    Before GLICKMAN and FISHER, Associate Judges, and REID, Senior Judge.
    2
    REID, Senior Judge: These appeals arise from the indictment of nine men on
    multiple felony charges relating to shootings, assaults, and murders that occurred in
    the Benning Terrace housing complex in the Southeast quadrant of the District of
    Columbia from 2009 to 2011.1 Appellants Marcellus McCray, Lamonte Henson,
    Antonio Fortson and Timothy Parker were tried together by a jury presided over by
    the Honorable Henry F. Greene.2 At the conclusion of the trial, which lasted about
    two months, they were convicted of some of the charges.3 They present numerous
    arguments on appeal:     (1) Mr. Fortson argues that the trial court abused its
    1
    The charges involving all or some of the nine men included conspiracy to
    assault and murder, in violation of 
    D.C. Code § 22-1805
     (a) (2012 Repl.);
    first-degree murder while armed (premeditated), in violation of §§ 22-2101 and
    -4502; second-degree murder while armed, in violation of §§ 22-2103 and -4502;
    assault with intent to kill while armed (AWIKWA), in violation of §§ 22-401 and
    -4502; possession of a firearm during a crime of violence or dangerous offense
    (PFCV), in violation of § 22-4504 (b); carrying a pistol without a license (CPWL), in
    violation of § 22-4504 (a); and unlawful possession of a firearm – prior felony
    (UPF), in violation of § 22-4503 (a).
    2
    Curtis (a/k/a Kurtis) Faison and Lamont Thomas were tried with
    appellants, but they entered guilty pleas during trial. Three other men, Kevin
    Magruder, Deandre Mungo, and Anthony Hebron were tried separately.
    3
    The jury found Mr. McCray guilty of AWIKWA, the lesser-included
    offense of voluntary manslaughter, PFCV and CPWL; Mr. Henson guilty of CPWL;
    Mr. Fortson guilty of the lesser-included offense of voluntary manslaughter, the
    lesser-included offense of assault with a dangerous weapon (ADW), PFCV, and
    CPWL; and Mr. Parker guilty of the lesser-included offense of voluntary
    manslaughter, PFCV, CPWL, and UPF.
    3
    discretion by permitting a juror who violated the court‘s instructions to continue
    serving, thus denying Mr. Fortson his Sixth Amendment right to an impartial jury;
    (2) Messrs. McCray, Fortson, and Parker claim error pertaining to the trial court‘s
    urban gun battle and aiding and abetting instructions; (3) Messrs. McCray, Henson,
    and Fortson contend that the evidence was insufficient to convict them of specified
    charges; (4) Mr. McCray and Mr. Parker contend that the trial court abused its
    discretion by curtailing their efforts to obtain mental health information in order to
    impeach a key government witness and former codefendant; and (5) appellants make
    several other arguments, some of which we treat summarily.
    For the reasons stated below, we (1) discern no abuse of discretion with
    respect to Judge Greene‘s approach to and resolution of the alleged juror misconduct
    issue; (2) conclude that (a) the trial court‘s urban gun battle and aiding and abetting
    instructions did not result in a constructive amendment of the indictment, and (b)
    there was no prejudice to the defendants resulting from these instructions, and
    hence, any error would be harmless; (3) hold that the evidence was sufficient to
    convict Mr. McCray of counts 8 and 9; (4) hold that the evidence was sufficient to
    convict Mr. Fortson, Mr. McCray, and Mr. Parker, as co-principals, of the
    lesser-included offense of voluntary manslaughter (count 10), as well as the related
    4
    weapons charges; (5) reverse Mr. Henson‘s CPWL conviction (count 16) on
    insufficiency of evidence grounds; (6) conclude that the government‘s evidence was
    sufficient to convict Mr. Fortson of ADW (counts 5 and 6); (7) hold that the
    government proved by a preponderance of the evidence that the statements in Mr.
    McCray‘s videotaped confession were voluntary; (8) conclude that the trial court did
    not abuse its discretion in denying Mr. McCray‘s severance motion; (9) reject Mr.
    Parker‘s contention that the trial court abused its discretion in permitting Ms. Rajah
    to testify on redirect that she relocated, in part, because of her fear of Mr. Parker, and
    we also reject Mr. Parker‘s merger arguments; (10) remand Mr. Parker‘s and Mr.
    McCray‘s cases to the trial court solely to provide them with an opportunity to show,
    at a hearing and through expert opinion, whether at the time of his trial testimony
    Mr. Faison‘s mental disabilities seriously impacted his credibility; and (11)
    conclude that appellants‘ other contentions are not persuasive.

    FACTUAL SUMMARY
    The government presented evidence of shootings4 in April and May 2010,
    and other months, in part of the Benning Terrace housing complex.5 The shootings
    took place in two areas: (1) an area known as ―the circle‖ where several low-rise
    apartment buildings are located to the north of and on the west and east sides of 46th
    Place, and (2) an area known as ―the Avenue‖ because it is located near Alabama
    Avenue where other housing units are located.
    4
    Since the jury acquitted all of the appellants on the conspiracy to murder
    charge and could not reach a verdict on the conspiracy to assault charge, we do not
    set forth detailed evidence presented by the government concerning the alleged
    conspiracy.
    5
    The housing complex consists of apartment buildings, row houses, and
    common areas. The boundaries of part of the Benning Terrace housing complex
    include 46th Street which curves around part of the complex; F Street towards the
    northern part of the complex; G Street towards the southern part of the complex; and
    46th Place which is perpendicular to G Street and which ends in a circle in the
    northern part of the complex. Alabama Avenue is partly parallel to 46th Street and
    crosses both F Street and G Street. In front of the circle, which has space for parked
    cars, are interconnected low-rise apartment buildings – 600, 602, and 604 46th
    Place. Forty-Sixth Place also separates interconnected buildings – 601, 603 and
    605, located on one side of 46th Place, and interconnected buildings – 610, 612 and
    620, situated on the other side of 46th Place. There is also space for parking outside
    of one end of building 605, and there are mailboxes in the courtyard at the other end
    of building 605. Garbage dumpsters are located on the other side of building 605.
    6
    The shootings arose from a ―beef‖ or feud between young men who identified
    with ―the circle‖ and others who were linked to ―the Avenue.‖ The feud grew out
    of drug transactions in the circle area of the housing complex. Jovan Clay, who at
    one time lived in the 620 building on 46th Place, testified that the feud occurred
    because young men from the Avenue were ―trying to come in the circle and rob
    people in the circle.‖ 6 Joshua Johnson, who lived on F Street, near Alabama
    Avenue, but who hung around the circle, stated that ―there was a dispute between
    individuals who hung over on the Avenue and individuals who hung in the circle.‖
    The feud between the young men from the circle and those from the Avenue
    involved the use of guns. As Mr. Clay put it, the circle and Avenue men were
    6
    Several of the government‘s witnesses were given immunity, executed
    cooperation agreements with the government, entered guilty pleas to felonies,
    served time for past convictions, or were incarcerated for trying to flee before the
    trial in this matter. Jovan Clay had a plea agreement, and entered guilty pleas to
    second-degree murder while armed of Michael Wilson, assault with intent to rob
    Mekal Jones, and conspiracy to distribute narcotics and possess firearms in the
    circle. Angelo Wages was given limited immunity and was incarcerated at the time
    of his testimony because he had attempted to flee after receiving a subpoena to
    appear as a witness in this case. At the time of his testimony, Joshua Johnson was
    incarcerated for a probation or parole violation; had served time for armed
    carjacking, and had entered a guilty plea to a felon in possession of a firearm offense
    but had not yet been sentenced; he signed a cooperation agreement with the
    government. Curtis Faison signed a cooperation agreement with the government;
    entered a guilty plea to a charge of second-degree murder while armed of Melvin
    White; conspiracy, obstruction of justice, and assault (of a correctional officer); and
    he had been convicted previously of various crimes, including second-degree
    burglary.
    7
    ―trying to kill each other.‖ According to Mr. Johnson, Mr. Fortson once said
    ―bi**h a*s nig**s from the Avenue, they always . . . think they‘re going to come out
    here and do what they want and we[‘]re not going to do nothing to them.‖ Mr.
    Johnson also heard Mr. McCray say, ―he kill[ed] when he was over there [the
    Avenue], some bi**h a*s nig**s.‖
    The first shooting that was the subject of the case against appellants
    concerned Melvin White who was shot and killed on April 10, 2010. After the
    government presented compelling evidence that Curtis Faison shot and fatally
    wounded Mr. White, Mr. Faison entered a guilty plea to various charges, including
    the murder of Mr. White.
    The second and third shootings pertaining to the case against appellants took
    place on May 30, 2010. Linwood Hopkins, who lived on the third floor in the 610
    building on 46th Place with his wife and their children, testified that on May 30 he
    and his family returned from a cookout around 7 p.m. That night he heard shots
    coming from the back of his building towards Alabama Avenue. He looked out of a
    window and saw someone running towards some dumpsters. He went to his
    balcony at the front of his apartment to alert people who were having a cookout to go
    8
    inside. He heard more shots and saw a man run from the side of his building while
    shooting; the man ran behind building 600. Mr. Hopkins also witnessed a man
    dropping in front of his building, and he heard ―a lot of shooting‖; it sounded as
    though two or three guns were being fired.
    Although he could not remember the exact date on which he saw and heard
    shootings at the Benning Terrace complex, Carl Brown, a maintenance worker for
    the District of Columbia Housing Authority, testified that it was a ―warm day‖ in
    2010. While he was working on a house at 46th Place and G Street, he heard shots
    and saw Lamont Thomas (who entered a guilty plea during trial), Mr. Fortson, and
    about four other men. Mr. Brown got under a truck. Mr. Thomas started shooting;
    he had ―something like‖ ―a 357.‖ Young men walking up G Street were shooting
    back. Mr. Fortson had a small handgun in his hand but Mr. Brown did not see Mr.
    Fortson fire the gun. Mr. Fortson went behind a building on the right side of 46th
    Place, and Mr. Brown heard ―a whole lot of shooting . . . back and forth.‖ Mr.
    Brown testified before the grand jury that following the shooting, Mr. Fortson said
    to him, ―[my] bad.‖ At trial, Mr. Brown said Mr. Fortson declared, ―[my] bag.‖
    9
    One of the government‘s main witnesses regarding the events of May 30,
    2010, was Angelo Wages. He grew up in Benning Terrace and lived in the 4600
    block of G Street with his mother and sisters. At the time of the May shootings he
    had lived alone in a first floor apartment in building 620 on 46th Place for about
    three years. He was a reluctant trial witness and the prosecutor often used his grand
    jury transcripts of September 10, 2010, and September 24, 2010, to refresh his
    recollection or to impeach him about details relating to the events of May 30 and the
    actions of the appellants.
    Mr. Wages recognized all of the appellants at trial. He admitted having a
    conversation with Mr. Fortson about keeping guns at his (Mr. Wages‘s) apartment.
    He had seen Mr. Parker around Benning Terrace with Mr. Buckner, a young man
    who lived in the circle part of Benning Terrace and who was killed late on the night
    of May 30.     That night, Mr. Wages observed several young men with guns,
    including Mr. Henson, Mr. Thomas, Mr. Mungo, and Mr. Magruder. Earlier on
    May 30, before Mr. Buckner was shot, Mr. Wages heard gunshots and went outside.
    Mr. Thomas, Mr. Magruder and someone else were engaged in conversation. Mr.
    Thomas said, ―They‘re shooting at the Avenue.‖ The day after the May 30th
    shootings, Mr. Wages spoke with Mr. McCray who said that before the later
    10
    shootings on May 30, he had been ―shooting at the Avenue boys.‖ The shooting
    was coming from the ―back cut‖ near building 620. Mr. McCray said he was
    shooting with Mr. Mungo and Mr. Mungo indicated that he was shooting at the
    Avenue.
    Following the first shootings on May 30, Mr. Wages later sat with Mr.
    Buckner and another person at the mailboxes, located near buildings 601, 603 and
    605. Mr. Wages heard shots and got up to go into building 601. Mr. Buckner was
    behind him, carrying a chair and a wine bottle. Mr. Buckner never made it inside
    building 601. Mr. Wages saw Mr. Buckner get shot and fall to the ground. Mr.
    Buckner got up and staggered; he was ―leaning forward, like he couldn‘t quite stand
    up straight.‖ Mr. Wages watched Mr. Buckner from a window on the second floor
    of building 601 where he could see the mailboxes and half of the circle. Mr.
    Henson and Mr. Fortson were shooting in the courtyard between buildings 601, 603
    and 605. They also had shot in a grassy area between buildings 600 and 601, near a
    playground. Mr. Henson and Mr. Fortson were ―shooting across the circle to the
    cut between [buildings] 604 and 610.‖ They fired ―over eight‖ shots in the grassy
    area between buildings 600 and 601, and ―four shots‖ into the grassy area between
    buildings 604 and 610. At trial, Mr. Wages denied being able to see Mr. Henson‘s
    11
    and Mr. Fortson‘s faces, but he was impeached with his grand jury testimony stating
    that when he looked out of the window he saw their faces. On the night of May 30,
    Mr. Wages had a conversation with Mr. Henson and Mr. Fortson about what had
    happened. Mr. Henson said ―he was putting in work,‖ and Mr. Fortson ―said he
    was putting in work, meaning shooting back.‖
    Mr. Clay was another government witness. He described his relationship
    with Mr. Henson as that of a brother. The two men lived together in 2008 and 2009.
    Between July 4, 2009, and the time of his [Mr. Clay‘s] arrest in 2010, including
    April and May 2010, Mr. Clay ―always‖ saw Mr. Henson with guns, ―different
    type[s] of guns.‖ These included Glock .40 caliber and .45 caliber ―handguns‖ with
    barrels between 9 and 10 inches in size, as well as guns with bigger barrels of 9 to 11
    inches. He never saw Mr. Henson with ―a big rifle or shotgun.‖
    Mr. Clay witnessed shootings on May 30, 2010. Early in the morning and
    before the murder of Mr. Buckner, Mr. Clay and Mr. Fortson were outside. A man
    named Junior walked through a cut below building 620. Mr. Fortson ―was coming
    through the cut by the mailbox‖ near building 605 and Mr. Fortson ―started shooting
    at [Junior] [a]nd he ran back on the [A]venue.‖ Later, Mr. Clay walked around the
    12
    circle and stood, with another man, by the mailboxes near the courtyard of building
    605. He saw Mr. Buckner sitting in a little chair by the mailboxes; Mr. Fortson was
    by the mailboxes. Mr. Clay heard shots ―coming from off the Avenue.‖ Before
    hearing additional shots he saw Mr. McCray, Mr. Hebron and Mr. Mungo walk by
    the mailboxes towards the parking lot where dumpsters were located. A resident,
    Shunedia (―Nita‖) Rajah, stepped out on her balcony. She told everyone to run
    because people were about to start shooting. Mr. Clay saw three men; shots were
    fired towards the back hill. He ran to the second floor of building 605 and looked
    out of the window. A person from the Avenue came out of a cut shooting towards
    the parking lot by building 605. Mr. Hebron shot back. Mr. Mungo and Mr.
    McCray stood in the middle of the parking lot near dumpsters, taking turns shooting
    back with a Glock that had a 30-shot clip in it.7 Mr. Mungo proceeded down the
    sidewalk towards G Street while Mr. McCray continued to shoot before following
    Mr. Mungo. Mr. Fortson went into one of the buildings; he had his Glock .40, gave
    it to Kevin Johnson and asked him to ―put this up.‖ After the shooting stopped, Mr.
    Clay exited building 605 and noticed Mr. Buckner on the ground. Later that night,
    Mr. Clay had conversations with Mr. Hebron and Mr. McCray and they both
    7
    Around the time of Mr. Buckner‘s murder, Mr. Johnson saw Mr. McCray
    with a gun before and after Mr. Buckner was shot.
    13
    commented on the earlier shootings saying, ―Man they always come down here.
    Why we can‘t go up there first?‖
    Toni Hopkins, the wife of Linwood Hopkins, and Ms. Rajah testified on
    behalf of the government. Ms. Hopkins was in her bedroom towards the front of
    her apartment on May 30. Ms. Rajah, who lived in the apartment below the
    Hopkins‘ apartment, was with Ms. Hopkins when they heard gunshots which
    appeared to come from the back, near a field. Ms. Rajah went out onto the balcony
    and later Ms. Hopkins took her a phone so she could call 911. Ms. Rajah asked Ms.
    Hopkins, ―Did you hear my door slam,‖ and Ms. Hopkins asked, ―You didn‘t lock
    your door?‖ The next day Ms. Hopkins was in Ms. Rajah‘s apartment when a man
    known as ―Son‖ (Mr. Magruder) came in and asked Ms. Rajah if anyone gave her
    anything. Mr. Magruder told Ms. Hopkins to get up from the couch; he retrieved a
    gun from underneath a cushion. Ms. Rajah ―flicked off‖ and Son ―told her to
    shush‖ and left the apartment.
    Ms. Rajah used to live on the second floor of building 610. When she came
    home on the evening of May 30, 2010, a lot of people were outside having a
    cookout. She went up to visit the Hopkins. During her visit, Mr. Hopkins called
    14
    her to the balcony. She saw Mr. Parker, Mr. Henson, Mr. Clay, kids and neighbors.
    She observed Mr. Parker move from the mailboxes near building 605, cross the
    street and walk towards building 610. He had a rag over the top of his hand, and
    was making the kids and neighbors go inside the building. Ms. Rajah saw and
    heard Mr. Parker shoot a gun once at a man coming up the hill and going around the
    building. Later, he aimed the gun towards a fence. Mr. Parker was shooting –
    ―pow, pow‖ – and then gunshots rang out from the hill between buildings 604 and
    610, by the playground between buildings 600 and 601, and the area around building
    620. She claimed she saw William Spriggs (―Wheetie‖) fire the fatal shot that
    killed Mr. Buckner. The day after the shootings, Ms. Hopkins was in Ms. Rajah‘s
    apartment when Mr. Magruder came and asked whether Mr. Parker had left anything
    in her apartment. She replied, no, but also indicated that her door was unlocked and
    she had been upstairs. Mr. Magruder removed a gun from under a couch pillow and
    a bullet. Ms. Rajah had not seen the gun before; it was a semi-automatic weapon.8
    8
    During June 2010, Ms. Rajah looked out of her kitchen window and saw
    Mr. Henson in the grassy area behind her building. He was shooting into an area by
    houses off G Street. However, she could not see the type of gun that Mr. Henson
    held. She went to her living room and saw him jump over the balcony into Mr.
    Wages‘s house. When he came out of the building, he had on a different shirt. She
    also saw Mr. Mungo and Mr. McCray running from the playground by buildings 600
    and 601 towards her building. She heard gunshots and saw Mr. Mungo tucking
    something in his pants that looked like a gun.
    15
    In June 2010, Ms. Rajah looked out of her kitchen window and saw Mr. Henson
    shooting a gun towards houses off of G Street, but she could not see the kind of gun
    that he possessed.    On cross-examination, Ms. Rajah acknowledged that she
    received a voucher for housing paid for by the government after she relocated to a
    different address. On redirect examination, she testified that she left the Benning
    Terrace complex because she ―was scared‖ and afraid of Mr. Spriggs, Mr. Parker,
    and Mr. Magruder.
    During his testimony after he entered guilty pleas to certain charges, Mr.
    Faison implicated both Mr. Parker and Mr. McCray. On the night that Mr. Buckner
    was killed, Mr. Parker told Mr. Faison that he was in the area of the mailboxes
    chilling, and that he grabbed a gun hidden underneath the steps at the 605 building.
    Mr. Parker said he ―crossed the circle and had his hand and the gun covered with a
    scarf of some sort.‖ Mr. Parker ―started pushing people into the building‖ ―when he
    saw William Spriggs or Wheetie come out the back hill.‖ Mr. Parker ―shot once but
    the gun jammed.‖ He went inside the building, fixed the jam ―[a]nd then he came
    back out shooting.‖ During a conversation with Mr. Parker in March 2011, for
    which Mr. Fortson, Mr. Henson, Mr. Thomas and Mr. McCray were present, Mr.
    Parker and others sent Mr. Hebron over to the Avenue and ―they did a bulls**t job.‖
    16
    Mr. Fortson said he was involved in sending Mr. Hebron ―and them‖ over to the
    Avenue to shoot prior to the shootout that ended with Mr. Buckner‘s fatal shooting,
    and that he was over by the mailboxes and shot at someone by the playground and
    back towards the hill. Mr. McCray asserted that prior to the shootout, he went over
    to the Avenue and shot with Mr. Hebron and Mr. Mungo.9
    9
    Defense counsel conducted rigorous cross-examination of Mr. Faison,
    seeking to cast doubt on his character and truthfulness, and attempting to show that
    he was courting favor with the government. In response to cross-examination by
    Mr. Parker‘s counsel, Mr. Faison admitted that he killed Melvin White, would have
    killed Mr. Wages had he (Mr. Faison) been kicked out of Mr. Wages‘s home, had
    pulled a gun on many people, tried to prevent government witnesses from coming to
    court to testify at his trial, obstructed justice, was testifying because he wanted
    leniency from the government, the government dropped an ADW charge against
    him for throwing a chair at a correctional officer, had been locked up since age 10
    for stealing cars and robbing people, and had stabbed someone in the head three or
    four times while he was incarcerated at the D.C. Jail. Counsel for Mr. Fortson and
    counsel for Mr. McCray both asked about Mr. Faison‘s request for their assistance at
    trial, which he denied. Specifically, Mr. Faison denied asking counsel for Mr.
    Fortson whether there were any holes in the government‘s conspiracy case, being
    told that the government had failed to put all of the defendants together, and then
    seeking to put them together during his testimony. Counsel for Mr. Fortson also
    established that Mr. Faison had pled guilty to second-degree murder but not to the
    PFCV charge. In response to a question from Mr. McCray‘s lawyer, Mr. Faison
    denied knowing an inmate at the D.C. Jail named Robert Golden. However, he
    admitted to the prosecutor on redirect examination that he not only received a letter
    at the jail from Mr. Golden, but also that Mr. Golden had watched him (Mr. Faison)
    grow up.
    17
    In addition to testimony from fact witnesses about the events in Benning
    Terrace in May and June 2010, the government presented ballistics evidence, and
    the testimony of Dr. Marie-Lydie Pierre-Louis, the District‘s Chief Medical
    Examiner at the time of Mr. Buckner‘s murder. Metropolitan Police Department
    (―MPD‖) officers and technicians collected shell casings from the scene and an
    independent firearms technician linked the casings to weapons fired by appellants
    during the shootings on May 30, 2010.10 Dr. Pierre-Louis performed the autopsy of
    Mr. Buckner and stated that the cause of death was a gunshot to the head and neck.
    She ―recovered a copper-jacketed bullet‖ and two small fragments from Mr.
    10
    MPD mobile crime technician, Petheria McIver, responded to the 600
    block of 46th Place around 10:30 or 11:00 p.m. on May 30, 2010. She located shell
    casings, a whole bullet and a bullet fragment by building 610. MPD Officer
    Edward Roach, a crime scene investigator, collected shell casings in an area across
    from buildings 610, 612 and 620. John Holder, MPD evidence technician,
    re-canvassed the area early on the morning of May 31, 2010, and recovered cartridge
    casings in the parking lot near dumpsters and near the mailboxes. Robert Freese, an
    independent firearm examiner, analyzed the ballistics evidence in an effort to
    identify the guns that fired the bullets and cartridge casings. He determined, in part,
    that the shell casings recovered from the scene were fired from a .380 semiautomatic
    pistol, a .40 caliber semiautomatic firearm, a Glock 9-millimeter Lugar Model 19
    pistol, and a Talon 9-millimeter semiautomatic pistol. The evidence was not clear
    as to the weapon that fired the bullet removed from Mr. Buckner‘s body. In
    addition, the government introduced and the trial court admitted Exhibit 582
    showing the location of color-coded shell casings recovered from around the front of
    building 610 that were fired by the same .40 caliber firearm, casings from the area of
    the mailboxes fired by the same 9-millimeter weapon, and casings around building
    605 fired by the same (but two different) 9-millimeter weapons. Exhibit 582 also
    reflected the recovery of .380 shells found on the Avenue.
    18
    Buckner‘s body. The independent firearm examiner testified that the .38 class
    copper-jacketed bullet removed from Mr. Buckner was ―not consistent‖ with any of
    the four firearms (two 9-millimeter Glock 19 pistols, a .40 CZ semiautomatic pistol,
    and a Talon 9-millimeter pistol) introduced by the government. A .38 class would
    include a 9-millimeter, a .38 special and a .357 magnum firearm.
    ANALYSIS
    Alleged Juror Misconduct
    Mr. Fortson contends that the trial court abused its discretion by permitting a
    juror who violated the court‘s instructions to continue serving without proper
    investigation as to ―whether that juror really had pre-decided the case at the outset of
    the trial, and possibly spoken about her decision with even more jurors,‖ thus
    denying his Sixth Amendment right to an impartial jury.
    19
    The Factual Context
    We first set forth the factual context for this issue. Before the jurors retired
    to begin deliberations on the afternoon of Tuesday, July 3, 2012, Judge Greene
    cautioned them that, ―It is unwise for any juror on entering the jury room to voice an
    emphatic expression of his or her opinion on these cases or to announce a
    determination to stand only for a certain verdict as to a particular count or a
    particular defendant.‖ He further instructed the jurors, ―To each of you I would say
    that you must decide these cases for yourself, but you should do so only after
    discussing them with your fellow jurors and you should not hesitate to change your
    opinion if you become convinced that it‘s in error.‖
    Judge Greene received four notes on Thursday, July 12, 2012, all from the
    foreperson – the first at 11:57 a.m., the second at 1:29 p.m. and the last two at 3:15
    p.m. The first note concerned the conspiracy counts, which are not at issue in this
    appeal; the second note said, ―We would like to see gun #6,‖ and that note was a
    follow-up to the jury‘s July 5 request to see all of the guns.11 The third note stated,
    11
    Judge Greene instructed the jury about the conspiracy question and the
    request to see all of the guns around 12:30 p.m. The court initially believed that
    (continued…)
    20
    ―I would like to have a private conversation with Judge Greene about an important
    matter concerning a specific juror who has had their mind made up on the first
    week.‖ The fourth note read, ―If we are deadlocked on one count, would that
    negate all the rest of the charges and how long does it have to take to deliberate if we
    still can‘t come to a conclusion.‖
    Counsel and Judge Greene initially disagreed about when and how to respond
    to the jury about the third and fourth notes. The judge proposed that given the 4:00
    p.m. hour, he simply tell the jury that he was not prepared to respond at that time and
    excuse the jury for the weekend. The prosecutor disagreed, noting that the jury had
    been deliberating only for ―maybe four and a half hours a day,‖ and that ―[t]here‘s
    clearly a problem.‖     She opposed a three-day delay without obtaining some
    ―clarification about the note with a specific juror who has their mind made up.‖ If
    the juror both had his or her mind made up and was refusing to deliberate, the
    prosecutor argued ―that that would require us to take additional steps‖ and an
    (…continued)
    only four guns had been admitted into evidence. After discovering that five had
    been admitted, five were shown to the jury. But a sixth gun had been admitted and
    the court asked the jury to inform it if it needed to see the sixth gun. The jury later
    requested gun #6, and that gun also was shown to the jury.
    21
    alternate might have to be designated to deliberate. One defense counsel agreed
    with Judge Greene‘s proposal.
    Judge Greene declined to follow the government‘s suggestion, saying ―the
    worst thing one can do here is act precipitously, and it may be the worst thing one
    can do is to get clarification,‖ ―or to isolate a juror early on in this process.‖ He
    observed that cases in which the verdict was sustained ―tend to be [those] where
    judges acted cautiously and did everything they could to avoid isolating jurors and
    avoid anything that would look like coercing them.‖         He also referenced the
    significance of the fourth note concerning a deadlock. After further argument from
    the prosecutor and following views of other defense counsel in favor of Judge
    Greene‘s proposal, the judge decided to follow his proposal. He explained to the
    jury that he needed to discuss the notes with counsel. The judge also informed the
    jurors that he appreciated their service, and he conveyed his understanding that the
    process was not ―easy‖ and that is why jurors are ―encouraged . . . to express [their]
    own views . . . [and] to try to deal with each other in a civil and courteous and
    respectful fashion.‖ He complimented the jurors for doing that, and dismissed them
    until Monday morning.
    22
    After dismissing the jury, Judge Greene informed counsel about his
    preliminary thoughts on the notes, as well as case law that he considered helpful.
    On Monday morning, he pondered whether the third note meant that the juror had
    his or her mind made up since the first week of trial or the first week of deliberations.
    Following discussion with counsel, he brought the foreperson in for the purpose of
    answering that question. Judge Greene first informed the foreperson that he could
    never have a private conversation with any juror, and then posed the question, to
    which the foreperson responded, ―first week of trial.‖            The judge sent the
    foreperson back to the deliberation room with instructions not to discuss the matter
    with the other jurors.
    Judge Greene informed counsel that he wanted to find out what is meant by
    ―had her mind made up.‖ However, he regarded the foreperson as ―somebody
    [who] could talk expansively,‖ and thus, the judge wanted to pose ―very specific
    questions‖ to her. Counsel for Mr. Fortson advocated identifying the juror whose
    mind had been made up and then conducting a voir dire of that juror. He also
    thought that in order to determine ―taint,‖ the court should conduct a voir dire of the
    entire jury panel to determine whether the other jurors ―agree[d] with the
    foreperson‘s assessment that this juror is not deliberating.‖ Judge Greene and
    23
    Counsel for Mr. Fortson continued to exchange views about how to proceed. The
    judge agreed with Counsel that they needed to determine whether the foreperson‘s
    statement was ―based on a hunch,‖ although he suspected that it was not. But Judge
    Greene again expressed concern that the foreperson was ―a fairly voluble
    foreperson,‖ and hence, he ―want[ed] to be very careful about what additional things
    he asked her.‖12
    Following a caucus of defense counsel, there were further discussions
    between counsel and the court. Counsel for Mr. Fortson particularly wanted to
    know whether other jurors were present when the juror in question spoke with the
    foreperson about his or her mind being made up. Judge Greene made it clear that he
    would not ask the foreperson to identify the juror. He summarized the types of
    questions he might ask the foreperson, and the prosecutor thought they were ―way
    too much.‖ After further reflection, Judge Greene remarked that ―everybody agrees
    that we ought to find out . . . whether this was a one-time remark or whether it has
    12
    Judge Greene also considered the views of the prosecutor, and he shared
    with counsel his discussion with a colleague whom he respects. Judge Greene and
    the colleague both agreed that they should avoid ―singling out a juror, because when
    you start singling out a jur[or] you move quickly into the territory of where there is
    some alleged coercion.‖
    24
    been repeated, and whether [the foreperson] has only discussed it with the juror or
    with all of the jurors.‖ Counsel for Mr. Fortson concurred, and added, ―In terms of
    identifying the particular juror, obviously as the court said, that would be a final step
    in the process. And I am not, if the [c]ourt believes that taking this process
    incrementally we need to go there, and that is fine.‖
    Judge Greene summoned the foreperson, instructed her to respond only to the
    questions posed, and after a preliminary question asked when the foreperson learned
    that ―the juror had their mind made up.‖ From the options provided by the judge,
    the foreperson said, ―During the trial.‖ With additional questioning Judge Greene
    learned that the foreperson spoke with the juror ―[a]round the first week of the trial,‖
    and the juror spoke only to the foreperson and not in the presence of all the jurors.
    The juror spoke with the foreperson ―[o]nly one time.‖
    While the foreperson waited in the back of the courtroom, Judge Greene
    conversed with counsel about whether additional inquiry should be made. Those
    participating in the conversation as to whether, and if so what, additional questions
    should be posed to the foreperson were counsel for Mr. Henson and Parker, and the
    prosecutor. After narrowing the follow-up questions to one, Judge Greene decided
    25
    to accept the prosecutor‘s suggestion that instead of asking the foreperson whether
    she spoke with any other jurors, he instruct the foreperson not to discuss the matter
    with other jurors. Counsel for Mr. Henson, the only defense counsel to speak on
    this approach stated, ―That will probably be good, because it will nip it in the bud.‖
    Judge Greene brought the foreperson forward and gave instructions not to discuss
    the matter with other jurors, and told the foreperson that the court would speak with
    the jury panel. Neither counsel for Mr. Fortson, nor any other defense counsel,
    raised an objection.
    When the jurors assembled, Judge Greene gave a lengthy charge, stating in
    part:
    One question raised the issue whether if the jury finds
    itself unable to reach a decision on one count does that
    mean the jury cannot continue to deliberate and reach
    verdicts on other counts. The short answer to that
    question is no.
    In other words, if the jury finds itself unable to reach a
    verdict as to one defendant on one count, the jury still may
    proceed to consider any remaining defendants charged
    under that count, if they are charged, and reach an
    individual verdict of guilty or not guilty as to each of those
    defendants.
    Likewise, similarly, if the jury finds itself unable to reach
    a verdict as to all of the defendants charged under a
    26
    particular count the jury may proceed to consider all of the
    other counts in which defendants are charged, and reach
    individual verdicts of guilty or not guilty as to each
    defendant on each remaining count with which that
    defendant is charged . . . .
    [A] second question asked was how long the jury must
    deliberate if it cannot reach verdicts as to every defendant
    on every count, with which that defendant is charged. In
    response to that question, let me say as I think I may have
    told you earlier, there is no prescribed time for
    deliberations in any case. And, I am inclined to give the
    jury as much time as it needs to reach verdicts.
    It is not my intention to force or coerce the jury to reach a
    verdict, but on this topic I think I should note that this has
    been a very long trial, close to two months. And longer
    than almost any other trials we have in Superior Court in
    the course of an average year.
    I don‘t know exact numbers here, but I believe the jury has
    heard over 60 witnesses, it has had in excess of 500
    exhibits to consider during its deliberations. And, as I
    reviewed the verdict form, before preparing these
    remarks, I counted at least 27 verdicts that you must
    consider when you add up all the verdicts requested on the
    verdict forms for all of the four defendants . . . . Thus, I
    would expect it to take a considerable amount of time to
    reach a resolution of the matters before you.
    My best judgment is that up to this point I think you have
    been deliberating about five and a half days when you add
    . . . all the time together, which is certainly not an unusual
    length of time in cases of this length and complexity.
    So, in sum, in response to the second question, I am going
    to ask that you deliberate further in these cases, and give
    them your best efforts, as I am sure you have been doing.
    27
    Now, before I let you return to the jury room though, I
    have to address the third question I received indicating
    concern about what happens if jurors make up their minds
    about issues in the case, either before all of the evidence,
    and testimony is in, or before jurors have heard the views
    of all their colleagues on the jury, and thus may not have
    been fully involved in the deliberation process up until
    now.
    As I told you, in my preliminary instruction two months
    ago, . . . it is important during trial that each of you keep an
    open mind during the entire trial, and that each of you not
    decide any issue in this case until the entire case is
    submitted to you with my final instructions.
    As I told you in my final instructions it is unwise for any
    juror at the outset of deliberations to voice an emphatic
    expression of his or her opinion on these cases, or to
    announce a decision or a determination to stand only for a
    certain verdict as to a particular count or a particular
    defendant until you have listened to and discussed the
    views of all of your colleagues on the jury.
    As you left last Thursday, I talked to you a little bit about
    how difficult your job is. I know that jury deliberations
    involve serious issues, and serious views expressed by all
    members of the jury. The views each of you express are
    to be taken seriously and considered seriously. That is
    why I encourage each of you to express your views, and
    listen to each other‘s views and to always speak and listen
    in a courteous, thoughtful manner with respect for civility
    towards one another.
    Bear in mind, that even during deliberations there is no
    verdict on an issue you are deliberating about until all 12
    jurors agree, and each of you are free to change your mind
    at any time from a position you previously had to a new
    28
    position if you wish to and you think, you are convinced
    the new position is the correct one.
    With these thoughts in mind, ladies and gentlemen, I am
    going to ask you to resume your deliberations . . . .
    Now, if any of you feel for any reason that you have not
    been able to, or are not able to follow the instructions I
    have given you, please let me know in a written note, but
    do not discuss any personal concerns you may have in this
    regard with any of the other jurors. You can send me a
    note in writing if you have a concern about whether you
    can follow the instructions I have given you.
    No counsel posed any objection to Judge Greene‘s statements and instructions.
    The Parties’ Arguments
    Mr. Fortson maintains that the trial court failed to conduct a proper
    investigation into ―the circumstances of the offending juror‘s misconduct, and
    whether it may have contributed to others‘ violations of the court‘s instructions.‖
    He claims that the court abused its discretion by simply requiring jurors to let him
    know if they ―were unable to follow the court‘s instructions.‖ The government
    argues that Mr. Fortson‘s claim is subject to plain error review because he [and Mr.
    McCray] failed to object to the court‘s proposed procedure after the second voir dire
    29
    of the jury foreperson. 13      The government contends that, ―In exercising its
    discretion, the trial court hewed closely to this [c]ourt‘s teaching about how to
    handle cases involving a complaint about deadlock and a juror not following the
    law.‖ As a result, the government asserts, the trial court did not ―err[] in deciding
    not to voir dire the jury individually,‖ and Mr. Fortson‘s substantial rights were not
    prejudiced.
    Applicable Legal Standard and Principles
    We are guided by the following legal standard and principles in analyzing the
    juror misconduct issue and the parties‘ arguments. ―The authority to excuse a juror
    during deliberations is to be exercised with caution.‖ Brown v. United States, 
    818 A.2d 179
    , 184-85 (D.C. 2003) (internal quotation marks and citation omitted).
    ―Although the presence of a juror incapable of or unwilling to deliberate and decide
    a case on the evidence undermines the fairness of a trial, excluding a juror at this
    particularly sensitive stage of the trial, presents distinct risks both to the defendant‘s
    13
    The government cites Grant v. United States, 
    85 A.3d 90
    , 99 (D.C. 2014),
    for the proposition that plain error applies because no objection was made after the
    court‘s instruction. We think it unnecessary to resolve the government‘s argument
    as to plain error, given our disposition concerning the trial court‘s handling of the
    alleged juror misconduct issue.
    30
    right to jury unanimity in criminal cases and to the secrecy of jury deliberations —
    the cornerstone of the modern Anglo-American jury system.‖ 
    Id. at 185
     (internal
    quotation marks and citations omitted). Thus, although the trial judge has the
    ―authority to inquire into claims of juror misconduct during deliberations, . . . []he
    must proceed . . . with caution, tact, and respect for the prerogatives of the jury.‖ 
    Id.
    (quoting Shotikare v. United States, 
    779 A.2d 335
    , 345 (D.C. 2001) (internal
    quotation marks omitted)).
    Discussion
    Between Tuesday, July 3 and the morning of Thursday, July 12, Judge Greene
    received only one note from the jury; on July 5, the jury asked to see all of the guns
    introduced into evidence. Then came four notes in the late morning and afternoon
    of July 12, two of which prompted Judge Greene to proceed cautiously – one about
    the juror whose mind allegedly was ―made up on the first week,‖ and the other about
    the jury‘s reported deadlock on one count (out of about 27 verdicts that had to be
    rendered). Judge Greene elected to proceed cautiously, not only to avoid isolating
    the juror in question, but also to protect the secrecy of the jury deliberations and the
    right of the accused to a fair trial, as our case law dictates. See Brown, 
    supra,
     818
    31
    A.2d at 184-85; Shotikare, 
    supra,
     
    779 A.2d at 345
    . Judge Greene recognized the
    need for more information about the juror whose mind allegedly had been made up,
    but he also gleaned that the foreperson had a tendency to ―talk expansively‖ and that
    she was a ―fairly voluble foreperson.‖ Consequently, the judge decided to proceed
    ―incrementally,‖ as Counsel for Mr. Fortson described Judge Greene‘s planned
    procedure, and to pose limited questions to the foreperson.
    The question we confront is whether Judge Greene proceeded too cautiously
    and whether he at least should have made inquiry of the juror whose mind allegedly
    had been made up. Our task is not to second-guess Judge Greene on the cold record
    but to determine whether he abused his discretion, see Johnson v. United States, 
    398 A.2d 354
     (D.C. 1979), by not conducting a more extensive investigation. Judge
    Greene obviously painstakingly discussed and weighed the views and suggestions of
    defense counsel and the prosecutor, even allowing defense counsel time to caucus.
    These views and suggestions ranged from seeking clarification from the foreperson,
    speaking with the juror whose mind was made up, considering replacing that juror,
    and making inquiry of all the jurors as to whether the juror in question had spoken
    with them.
    32
    At the end of the discussion and weighing process, Judge Greene decided to
    pose limited questions to the foreperson and to instruct the foreperson not to discuss
    the matter with other jurors, and further, he chose not to interview the juror in
    question. We see no abuse of discretion regarding Judge Greene‘s approach, given
    the factual context for the judge‘s decision, especially the context that (1) the
    conversation between the foreperson and the juror in question occurred during the
    first week of a relatively long trial; (2) no other juror was present during that
    conversation; (3) the jury apparently was deadlocked only as to one count when the
    July 12 notes were sent; and (4) Judge Greene gave a thorough and balanced
    statement to the jury on July 16 (a) acknowledging the difficult task facing the
    jurors, (b) expressing the need for civility, and (c) inviting any juror who could not
    follow the court‘s instructions to send him a note in writing. His decision certainly
    avoided isolating the juror in question and protected the integrity of the jury process.
    Moreover, his invitation to jurors who could not follow his instructions reflected the
    ―usual presumption . . . that jurors understand and follow the judge‘s instructions.‖
    Hankins, supra, 3 A.3d at 363 n.23 (internal quotation marks and citation omitted).
    In short, we discern no abuse of discretion with respect to Judge Greene‘s approach
    to and resolution of the alleged juror misconduct issue.
    33
    The Urban Gun Battle and the Aiding and Abetting Instruction
    Mr. McCray, Fortson, and Parker contend that the trial court committed error
    in giving the jury urban gun battle and aiding and abetting instructions; those
    instructions pertained to count 10 of the indictment (second-degree murder and the
    lesser-included offense of voluntary manslaughter).14 Before turning to the legal
    standard and principles governing the trial court‘s jury instructions, we summarize
    14
    Mr. Parker argues that the court‘s instructions ―constituted an improper
    constructive amendment of the indictment,‖ and ―unlawfully lowered the
    government‘s burden of proof for aiding and abetting a homicide that occurs during
    an urban gun battle.‖ Mr. Fortson incorporates Mr. Parker‘s arguments. He also
    maintains that the trial court gave an ―inconsistent combination of instructions,‖
    because: (1) ―[u]rban gun battle liability may arise where the princip[a]l[] shooter
    is unknown, but aiding and abetting theory assumes existence of a principal shooter
    because, among other things, under aiding and abetting theory, knowing association
    with the principal is required‖ (citing case law); and (2) ―[a]fter telling the jury that
    Mr. Fortson did not need to have fired the fatal shot to be guilty, as long as he
    actively participated in the gun battle . . ., the trial court told the jury that under an
    aiding and abetting theory Mr. Fortson could actually be guilty of Mr. [Buckner‘s]
    death regardless of whether he did any shooting and even if he was not present – i.e.,
    not part of the gun battle at all!‖ Mr. McCray also asserts that the combination of
    urban gun battle and aiding and abetting instructions resulted in a constructive
    amendment of the indictment. He argues that, ―Aiding and abetting should not be
    given along with an urban gun battle instruction because an urban gun battle is a
    special case of aiding and abetting,‖ and because ―the aiding and abetting instruction
    mitigates the requirement that [a]ppellant‘s actions were a substantial factor in
    Antw[a]n Buckner‘s death and that it was reasonably foreseeable that death or
    serious bodily injury would result to an innocent bystander as a result of
    [a]ppellant‘s actions.‖
    34
    key parts of the instructions and discussions between the court, defense counsel, and
    prosecutor.
    Factual Context
    Before closing arguments, the trial court instructed the jury. The court began
    with general propositions and legal concepts or principles. Included in this section
    of the charge were principles relating to ―aiding and abetting.‖ Judge Greene
    informed the jurors, in part, that to convict on a theory of aiding and abetting, they
    ―must find that the defendant‖ (1) ―knowingly associated himself with the
    commission of the crime‖; (2) ―participated in the crime as something he wished to
    bring about‖; (3) ―intended, by his actions, to make the crime succeed‖; and (4)
    engaged in ―some affirmative conduct . . . in planning or carrying out [the] crime.‖
    The judge also declared, ―It is not necessary that you find a defendant charged as an
    aider and abett[o]r was actually present while the crime was committed.‖ After
    completing his instructions regarding general propositions and legal principles,
    Judge Greene began the charge as to each count of the indictment.
    35
    When he reached count 10 of the indictment, Judge Greene first read the count
    to the jury:
    Mr. Parker, Mr. Fortson, Mr. Henson and Mr.
    McCray . . . while armed with a firearm, and with the
    intent to kill another and to inflict serious bodily injury on
    another and with conscious disregard of an extreme risk of
    death or serious bodily injury to another, caused the death
    of Antw[a]n Buckner by engaging in a gun battle, on or
    about May 30, 2010, which [gun] battle caused injuries
    from which Antw[a]n Buckner died on or about June 3,
    2010.
    After setting forth the elements of second-degree murder while armed, and
    other matters, the court explained that, in this case, the government was not required
    ―to prove that a defendant personally fired the fatal round,‖ and that if the
    government proved the following elements, ―[t]hen, as a matter of law, . . . that
    defendant is deemed to have caused the death of Mr. Buckner‖:
    [F]irst that the defendant was armed with a firearm
    and prepared to engage in a gun battle[.] [S]econd, that
    the defendant did, in fact, engage in a gun battle on the
    date and at the place during the time Mr. Buckner was
    shot. Third, that the defendant did not act in self-defense
    or defenses of another . . ., at the time he participated in the
    gun battle. Fourth, that the defendant‘s conduct on the
    date and at the place during the time Mr. Buckner was shot
    was a substantial factor in the death of Mr. Buckner.
    Fifth, that at the time of the defendant‘s conduct, he
    intended to kill or seriously injure another person or acted
    36
    in conscious disregard of an extreme risk of death or
    serious bodily injury to another person. And sixth, that it
    was reasonably foreseeable the death or serious bodily
    injury to innocent bystanders could occur as a result of the
    defendant‘s conduct on the date and at the place during the
    time Mr. Buckner was shot.
    The court also stated, in part, ―any person who in some way intentionally
    participates in the commission of a crime, can be found guilty, either as an aider and
    abett[o]r or as a principal offender.‖ After reminding the jurors that he had already
    instructed them on the elements of second-degree murder, Judge Greene again
    turned to aiding and abetting, reiterating some principles, before saying:
    [W]ith regard to the charges against Mr. Parker, Mr.
    Fortson, Mr. Henson, and [Mr.] McCray under this count,
    you‘re instructed that one of the theories under which each
    of them is charged is aiding and abetting, as I have
    explained that to you, and you should consider their guilt
    or innocence of the charge under this count in accordance
    with the princip[les] of aiding and abetting.
    During a break in the instructions, Judge Greene expressed concern to the
    prosecutor and defense counsel about the urban gun battle and aiding and abetting
    instructions and asked the prosecutor, ―Is your theory that when you prosecute under
    the urban gun battle theory, that somebody can be found guilty as a principal under
    the urban gun battle theory, or an aider and abett[o]r under that theory, or is aiding
    37
    and abetting separate from and a different theory from urban gun battle?‖ The court
    also stated, ―the way the instruction is given to the jury, it imparts to the jury that the
    jury can look at this urban gun battle prosecution, and they can convict the defendant
    as either a principal on this urban gun battle theory, or an aider and abett[o]r on this
    urban gun battle theory. And we never discussed that, nobody ever raised the
    issue.‖ The prosecutor responded, ―I think that legally they could.‖ In addition,
    the prosecutor asserted ―that urban gun battle is a causation instruction.‖ After
    further ―back and forth‖ discussion, Judge Greene asked for ―a scenario, based on
    the evidence in this case, under which a defendant . . . could be convicted as an aider
    and abett[o]r, but not under the urban gun battle theory.‖ The prosecutor replied
    that if the jury ―determine[s] that Mr. McCray aided and abetted in the commission
    of this crime by sort of getting everything started, but then they look at urban gun
    battle, and they look at causation, and they say . . . [m]aybe he wasn‘t a substantial
    factor in bringing about [Mr. Buckner‘s] death, [he] could still be guilty under aiding
    and abetting liability, even though [he was] not a substantial factor in bringing about
    the death.‖ 15     Judge Greene ended the discussion by observing that ―the
    15
    Even though no 380 casings from Mr. McCray‘s gun were found around
    the circle, the prosecutor ―guess[ed]‖ that ―theoretically‖ his defense counsel could
    argue that Mr. McCray ―went down and shot at the Avenue, but he didn‘t come back
    up and shoot at the circle.‖ However, the prosecutor believed that ―[u]nder aiding
    (continued…)
    38
    [g]overnment‘s theory is that you can be a participant in an urban gun battle that is a
    second degree murder as either an aider or abettor or a principal. But I say [in the
    instructions] that all of these people are charged as aiders and abettors . . . but, in
    fact, they‘re all charged as principals under an urban gun battle theory.‖ Judge
    Greene invited the parties to give him ―a case or some authority‖ on the matter. On
    the following day, no counsel presented him with a case or other authority, and
    Judge Greene continued instructing the jury.16
    Applicable Legal Standard and Principles
    Our review of this jury instructional issue is guided by the following legal
    standard and principles. ―Where an objection to a jury instruction was preserved at
    (…continued)
    and abetting, the jury could still find Mr. McCray guilty, because he went down and
    set the whole thing off by shooting at the Avenue.‖
    16
    After closing arguments, the trial court expressed concern to counsel that
    the prosecutor‘s rebuttal emphasized only one of the six elements of the urban gun
    battle theory. Therefore, Judge Greene informed the jury that he wanted ―to focus
    on [that theory] for a moment‖ because of comments made by the lawyers during
    closing arguments. He essentially repeated his instructions, setting forth all six
    elements of the urban gun battle theory.

    An individual who intentionally participates in a gun battle among feuding
    individuals is guilty of the murder of a bystander if the gun battle was the proximate
    cause of the injuries that resulted in the victim‘s death.17 Roy v. United States, 871
    17
    The trial court instruction regarding an urban gun battle and proximate
    causation that the majority approved in Roy was as follows. ―The instruction on
    causation, under the lesser included offense of second-degree murder‖ began with
    the first element of proximate causation:
    A person causes the death of another person if his
    actions are a substantial factor in bringing about the death
    and if death is a reasonably foreseeable consequence of his
    actions.     Death is reasonably foreseeable if it is
    something which should have been foreseen as reasonably
    related to the defendant‘s actions.
    Before stating the second, third and fourth elements of proximate causation, the trial
    judge focused on the urban gun battle theory and charged the jury as follows:
    It is not necessary for the government to prove that
    (continued…)
    
    40 A.2d 498
    , 507 (D.C. 2005) (―increased risk to innocent bystanders . . . justifies the
    (…continued)
    a defendant personally fired the fatal round in this case.
    Rather if you are convinced beyond a reasonable doubt
    that:
    One, the defendant was armed and prepared to
    engage in a gun battle;
    Two, that the defendant did, in fact, engage in a gun
    battle on the 3400 block of Tenth Place, Southeast on June
    12, 2000;
    Three, that the defendant did not act in self-defense
    . . . at the time he participated in a gun battle;
    Four, that the defendant‘s conduct on Tenth Place
    on June 12th, 2000 was a substantial factor in the death of
    [the victim]; and
    Five, that it was reasonably foreseeable that death
    or serious bodily injury to innocent bystanders could
    occur as a result of the defendant‘s conduct on Tenth Place
    on June 12th, then, as a matter of law, the defendant is
    deemed to have caused the death of [the victim].
    The trial judge returned to proximate cause, indicating that, ―The government must
    prove causation beyond a reasonable doubt.‖ The judge then added the second,
    third and fourth elements of the lesser included offense of second-degree murder:
    Two, that at the time the defendant did so, he had
    the specific intent to kill or seriously injure the decedent,
    or acted in a conscious disregard of an extreme risk of
    death or serious bodily injury to the decedent;
    Three, there were no mitigating circumstances. . . ;
    Four, . . . he did not act in self-defense [.] . . .

    engage in [urban gun] battles‖).
    A constructive amendment of the indictment can occur if, and only if, the
    prosecution relies at the trial on a complex of facts distinctly different from that
    which the grand jury set forth in the indictment.‖ Id. at *98 (internal quotation
    marks and citation omitted). ―In a variance, the proof at trial does not show such a
    distinctly different complex of facts, nor does the proof differ from the essential
    elements of the offense charged in the indictment.‖          Id. at *98-99 (internal
    quotation marks and citation omitted).        ―A variance is prejudicial if it either
    deprives the defendant of an adequate opportunity to prepare a defense . . . or
    exposes him to the risk of another prosecution.‖ Id. at *99 (internal quotation
    marks and citation omitted).
    Discussion
    We first address Mr. McCray‘s, Fortson‘s, and Parker‘s argument that the trial
    court‘s instructions constituted an improper constructive amendment. From the
    outset of the case, the government‘s clear emphasis was on the urban gun battle at
    42
    Benning Terrace between the Avenue and the circle, and the proximate cause theory
    to support its second-degree murder charge relating to Mr. Buckner. In closing
    argument, one of the prosecutors told the jury ―that these guys engaged in a gun
    battle and it doesn‘t matter who fired that fatal shot‖; that ―the law [says] . . . that all
    participants can be held responsible if their actions are a substantial factor in the
    death of the person‖; and the fact that ―there‘s no evidence that any of [the] four guns
    shot the fatal bullet that hit [Mr.] Buckner‖ does not matter, as long as the men had
    the requisite intent and ―act[ed] in conscious disregard of an extreme risk of death or
    serious bodily injury.‖ During the government‘s rebuttal, the other prosecutor
    stressed the proximate cause theory of the urban gun battle, telling the jury that
    ―[e]very one of these men is a substantial factor in bringing about Mr. Buckner‘s
    death‖; and that ―the law recognizes that when you have two groups of men who turn
    that parking circle into a war zone and . . . an innocent bystander [] gets hit,
    everybody is held responsible.‖ 18         Neither prosecutor mentioned aiding and
    abetting during closing and rebuttal arguments.
    18
    Because of his concern that, in rebuttal, the prosecutor mentioned only the
    fourth element (―the ―substantial factor‖ element) of the urban gun battle theory,
    Judge Greene reiterated all six elements of the theory.
    43
    Thus, the government‘s evidence and arguments at trial reflected and were
    consistent with the charge in count 10 of the indictment – that the defendants ―while
    armed with a firearm, and with the intent to kill another and to inflict serious bodily
    injury on another and with a conscious disregard of an extreme risk of death or
    serious bodily injury to another, caused the death of Antwan Buckner by engaging in
    a gun battle, on or about May 30, 2010, which gun battle caused injuries from which
    Antwan Buckner died on or about June 3, 2010.‖ Since ―the prosecution [did not
    rely] at the trial on a complex of facts distinctly different from that which the grand
    jury set forth in the indictment,‖ Peay v. United States, 
    924 A.2d 1023
    , 1027 (D.C.
    2007) (internal quotation marks and citation omitted), there was no constructive
    amendment of the indictment.
    Second, we cannot agree that Mr. McCray‘s, Fortson‘s, and Parker‘s
    convictions as to count 10 should be reversed because the judge gave the jury
    second-degree and voluntary manslaughter instructions together with the urban gun
    battle and aiding and abetting instructions. The record reflects some confusion as
    to whether the aiding and abetting instruction should have been given in this case.
    Nevertheless, where (a) the indictment charged defendants McCray, Fortson,
    Parker, and Henson as co-principals in a murder resulting from an urban gun battle,
    44
    and (b) the prosecution did not argue, as an alternative, that defendants could be
    guilty of aiding and abetting the murder of Mr. Buckner, we conclude that even
    assuming the defendants objected to and preserved their aiding and abetting claim as
    to second-degree murder and voluntary manslaughter, and even assuming, without
    deciding, that the trial court erred by giving the aiding and abetting instruction in this
    case, the alleged error would be harmless. Kotteakos v. United States, 
    328 U.S. 750
    , 765 (1946). The record does not reflect any prejudice to the defendants
    because: (1) as previously indicated, the prosecution did not make an aiding and
    abetting argument to the jury; (2) as we hold below, the government‘s evidence was
    sufficient to convict Mr. McCray, Mr. Fortson, and Mr. Parker of voluntary
    manslaughter as co-principals beyond a reasonable doubt; and (3) the record reflects
    that the jury carefully and thoughtfully considered the charges and evidence against
    each of the defendants before rendering guilty verdicts on count 10 against Mr.
    Parker, Mr. Fortson, and Mr. McCray, and a not guilty verdict as to Mr. Henson.
    45
    Sufficiency of the Evidence
    Appellants’ Arguments
    Mr. McCray asserts that the evidence was insufficient to convict him of
    AWIKWA (Count 8) and the related PFCV count (Count 9). With respect to count
    10, he contends that ―there is no evidence of the details of [his] firing during the
    gunfight resulting in the Buckner homicide,‖ and that this conviction ―should not
    stand as a result of the [jury instructional] issue.‖19 Mr. Henson challenges his
    CPWL conviction on sufficiency grounds, and Mr. Fortson contends that the
    evidence was insufficient with respect to his lesser-included ADW conviction
    (Count 5) and the related PFCV and CPWL convictions (Counts 6 and 7).
    Applicable Standard of Review
    ―When analyzing 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 jury to

    Mr. Fortson also maintains that his count 10 conviction should be reversed
    because of the jury instructional issue.

    and making no distinction between direct and circumstantial evidence.‖ Medley v.
    United States,

    520 A.2d 255
    , 263 (D.C. 1987)) (internal quotation marks omitted). A ―motion for
    judgment of acquittal must be granted if the evidence, when viewed in the light most
    favorable to the government, is such that a reasonable juror must have a reasonable
    doubt as to the existence of any of the essential elements of the crime.‖ Curry,
    
    supra,
     
    520 A.2d at 263
     (emphasis in original) (citation omitted). ―[I]t is only where
    the government has produced no evidence from which a reasonable mind might
    fairly infer guilt beyond a reasonable doubt that the court can reverse a conviction.‖
    Medley, supra, 104 A.3d at 127 n.16 (internal quotation marks and citation omitted).
    Mr. McCray’s Arguments Pertaining to Counts 8 and 9
    Mr. McCray argues that ―[t]here is a dearth of evidence regarding [c]ounts 8
    and 9.‖ Count 8 of the indictment charged that Mr. McCray, Hebron, and Mungo
    ―while armed with a firearm, assaulted persons whose identities are unknown to the
    Grand Jury with the intent to kill‖; and count 9 charged that each of the three men
    possessed ―a firearm‖ while committing the assault. Mr. McCray claims that the
    47
    government failed to prove specific intent with respect to count 8 because no proof
    was presented as to ―the distance between the shooter and the victim.‖ He contends
    that ―[t]he jury had no idea how far away [Mr. McCray] was from the targets or in
    what direction he fired or any other facts creating an AWIK inference.‖
    Applicable Legal Principles
    To prove Mr. McCray committed the charged AWIKWA offense, the
    government had to present evidence showing beyond a reasonable doubt that he:
    ―(1) made an assault on [unknown men]; and (2) did so with specific intent to kill;
    (3) while armed.‖ Hagans v.United States, 
    96 A.3d 1
    , 42, n.131 (D.C. 2014) (citing
    Nixon v. United States, 
    730 A.2d 145
    , 148 (D.C. 1999)). ―To prove a specific intent
    to kill, the government is not required to show that the accused actually wounded the
    victim.‖ Nixon, 
    supra,
     
    730 A.2d at
    148-49 (citing Bedney v. United States, 
    471 A.2d 1022
    , 1024 (D.C. 1984)).         ―[S]pecific intent may be shown through
    circumstantial evidence,‖ id. at 149 (citation omitted), and ―may be inferred from a
    defendant‘s actions,‖ McKnight v. United States, 
    102 A.3d 284
    , 288 (D.C. 2014).
    Moreover, ―[t]he presence of a motive suggests a purposeful or reasoned killing.‖

    454 A.2d 314
    , 317 (D.C. 1982) (citations omitted).
    48
    Discussion
    The government presented compelling evidence against Mr. McCray from
    which reasonable jurors could justifiably infer that during the first shootings on May
    30, Mr. McCray made an assault on young men from the Avenue, with the specific
    intent to kill them while armed. From Mr. Clay‘s testimony, if believed, jurors
    could reasonably infer that the feud between those identifying with the circle and
    those with the Avenue was intense because it involved the use of guns by persons
    who were, as Mr. Clay put it, ―trying to kill each other.‖ Mr. Johnson heard Mr.
    McCray confirm that intent by saying, ―he kill[ed] when he was over there [the
    Avenue], some bi**h a*s nig**s.‖ During a conversation with Mr. Wages, Mr.
    McCray admitted that he was shooting at the Avenue with Mr. Mungo on May 30;
    Mr. Clay made the same statement to Mr. Faison. Moreover, this court‘s case law
    does not require the government to prove specific intent by establishing the exact
    distance between the shooter and the unknown persons who were assaulted.
    In sum, as to counts 8 and 9 charged against Mr. McCray, reasonable jurors
    could justifiably infer that Mr. McCray took part in the first shootings on May 30,
    before Mr. Buckner was killed, given (1) the relatively close proximity of apartment
    49
    buildings 610, 603 and 605 and the accessible paths between the circle and the
    Avenue, as shown by government exhibits; (2) the intensity of the feud between
    those associated with the circle and those with the Avenue; (3) Mr. McCray‘s
    statement, revealed by Mr. Johnson, about killing some ―bi**h a*s nig**s‖ when he
    was over at the Avenue, and Mr. McCray‘s admission to Mr. Wages that he (Mr.
    McCray) was shooting at the Avenue on May 30; (4) testimony about Mr. McCray‘s
    possession and firing of guns; and (5) the appearance of individuals from the
    Avenue in the circle. Consequently, we hold that the evidence was sufficient to
    convict Mr. McCray of counts 8 and 9 beyond a reasonable doubt.
    The Second Shooting on May 30 (Count 10)
    With regard to the second shooting on May 30 that was related to Mr.
    Buckner‘s murder (Count 10), neither Mr. Fortson nor Mr. Parker challenges the
    sufficiency of the evidence; rather, they focus on the alleged instructional error that
    we discussed in the prior section of this opinion.           Although Mr. McCray
    emphasizes the alleged instructional error, he also asserts that ―there is no evidence
    of the details of [his] firing during the gunfight resulting in the Buckner homicide,‖
    but the record does not support this assertion and we conclude that Mr. McCray‘s
    50
    challenge to the sufficiency of the evidence as to count 10 is unpersuasive. When
    Mr. Clay heard shots ―coming from the Avenue,‖ he saw Mr. McCray, Mr. Hebron
    and Mr. Mungo walk by the parking lot where dumpsters were located and where
    evidence technicians found cartridge casings. Mr. Clay also witnessed Mr. McCray
    standing with Mr. Mungo in the parking lot area while taking turns firing a Glock,
    one of the weapons with which the firearms expert identified the retrieved casings
    from the parking lot/dumpster area. In addition the government presented ballistics
    evidence collected from the area where Mr. McCray and Mr. Mungo were seen
    firing the Glock. In sum, we hold that the evidence was sufficient to convict Mr.
    Fortson, Mr. McCray, and Mr. Parker, as co-principals, of voluntary manslaughter
    (Count 10) and the related weapons charges pertaining to Mr. Buckner‘s murder.
    Mr. Henson’s CPWL Conviction (Count 16)
    Mr. Henson challenges his conviction of CPWL under count 16 of the
    indictment. Count 16 charged Mr. Henson with carrying a pistol without a license
    ―on or about May 31, 2010 and in June 2010.‖ 
    D.C. Code § 7-2501.01
     (12) (2012
    Repl.) defined ―pistol‖ as ―any firearm originally designed to be fired by use of a
    single hand or with a barrel less than 12 inches in length.‖ Mr. Henson emphasizes
    51
    the government‘s alleged lack of proof that he possessed a gun with a barrel less than
    12 inches in length. He also highlights Ms. Rajah‘s testimony that when she saw
    Mr. Henson shooting a gun in June 2010, she was unable to identify the type of gun
    he used. In addition, Mr. Clay, who used to reside with Mr. Henson, testified that
    he ―always‖ saw Mr. Henson with ―handguns‖ between 9 and 10 inches or 9 and 11
    inches in size, but he never saw Mr. Henson with a big rifle or shotgun; Mr. Clay‘s
    observations included the period in April and May 2010.
    This court previously has declared that ―it is not strictly necessary to prove
    barrel length in order to establish that a particular firearm is a pistol.‖ Harrison v.
    United States, 
    76 A.3d 826
    , 840 (D.C. 2013). Nevertheless, the evidence presented
    here is very thin; in short, it is not compelling. Viewed in the light most favorable
    to the government, the evidence from Mr. Clay established that Mr. Henson
    possessed handguns whose barrels were less than 12 inches in length, and Mr. Clay
    had never seen him with a big rifle or shotgun. But, that testimony was insufficient
    to establish beyond a reasonable doubt that Mr. Henson was shooting with a pistol
    ―in or about May 31, 2010[,] and in June 2010.‖ Furthermore, Ms. Rajah could not
    identify the type of firearm Mr. Henson had when she saw him shooting in June
    2010. The government argues that Ms. Rajah ―was close enough to describe a rifle
    52
    or a shotgun had she seen one, but she could not, which supports the inference that
    the weapon used was a pistol.‖ Rather than a justifiable inference, we think the
    government‘s argument is speculation and does not rise to the level of proof beyond
    a reasonable doubt. See Rivas v. United States, 
    783 A.2d 125
    , 134 (D.C. 2001) (en
    banc) (―The evidence is insufficient if, in order to convict, the jury is required to
    cross the bounds of permissible inference and enter the forbidden territory of
    conjecture and speculation.‖) (internal quotation marks, alteration, and citation
    omitted).
    Mr. Fortson’s ADW Conviction (Counts 5 and 6)
    Mr. Fortson challenges the sufficiency of the evidence with respect to his
    lesser-included ADW conviction related to counts 5 and 6 of the indictment,
    indicating that around April or May 2010, ―while armed with [a] firearm[], [he]
    assaulted persons whose identities are unknown to the Grand Jury with intent to
    kill.‖ Mr. Brown, a maintenance employee of the District‘s Housing Authority was
    on duty when he saw Mr. Thomas and Mr. Fortson. Mr. Thomas started shooting at
    young men who were walking up G Street in the Benning Terrace complex. Mr.
    Fortson had a small handgun and he went behind a building on the right side of 46th
    53
    Place. Mr. Brown took cover and heard ―a whole lot of shooting . . . back and
    forth.‖ After the shooting and during words uttered in Mr. Brown‘s presence, Mr.
    Fortson declared, ―[my] bad‖ or ―[my] bag.‖ Reasonable jurors could reasonably
    and justifiably infer that Mr. Brown heard shots coming from the gun in Mr.
    Fortson‘s hands, and that Mr. Fortson‘s words, ―[my] bad‖ or ―[my] bag‖ constituted
    an apology and a consciousness of his guilt for putting Mr. Brown in danger. In
    short, the government‘s proof was sufficient to sustain the ADW conviction and the

    Investigation of Mr. Faison’s Alleged Mental Disabilities
    Mr. Parker argues that the trial court ―deprived [him] of the opportunity to
    fully challenge [Mr.] Faison‘s credibility before the jury,‖ and he further asserts that
    ―the trial court … erred when it refused to allow defense counsel to investigate and
    54
    challenge the mental disabilities of key government witness Faison.‖ Mr. McCray
    complains that ―the failure to permit cross or get a physician‘s opinion [about Mr.
    Faison‘s mental state] was reversible error.‖ We first detail the factual context for
    this issue.
    Factual Context
    Opening statements in this case began on May 7, 2012; at that time, Mr.
    Faison was a co-defendant. On June 12, Mr. Faison entered a guilty plea and
    agreed to testify against his former co-defendants. The parties discussed his plea
    agreement and its impact on June 11 and 12, 2012. Mr. Faison testified on June 18
    and 19.       Defense counsel sought access to Mr. Faison‘s juvenile records to
    determine his medical history, and a Superior Court judge signed an order granting
    access to the records. Among the records found by counsel for Mr. Henson was a
    thirteen-page psychiatric evaluation, dated May 26, 2006, showing a diagnosis of
    bipolar disorder. Counsel for Mr. Parker asked for an expert to evaluate Mr. Faison
    and to determine the impact of mental illness on Mr. Faison‘s credibility. Counsel
    indicated that he could not say ―it will impact credibility, or . . . it will generate
    useful material for impeachment purposes or indeed for cross-examination,‖ but that
    55
    his ―client is entitled to explore that possibility.‖ The prosecutor recognized that
    the report mentioned ―severe impairment of prefrontal function,‖ but she argued that
    Mr. Faison‘s abnormalities were known because the report listed them as ―impaired
    visual tracking, abnormal muscle tone, difficulty performing simple motor
    movements that require coordination, a snout reflex, and a trace suck reflex.‖ Both
    the prosecutor and the court acknowledged that they did not know what some of the
    terms meant.
    The court and counsel reviewed applicable case law. In the course of the
    discussion, the court admonished one of the prosecutors for putting a person with
    ―serious questions regarding his credibility, in terms of his history[,] . . . on the stand
    in the last minute in the trial‖ when ―the defense has no chance to investigate him.‖
    The court described Mr. Faison‘s testimony as ―powerful,‖ said he would be
    ―astounded‖ if jurors believed it, but that ―his testimony, if believed by the jury[,] is
    compelling.‖ The prosecutor insisted that Mr. Faison‘s mental history was known
    – bipolar disorder, ADHD, and addiction to cannabis. Furthermore, the prosecutor
    argued that defense counsel had not made ―a proffer to show why they‘re entitled to
    even obtaining an expert, or going . . . beyond what they have in this [2006] report.‖
    Counsel for Mr. Henson attempted to clarify the request for an expert made by Mr.
    56
    Parker‘s counsel saying, ―only an expert would know what the terms mean about the
    prefontal [function] and the neurological problems, deficiencies that [the doctor who
    wrote the report] noted,‖ and ―what [impact] the neurological damage has on
    credibility, ability to tell the truth.‖
    Ultimately the court concluded that there was no reason to delay the trial
    based on a six-year old report and the absence of ―some seriously relevant
    information . . . that even arguably affects [Mr. Faison‘s] ability to recall or perceive
    or develop.‖      In the event that ―some seriously relevant information‖ was
    uncovered, the court indicated that defense counsel could file ―a motion for a new
    trial, based on newly discovered evidence, [or] a new trial in the interest of justice.‖
    When the trial court indicated that ―there‘s nothing here [that is, in the psychiatric
    report] that reflects on [Mr. Faison‘s] credibility,‖ Mr. Parker‘s counsel responded,
    ―these visual tracking issues . . . could be reflective of some organic defect.‖ The
    court noted counsel‘s use of the word ―could.‖ Counsel for Mr. Parker ―agree[d]
    [that] bipolar shouldn‘t go to credibility,‖ but he contended that ―it‘s not just the
    bipolar disorder,‖ that ―there could be something . . . [t]hat could be developed,‖ and
    that defense counsel had ―a good-faith basis . . . to have an expert . . . to see if there is
    57
    a basis to go forward.‖ 20 After counsel for Mr. McCray and Mr. Fortson also
    argued the need for time to examine the situation further, the court summarized its
    views, concluding that if it had ―any reason to believe that there was even a slim
    likelihood . . . that this record was going to develop in the direction of suggesting
    grounds to have a mental examination of Mr. Faison, because he had mental issues
    that affected his ability to recall, or his ability to perceive,‖ the court ―would move in
    a different direction.‖ And, ―if this record suddenly disclose[d] something,‖ the
    court would have to make a decision.21 The court observed that the jury had been in
    court ―for almost two months‖ and there was no ―meritorious basis‖ for delay.
    Applicable Legal Standard and Principles
    The applicable legal standard and principles pertaining to this issue are as
    follows.   ―[A] trial judge is entrusted with broad discretion to determine the
    substance, form, and quantum of evidence which is to be presented to a jury.‖
    Johnson v. United States, 
    452 A.2d 959
    , 960 (D.C. 1982) (citations omitted). Thus,
    20
    Counsel cited Mr. Faison‘s alleged present jail conduct stating that Mr.
    Faison ―testified that he threw feces and urine on a guard.‖
    21
    Counsel for Mr. Parker maintained that, ―No one is contesting that Mr.
    Faison lacks competency, but he lacks credibility.‖
    58
    ―[w]e review the trial court‘s rulings placing limitations on cross-examination for an
    abuse of discretion.‖ Bennett v. United States,

    court precludes a meaningful degree of cross-examination to establish bias.‖

    United States, 
    587 A.2d 456
    , 458 (D.C. 1991) (per curiam). With respect to

    and relate purported facts, as well as testify truthfully.‖

    Discussion
    Here, a 2006 psychiatric evaluation, found in Mr. Faison‘s juvenile medical
    records, revealed that he had been diagnosed with bipolar disorder.             Bipolar
    disorder may be related to credibility, and an expert‘s evaluation may show the
    connection between that disorder and credibility. See United States v. George, 
    532 F.3d 933
    , 937 (D.C. Cir. 2008) (―We do not foreclose the possibility that testimony
    by an expert, which the trial judge suggested, could have shown evidence of Ms.
    George‘s [bipolar] condition to be relevant to her credibility and sufficiently distinct
    from evidence of drug use and violence that the Confrontation Clause might require
    its admission.‖). However, it was incumbent on Mr. Parker and Mr. McCray to
    indicate ―how [they] would have used evidence of this illness to impeach [Mr.
    60
    Faison‘s] testimony or why it would have cast doubt on [his] ability or willingness to
    tell the truth.‖ United States v. Baxter, 
    761 F.3d 17
    , 24 (D.C. Cir. 2014).
    In George, 
    supra,
     the district court had ―suggested the possibility of an expert
    to explain why [a witness‘] bipolar disorder would be relevant.             
    Id. at 938
    .
    Significantly, Mr. Parker and Mr. McCray requested an expert in the trial court after
    they obtained the 2006 psychiatric report about Mr. Faison; Mr. Parker‘s counsel
    argued that he was ―entitled to explore [the] possibility‖ that Mr. Faison‘s mental
    illness would impact his credibility. Mr. Parker and Mr. McCray contend on appeal
    that they needed an expert to examine Mr. Faison‘s medical records (a) to point out
    any linkage between Mr. Faison‘s bipolar disorder and his credibility, or (b) to
    determine whether anything else in his medical records reflected conditions that
    affect credibility. In the trial court and in order to counter the trial court‘s emphasis
    on the fact that the diagnosis of bipolar disorder occurred in 2006, six years prior to
    trial, Mr. Parker‘s counsel purported to offer a good faith basis for engaging an
    expert. Counsel reported a recent episode in the D.C. Jail where Mr. Faison threw
    feces and urine at a guard. However, without the assistance of an expert, Counsel
    for Mr. Parker could not say whether that incident was a manifestation of Mr.
    Faison‘s bipolar disorder that could impact his credibility.
    61
    We recognize that this court has said that, ―[o]ne‘s psychiatric history is an
    area of great personal privacy which can only be invaded in cross-examination when
    required in the interest of justice.‖ Velasquez, supra, 
    801 A.2d at 79
     (citation
    omitted). We concluded in Velasquez that ―there was no evidence offered that the
    mental condition or symptoms that [the witness] experienced in [an earlier psychotic
    delusional episode] persisted at the time of the trial.‖ We specifically noted that the
    trial court had stated, ―There is no expert opinion offered to support the defense
    theory that a psychotic delusional episode [was] relevant‖ to the credibility of claims
    made by the witness. 
    Id. at 78
    . We further said that the trial court‘s ruling that
    ―the evidence of the witness‘ mental condition three years after the offense would be
    of minimal, if any, relevance to her credibility,‖ did not constitute an abuse of
    discretion. 
    Id. at 78, 80
    .
    The situation in this case is different from that in Velasquez, however, because
    Mr. Parker and Mr. McCray requested an expert to evaluate whether there is medical
    support for their theory that Mr. Faison‘s bipolar disorder impacted his credibility.
    Noteworthy also is the fact that although the trial court found that Mr. Faison had the
    ability ―to recall‖ and ―to perceive,‖ the court raised questions about Mr. Faison‘s
    credibility, admonishing the prosecution for presenting a witness with ―serious
    62
    questions regarding his credibility, in terms of his history[,] . . . on the stand in the
    last minute in the trial‖ when ―the defense has no chance to investigate him.‖
    We understand the trial judge‘s reluctance to take a break in the middle of a
    difficult trial to permit defendants to engage an expert to evaluate Mr. Faison‘s
    mental disabilities, and to advise the defense as to the impact of any mental
    disability on Mr. Faison‘s credibility. Nevertheless, in light of defendant‘s right to
    present a defense, and given the seriousness of the bipolar disorder and the proffer
    about Mr. Faison‘s recent episode of throwing urine and feces at a prison guard, we
    believe Mr. Parker and Mr. McCray were at least entitled to an opportunity to show
    what an expert might contribute in an effort to determine any impact of Mr. Faison‘s
    mental disabilities on his credibility. Consequently, we remand Mr. Parker‘s and
    Mr. McCray‘s cases to the trial court solely to provide these appellants with an
    opportunity to show, at a hearing and through expert opinion, whether at the time of
    his trial testimony, Mr. Faison‘s mental disabilities seriously impacted his
    credibility. If the results of the hearing show that Mr. Faison‘s mental disabilities
    seriously impacted his credibility at the time of trial, then the trial court should
    determine whether it can say with fair assurance that Mr. Faison‘s testimony did not
    sway the outcome of the verdicts against Mr. Parker and Mr. McCray. Depending
    63
    on its answer to the inquiry, the trial court should either affirm all of Mr. Parker‘s
    and Mr. McCray‘s convictions, or vacate the convictions and order a new trial.
    The Remaining Issues22
    22
    We do not discuss the Brady v. Maryland, 
    373 U.S. 83
     (1963) issue raised
    in Mr. Fortson‘s brief because during the appellate argument, counsel for both Mr.
    Fortson and Mr. Parker indicated that that issue is still pending in the Superior
    Court; they asked that this court allow the trial court to address the Brady issue in the
    first instance.
    Mr. McCray and Mr. Parker contend that the trial court abused its discretion
    by not holding a pre-trial hearing on the alleged conspiracy charge. We disagree.
    In Jones v. United States, 
    99 A.3d 679
     (D.C. 2014), we rejected an identical
    contention based on Butler v. United States, 
    481 A.2d 431
     (D.C. 1984), a decision
    which we have consistently followed. We said:
    We also note that while appellant complains of the
    trial court‘s ruling declining to hold a pre-trial hearing on
    the admissibility of co-conspirator hearsay statements,
    this court has specifically instructed that the trial court
    ―should make the admissibility determination during the
    prosecution’s evidence[,]‖ ―to avoid[] the impracticality
    of [a] mini-trial[.]‖ Butler, 
    481 A.2d at 441
     (italics
    added).
    Jones, supra, 99 A.3d at 684 n.6. Here, the trial court followed Butler, and hence,
    we discern no abuse of discretion. In addition, after the government had presented
    some but not all of its evidence, the trial judge commented that he was ―satisfied at
    this point in this trial that there is ample evidence of a conspiracy that involves all six
    of [the codefendants],‖ but that he was ―not satisfied yet that the government has . . .
    presented clear and convincing evidence that the objectives of that conspiracy were
    to murder and to assault.‖ He gave defense counsel an opportunity to comment, but
    (continued…)
    64
    Mr. McCray’s Videotaped Confession
    Mr. McCray argues that ―the totality of the circumstances require a
    suppression of [his videotaped] statement.‖       He emphasizes his youth (age
    seventeen) at the time his videotaped confession occurred and maintains that his
    ―confession . . . should have been suppressed as involuntary.‖
    Factual Context
    We first set forth the factual context, and the trial court‘s findings and
    conclusions about the videotaped confession of Mr. McCray. Deputy United States
    Marshal Linwood Battle and another marshal arrested Mr. McCray on March 16,
    2011, at 612 46th Place, S.E. After knocking for thirty seconds and receiving no
    answer, the marshals forced entry and searched for Mr. McCray. When they pulled
    the pillows off of a couch to make sure Mr. McCray was not hiding there, they found
    a handgun and secured it. MPD Officer Joseph Crespo was stationed outside of the
    apartment complex, below the second floor apartment where the marshals were
    (…continued)
    counsel for Mr. Parker declined ―because that gives the government a road map to
    cure.‖
    65
    looking for Mr. McCray. He saw a window open up, and Mr. McCray tried to get
    out of the window until he saw the officer. He was apprehended by the marshals.
    Later, Officer Dwayne Mitchell was assigned to collect evidence at the apartment.
    He retrieved the gun from the couch, and identified it as a .38 caliber or ―380 auto‖
    handgun.
    Before trial, Mr. McCray filed a motion to suppress statements. The motion
    indicated that he was arrested on March 16, 2011, at age seventeen, and that he
    initially declined to answer questions without a lawyer but later waived his rights.
    He emphasized that the detectives interviewing him yelled at him; mentioned the
    eviction of his family; talked about his little sister and younger brother; berated him
    for not being honest; stated that he would never see his child again; attempted to
    convince him that ―it is eating him alive‖ (presumably because of his guilty
    involvement in second-degree murder); there was an inordinate delay in the
    questioning; the detectives used deceptive tactics and ―psychological torture‖ on a
    juvenile; and therefore, his ―alleged confession . . . [was not] ‗the product of an
    essentially free and unconstrained choice by its maker‘‖ (citing case law). He
    ended his motion by ―request[ing] that the [c]ourt conduct an independent analysis
    66
    to determine whether [his] age played a role in the voluntariness of statements
    allegedly elicited from him by experienced law enforcement officer[s].‖
    The trial court held a hearing on April 19, 2012, on Mr. McCray‘s motion.
    Deputy United States Marshal Linwood Battle, a team leader in Mr. McCray‘s
    arrest, testified as well as Detective Lee Littlejohn, one of the detectives who
    interviewed Mr. McCray. The trial court made findings of fact and conclusions on
    April 23, 2012. After indicating that he had again reviewed the videotape (parts of
    it several times) and reviewed case law, Judge Greene summarized his observations
    about the videotape in detail and articulated the ―facts [that] emerge[d]‖23; he also
    23
    Among the facts found by Judge Greene were the following. The
    ―attitude‖ of the female detective (Detective Weeks) at the outset ―was quiet and
    polite. She did not threaten [Mr. McCray] either physically or verbally.‖ Mr.
    McCray never ―ask[ed] her to stop speaking or to stop the interview.‖ When
    Detective Weeks said, ―You want me to lock up your baby sister‖ and ―This is a
    homicide. I want to get your story,‖ Mr. McCray ―raised his voice‖ and ―Detective
    Weeks then raised her voice, but it appeared she did so to be heard by the defendant
    and not in any threatening way.‖ Detective Weeks told Mr. McCray that his actions
    would ―cause [his] family to get evicted and not have a roof over their heads,‖ and
    followed that statement with the question, ―did you put the gun up under that
    cushion‖ (referring to the gun found in Mr. McCray‘s home). He replied, ―No, I did
    not put the gun in the couch under there.‖ Detective Weeks also asserted that
    everyone in the room where the gun was found would be locked up, including Mr.
    McCray‘s ―mama, sister, brother in connection with the gun.‖ Detective Weeks‘
    questioning shifted to the shooting in the circle. After about ―20 to 25 minutes into
    the interview,‖ Detective Weeks expressed frustration that she could not get Mr.
    (continued…)
    67
    reached conclusions drawn from the facts. The judge found that Mr. McCray
    arrived in the interrogation room at about 8:00 a.m., and was left alone for about two
    hours but was able to move around. During Mr. McCray‘s time in the room, ―[t]he
    police repeatedly asked [Mr. McCray] if he wanted to use the restroom or wanted
    something to drink,‖ and while Mr. McCray‘s ―leg was shackled to a chain to the
    floor, he was able to sit and stand and to move around . . . and to knock on the door of
    the room if he needed to get someone‘s attention.‖ The questioning of Mr. McCray
    ―began about 4 and a half hours after his arrest.‖ Detective Weeks and Littlejohn
    entered the room before 10:30 a.m. and Detective Weeks posed basic questions
    about Mr. McCray‘s history (e.g., date of birth, schooling, mother‘s name and cell
    phone number). ―He was initially advised of his rights and invoked his right not to
    speak at about 10:30 [a.m.]‖ and about one hour later waived his rights. The
    questioning lasted until approximately 1:40 [p.m.] when [a third and] last detective
    (…continued)
    McCray to tell the truth and indicated she was leaving. After further discussion,
    including Detective Weeks‘ reference to cameras in the circle and another statement
    that she was leaving, Mr. McCray stated, ―Okay. I was over there,‖ . . . ―I shot at
    him‖ (stated three times). He asserted that he ―just saw people in the court and shot
    at them,‖ and he admitted that ―I was out there‖ when the decedent (Mr. Buckner)
    was killed. Detective Littlejohn also questioned Mr. McCray.
    68
    [to interview Mr. McCray] left the interview room.‖24 While ―any time in excess of
    three hours is presumptively prejudicial,‖ said Judge Greene, ―[i]t does not appear . .
    . that there is any evidence that the police intentionally delayed their interview of the
    defendant.‖ Judge Greene determined that most of the questioning was done by
    Detective Weeks when she was alone with Mr. McCray and she ―was not in any way
    physically imposing or intimidating to the defendant,‖ and ―[a]t no time was [Mr.
    McCray] . . . threatened either verbally or physically.‖
    After reviewing the giving and waiver of Miranda rights, Judge Greene
    concluded that Mr. McCray ―fully understood his rights and that he knowingly
    waived them‖ after initially invoking his rights. With respect to the question of
    ―trickery,‖ Judge Greene stated that the detectives‘ statements to Mr. McCray ―were
    not always entirely truthful and may have stretched the truth,‖ but ―much of what
    they told him that could be viewed as most compelling in his decision to talk was
    that he already had been indicted by the grand jury. And, in fact, he had been
    indicted the day before his arrest.‖      Moreover, Judge Greene found that Mr.
    McCray ―[n]ever appeared intimidated or affected in any way by Detective Weeks
    24
    After the last detective left the room at 1:40 p.m., Mr. McCray was left
    alone from then until about 4:40 or 4:45 p.m. when the videotape ended.
    69
    raising her voice in response to similar conduct by the defendant.‖ The judge was
    troubled by the references to Mr. McCray‘s family, their eviction, and their being
    locked up because of the gun recovered at the time Mr. McCray was arrested.
    However, the judge found that these statements didn‘t have any coercive effect on
    Mr. McCray because the incriminating statements were not made immediately but
    only after Mr. McCray asked Detective Weeks to stay.
    In response to Mr. McCray‘s repeated references to his age and juvenile
    status, Judge Greene found that Mr. McCray ―is somebody who had some
    experience with the criminal justice system before this incident,‖ and the judge
    declared, ―Observing him in that interview . . . I don‘t see how anyone could
    conclude that his will was ever overborne. He was thinking a whole lot about what
    was going on and what he would do about it. He was very calculated in how he
    responded.‖ Furthermore, ―[w]hile [Mr. McCray] was 17, he was certainly a
    mature 17 for purposes of the criminal justice system‖; ―he did not have any obvious
    disabilities‖; ―[t]here were no police promises of leniency in exchange for the
    statement,‖ and no ―badgering of the defendant.‖ As a result of these findings,
    Judge Greene denied the motion to suppress statements, concluding, finally, that
    70
    ―there are no separate indicia here . . . that would prompt the [c]ourt [to] exclude
    those statements on voluntariness grounds.‖
    Detective Kenniss Weeks, the lead detective who conducted virtually all of
    the questioning of Mr. McCray, testified at trial and described the timelines of the
    day on which Mr. McCray was arrested and brought in for questioning. She stated
    that Mr. McCray had been in the interview room approximately two hours before the
    interview with him began.      After routine booking and personal information
    questions were posed, Mr. McCray invoked his rights around 10:29 a.m., and
    Detective Weeks left the interview room. Around 11:24 a.m., Detective Littlejohn
    informed Detective Weeks that Mr. McCray wanted to talk. Mr. McCray waived
    his rights. After Mr. McCray waived his rights, Detective Weeks asked him about
    the gun that was retrieved from a couch in the apartment where Mr. McCray had
    slept the night before his arrest. Mr. McCray denied that the gun was his. Mr.
    McCray admitted that he was involved in the first shooting on May 30, 2010, but he
    did not admit any involvement in the second shooting on May 30 that resulted in Mr.
    Buckner‘s death. On cross-examination, Detective Weeks acknowledged that she
    had falsely informed Mr. McCray that she had surveillance camera footage that
    depicted Mr. McCray in the circle at the time of the May 30 shooting. During
    71
    Detective Weeks‘ testimony, the trial court took judicial notice, and informed the
    jury, ―that at the time the detective was interviewing Mr. McCray, he did not have a
    lawyer and no lawyer had yet been assigned to him for this case.‖
    At the insistence of Mr. McCray‘s attorney, the trial court instructed the jury
    regarding the videotaped confession immediately after the conclusion of Detective
    Weeks‘ testimony. The judge properly instructed the jury that they could consider
    all of the conversations between the police and Mr. McCray, whether the police
    warned him of his rights, where and when the statement was made, how long it took,
    who was present, whether the police recorded some or all of the conversations with
    Mr. McCray, and ―the age, education and experience, intelligence and the physical
    and mental condition of [Mr. McCray].‖

    ―Whether [Mr. McCray‘s] statements were voluntary is a question of law
    subject to de novo review on appeal, with the appropriate deference to the trial
    court‘s factual determinations.‖ Little v. United States, 
    125 A.3d 1119
    , 1126-27
    (D.C. 2015) (internal quotation marks and citation omitted). The government must
    72
    ―prove by a preponderance of the evidence that a defendant‘s statements were given
    voluntarily.‖ 
    Id.
     (citation omitted). ―The test for determining voluntariness of
    specific statements is whether, under the totality of the circumstances, the will of the
    [suspect] was overborne in such a way as to render his confession the product of
    coercion.‖ 
    Id.
     (internal quotation marks and citations omitted). ―In deciding
    whether a suspect‘s will was overborne, the court evaluates the nature of the
    interrogation – including its duration and intensity, the use of physical punishment,
    threats[,] or trickery, and whether the suspect was advised of his rights – as well as
    the characteristics of the accused – including his age, education, prior experience
    with the law, and physical and mental condition.‖ 
    Id.
     (internal quotation marks and
    citation omitted). ―[A]n involuntary statement is inadmissible at trial for any
    purpose.‖ 
    Id.
     (citation omitted).
    Discussion
    Here, based on our review of the record, including Mr. McCray‘s motion to
    suppress the statement, the trial testimony of Detective Weeks, and the trial court‘s
    factual findings after the pre-trial hearing regarding the videotaped confession, we
    conclude that Mr. McCray‘s videotaped statement was voluntary. Judge Greene
    73
    carefully reviewed the videotape in detail; examined the totality of the
    circumstances, including the giving of Miranda warnings; considered assertions by
    Detective Weeks concerning eviction of Mr. McCray‘s family and the mention of
    Mr. McCray‘s sister and brother; and assessed factors for determining
    involuntariness. The court‘s findings clearly refute Mr. McCray‘s argument that
    the videotaped interview began at 2:30 p.m., continued until 8:23 p.m., and ―[a]t that
    point, [Mr. McCray] ha[d] been in solitary confinement for over 14 hours.‖
    Moreover, Judge Greene‘s findings – that Mr. McCray, although seventeen years
    old at the time, was ―a mature 17 for purposes of the criminal justice system,‖ and
    that his responses were ―very calculated‖ – rebut Mr. McCray‘s attempt to
    characterize his age as a ―special circumstance.‖ Furthermore, immediately after
    Detective Weeks‘ testimony, and again during final instructions, Judge Greene
    charged the jury about the factors they should use in weighing the videotaped
    evidence.
    It is clear that Judge Greene was troubled by Detective Weeks‘ verbal threats
    that Mr. McCray‘s family could be evicted and not have a roof over their heads.
    This verbal threat was a tactic designed to persuade Mr. McCray to admit that the
    gun found in the couch on which he slept the night before his arrest belonged to him.
    74
    However, when Detective Weeks posed the question, ―[D]id you put the gun up
    under that cushion,‖ Mr. McCray replied, ―No, I did not put the gun in the couch
    under there.‖ Significantly, even after Detective Weeks told Mr. McCray that his
    ―mama, sister, [and] brother‖ would be locked up because they were in the room
    where the gun was found, Mr. McCray continued to deny, and never admitted, that
    the gun was his. Hence, Detective Weeks‘ tactic failed to elicit a confession that
    the gun belonged to Mr. McCray. Mr. McCray later admitted that he participated in
    one of the shootings, but the threat of harm to his family had nothing to do with that
    admission – the family was threated only by their presence in the room where the
    gun was found, and Mr. McCray could alleviate the threat only by admitting that the
    gun was his, not by admitting to the shooting.25
    In light of the above discussion, we hold that the government proved by a
    preponderance of the evidence that the statements in Mr. McCray‘s videotaped
    confession were voluntary. Little, supra, 
    125 A.3d at 1126
    ; Dorsey v. United
    States, 
    60 A.3d 1171
    , 1205 (D.C. 2013) (en banc) (citing In re S.G., 
    581 A.2d 771
    ,
    25
    Mr. McCray does not argue on appeal that Detective Weeks used a
    coercive tactic by threatening his family in order to persuade him to confess that the
    gun belonged to him.
    75
    775 (D.C. 1990)) (―[A]s a reviewing court, we may not usurp the prerogative of the
    [trial] judge, as the trier of fact, to determine credibility and weigh the evidence.‖).
    Mr. McCray’s Severance Motion
    Mr. McCray complains that the trial court abused its discretion by failing to
    grant his motion for a severance so that he could be tried with Mr. Hebron and Mr.
    Mungo, the only other defendants charged with AWIKWA in Counts 8 and 9 of the
    indictment.26 He claims that the evidence of conspiracy was ―very weak and should
    never have gone to the jury,‖ and that the evidence against the other defendants with
    whom he was tried ―was much stronger‖ than that against him.
    26
    Here, nine defendants were charged in the indictment. The government
    wanted to try all nine defendants together, but because the courtroom could not
    accommodate a trial of nine defendants at the same time, in December 2011 the
    government informed the court of its decision to separate three of the defendants for
    a separate trial. Subsequently, Mr. McCray and others filed motions to sever; the
    trial court denied Mr. McCray‘s motion in March 2012, without prejudice.
    76
    Applicable Legal Principles
    Joinder is proper where defendants are charged with conspiracy. Ray v.
    United States, 
    472 A.2d 854
    , 858 n.7 (D.C. 1984); Davis v. United States, 
    367 A.2d 1254
    , 1260, n.10 (D.C. 1976). ―Given the vital role played by joint trials of
    defendants indicted together and properly joined, the trial court‘s denial of a
    severance may be disturbed only upon a clear showing that it has abused its
    considerable discretion.‖ Jenkins v. United States, 
    113 A.3d 535
    , 541 (D.C. 2015)
    (internal quotation marks and citations omitted). A defendant ―bears the burden of
    demonstrating   that,   as   to   him,   joinder   was   ‗manifestly   prejudicial.‘‖
    Castillo-Campos v. United States, 
    987 A.2d 476
    , 492 (D.C. 2010) (citation omitted).
    A defendant does not suffer manifest prejudice ―merely because a significant portion
    of the government‘s evidence admitted at trial is applicable only to his
    codefendants.‖ Tann, supra, 
    2015 D.C. App. LEXIS 533
    , at *126 (citing Johnson
    v. United States, 
    596 A.2d 980
    , 987 (D.C. 1991) (internal quotation marks omitted).
    77
    Discussion
    Contrary to Mr. McCray‘s argument, the charges against him did not appear
    less serious than those against others with whom he was tried. Like three of those
    with whom he was tried, Mr. McCray was charged in Counts 10, 11, and 12, relating
    to the alleged second-degree murder of Mr. Buckner. Moreover, Mr. McCray‘s
    argument about the alleged weakness of the government‘s conspiracy case is
    unavailing. Joinder is proper when defendants are charged with conspiracy, Ray,
    
    supra,
     
    472 A.2d at
    858 n.7; the joinder decision does not take into consideration the
    strength of the government‘s evidence that has not yet been presented. In addition,
    on this record, Mr. McCray has not sustained his burden of showing that as a result
    of joinder he suffered ―manifest prejudice.‖ The charges against Mr. McCray were
    not less serious than those against the other men with whom he was tried. Similar
    to those with whom he was tried, he was acquitted on the conspiracy to murder
    charge, and the jury did not reach a decision on the conspiracy to assault charge.
    Moreover, there was compelling evidence against Mr. McCray.            In short, we
    78
    discern no abuse of discretion with respect to the trial court‘s denial of Mr.
    McCray‘s motion to sever.27
    27
    Mr. Parker presents two other arguments which we treat summarily. He
    contends that his convictions should be reversed ―because of the admission of the
    highly prejudicial testimony from Ms. [] Rajah . . . that she moved from her
    apartment in the Benning[] Terrace area after the shooting in this case because she
    was afraid of Mr. Parker and two other persons.‖ We are not persuaded by this
    argument. The record shows that in cross-examining Ms. Rajah, counsel for Mr.
    Parker tried to show her bias by bringing out the fact that the United States
    Attorney‘s Office had helped her to relocate and that she had not paid any rent
    during the last year. Counsel also established during cross-examination that Ms.
    Rajah was afraid of ―Wheetie‖ because she had seen him ―shoot people,‖ and that
    she also was afraid of Mr. Magruder. On redirect examination Ms. Rajah stated
    that she left Benning Terrace because she was ―scared‖ of ―[t]hem coming after me.‖
    During voir dire out of the presence of the jury Ms. Rajah explained that she was
    also afraid of Mr. Parker because he put a gun in her home. The trial court ruled
    that defense counsel had opened the door, and Ms. Rajah testified before the jury
    that she left Benning Terrace because she was scared of Wheetie, Mr. Magruder and
    Parker. Neither Mr. Parker‘s counsel nor the prosecutor mentioned Ms. Rajah‘s
    fear during closing arguments. Under our standard of review and the circumstances
    which not only prompted Ms. Rajah to relocate but also to mention Mr. Parker‘s
    name, we conclude that the trial court did not abuse its discretion in permitting Ms.
    Rajah to specify that Mr. Parker was one of three men of whom she was afraid. See
    Hairston v. United States, 
    497 A.2d 1097
    , 1103 (D.C. 1985) (―The scope of redirect
    examination rests within the sound discretion of the trial court and will not be
    reversed absent a showing of clear abuse.‖).
    We reject Mr. Parker‘s argument that his UPF, PFCV, and CPWL convictions
    merge because these offenses were committed ―at the same time on May 30, 2010.‖
    See Blockburger v. United States, 
    284 U.S. 299
     (1932) (one offense does not merge
    with the other if one has an element that the other does not); see also Hanna v.
    United States, 
    666 A.2d 845
    , 857 (D.C. 1995); and Ray v. United States, 
    620 A.2d 860
    , 863-65 (D.C. 1993).
    79
    CONCLUSION
    In sum, we (1) discern no abuse of discretion with respect to Judge Greene‘s
    approach to and resolution of the alleged juror misconduct issue; (2) conclude that
    (a) the trial court‘s urban gun battle and aiding and abetting instructions did not
    result in a constructive amendment of the indictment, and (b) there was no prejudice
    to the defendants resulting from these instructions, and hence, any error would be
    harmless; (3) hold that the evidence was sufficient to convict Mr. McCray of counts
    8 and 9; (4) hold that the evidence was sufficient to convict Mr. Fortson, Mr.
    McCray, and Mr. Parker, as co-principals, of the lesser-included offense of
    voluntary manslaughter (count 10), as well as the related weapons charges; (5)
    reverse Mr. Henson‘s CPWL conviction on insufficiency of evidence grounds; (6)
    conclude that the government‘s evidence was sufficient to convict Mr. Fortson of the
    lesser-included offense of ADW; (7) hold that the government proved by a
    preponderance of the evidence that the statements in Mr. McCray‘s videotaped
    confession were voluntary; (8) conclude that the trial court did not abuse its
    discretion in denying Mr. McCray‘s severance motion; (9) reject Mr. Parker‘s
    contention that the trial court abused its discretion in permitting Ms. Rajah to testify
    on redirect that she relocated, in part, because of her fear of Mr. Parker, and we also
    80
    reject Mr. Parker‘s merger arguments; (10) remand Mr. Parker‘s and Mr. McCray‘s
    cases to the trial court solely to provide them with an opportunity to show, at a
    hearing and through expert opinion, whether at the time of his trial testimony Mr.
    Faison‘s mental disabilities seriously impacted his credibility; and (11) conclude
    that appellants‘ other contentions are not persuasive.
    Accordingly, we affirm Mr. Fortson‘s lesser-included ADW conviction
    (counts 5 and 6) and his lesser-included voluntary manslaughter conviction (count
    10), as well as the related weapons charges, and we reverse Mr. Henson‘s CPWL
    conviction (count 16). In addition, we remand Mr. Parker‘s and Mr. McCray‘s
    cases to the trial court solely to provide these appellants with an opportunity to show
    at a hearing and through expert opinion whether at the time of his trial testimony,
    Mr. Faison‘s mental disabilities seriously impacted his credibility.         After the
    hearing, the trial court should enter an order consistent with this opinion‘s discussion
    of the mental disabilities issue.
    So ordered.
