
    knocked him to the ground and continuously kicked and struck him. Mr. Walls
    testified that some of his assailants wore masks but that appellants had their masks
    rolled up, and Mr. Walls could see their faces. He also testified that while he was
    on the ground, he felt people going through his pockets. Finally, Mr. Walls
    testified that he was able to get up and run away from the group, but that, as he
    tried to run to a convenience store to call the police, some of his assailants caught
    him and took his jacket, keys, and cellphone.
    As a result of his attack, Mr. Walls suffered bruising, “sore and [] hurt” legs,
    a busted lip, and a loose tooth that he “had to push[] . . . back in place.” When
    Officer Pulaski arrived at the scene, she observed Mr. Walls with “some sort of
    paper towel or gauze held up to his mouth,” “blood around his mouth,” and a
    “gash” to his left leg that “wasn’t bleeding.” Mr. Walls was taken to the hospital
    by ambulance where he was given medicine for his pain, a brace, and crutches for
    a “messed up” leg, and may have had X-rays taken before being released that day.
    4
    Medical records indicated that Mr. Walls complained of left knee and left forearm
    pain, but that he remembered the “entire incident,” and had no neck, chest,
    abdominal, pelvic, or lower back pain, and “[n]o broken teeth.”
    On April 4, 2012, appellant Jenkins was charged with two counts of robbery
    and one count of felony assault, while appellant Parker was charged with one count
    each of robbery and felony assault. A pre-trial hearing on appellants’ motion to
    sever took place on April 23, 2012. The trial court subsequently denied the
    motion. At the same hearing, the trial court also considered and denied appellants’
    motion to admit expert witness testimony on the unreliability of eyewitness
    identifications. Trial in this case began on May 1, 2012; appellants were convicted
    of all charges on May 10 and timely appealed.          On appeal, both appellants
    challenge the sufficiency of the evidence of robbery and felony assault, the trial
    court’s response to a jury note, its exclusion of appellants’ expert testimony, the
    admission of certain evidence, and the trial court’s denial of the severance motion.
    Subsequently, appellant Jenkins filed a motion for a new trial under 
    D.C. Code § 23-110
     alleging that his trial counsel was ineffective for agreeing to stipulate to
    Jenkins’ prior incarceration during the trial.
    5
    II. SUFFICIENCY OF THE EVIDENCE
    Faced with a challenge to the sufficiency of the evidence, we view the
    evidence “in the light most favorable to the government, giving full play to the
    right of the [fact finder] to determine credibility, weigh the evidence, and draw
    justifiable inferences of fact, and making no distinction between direct and
    circumstantial evidence.” In re T.M., 
    155 A.3d 400
    , 403 (D.C. 2017) (internal
    quotation marks and citation omitted). We deem the evidence sufficient if “after
    viewing the evidence in the light most favorable to the prosecution, any rational
    trier of fact could have found the essential elements of the crime beyond a
    reasonable doubt.”   Smith v. United States, 
    175 A.3d 623
    , 627 (D.C. 2017)
    (quoting Rivas v. United States, 
    783 A.2d 125
    , 134 (D.C. 2001) (en banc))
    (emphasis in original); see also In re T.M., 155 A.3d at 403 (“The evidence is
    insufficient when the government produces no evidence upon which a reasonable
    mind might fairly conclude guilt beyond a reasonable doubt.”) (internal quotations
    omitted).
    A. Felony Assault
    6
    Appellant Jenkins contends that his conviction for felony assault stemming
    from the January 16, 2012, assault and robbery must be reversed because the
    government presented insufficient evidence that Mr. Walls sustained significant
    bodily injury within the meaning of 
    D.C. Code § 22-404
    (a)(2) (2020 Supp.). He
    asserts that though Mr. Walls went to the hospital and undoubtedly suffered
    “upsetting and painful” injuries, there was no evidence that he suffered significant
    bodily injury or severe pain. We agree that the government produced insufficient
    evidence of Mr. Walls’ injuries to sustain a felony assault conviction.
    Felony assault is committed when a person “unlawfully assaults, or threatens
    another in a menacing manner, and intentionally, knowingly, or recklessly causes
    significant bodily injury to another . . . .” 
    D.C. Code § 22-404
    (a)(2). The statute
    defines “significant bodily injury” as “an injury that requires hospitalization or
    immediate medical attention.” 
    Id.
     But whether “an injured party immediately
    goes to a hospital or seeks other medical attention is not, in itself, determinative
    . . . .” Quintanilla v. United States, 
    62 A.3d 1261
    , 1264 (D.C. 2013). Nor is the
    statutory standard satisfied by evidence of “everyday remedies such as ice packs,
    bandages, and self-administered over-the-counter medications . . . whether
    administered by a medical professional or with self-help.” 
    Id. at 1265
    . The
    professional medical attention required by the statute must be aimed at one of two
    7
    ends: “preventing long-term physical damage and other potentially permanent
    injuries” or “abating pain that is severe” rather than “lesser, short-term hurts.” 
    Id.
    (internal quotation marks omitted). Thus, the relevant inquiry is not whether
    “immediate medical attention or hospitalization” occurred, but rather “whether
    medical treatment beyond what one can administer himself is immediately required
    to prevent long-term physical damage, possible disability, disfigurement, or severe
    pain.” In re D.P., 
    122 A.3d 903
    , 912 (D.C. 2015) (internal quotations omitted).
    Applying these standards, we conclude that a reasonable jury could not have
    found that Mr. Walls’ injuries were “significant.” Though the attack on Mr. Walls
    was undoubtedly violent and traumatic, the evidence fails to show that immediate
    medical attention was required to prevent long-term physical damage or other
    potentially permanent injuries. While Mr. Walls received medicine for his pain, a
    brace, and crutches after going to the hospital, the government failed to elicit any
    testimony from Mr. Walls about his need for prompt medical attention, and did not
    call either the paramedics who arrived on the scene or his treating physician to fill
    that gap in his testimony. Further, nowhere does the record “suggest that [his]
    injuries demanded treatment of a higher order, requiring true medical expertise,
    rather than everyday remedies such as ice packs, bandages, and self-administrated
    8
    over-the-counter medications.” Wilson v. United States, 
    140 A.3d 1212
    , 1218
    (D.C. 2016) (internal quotations omitted).
    Although Mr. Walls testified that he thought X-rays may have been taken at
    the hospital, no evidence was presented that X-rays were actually taken, or what it
    was about his injuries that would have prompted a doctor to order X-rays. Cf.
    Cheeks v. United States, 
    168 A.3d 691
    , 697-98 (D.C. 2017) (discussing doctor’s
    testimony describing how “extensive bodily injuries attributable to the beating . . .
    led her to order CAT tests to determine whether [the victim] had sustained brain
    damage, broken bones, or other serious internal injuries”). Similarly, the record is
    silent on “whether the medication [Mr. Walls received at the hospital] required a
    doctor’s prescription or was available over the counter[,]” or whether Mr. Walls
    used that medication, the brace, or the crutches after leaving the hospital. Teneyck
    v. United States, 
    112 A.3d 906
    , 911 (D.C. 2015). Nor does the record provide any
    basis to reach the conclusion that Mr. Walls suffered “long-term physical damage,
    [] disability, disfigurement, or severe pain” from the loose tooth that he himself
    pushed back into place. In re D.P., 
    122 A.3d at 912
    . In sum, the government’s
    evidence did nothing more than invite jurors to speculate that because Mr. Walls
    sought and received medical diagnosis and treatment, his injuries required
    “hospitalization or immediate medical attention.” 
    D.C. Code § 22-404
    (a)(2); see
    9
    also Nero v. United States, 
    73 A.3d 153
    , 158-59 (D.C. 2013) (differentiating
    sufficient evidence of felony assault for a potentially “life-threatening” gunshot
    wound suffered by one victim from insufficient evidence of felony assault for
    another gunshot victim requiring only “diagnostic tests, pain medication, and
    wound care”). Because the government failed to produce sufficient evidence that
    Mr. Walls’ injury required treatment “of a higher order,” Quintanilla, 
    62 A.3d at 1265
    , appellant Jenkins’ conviction for felony assault must be reversed.
    While the evidence was insufficient to support appellant Jenkins’ conviction
    for felony assault, the government did introduce sufficient evidence to support a
    conviction for the lesser included offense of simple assault beyond a reasonable
    doubt. We therefore remand the case for an entry of conviction on that offense and
    for resentencing.1    See 
    D.C. Code § 22-404
    (a)(1); Wilson, 140 A.3d at 1220
    (internal citation omitted).
    1
    Appellant Parker did not raise the same direct challenge to the sufficiency
    of the evidence for his felony assault conviction and appears to have served his
    sentence for felony assault concurrent to his robbery sentence while this appeal
    was pending. Nevertheless, because the evidence supporting appellant Parker’s
    felony assault conviction is the same, “the trial court may, after hearing from the
    parties, determine whether [his] conviction should [also] be reversed” and
    reentered as a simple assault conviction “in the interest of justice.” Perez v. United
    States, 
    968 A.2d 39
    , 105-06 (D.C. 2009).
    10
    B. Robbery
    Next, both appellants argue that even if there is sufficient evidence of their
    participation in the group assault on Mr. Walls to sustain their convictions for
    simple assault, there is no evidence that they participated in the robbery or
    intended to rob Mr. Walls on January 16, 2012. Thus, they contend that their
    robbery convictions based on an aiding and abetting theory must be overturned.
    We disagree.
    To sustain a conviction under an aiding and abetting theory, the government
    must prove that (1) the principal committed a crime; (2) the defendant “assisted or
    participated in its commission”; and (3) the defendant’s participation “was with
    guilty knowledge.” Evans v. United States, 
    160 A.3d 1155
    , 1160 (D.C. 2017)
    (internal quotation omitted).   Because robbery is a specific intent crime, the
    evidence must also show that the appellants had the specific intent to aid and abet
    the robbery. See Lancaster v. United States, 
    975 A.2d 168
    , 174 (D.C. 2009)
    (“Because armed robbery is a specific-intent crime, the government must prove
    that the aider and abettor shared the same mens rea required of the principals — in
    this case, the specific intent to steal from Greene.”); see also Williams v. United
    States, 
    113 A.3d 554
    , 560-61 (D.C. 2015) (noting that to establish robbery under
    11
    
    D.C. Code § 22-2801
    , the government must prove: “(1) a felonious taking, (2)
    accompanied by . . . the carrying away, of (3) personal property of value, (4) from
    the person of another or in his presence, (5) against his will, (6) by violence or by
    putting him in fear, (7) [with] the intention to steal” (original brackets omitted)).2
    The evidence in this case was sufficient for a jury to find that appellants
    aided and abetted the robbery beyond a reasonable doubt based on the evidence
    presented that appellants were leading and/or participating in the violence that sets
    robbery apart from simple theft. See 
    id.
     After being confronted and struck in the
    face by appellant Jenkins inside his apartment building, Mr. Walls ran out of the
    building and was immediately attacked by approximately fifteen people, including
    appellant Parker. After Mr. Walls got up and began to flee from the second attack,
    several of his attackers caught up to him and stripped him of his jacket, keys, and
    cellphone before he was able to escape. Given these facts, a reasonable jury was
    entitled to view the entire attack on January 16, as a coordinated venture by a
    group of assailants.     Therefore, viewed in the light most favorable to the
    government, this evidence supports a “reasonable inference” that appellants’
    individual assaults on Mr. Walls were undertaken in conjunction with the group’s
    2
    Recently, however, we have expressed concern regarding the use of
    specific intent and general intent as categories of mens rea. See Carrell v. United
    States, 
    165 A.3d 314
    , 323-34 & nn. 26 & 27 (D.C. 2017) (en banc).
    12
    efforts to take his property. Evans, 160 A.3d at 1161. Thus, we affirm appellants’
    robbery convictions because “proof of conduct which [so] designedly encourages
    or facilitates a crime [] support[s] an inference of guilty participation in the crime
    as an aider and abettor.” Id. (internal quotations omitted).
    III. JURY NOTE AND REPLY
    Consistent with their argument that the evidence was insufficient to convict
    them of aiding and abetting the robbery in this case, appellants argue that the trial
    court erred by failing to respond “No” to a jury note that asked whether appellants’
    assaultive conduct could result in their being convicted of aiding and abetting in a
    subsequent robbery by opening the door for the robbery even if there was no
    evidence of appellants’ express intent to participate in the robbery.           More
    specifically, the jury asked: “If in the commission of a crime, a defendant opens
    the door for other crimes committed by other people, without his express intent, is
    the defendant guilty of any subsequent crimes by way of aiding and abetting?”
    The trial judge discussed the note with counsel and appellants’ counsel urged the
    court to respond by merely saying “No.” The trial judge commented that he did
    not understand the “new phrase” about “open[ing] the door for other crimes to be
    committed” and did not “have any idea what[]” was in the jury’s “mind” because
    13
    the aiding and abetting instruction previously given was already clear and
    adequately addressed intent. Ultimately, the trial court decided not to respond
    “no” and that the jury instructions that had been previously provided appropriately
    answered the jury’s question. Thus, the trial court replied: “In response to your
    note concerning aiding and abetting, I direct you[r] attention to the instruction
    numbered ‘3200 4.02’ within your package of instructions. I am unable to give
    you any further clarifying instruction on that subject.” Instruction 3200 4.02 reads
    as follows:
    To find that a defendant aided and abetted in committing
    a crime, you must find that the defendant knowingly
    associated himself with the commission of the crime, that
    he participated in the crime as something he wished to
    bring about, and that he intended by his actions to make
    it succeed. Some affirmative conduct by the defendant in
    planning or carrying out the crime is necessary . . . . The
    government is not required to prove that anyone
    discussed or agreed upon a specific time or method of
    committing the crime . . . that the crime was committed
    in a particular way[,] planned[,] or agreed upon; nor . . .
    that the principal offender and the person alleged to be
    the aider and abettor directly communicated with each
    other . . . . With respect to these offenses, regardless of
    whether the defendant is an aider and abettor or a
    principal offender, the government must prove beyond a
    reasonable doubt that the defendant personally acted with
    the intent as defined in each of the respective instructions
    . . . . It is sufficient if you find beyond a reasonable
    doubt that the crime was committed by someone and that
    the defendant knowingly and intentionally aided and
    abetted in committing the crime.
    14
    Earlier, the trial court had discussed the intent necessary to convict appellants of
    each of the underlying offenses. For robbery, the trial court made it clear that the
    government had to prove “that the defendant intended to deprive the complainant
    of his property and take it for his own use.” As for assault, the trial court stated
    that the defendant had to act “voluntarily and on purpose and not by mistake or
    accident.”
    In general, “the decision on what further instructions, if any, to give in
    response to a jury question lies within the sound discretion of the trial court, and
    absent abuse of that discretion we will not reverse.” (Jeremiah) Gray v. United
    States, 
    79 A.3d 326
    , 337 (D.C. 2013) (internal brackets and quotations omitted).
    And we have recognized that “[t]elling jurors to refer back to their original charge
    may be appropriate in some circumstances” where the “initial instructions
    ‘accurately and thoroughly provided the elements and definitions of the crimes
    charged.’” Euceda v. United States, 
    66 A.3d 994
    , 1008 (D.C. 2013) (quoting
    United States v. Beckman, 
    222 F.3d 512
    , 521 (8th Cir. 2000)). But, telling jurors
    to refer back to the original instruction is only permissible when doing so will
    address the jury’s confusion with “concrete accuracy.” (Jeremiah) Gray, 79 A.3d
    at 337 (internal quotations omitted).
    15
    Therefore, the question on appeal is whether the aiding and abetting
    instruction provided the jurors with the necessary understanding to address their
    confusion. See id. at 338. On appeal, appellants press the argument that the trial
    court erred by not responding to the jury’s question by simply saying “No.”
    However, the answer to the jury’s question would be “No” only if the jury believed
    the defendants lacked the intent to commit the subsequent robbery. If the jury
    believed the defendants had the intent to commit the robbery but simply did not
    explicitly express it to their confederates, answering the jury’s question with a
    “No” would have been misleading. Referring the jury back to the aiding and
    abetting instruction directly addressed those uncertainties while providing
    sufficient clarification for the ambiguous hypothetical question posed by the jury.
    First, the jury note asks how aiding and abetting applies when a defendant
    commits a crime that creates an opportunity for other people to commit separate
    crimes, without an express intent between defendants to commit multiple crimes.
    The aiding and abetting instruction states in pertinent part that “[t]o find that a
    defendant aided and abetted in committing a crime, you must find that the
    defendant knowingly associated himself with the commission of the crime . . . that
    he intended by his actions to make it succeed,” and actively participated “in
    planning or carrying out the crime.” In other words, the aiding and abetting
    16
    instruction informs the jury that, in order to find the defendants guilty of aiding and
    abetting a crime (in this case, the robbery), the jury had to find that the defendants
    knowingly associated themselves with those committing the robbery, intended by
    their actions to make the robbery succeed, and took “[s]ome affirmative conduct …
    in planning or carrying out the crime.” The instruction also makes clear that aiding
    and abetting does not require an express agreement between defendants to carry
    out the affirmative misconduct. As the instruction notes, the “government is not
    required to prove that anyone discussed or agreed upon a specific time or method
    of committing the crime” nor “that the principal offender and the person alleged to
    be the aider and abettor directly communicated with each other.” See Evans, 160
    A.3d at 1161.
    Nonetheless, appellant Parker argues that the jury was confused about the
    level of intent necessary to convict appellants of aiding and abetting the robbery as
    opposed to the intent required to commit the assault. He contends that, because the
    trial court failed to specify that the robbery was the subject of the aiding and
    abetting instruction, and thus, specifically make reference to the government’s
    burden of proving the intent element of robbery, the jury might have convicted
    appellants of aiding and abetting the robbery merely because they committed the
    underlying assault. While it is true that the trial court could have included a direct
    17
    reference to robbery in the aiding and abetting instruction, we see no error in
    failing to do so here because the aiding and abetting instruction specifically
    informs the jury that in order to find a defendant who is guilty of one crime also
    guilty of aiding and abetting another crime, the jury must find “beyond a
    reasonable doubt that the defendant personally acted with the intent” necessary to
    commit the other crime and that he “knowingly and intentionally aided and abetted
    in committing [that] crime.” Thus, while the aiding and abetting instruction given
    in this case did not specifically address the intent necessary to be convicted for
    either of the offenses, it does explicitly tell the jury where to find that information:
    the intent section of the instructions on the “offenses that are charged in this case,”
    specifically assault and robbery. Because we must “consider the instructions as a
    whole,” Green v. United States, 
    718 A.2d 1042
    , 1058 (D.C. 1998), and “a single
    instruction may not be judged in artificial isolation,” Watts v. United States, 
    362 A.2d 706
    , 709 (D.C. 1976) (internal citations and quotations omitted), we are
    satisfied that the trial court’s re-reading of the aiding and abetting instruction
    adequately addressed any confusion the jury may have initially had about applying
    the law in this case. Even appellant Parker acknowledges that there is nothing
    “technically inaccurate” about the trial court’s instruction and, under those
    circumstances, we will not assume the jury misunderstood or overlooked their
    instructions.
    18
    We also reject appellants’ argument that the trial court’s reinstruction failed
    to address the jury’s confusion about the assault “opening the door” to another
    crime. Here, appellants admit that “the incident took place in one continuous
    sequence.” Thus, the record supports the trial court’s finding that the jury’s note
    about “opening the door” to another crime was not “confusing on this evidence.”
    This is not a case where the jury may have been confused because it was given
    instructions applicable to only one of the two factual scenarios with which it was
    presented. Cf. (Jeremiah) Gray, 79 A.3d at 337-38 (requiring clarification where
    note implied that the jury believed one appellant’s role began after the crime
    occurred). To the contrary, no one suggested that the assault and the robbery were
    separate crimes. In fact, appellants’ closing arguments focused on the credibility
    of the complaining witness and never asked the jury to consider whether the
    January 16 assault and robbery were separate crimes. Further, appellants fail to
    explain how specifically referring the jury to the portion of the instruction stating
    what is necessary to connect the individual assaults to a group robbery “was
    confusing as applied to the evidence” of those interrelated crimes.
    Fourth, and finally, appellants contend that the trial court’s response to the
    jury note, and specifically, its statement that it was “unable to give [] any further
    19
    clarifying instruction on the subject,” chilled the jury from asking for further help
    with understanding the relationship between the charged offenses in the context of
    the aiding and abetting instruction. However, it does not appear from the record
    that there was a long delay between the reinstruction and the jury reaching a
    verdict in this case that can be attributed to continued confusion over the aiding
    and abetting instruction, and, because we agree with the trial court that the
    instructions given adequately address the jury’s confusion, there is no basis for
    concluding that the jury would have sought further clarification but for the trial
    court’s statement.   Further, appellants’ requests for the trial court to simply
    respond “No” to the jury’s note neither provided a viable alternative to the aiding
    and abetting instruction nor raised any concern that the court’s previous instruction
    was an incomplete statement on aiding and abetting. See Green, 
    718 A.2d at
    1056-
    57 (requiring distinct and specific objections to jury instructions). For all of these
    reasons, we find the trial court did not abuse its discretion in its response to the
    jury note.
    IV. Eyewitness Identification Expert Testimony
    Appellants next argue that the trial court erroneously excluded their
    eyewitness identification expert.    Before the trial began, appellants sought to
    20
    introduce testimony from Dr. Steven Penrod, a psychology professor who
    specializes in eyewitness identification reliability issues. The trial court precluded
    defense counsel from calling their expert because “[t]he report [was] untimely, and
    the basis of the report [attached to the expert notice] is tenuous at best.” We stayed
    the appeal and remanded the record to the trial court so that it could conduct a
    Dyas3 hearing regarding the admissibility of appellants’ proffered expert
    testimony. Following the Dyas hearing, where the trial court heard testimony from
    both appellants’ and the government’s expert witnesses, the trial court denied
    appellants’ motion to admit their expert testimony. Appellants challenge the trial
    court’s ruling in this appeal.
    A. Admissibility of Expert Testimony
    We review a trial court’s decision on the admissibility of expert testimony
    for abuse of discretion. See Girardot v. United States, 
    92 A.3d 1107
    , 1109 (D.C.
    2014) (internal quotations omitted). When we remanded in 2015 for a decision on
    whether appellants’ expert witness would be allowed to testify, Dyas still governed
    3
    Dyas v. United States, 
    376 A.2d 827
     (D.C. 1977). Dyas adopted and
    expanded upon the Frye standard for admission of expert testimony. See Frye v.
    United States, 
    293 F. 1013
     (Ct. App. D.C. 1923).
    21
    the admissibility of expert testimony.         Under Dyas, expert testimony was
    admissible if:
    (1) the subject matter [is] so distinctively related to some
    science, profession, business or occupation as to be
    beyond the ken of the average layman; (2) the witness
    [has] sufficient skill, knowledge, or experience in that
    field or calling as to make it appear that his opinion or
    inference will probably aid the trier in his search for
    truth; and (3) expert testimony is inadmissible if the state
    of the pertinent art or scientific knowledge does not
    permit a reasonable opinion to be asserted even by an
    expert.
    Dyas, 
    376 A.2d at 832
     (internal quotations omitted).          However, in 2016 we
    replaced the Dyas standard with the Federal Rule of Evidence 702/Daubert
    standard. See Motorola Inc. v. Murray, 
    147 A.3d 751
    , 752 (D.C. 2016) (en banc)
    (adopting the federal standards on admissibility of expert testimony laid out in
    Daubert v. Merrell Dow Pharmaceuticals, Inc., 
    509 U.S. 579
     (1993)). Rather than
    the three-factor test laid out in Dyas, we now review the admissibility of expert
    testimony under the following standard:
    A witness who is qualified as an expert by knowledge,
    skill, experience, training, or education may testify in the
    form of an opinion or otherwise if: (a) the expert’s
    scientific, technical, or other specialized knowledge will
    help the trier of fact to understand the evidence or to
    determine a fact in issue; (b) the testimony is based on
    sufficient facts or data; (c) the testimony is the product of
    reliable principles and methods; and (d) the expert has
    22
    reliably applied the principles and methods to the facts of
    the case.
    Fed. R. Evid. 702; see also Motorola, 147 A.3d at 757 (“We conclude that Rule
    702, with its expanded focus on whether reliable principles and methods have been
    reliably applied, states a rule that is preferable to the Dyas/Frye test.”).
    Following our remand, the trial court held a hearing and issued its order in
    2017, after our decision in Motorola. In its decision, the trial court declined to
    admit the expert testimony based on the Dyas factors, rather than the Rule
    702/Daubert standard we adopted in Motorola. The question of whether Rule 702
    applied retroactively to cases that had already been tried but were not yet final on
    direct appeal was left open in Motorola, see, 147 A.3d at 759, but we have since
    held that “the standards adopted for the admission of expert testimony in Motorola
    apply to all cases . . . that are still ‘pending on direct review or not yet final.’”
    Williams v. United States, 
    210 A.3d 734
    , 743 (D.C. 2019) (citing Davis v. Moore,
    
    772 A.2d 204
    , 226 (D.C. 2001) (en banc)). Because the incorrect standard was
    applied by the trial court, we review the trial court’s decision under harmless error
    standard. See Carrell, 165 A.3d at 327 (“‘On the hearing of any appeal in any
    case, the District of Columbia Court of Appeals shall give judgment after an
    examination of the record without regard to errors or defects which do not affect
    the substantial rights of the parties.’”) (quoting 
    D.C. Code § 11-721
     (e)). “To
    23
    find harmless error, this court must be satisfied ‘with fair assurance, after
    pondering all that happened without stripping the erroneous action from the whole,
    that the judgment was not substantially swayed by the error.’” Smith v. United
    States, 
    666 A.2d 1216
    , 1225 (D.C. 1995) (quoting Kotteakos v. United States, 
    328 U.S. 750
    , 765 (1946)).
    We conclude that the trial court’s error in applying the Dyas factors was
    harmless because the record makes it clear that the trial court’s decision to exclude
    the expert testimony would have been the same if it applied the correct standard.
    We are satisfied that, because Dr. Penrod’s testimony would not “help the trier of
    fact to understand the evidence or to determine a fact in issue,” Fed. R. Evid.
    702(a), the trial court’s decision to exclude his testimony was consistent with the
    Rule 702/Motorola standard. The trial court excluded the expert testimony in part
    because Mr. Walls had seen appellant Parker “around the neighborhood more than
    ten times” and appellant Jenkins “[p]retty much every day,” which allowed the trial
    court to conclude the witness and appellants were “not strangers to each other.”
    Because Dr. Penrod’s testimony centered on cases “where the person being
    identified was not well known” to the witness, and the court determined that there
    was some level of familiarity between the witness and appellants, it concluded that
    “the proffered expert testimony would not aid the jury in any meaningful way.”
    24
    We agree with Dr. Penrod that familiarity exists on a spectrum. Thus, this
    case is not the situation he describes where “[i]f mom is assaulting me, mom is so
    well learned I should be able to recognize her in less than a second,” which is the
    level of familiarity where the factors affecting the reliability of identifications
    would not come into play. But this is also not a case where, as Dr. Penrod implied,
    Mr. Walls was identifying “somebody that [he’d] seen [for] a very brief period of
    time at some prior occasion.” Mr. Walls’ familiarity with appellants Jenkins and
    Parker fell somewhere in between those two poles, which is why the trial court
    determined that Dr. Penrod’s testimony, focused on stranger identifications, would
    ultimately be unhelpful to the jury. 4 Application of the Dyas standard rather than
    the Rule 702/Motorola standard does not change the fact that the trial court has
    discretion to make that determination. See, e.g., Hager v. United States, 
    856 A.2d 1143
    , 1148-49 (D.C. 2004), amended in part on other grounds, 
    861 A.2d 601
    (D.C. 2004), cert. denied, 
    547 U.S. 1035
     (2006) (finding the trial court did not
    abuse its discretion in excluding expert testimony on eyewitness identifications
    because “the studies on which [the expert witness] would have relied concern the
    4
    This conclusion is aided by the government’s expert, who testified that the
    findings from stranger identification research should not be applied to situations
    where the witness has a prior acquaintance with the subject of the identification
    because those situations are “qualitatively different.”
    25
    reliability of a stranger identification, not an identification of a person known to
    the witness, as in this case . . . [thus], it is . . . doubtful that [the expert’s] testimony
    would have been helpful to the jury”); see also United States v. Langan, 
    263 F.3d 613
    , 623 (6th Cir. 2001) (holding expert testimony on eyewitness identifications
    properly excluded under Rule 702 and Daubert because it did not “‘fit’ the
    eyewitness identification in this case”); State v. Guilbert, 
    49 A.3d 705
    , 736-37
    (Conn. 2012) (holding expert testimony properly excluded because the “testimony
    was not applicable to the specific facts of this case and would not have been
    helpful to the jury because most of the eyewitnesses knew the defendant and were
    therefore much less likely to render a mistaken identification”); People v. Abney,
    
    918 N.E.2d 486
    , 496 (N.Y. 2009) (upholding trial court’s exclusion of defendant’s
    expert witness testimony on identifications in part because “defendant was not a
    stranger to either [witness]”); State v. Clopten, 
    223 P.3d 1103
    , 1113 (Utah 2009)
    (“If the eyewitness is identifying someone with whom he or she has been
    acquainted over a substantial period of time . . . then expert testimony is not likely
    to assist the jury in evaluating the accuracy of a witness’s testimony.”). Dr.
    Penrod’s testimony does not meet the first factor in the Rule 702 test for admitting
    expert witness testimony because it would not “help the trier of fact to understand
    the evidence or to determine a fact in issue,” and therefore the trial court’s error in
    applying the Dyas factors was harmless. Fed. R. Evid. 702(a).
    26
    B. Rule 403 Balancing Test
    Even assuming Dr. Penrod’s testimony would have met all of Rule 702’s
    requirements and been otherwise admissible, the trial court did not abuse its
    discretion by keeping out the testimony under Rule 403. See Johnson v. United
    States, 
    683 A.2d 1087
    , 1098-99 (D.C. 1996) (en banc) (adopting probative value
    versus prejudicial effect balancing test of Fed. R. Evid. 403).             Otherwise
    admissible expert testimony may still be excluded by a trial court if “its probative
    value is substantially outweighed by . . . unfair prejudice, confusing the issues, [or]
    misleading the jury . . . .” Motorola, 147 A.3d at 754 (quoting Fed. R. Evid. 403);
    see also Ibn-Tamas v. United States, 
    407 A.2d 626
    , 632 (D.C. 1979) (holding the
    trial court must still apply the 403 balancing test after determining the expert
    testimony’s admissibility). We have recognized that “[e]xpert evidence can be
    both powerful and quite misleading because of the difficulty in evaluating it.”
    Motorola, 147 A.3d at 755 (quoting Daubert, 
    509 U.S. at 595
    ). Therefore, because
    of this risk and as part of the trial court’s gatekeeping function, “the judge in
    weighing possible prejudice against probative force under Rule 403 of the present
    rules exercises more control over experts than over lay witnesses.”          
    Id.
       We
    27
    evaluate the trial court’s decision on the probative versus prejudicial nature of the
    expert testimony for abuse of discretion. Motorola, 147 A.3d at 755.
    Here, the trial court found that “the testimony proffered by the defendant
    would be more prejudicial than probative,” and given that the case “does not
    involve strangers,” the testimony would also be “distracting or confusing [to] the
    jury.” Minor v. United States, 
    57 A.3d 406
    , 419 n.6 (D.C. 2012). While the trial
    court incorrectly addressed the 403 balancing test as part of the second prong of
    Dyas rather than as a separate test of admissibility, we find no prejudice in the trial
    court’s conclusion that Dr. Penrod’s testimony should be excluded under Rule 403.
    As noted above, the thrust of Dr. Penrod’s testimony focused on eyewitness
    identifications involving strangers. His testimony therefore had limited probative
    value in this factual situation, where Mr. Walls was familiar with both appellants,
    and instead his testimony posed a substantial risk of confusing the issue and
    misleading the jury. Under such circumstances, the trial court properly exercised
    its gatekeeping function. See Heath v. United States, 
    26 A.3d 266
    , 282 (D.C.
    2011) (probative value of excluded expert testimony was slight where witness
    knew defendant, and because expert’s opinion rested on research concerning
    stranger identifications, she “simply had too little to say [to the jury] about the
    28
    identifications [her testimony] was meant to undercut”); see also United States v.
    Bartlett, 
    567 F.3d 901
    , 906-07 (7th Cir. 2009) (no abuse of discretion under Rule
    403 to exclude expert witness testimony where four out of six witnesses knew
    defendant well); State v. Williams, 
    119 A.3d 1194
    , 1204-08 (Conn. 2015) (no
    abuse of discretion in excluding expert testimony where witness knew robber as a
    “regular” customer). Ultimately, the trial court did not abuse its discretion in
    excluding the testimony of appellants’ expert under Rule 403.
    V. Other Evidentiary Rulings
    Appellant Jenkins’ other claims of evidentiary errors are unavailing. We
    review a trial court’s evidentiary rulings for abuse of discretion and will reverse
    only if the court’s exercise of discretion is clearly erroneous. See Kozlovska v.
    United States, 
    30 A.3d 799
    , 801 (D.C. 2011). Whether a statement satisfies a
    particular hearsay exception, however, is a question of law that we review de novo.
    
    Id.
    A. Excited Utterances
    29
    Appellant Jenkins takes issue with the trial court’s admission of Mr. Walls’
    911 call and his statements to Officer Pulaski and Detective Bolding shortly after
    that call where Mr. Walls described how he had been robbed. In appellant Jenkins’
    view, the statements were “gratuitous” and “improperly bolster[ed] Walls’
    credibility.” The government responds that these statements were admissible as
    excited utterances. An excited utterance is admissible as an exception to the
    hearsay rule if that statement meets the following criteria:
    (1) The presence of a serious occurrence or startling
    event which causes a state of nervous excitement or
    physical shock in the declarant; (2) a declaration made
    within a reasonably short period of time after the
    occurrence so as to assure the declarant has not reflected
    upon the event and possibly invented a statement; and (3)
    the presence of circumstances that in their totality
    suggest the spontaneity and sincerity of the remark.
    Graure v. United States, 
    18 A.3d 743
    , 755 (D.C. 2011) (internal citation omitted).
    We have made it clear that proof of emotional disturbance is insufficient to justify
    admission of hearsay under this exception; instead, the evidence must establish that
    “the individual’s powers of reflection have been suspended.” Mayhand v. United
    States, 
    127 A.3d 1198
    , 1207 (D.C. 2015); see Graure, 
    18 A.3d at 755
     (“The
    critical factor is that ‘circumstances reasonably justify the conclusion that the
    remarks were not made under the impetus of reflection.’”) (quoting Odemns v.
    United States, 
    901 A.2d 770
    , 777 (D.C. 2006)). The proper standard of proof for
    30
    determining the admissibility of an excited utterance is a preponderance of the
    evidence. See United States v. Woodfolk, 
    656 A.2d 1145
    , 1150 n.14 (D.C. 1995).
    Applying this test to Mr. Walls’ three statements, each one meets the
    definition of an excited utterance. Mr. Walls had been punched, kicked, and hit
    with bottles by a large group of individuals after he ran out of his building. That
    certainly qualifies as a “serious occurrence” and his shaken tone of voice and
    nervous movements when describing the incident to Officer Pulaski support a
    finding of “nervous excitement” or “physical shock.”            Similarly, when one
    combines the temporal proximity of Mr. Walls’ statements with the nature of his
    mannerisms, it is easy to see how his statements satisfy the second element of an
    excited utterance.
    Mr. Walls called 911 at 4:44 p.m. from a grocery store, less than 15 minutes
    after he had been attacked at around 4:30 p.m. See Reyes-Contreras v. United
    States, 
    719 A.2d 503
    , 506 (D.C. 1998) (rejecting challenge to thirty-minute length
    of time between the startling event and the declarant’s statement because declarant
    was still “crying, yelling, very upset . . . .”); Harris v. United States, 
    373 A.2d 590
    ,
    593 (D.C. 1977) (statement made two hours after declarant was shot still held to be
    reliable because victim was suffering effects of the shooting). Evidence was
    31
    presented that Officer Pulaski and Detective Bolding arrived soon thereafter and
    took his statement. Officer Pulaski testified that when he arrived, Mr. Walls was
    “visibly injured,” “shaken and agitated,” and that “[h]e seemed very upset,” and
    Detective Bolding testified that Mr. Walls was injured and “very worried and
    fearful” while speaking to him. This evidence provides sufficient support for the
    finding that Mr. Walls’ statements occurred within a short period after the attack
    and that the effects of the attack were still lingering as to make his statements a
    product of reflex rather than reflection. See Lewis v. United States, 
    938 A.2d 771
    ,
    774, 776 (D.C. 2007) (affirming under excited utterance admissibility of answer to
    police question regarding need for medical attention where declarant was “very,
    very upset” and repeated herself); cf. Pelzer v. United States, 
    166 A.3d 956
    , 961
    (D.C. 2017) (explaining that the trial court was also “obligated to confirm that the
    shocking impact of the incident was sufficiently lasting such that the declarant’s
    powers of reflection were still suspended at the time the proffered statement was
    made”).
    Lastly, when considering whether the circumstances, in their totality,
    suggest sincerity in the declarant’s statements, we have recognized that a
    declarant’s upset and agitated demeanor supports the sincerity of the declarant’s
    remarks in the excited utterance context, as does the presence of fresh injuries. See
    32
    Reyes v. United States, 
    933 A.2d 785
    , 790-91 (D.C. 2007) (noting in light of
    declarant’s upset demeanor and injuries we were “satisfied that any statements
    made by [declarant] . . . were sufficiently reliable to justify their admission as
    excited utterances”). This was not a circumstance where Mr. Walls, after escaping
    an attack, returned home to safety, collected himself, and then gave the police a
    call to document his encounter demonstrating self-awareness. Cf. Mayhand, 127
    A.3d at 1211. Instead, Mr. Walls fled from his attackers to a nearby convenience
    store to call the police for help, then, when they responded, was found “shaken”
    “very upset,” and “moving back and forth.” When responding to questions, Mr.
    Walls was emotional – “shaken” and “angry” – and was also described as “fearful”
    and “unable to give an adequate account of what happened to him.”           These
    circumstances reasonably support the trial court’s finding that Mr. Walls’ remarks
    were both spontaneous and sincere. See, e.g., Goodwine v. United States, 
    990 A.2d 965
    , 966-68 (D.C. 2010) (finding no error in admitting, as an excited utterance, a
    statement to a police officer who asked the assault victim what had happened when
    the statement occurred two to three minutes after the victim called 911 and was
    made in a “fast” and “elevated” voice).
    The common thread between Mr. Walls’ three statements is that they all
    occurred in a “reasonably short period of time” after Mr. Walls’ attack and under
    33
    circumstances from which the trial court could reasonably find that his powers of
    reflection were suspended and his statements were reliable. See Graure, 
    18 A.3d at 755
    . Thus, the trial court did not abuse its discretion in admitting them. 5
    B. Prior Identification
    Appellant Jenkins also challenges three out of court statements; two by
    Detective Bolding, and one by Mr. Wall’s cousin, Jerel Henderson, in which
    Jenkins was identified as the individual who attacked Mr. Walls. He argues that
    the statements are inadmissible hearsay and gratuitously bolster Mr. Walls’
    testimony. The government counters that the statements are not hearsay as they
    fall under the prior-identification exception to the hearsay rule.         While prior
    consistent statements of a witness are generally inadmissible and their “exclusion
    … is intended to avoid the prejudice of unfairly bolstering the witness’ credibility,”
    the “prior identification exception to the [general] rule . . . allows the admission of
    out-of-court statements through the testimony of . . . a third party who was present
    5
    Appellant Jenkins contends that these excited utterances “improperly
    bolster the government’s case” as prior consistent statements. While we agree that
    the general rule is that “prior consistent statements may not be used to bolster an
    unimpeached witness,” Daye v. United States, 
    733 A.2d 321
    , 325 (D.C. 1999)
    (internal quotation omitted), “spontaneous utterance[s]” are an exception to this
    rule. (Henry) Brown v. United States, 
    881 A.2d 586
    , 599 (D.C. 2005) (citing
    Warren v. United States, 
    436 A.2d 821
    , 836 (D.C. 1981)).
    34
    when the identification was made.” Taylor v. United States, 
    866 A.2d 817
    , 822
    (D.C. 2005) (internal citations omitted). A statement is therefore not hearsay under
    the prior-identification exception “if the declarant testifies at the trial . . . and is
    subject to cross-examination concerning the statement and the statement is . . . an
    identification of a person made after perceiving the person.” 
    D.C. Code § 14
    -
    102(b)(3) (2012 Repl.). The description of the offense is admissible under the
    prior-identification exception “only to the extent necessary to make the
    identification understandable to the jury.” Brown v. United States, 
    840 A.2d 82
    , 89
    (D.C. 2004) (internal quotations omitted).       “[D]etailed accounts of the actual
    crime” are inadmissible. 
    Id.
    Here, the statements in question were properly admitted as prior
    identifications. Two of the statements come from Detective Bolding’s testimony
    about the photo array identification procedure with Mr. Walls. Detective Bolding
    testified that Mr. Walls “described [appellant Jenkins] as the leader and stated that
    he was the one that robbed him,” and that Mr. Walls also said appellant Jenkins
    “asked me for a cigarette, then punched me in the mouth, knocked me to the
    ground, and robbed me.” It is undisputed that Mr. Walls, the declarant, was
    identifying appellant Jenkins after having perceived him to Detective Bolding
    when he testified at trial about both statements. A prior identification also requires
    35
    that the declarant “is subject to cross-examination concerning the statement,” 
    D.C. Code § 14-102
    (b)(3), but we have held that a declarant’s availability to be cross-
    examined, along with meeting the other requirements, is enough for a statement to
    be admissible as a prior identification. See, e.g., Brown, 
    840 A.2d at 89
     (“Because
    [declarant] was available for cross-examination, her statement to [the police
    officer] was admissible as substantive evidence”). While Mr. Walls was not cross-
    examined specifically about these statements, he was cross-examined extensively
    about the identification procedures Detective Bolding used during the photo array,
    and there is no evidence in the record that he was unavailable to be recalled after
    Detective Bolding testified about his statements. Thus, Mr. Walls’ statements to
    Detective Bolding were properly admitted as prior identification evidence.6
    The third statement in question comes from Mr. Walls’ conversation with
    his cousin, Jerel Henderson, which occurred approximately one week after the
    attack. Mr. Henderson testified that when he asked Mr. Walls “who jumped him,”
    Mr. Walls responded “[t]he one you said we was going to have a problem out of”;
    6
    Mr. Walls’ statements also do not rise to the level of “detailed accounts of
    the actual crime.” Brown, 
    840 A.2d at 89
    . Both statements give context to Mr.
    Walls’ claim that appellant Jenkins was the person who punched and robbed him,
    and we have held that “[s]ome limited reference in the identification to the criminal
    act is permissible” to make the identification understandable to the jury. Porter v.
    United States, 
    826 A.2d 398
    , 410 (D.C. 2003).
    36
    Mr. Walls also repeated that statement when Mr. Henderson asked Mr. Walls who
    had robbed him a few days earlier. Appellant Jenkins argues that this statement is
    “prejudicial” and a “needless presentation of cumulative evidence,” given Mr.
    Walls’ prior identification of appellant Jenkins during the photo array procedure.
    As an initial point, there is no dispute that the statement meets all three elements of
    the prior identification test. See 
    D.C. Code § 14-102
    (b)(3). Also, rather than
    “unfairly bolstering the witness’ credibility,” Taylor, 
    866 A.2d at 822
    , the
    statement is a separate indication that Mr. Walls knew who appellant Jenkins was
    before the robbery occurred. Thus, the trial court properly credited the statement
    “because the earlier identification has greater probative value than an identification
    made in the courtroom after the suggestions of others and the circumstances of the
    trial may have intervened to create a fancied recognition in the witness’ mind.”
    Graham v. United States, 
    12 A.3d 1159
    , 1165 (D.C. 2011). As with Mr. Walls’
    statements to Detective Bolding, his statement to Mr. Henderson was a prior
    identification. Thus, the trial court did not abuse its discretion in admitting all
    three of Mr. Walls’ statements.
    C. Character Evidence
    37
    Appellant Jenkins next contends that the trial court erred in admitting certain
    evidence of his bad character. Specifically, Jenkins contends that he was unduly
    prejudiced by Mr. Walls’ testimony regarding his response to his cousin Jerel
    Henderson’s question about who had attacked him, to which Mr. Walls answered,
    “[t]he one you said we was going to have a problem out of,” testimony by
    Detective Bolding that he was familiar with appellant Jenkins because of his
    nickname “Goody,” and testimony by Detective Bolding that he kept group
    photographs pulled from Facebook in a binder at the police station and that the
    photographs included a picture of Jenkins.        Appellant Jenkins claims these
    statements should not have been admitted because “there was a substantial risk that
    the jury would misuse this information and infer that Mr. Jenkins was a known
    criminal who was therefore more likely to be guilty of the offense charged.”
    We review the admissibility of such evidence to determine if it is relevant,
    or if it “tends to make the existence or nonexistence of a fact more or less probable
    than would be the case without that evidence.” Winfield v. United States, 
    676 A.2d 1
    , 2 (D.C. 1996) (en banc). This is “not a particularly stringent test.” Rodriguez v.
    United States, 
    915 A.2d 380
    , 385 (D.C. 2007). We also ensure that relevant
    evidence is not unfairly prejudicial. See Gay v. United States, 
    12 A.3d 643
    , 646-47
    (D.C. 2011) (noting that “relevant evidence may be excluded if its probative value
    38
    is substantially outweighed by the danger of unfair prejudice . . . or by
    considerations of . . . needless presentation of cumulative evidence”).
    We conclude that the trial court did not abuse its discretion in admitting
    these statements. First, all three statements are relevant. As discussed above, Mr.
    Walls’ statement to his cousin was relevant because it was a prior identification of
    the person who assaulted Mr. Walls. The other two statements are relevant for the
    same reason.     Detective Bolding identified appellant Jenkins’ nickname as
    “Goody,” which is the same name Mr. Henderson used for appellant Jenkins when
    Mr. Henderson was describing appellant Jenkins as one of the people who were
    regularly “hanging out” in front of Mr. Walls’ building. Detective Bolding’s
    testimony therefore corroborated Mr. Henderson’s statement. Also, the group
    photographs from Facebook depicting appellant Jenkins were relevant because
    they “were the primary means by which [Mr.] Walls identified” appellant Jenkins
    to Detective Bolding.
    Second, the probative value of the statements is not substantially outweighed
    by the danger of unfair prejudice to appellant Jenkins. Mr. Walls’ statement to Mr.
    Henderson about “[t]he one you said we was going to have a problem out of” has
    probative value as a prior identification, and in any event, the trial court minimized
    39
    any potential prejudice arising from this statement by allowing defense counsel to
    cast doubt on Mr. Henderson’s testimony by establishing that Mr. Henderson and
    Mr. Walls did not actually “have any beef with [appellant Jenkins]” and that Mr.
    Henderson did not know Mr. Jenkins.            Further, the statements by Detective
    Bolding regarding appellant Jenkins’ nickname and that he had a photograph of
    appellant Jenkins at the station were not substantially more prejudicial than
    probative. Detective Bolding testified that he “focus[ed his] work on the police
    patrol areas of PSA 703 and 704 . . . which includes Pomeroy Road.” And, as a
    result of this work, Detective Bolding came to know of appellant Jenkins’
    nickname and kept his public Facebook photograph in the station, which is not
    significantly prejudicial if such knowledge was gained through the course of an
    officer’s official duties and is used to explain a suspect’s inclusion in a photo array.
    That was the case here. See Rodriguez, 
    915 A.2d at 384-87
     (evidence that police
    officers recognized appellant from victim’s description based on “prior contacts”
    and knowing him “from the area” admissible to explain why officers included
    appellant’s photograph in photo array for purposes of identification); see also
    Perritt v. United States, 
    640 A.2d 702
    , 704-06 (D.C. 1994) (police officer
    testimony regarding investigative procedures employed in the case was admissible
    because jury was entitled to know the circumstances culminating in courtroom
    identification); (Joseph) Brown v. United States, 
    387 A.2d 728
    , 730 (D.C. 1978)
    40
    (“[T]he importance that a jury know of the reality of a fair pretrial identification
    weighs with more substance in the scales of justice than speculative possibility that
    the jury may conjecture defendant was involved in some offense.”). Finally, the
    risk that these statements caused the jury to “infer that Mr. Jenkins was a known
    criminal” is lessened by the fact that, due to the stipulation, the jury already knew
    appellant Jenkins had been incarcerated. Thus, any prejudice to appellant Jenkins
    from Detective Bolding’s statements did not significantly outweigh their probative
    value as identification evidence. Because the statements are relevant and not
    unfairly prejudicial, the trial court did not abuse its discretion by admitting them.
    VI. Jenkins’ Severance Motion
    Appellant Jenkins also contests the trial court’s denial of his pretrial motion
    to sever his January 13 robbery charge from his January 16 robbery and assault
    charges. 7   “A motion for severance on the ground of prejudicial joinder is
    committed to the sound discretion of the trial court.” Parker v. United States, 
    751 A.2d 943
    , 947 (D.C. 2000) (internal quotations omitted).           To overcome this
    discretion, an appellant must show that the failure to sever charges and order
    7
    Appellant Jenkins does not contest that the two robbery charges were
    “properly . . . joined under Super. Ct. Crim. R. 8(a) . . . .”
    41
    multiple trials under Rule 14 would result in “the most compelling prejudice . . .
    from which the court would be unable to afford protection if both offenses were
    tried together.” 
    Id.
     (internal quotations omitted); see also Bailey v. United States,
    
    10 A.3d 637
    , 642 (D.C. 2010). There is a presumption that cases that share a
    similar character are properly joined, so “a motion to sever will be granted only
    where the evidence would not be mutually admissible at separate trials, or the
    evidence of the multiple charges is likely to be amalgamated in the jury’s mind
    into a single inculpatory mass.” Bailey, 
    10 A.3d at 643
     (internal citations omitted).
    We will reverse the denial of a motion to sever only on a clear showing of abuse of
    discretion. Parker, 
    751 A.2d at 947
     (internal quotation omitted).
    After reviewing the trial record, we do not believe the trial court abused its
    discretion when it denied appellant Jenkins’ severance motion, both because the
    evidence of the two robberies was kept separate and distinct 8 and because evidence
    8
    The trial court did not rely on the crimes being separate and distinct in
    denying the motion to sever, but we “may affirm a judgment on any valid ground,
    including reasons other than those given by the trial court, so long as the appellant
    has had a reasonable opportunity to be heard with respect to the reasoning on
    which the proposed affirmance is to be based.” Campbell v. United States, 
    224 A.3d 205
    , 209-10 (D.C. 2020) (internal brackets, quotation marks, and citations
    omitted). Given that appellant Jenkins raised the risk that the two robberies would
    not be kept separate by the jury at both the motion to sever hearing, and in his
    brief, we conclude that he “has had a reasonable opportunity to be heard” on this
    issue.
    42
    of the two crimes was mutually admissible.        First, the prejudicial impact of
    admitting evidence of both robberies did not lead to “the most compelling
    prejudice,” Parker, 
    751 A.2d at 947
     (internal quotations omitted), because the
    evidence was unlikely “to be amalgamated in the jury’s mind into a single
    inculpatory mass.” Bailey, 
    10 A.3d at 643
    . The robberies happened on different
    days and in different locations, and Mr. Walls testified separately about the two
    incidents. See Gooch v. United States, 
    609 A.2d 259
    , 265 (D.C. 1992) (affirming
    denial of severance motion because robberies were “distinct and uncomplicated”
    and “presented . . . in a distinct manner”). The trial court at several points also
    explained to the jury that the two charges were “separate offenses” and that the
    jury should not let a finding of appellant Jenkins’ guilt of one robbery charge
    “influence your verdict with respect to [the other] charge . . . .”      Juries are
    presumed to follow their instructions. See Harris v. United States, 
    602 A.2d 154
    ,
    165 (D.C. 1992) (en banc). Thus, trying both robbery charges at once did not lead
    to “the most compelling prejudice” because the evidence of each offense was kept
    “separate and distinct.” Parker, 751 A2d at 947 (internal quotations omitted).
    Second, evidence of the two crimes was mutually admissible. Evidence of
    other crimes is mutually admissible if: (1) there is clear and convincing evidence
    the defendant committed the other crime; (2) the evidence is directed to a genuine,
    43
    material and contested issue in the case; (3) the evidence is logically relevant to
    prove this issue for a reason other than criminal propensity; and (4) the prejudicial
    impact of the evidence does not substantially outweigh its probative value. See
    Legette v. United States, 
    69 A.3d 373
    , 379 (D.C. 2013) (internal quotations
    omitted).
    There is clear and convincing evidence that appellant Jenkins committed the
    January 13 and January 16 robberies because Mr. Walls recognized appellant
    Jenkins on both occasions, the two robberies happened within three days of each
    other in an area appellant Jenkins “hung out” in, and Mr. Walls’ stolen prescription
    pill bottle was found inside an apartment building appellant Jenkins frequented.
    Evidence of each robbery is also directed toward the genuine and material issue of
    contested fact in the case, whether appellant Jenkins was misidentified as the
    perpetrator of the robberies. While evidence of the robberies could not be admitted
    to show appellant Jenkins’ propensity to rob, the evidence would have been
    admissible in separate trials as relevant to show, inter alia, identity of the
    perpetrator of the robberies. See Legette, 
    69 A.3d at 379
     (quoting Drew v. United
    States, 
    331 F.2d 85
    , 90 (D.C. Cir. 1964)).
    44
    Here, appellant Jenkins disputed he was the one who robbed Mr. Walls in
    both incidents. However, because the robberies were committed within three days
    of each other, in the same general location, and involved the same victim, the
    evidence of each robbery was admissible to prove identity. See, e.g., Coleman v.
    United States, 
    619 A.2d 40
    , 44-45 (D.C. 1993) (finding evidence of robberies
    occurring within a two-day period at similar locations in close proximity to each
    other was mutually admissible to prove identity because “[t]here need only be
    enough points of similarity in the combination of circumstances to make it
    reasonably probable that the same person committed all of the offenses”). Finally,
    the prejudicial impact of admitting evidence of both robberies did not substantially
    outweigh the probative value of the evidence. As described above, the trial court
    frequently reminded the jury that the two charges were “separate offenses” and
    should be kept separate during deliberations.      Whatever prejudice may have
    occurred as a result of trying both robbery charges at once did not substantially
    outweigh the probative value of each. Thus, the trial court did not abuse its
    discretion by declining appellant Jenkins’ severance motion.
    VII. Ineffective Assistance of Counsel
    45
    While his direct appeal was pending, appellant Jenkins filed a motion for a
    new trial per 
    D.C. Code § 23-110
     (2012 Repl.) on October 12, 2017, claiming
    ineffective assistance of trial counsel. Specifically, appellant Jenkins took issue
    with the fact that during trial, the government introduced a stipulation that
    appellant Jenkins had been incarcerated between October 4, 2011, and December
    30, 2011. 9 Appellant Jenkins argued that his trial counsel was ineffective both for
    agreeing to the stipulation that appellant Jenkins was previously incarcerated and
    for not asking for a limiting instruction informing the jury that it could not infer
    criminal propensity due to appellant Jenkins’ incarceration. On September 18,
    2018, the trial court denied appellant Jenkins’ § 23-110 motion without a hearing,
    to which appellant Jenkins timely appealed. While we conclude that the trial court
    abused its discretion by failing to hold a § 23-110 hearing, we nonetheless affirm
    on lack of prejudice.
    We review the denial of a § 23-110 motion without a hearing for abuse of
    discretion. See Metts v. United States, 
    877 A.2d 113
    , 119 (D.C. 2005) (internal
    quotation omitted). Normally, “when a § 23-110 motion is filed, the trial court
    should conduct a hearing on the motion.” Lopez v. United States, 
    801 A.2d 39
    , 42
    9
    The stipulation was read to the jury twice because the first time the
    government incorrectly stated that appellant Jenkins had been incarcerated in 2012,
    rather than 2011.
    46
    (D.C. 2002). However, a hearing is not required when “the motion and files and
    records of the case conclusively show that the prisoner is entitled to no relief.”
    
    D.C. Code § 23-110
    (c); see also Bellinger v. United States, 
    127 A.3d 505
    , 515
    (D.C. 2015) (“[I]n reviewing a summary denial, we must be satisfied that under no
    circumstances could the petitioner establish facts warranting relief.”) (internal
    quotation omitted).
    Here, the trial court abused its discretion by addressing the deficiency prong
    of appellant Jenkins’ ineffective assistance of counsel claims without first holding
    a hearing.    The court found trial counsel’s decision to stipulate to appellant
    Jenkins’ period of incarceration “a strategic decision” and that counsel “was able
    to strategically use the stipulation to advance its ultimate defense — that [Mr.]
    Walls mistakenly identified [appellant Jenkins] as his assailant — by
    demonstrating to the jury that [Mr.] Walls was not a reliable witness.” The court
    similarly concluded that trial counsel’s decision not to ask for a limiting instruction
    was a tactical decision that “may have unnecessarily focused the jury’s attention on
    [appellant Jenkins’] prior incarceration . . . .” While these may be reasonable
    conclusions to draw from trial counsel’s actions, there is nothing in the record from
    trial counsel himself, either in the transcripts or in a post-trial affidavit, confirming
    he was making his choices for tactical reasons. Absent such evidence from the
    47
    record, “[t]he trial court erred when it repeatedly explained away trial counsel’s
    inaction as ‘trial tactics’ without a sufficient foundation for doing so . . . .”
    (James) Woodard v. United States, 
    719 A.2d 966
    , 969 (D.C. 1998); see also
    (Wayne) Gray v. United States, 
    617 A.2d 521
    , 524 (D.C. 1992) (“At the very least
    … the trial court should have taken testimony from [the appellant’s] trial counsel
    . . . .” before concluding trial counsel’s failure to investigate a witness was a
    reasonable tactical decision); Alexander v. United States, 
    409 A.2d 618
    , 620-21
    (D.C. 1979) (“The judge below could not have concluded on the limited record
    before him that counsel’s failure to raise the defense was a tactical decision . . .
    [t]here may indeed have been a valid tactical reason for not pursuing the insanity
    defense . . . . But on the record in the trial court, one is not able to conclude with
    reasonable certainty what motivated defense counsel to act as he did, and to
    determine whether his actions amounted to ineffective assistance of counsel.”)
    (internal citations omitted).
    Despite the trial court’s abuse of discretion, reversal is not required here
    because we are satisfied that appellant Jenkins did not suffer prejudice that would
    have resulted in a different outcome and thus, a remand for a hearing is not
    warranted. See Clark v. United States, 
    136 A.3d 334
    , 348 (D.C. 2016) (concluding
    that even though the trial court abused its discretion by not holding a hearing on
    48
    certain deficiency claims, because the appellant could not show prejudice, “any
    need for a hearing on the deficiency allegations is now moot”). To prevail on an
    ineffective assistance claim, a defendant “must demonstrate both that his counsel’s
    performance was constitutionally deficient, and that the deficient performance
    prejudiced his defense.” Dorsey v. United States, 
    225 A.3d 724
    , 727 (D.C. 2020)
    (internal quotations omitted). “To demonstrate prejudice, an appellant must show
    ‘a reasonable probability that, but for counsel’s unprofessional errors, the result of
    the proceeding would have been different.’” Clark, 136 A.3d at 341 (quoting
    Strickland v. Washington, 
    466 U.S. 668
    , 694 (1984)). Even if appellant Jenkins’
    trial counsel was deficient for stipulating to appellant Jenkins’ previous
    incarceration and not asking for a propensity instruction, an issue we do not decide
    here,10 appellant Jenkins was not prejudiced because the outcome of the trial would
    have been the same regardless of these potential deficiencies. First, the jury heard
    testimony that Mr. Walls’ pill bottle, which was inside Mr. Walls’ jacket
    taken during the assault, was found in an apartment appellant Jenkins frequented.
    Second, Mr. Walls and Mr. Henderson frequently saw appellant Jenkins outside
    the building, and thus, as discussed above, a jury could more reasonably credit
    10
    See (Reynard) Woodard v. United States, 
    738 A.2d 254
    , 259 (D.C. 1999)
    (“Like the trial court, however, we do not decide this [deficiency] issue because we
    conclude that Woodard was not prejudiced by defense counsel’s failure to consult
    with him before requesting jury instructions on second-degree murder and
    manslaughter.”).
    49
    their identifications of Jenkins.     Third, only defense counsel brought up the
    stipulation to impeach Mr. Walls’ credibility; the government did not try and make
    any improper propensity argument (nor did the jury even know why appellant
    Jenkins had previously been incarcerated).         If anything, taking away defense
    counsel’s chance to attack Mr. Walls’ recollection of constantly seeing appellant
    Jenkins because he was in jail might have made the government’s job easier,
    because there was one fewer seed of doubt about Mr. Walls’ credibility in the
    jury’s mind. On this record, there is no reasonable probability that the stipulation
    and lack of jury instruction would have prevented appellant Jenkins’ convictions
    for assault and robbery.      Thus, appellant Jenkins did not suffer Strickland
    prejudice, and we affirm the trial court’s denial of his § 23-110 motion.
    VIII. Conclusion
    We reverse appellant Jenkins’ conviction of felony assault and remand the
    case for an entry of conviction on the offense of simple assault and for
    resentencing. On the remaining issues raised by appellants, we affirm.
    It is so ordered.
