    KAFKER, J.    A jury convicted the defendant, Phillip Ayala,
    of murder in the first degree on the theory of deliberate
    2
    premeditation for the killing of Clive Ramkissoon.1    The
    defendant raises three core issues on appeal.    First, he argues
    that the evidence at trial was insufficient to support his
    convictions.    Second, he argues that his due process rights
    under the United States Constitution and the Massachusetts
    Declaration of Rights were violated by (i) the Commonwealth's
    failure to obtain and turn over discovery related to the sole
    defense witness's status as a confidential Federal informant,
    and (ii) the trial judge's decisions declining to compel several
    law enforcement officers to testify to the defense witness's
    status as a confidential Federal informant.     Third, he argues
    that his trial counsel was ineffective for (i) failing to retain
    and call an expert witness on the accuracy of eyewitness
    identifications, (ii) failing to retain and call an expert
    witness on ballistics evidence to testify about muzzle flashes,
    and (iii) failing to admit further evidence of the mental health
    issues and drug use of a percipient witness for the
    Commonwealth.
    For the reasons stated below, we conclude that there has
    been no reversible error.    After a thorough review of the
    record, we also find no reason to exercise our authority under
    1 The jury also convicted the defendant of the related
    charges of unlawful possession of a firearm without a license
    and unlawful possession of ammunition without a firearm
    identification card.
    3
    G. L. c. 278, § 33E, to grant a new trial or to reduce or set
    aside the verdict of murder in the first degree.    We therefore
    affirm the defendant's convictions and the denial of the
    defendant's motion for a new trial.
    Background.   We summarize the facts that the jury could
    have found, reserving certain details for discussion of the
    legal issues.
    In the early morning of June 10, 2007, Robert Perez and his
    friend, Clive Ramkissoon, attended a house party held on the
    second floor of a house in Springfield.   Upon arriving just
    before 2 A.M., Perez and Ramkissoon encountered a bouncer on the
    first floor at the bottom of the stairwell that led to the
    second floor.   The first-floor bouncer was posted there to
    search guests before letting them upstairs to the party.    After
    being searched, the two men went upstairs to the party.    As
    there were not yet many people at the party, Perez returned to
    the first floor and began speaking with the first-floor bouncer
    in the entryway of the stairwell.
    Shortly thereafter, as Perez was speaking with the first-
    floor bouncer, the defendant arrived at the party.    As she had
    done with Perez and Ramkissoon, the bouncer attempted to pat
    frisk the defendant before allowing him to enter.    The defendant
    refused.   After a brief argument related to the search, the
    defendant aggressively pushed past the bouncer and climbed the
    4
    stairs to the second floor.    A second bouncer intercepted the
    defendant on the stairs and prevented him from entering the
    party without having first been pat frisked.     The defendant
    argued with the bouncer and, after yelling and screaming at him,
    was escorted out of the house.     As the defendant was descending
    the staircase to leave, and just steps away from Perez, the
    defendant threatened to "come back" and "light th[e] place up."2
    After leaving the house briefly, the defendant returned and
    kicked in the first-floor door.3
    Throughout this interaction inside the house, Perez had an
    opportunity to observe the defendant closely for several
    minutes.4    Concerned by the defendant's threats and behavior,
    Perez returned upstairs to find Ramkissoon.     The two men walked
    onto the second-floor porch to "assess the situation" and saw
    the defendant pacing back and forth on the street in front of
    the house.    Rather than leave with the defendant still outside,
    given his recent threat to "light th[e] place up," Perez and
    2 At trial, a witness who had attended the party testified
    that the defendant was upset because he felt that hosting a
    party at the house was disrespectful to his niece, who had
    recently been killed at a nearby location.
    3 The door was kicked in with such force that police were
    later able to take a footprint impression from the door and
    confirm that it matched the defendant's shoe.
    4 Robert Perez's account of the defendant's actions was
    substantially corroborated at trial by the testimony of the
    first-floor bouncer.
    5
    Ramkissoon decided to wait on the porch for a few minutes.
    After the defendant moved out of sight, Perez, Ramkissoon, and a
    female friend decided to leave the party.
    After leaving the house, Ramkissoon and the woman began
    walking across the road, while Perez, who had stopped to tie his
    shoe, trailed slightly behind.    As they were crossing the road,
    the woman stopped in the middle of the road directly in front of
    the house and began dancing.     Perez walked over to where the
    woman was dancing while Ramkissoon kept moving down the road, to
    the left of the house, toward the area where his vehicle was
    parked.   As Perez approached the woman to guide her out of the
    way of oncoming traffic, he heard a gunshot and saw a muzzle
    flash appear near a street light located on the sidewalk in
    front of a property adjacent to the house.5    Perez saw the
    defendant holding a firearm and testified that he was able to
    identify the shooter as the defendant because the muzzle flash
    from the gun illuminated the shooter's face.    He then turned and
    ran away from the shooting as several more gunshots rang out.
    Perez, who had previously served in the United States Army,
    testified that he heard between five and seven shots, which he
    5 Perez testified that he saw the muzzle flash came from
    "the sidewalk area under the light," but later noted that he
    could not be certain whether the street light was on at the time
    of the shooting.
    6
    recognized as .22 caliber bullets based on his military
    experience.
    Perez soon circled back to where Ramkissoon's vehicle was
    parked and discovered Ramkissoon face down on the street.    Perez
    performed rescue breathing on Ramkissoon and telephoned the
    police.   Police officers arrived at the scene by approximately
    3 A.M. It was later determined that Ramkissoon died from
    multiple gunshot wounds.6   Perez was soon brought to the
    Springfield police station, where he gave a statement recounting
    the events of that morning.   At the station, Perez identified
    the defendant from a set of photographs shown to him by police,
    stating that he recognized the defendant's photograph as the
    "same person who [he] had seen in the stairwell not wanting to
    be pat frisked by the bouncer there, and then firing the gun
    outside in the street at [the victim]."
    The reliability of Perez's identification was vigorously
    challenged by defense counsel on cross-examination.   The defense
    confronted Perez on his ability to accurately identify the
    6 The police recovered five spent shell casings from the
    scene of the shooting. The medical examiner also recovered two
    spent projectiles from Ramkissoon's body. At trial, a police
    officer with special knowledge of ballistics testified that he
    performed a microscopic examination of the shell casings and the
    spent projectiles. Based on the examination, he concluded that
    all five casings came from a .22 caliber gun. He further
    concluded that both projectiles extracted from Ramkissoon's body
    came from the same weapon. The police never located the gun
    that was used to kill Ramkissoon.
    7
    shooter under the lighting conditions at the time of the
    shooting, his recollection of certain events that morning, and
    the discrepancies between Perez's statement to police on the
    morning of the shooting and his trial testimony regarding the
    defendant's height and clothing.   Additionally, the defense
    presented evidence showing that Perez suffered from bipolar
    disorder and posttraumatic stress disorder (PTSD), the latter
    being a result of his military service.7   Specifically, evidence
    showed that he sought psychiatric counselling and used marijuana
    to cope with the effects of his diagnoses.8   There was no
    evidence, however, that Perez was either suffering the effects
    of these diagnoses or under the influence of marijuana at the
    time of the shooting.
    Following the close of the Commonwealth's case-in-chief,
    the defense called a sole witness, N.F.,9 who was the disc jockey
    at the party.   N.F. testified that she knew the defendant and
    looked up to him, and had seen him multiple times that morning.
    7 The trial judge ordered Perez to undergo a competency
    examination by an independent doctor to determine whether these
    diagnoses would have an impact on his ability to testify.
    Following the examination, Perez was declared competent to
    testify.
    8 We discuss the importance of Perez's mental health
    struggles and drug use to this case in more detail, infra.
    9 Because the records concerning the witness's identity are
    subject to an order of impoundment, we use the pseudonym "N.F."
    to refer to her.
    8
    N.F. also testified that at one point, she was on the second-
    floor porch and saw the defendant emotional and upset outside
    after he had been kicked out of the house.      She and others
    attempted to comfort the defendant and suggested that he go
    home.   She testified to then witnessing the defendant leave the
    party and drive away.     N.F. was adamant that the defendant left
    approximately thirty to forty-five minutes before the shooting,
    stating that he was "gone a long time before [the shooting] even
    went down."   In response to further questioning on her certainty
    that the defendant was not at the scene at the time of the
    shooting, she testified, "He was not there.      Put my kids on it."
    Although she did not witness the shooting, she testified that
    she observed a red Taurus motor vehicle "skidding off" from the
    scene immediately after the shooting.
    The jury eventually returned guilty verdicts on all three
    charges, and the defendant was subsequently sentenced to life in
    prison without the possibility of parole.      The defendant now
    appeals.
    Discussion.      1.   Sufficiency of the evidence.   On appeal,
    the defendant argues that the Commonwealth failed to present
    sufficient evidence proving that he was the shooter.       In
    reviewing the sufficiency of the evidence, we apply the familiar
    Latimore standard.    See Commonwealth v. Latimore, 
    378 Mass. 671
    ,
    677-678 (1979).   We consider whether, after viewing the evidence
    9
    in the light most favorable to the Commonwealth, any rational
    trier of fact could have found the essential elements of the
    crimes beyond a reasonable doubt.     
    Id. The evidence
    may be
    direct or circumstantial, and we draw all reasonable inferences
    in favor of the Commonwealth.     Commonwealth v. Rakes, 
    478 Mass. 22
    , 32 (2017).    A conviction cannot stand, however, if it is
    based entirely on conjecture or speculation.     
    Id. At trial,
    the Commonwealth primarily relied on the
    eyewitness testimony of Perez to prove that the defendant was
    the shooter.     The defendant argues, however, that this testimony
    cannot be used to support his convictions because the jury were
    incapable of assessing its reliability.     The defendant's
    challenge centers on Perez's testimony that he was able to
    identify the defendant as the shooter because the muzzle flash
    from the gun "illuminated" the defendant's face.       The defendant
    argues that because the illuminating capability of a muzzle
    flash is not within the ordinary, common experience of a
    reasonable juror, the jury could not have found that the
    evidence proved beyond a reasonable doubt, without speculation,
    that the defendant was the shooter.
    Even assuming, as the defendant argues, that ordinary
    jurors are unfamiliar with the illuminating capability of muzzle
    flashes, there was independent evidence that would permit a
    rational juror to reasonably infer that the crime scene was
    10
    sufficiently illuminated at the time of the shooting to provide
    Perez with the opportunity to identify the defendant as the
    shooter.
    Evidence at trial established that the shooting took place
    near a street light located on the sidewalk in front of the
    property adjacent to the house.10   A police officer testified
    that the street lights near the location of the shooting and the
    exterior lights on a nearby building were illuminated when he
    arrived at the crime scene at approximately 4:30 A.M.11    Although
    there was no evidence whether the specific street light near
    where the shooter was standing was on at the time of the
    shooting, a juror could reasonably have inferred that if the
    street lights in the area were on at 4:30 A.M., they would have
    also been on at the time of the shooting earlier in the
    morning.12   Even if an ordinary, rational juror is unfamiliar
    10The police recovered five spent shell casings from the
    scene of the shooting. Each casing was located near the street
    light in front of the property adjacent to the house that Perez
    identified as the light under which the shooter was standing.
    The shell casings were located to the right of the street light.
    A police officer testified that, generally, shell casings
    discharged from a handgun eject to the right of the gun,
    indicating that the shooter was standing even closer to the
    street light than where the shell casings landed.
    11The officer further testified that on arriving at the
    scene, he observed that "[t]he street was illuminated."
    12This inference is further supported by the fact that
    Perez recognized the defendant while he was outside on the
    11
    with muzzle flashes, they are undoubtedly familiar with the
    illuminating capability of street lights.    This common knowledge
    would have allowed a rational juror to conclude that Perez had
    an adequate opportunity to identify the defendant as the
    shooter.    Cf. Commonwealth v. Stewart, 
    450 Mass. 25
    , 28, 33
    (2007) (evidence sufficient to prove defendant was shooter
    based, in part, on eyewitness seeing defendant shoot while
    standing in front of street light).
    In addition to the presence of the street light, the jury
    received other evidence that would have allowed them to assess
    the reliability of Perez's identification.   For example, the
    jury heard testimony that Perez had observed the defendant for
    several minutes earlier in the morning while he was in the
    stairwell.   They also heard testimony that Perez recognized the
    defendant walking on the street from the second-floor porch
    after the defendant was kicked out of the party.    Additionally,
    evidence showed that Perez successfully identified the defendant
    from a photographic array at the police station after the
    shooting.    This evidence would further have provided a rational
    juror with an adequate basis to assess the reliability of
    Perez's identification of the defendant at the time of the
    shooting.    Cf. Commonwealth v. Richardson, 
    469 Mass. 248
    , 249-
    street and Perez was on the second-floor porch earlier in the
    morning.
    12
    251 & n.3, 255 (2014) (evidence sufficient where eyewitness
    identified defendant fleeing from police from over 200 feet
    away, selected defendant's photograph from photographic array at
    police station, and had seen defendant on two prior occasions).
    The Commonwealth also presented circumstantial evidence
    linking the defendant to the shooting.    For example, prior to
    the shooting, the defendant arrived at the party and refused to
    be searched.   He was visibly upset that there was a party taking
    place at the house, and after being kicked out, he threatened to
    come back to the party and "light th[e] place up."     Soon after,
    he returned and kicked in the first-floor door with such force
    that he left a footprint on the door.    Additionally, the
    defendant was seen pacing around on the street in front of the
    house just a few minutes before Perez and Ramkissoon left the
    party and the shooting took place.   From this evidence, the jury
    could have reasonably inferred that the defendant did not want
    to be searched on the morning of June 10 because he was carrying
    a gun, that he was still near the house when the shooting
    occurred, and that his anger about the party motivated him to
    shoot Ramkissoon as he crossed the street.    This evidence, when
    taken together, "formed a mosaic of evidence such that the jury
    could conclude, beyond a reasonable doubt, that the defendant
    was the shooter" (quotation and citation omitted).    Commonwealth
    v. Jones, 
    477 Mass. 307
    , 317 (2017).     Cf. 
    id. at 316-318
                                                                      13
    (sufficient evidence that defendant was shooter where evidence
    linking him to shooting was that he generally matched
    description of person seen fleeing crime scene, he was at park
    where crime occurred that day, he grew up in area and regularly
    visited park, and he lied to police about his whereabouts that
    day).
    We therefore conclude that the evidence, when viewed in the
    light most favorable to the Commonwealth and taken together with
    the reasonable inferences drawn therefrom, was sufficient to
    support the jury's verdict that defendant was the one who shot
    and killed the victim.   See 
    Latimore, 378 Mass. at 677-678
    .
    2.   Dual sovereignty.   The defendant also argues that his
    due process rights under the Fifth and Sixth Amendments to the
    United States Constitution and art. 12 of the Massachusetts
    Declaration of Rights were violated by (i) the Commonwealth's
    failure to obtain and turn over discovery related to the sole
    defense witness's status as a confidential informant, and (ii)
    the judge's decisions declining to compel various State and
    Federal law enforcement officers to testify to the defense
    witness's status as a confidential informant.   Because we
    conclude that the informant records and sought-after testimony
    were not in the possession or control of the Commonwealth and
    that the Commonwealth did not have the burden to secure the
    Federal government's cooperation with regard to the disclosure
    14
    of this information, the judge did not abuse his discretion in
    denying and quashing the defendant's various motions and
    subpoenas.
    a.   Relevant facts.   Shortly before the trial was
    originally scheduled to begin in July 2008, the Commonwealth
    informed defense counsel that it had recently learned that a
    witness likely to be called by the defense, N.F., was a
    confidential informant for a Federal gang task force operating
    in Springfield.13   As a result of this new information, the trial
    was continued several times until over one year later in August
    2009.
    The Commonwealth's disclosure resulted in multiple motions
    by the defendant to obtain Federal records detailing N.F.'s
    status as a confidential informant (informant records) and to
    compel the testimony of Federal agents regarding the same
    through State court proceedings.14   The defendant argued that the
    13The task force included several State police officers who
    were deputized as "Special Federal Officers" for the purposes of
    participating in the task force.
    14The defendant filed a motion for the production of
    exculpatory evidence related to N.F.'s status as an informant.
    The Commonwealth opposed the motion, arguing that it did not
    have possession or control of the requested information. The
    motion judge agreed with the Commonwealth and denied the
    defendant's motion to the extent that it requested that the
    Commonwealth produce records that were not in the Commonwealth's
    possession or control. The motion judge further suggested that
    the defendant attempt to subpoena the Federal authorities for
    that purpose.
    15
    information was material to his defense because it was necessary
    to demonstrate N.F.'s credibility as a witness, which the
    defendant contended was exculpatory information.     At various
    times, the defendant was informed that a successful pursuit of
    this information would require that he comply with the procedure
    set forth by Federal regulations.    The federally mandated
    procedure required the defendant to submit a written request for
    information describing the informant records and the subject
    matter of the testimony sought.     Federal authorities would then
    review the sought-after information for privilege,
    confidentiality, and the likelihood that its disclosure would
    compromise ongoing investigations.    After this review, the
    Federal authorities would report back to the defendant and
    either disclose the requested information or explain why it was
    continuing to be withheld.   Despite being made aware of the
    Federal procedure, the defendant refused to comply and continued
    The defendant next filed a motion to examine N.F.'s records
    pursuant to Mass. R. Crim. P. 17 (a) (2), 
    378 Mass. 885
    (1979).
    The motion judge allowed the defendant's motion under rule 17,
    and summonses to various Federal agencies were issued. The
    Federal government then filed a motion to quash the summonses
    sent to Federal authorities. The motion judge allowed the
    motion to quash, concluding that the defendant was instead
    required to follow the established Federal regulations to obtain
    records from a Federal agency. The defendant eventually
    petitioned for relief to a single justice of this court, which
    was denied. The defendant's subsequent appeal to the full court
    was also denied. Ayala v. Commonwealth, 
    454 Mass. 1015
    , 1015
    (2009).
    16
    to unsuccessfully request that the trial court judge compel
    Federal authorities to disclose this information.
    During the time period of the continuance, and while
    engaging in the pursuit of the federally held information, the
    defense had the opportunity to depose N.F.   At her deposition,
    N.F. testified to her status as a confidential informant for the
    Federal Bureau of Investigation (FBI), including the nature of
    her work and compensation.   She also testified to her
    observations on the morning of the shooting, which supported the
    defendant's theory that he was not present at the scene at the
    time of the shooting.   Specifically, N.F. testified that she
    witnessed the defendant driving away from the scene before the
    shooting took place, and instead implicated another individual
    whom she witnessed fleeing the scene.   The deposition also
    revealed that N.F. had telephoned a Federal agent on or about
    the morning of the shooting and described what had occurred.
    On the eve of trial, the defendant filed a motion to
    dismiss the case based on the Commonwealth's failure to turn
    over N.F.'s informant records.   The motion was eventually
    denied.   The defendant then sought once again to compel the
    testimony of a member of the Federal gang task force, but the
    subpoena was quashed.   Subpoenas for several other law
    enforcement officers and an assistant United States attorney
    were similarly quashed.   After these subpoenas had been quashed
    17
    and the trial was set to begin, at the suggestion of the trial
    judge, the defendant finally submitted a request to Federal
    authorities for the informant records in compliance with the
    governing Federal regulations described above.    Redacted copies
    of these records were disclosed to the defendant a few days
    later, before the defense had rested its case.    These records
    effectively confirmed N.F's status as a confidential Federal
    informant and included a summary of a statement made by N.F. to
    a Federal law enforcement officer regarding the shooting.      The
    Federal government also authorized two law enforcement officers
    to testify on a limited basis.
    b.   Analysis.   The due process clauses of the Federal
    Constitution and the Massachusetts Declaration of Rights require
    that the Commonwealth disclose material, exculpatory evidence to
    the defendant.15   Committee for Pub. Counsel Servs. v. Attorney
    Gen., 
    480 Mass. 700
    , 731 (2018).   See Brady v. Maryland,

    , 87 (1963); Commonwealth v. Donahue, 
    396 Mass. 590
    , 596
    15For the purposes of our analysis, we assume, without in
    any way deciding, that the information that would confirm N.F.'s
    status as an informant falls within the scope of what is
    considered exculpatory information. See Commonwealth v.
    Williams, 
    455 Mass. 706
    , 714 n.6 (2010) ("[E]xculpatory is not a
    technical term meaning alibi or other complete proof of
    innocence, but simply imports evidence which tends to negate the
    guilt of the accused . . . or, stated affirmatively, supporting
    the innocence of the defendant" [quotations omitted]);

    Donahue, supra
    ("The prosecutor cannot be
    said to suppress that which is not in his possession or subject
    to his control").
    The information related to N.F.'s status as a confidential
    informant was not in the Commonwealth's possession or control,
    but rather was in the possession and control of the Federal
    government.   There is no contention, nor is there any evidence,
    that any member of the Federal government or the Federal gang
    task force assisted in the investigation or prosecution of the
    defendant's case.     The records held by the task force therefore
    cannot be said to have been in the possession or control of the
    Commonwealth.   See Commonwealth v. Beal, 
    429 Mass. 530
    , 532
    (1999).   The Commonwealth was therefore under no obligation to
    turn over this information.     See 
    id. ("The prosecutor's
    duty
    does not extend beyond information held by agents of the
    prosecution team"); 
    Donahue, 396 Mass. at 596-597
    .
    Although we do not charge the Commonwealth with the
    obligation to disclose exculpatory information that it does not
    possess or control, we have recognized that issues of Federal
    and State sovereignty have the potential to prejudice a
    defendant being prosecuted in State court by stymying his or her
    ability to obtain exculpatory information held by Federal
    19
    authorities.   
    Donahue, 396 Mass. at 598
    .      See Commonwealth v.
    Liebman, 
    379 Mass. 671
    , 674 (1980), S.C., 
    388 Mass. 483
    (1983).
    Accordingly, under certain circumstances we will require the
    Commonwealth to bear the burden of securing the cooperation of
    the Federal government with regard to the disclosure of
    exculpatory information.     
    Donahue, supra
    .   See Commonwealth v.
    Lykus, 
    451 Mass. 310
    , 327 (2008); Liebman, supra at 675.
    Imposing this burden serves to guard against any potential
    unfairness to a defendant that may arise due to the presence of
    two sovereigns.   See Lykus, supra at 328; Liebman, supra at 674.
    A determination whether the Commonwealth bears this burden
    requires us to apply the four-factor analysis set forth in
    
    Donahue, 396 Mass. at 599
    .    We evaluate "[(i)] the potential
    unfairness to the defendant; [(ii)] the defendant's lack of
    access to the evidence; [(iii)] the burden on the prosecutor of
    obtaining the evidence; and [(iv)] the degree of cooperation
    between State and Federal authorities, both in general and in
    the particular case."   
    Id. Applying the
    above analysis to this
    case, we conclude that each factor weighs against imposing the
    burden on the Commonwealth to secure the release of information
    related to N.F.'s status as a confidential Federal informant.
    Under the first Donahue factor, we discern no unfairness to
    the defendant as a result of not receiving this information.
    Cf. 
    Donahue, 396 Mass. at 599
    -600.    As a threshold matter, we
    20
    note that N.F.'s status as an informant was not withheld or
    otherwise hidden from the defendant in any way.    The
    Commonwealth disclosed her status to the defendant, and defense
    counsel had the opportunity to depose N.F. to uncover the full
    nature of her relationship with the FBI.   The defendant sought
    the informant records and corroborative testimony from Federal
    officers, however, for the sole purpose of establishing N.F.'s
    credibility as a witness in front of the jury.    At trial, the
    judge permitted the defendant to admit N.F.'s status in evidence
    through her testimony.   That status was not in any way
    contested.   The judge ruled that he would not permit any
    additional evidence -- whether through documents or additional
    testimony -- detailing her work as an informant that would
    amount to vouching for her credibility.    See United States v.
    Piva, 
    870 F.2d 753
    , 760 (1st Cir. 1989) (noting
    inappropriateness of use of government officials to vouch for
    credibility of their informants because evaluation of
    informant's credibility is up to jury).    On direct examination,
    N.F. testified that she was indeed an informant and that she had
    worked as an informant for approximately two years and had been
    paid by Federal authorities on multiple occasions.   N.F. also
    testified extensively about her observations on the morning of
    the shooting and forcefully denied any involvement by the
    defendant in the shooting.   Accordingly, the information the
    21
    defense sought to use to establish N.F.'s status as an informant
    was cumulative of her uncontested testimony on this issue.       The
    cumulative nature of the information was confirmed on the last
    day of trial when a redacted copy of N.F.'s informant records
    was produced to the defendant.     The information contained in the
    unredacted portions of the records, at most, confirmed N.F.'s
    status as an informant and revealed a summary of the statement
    that she gave to a Federal agent concerning the shooting.       This
    information was fully developed during N.F.'s deposition and at
    trial.   Additionally, the officers whose testimony the defendant
    sought to compel were only authorized to testify on a limited
    basis and were not permitted to disclose the identities of
    confidential informants.     The only arguably new information
    contained in the disclosed records included a reference to a
    separate individual, whom she named, as the shooter.     This
    individual's alleged presence at the scene of the crime,
    however, was disclosed to the defense over one year earlier when
    the Commonwealth disclosed to the defendant that N.F. was an
    informant.     The potential involvement of a third party in the
    shooting was also revealed by N.F. during her deposition.
    Despite this knowledge, defense counsel chose not to question
    N.F. about this individual's involvement during direct
    examination.    The remaining portions of the records were
    redacted pursuant to Federal guidelines.     To the extent that the
    22
    defendant argues that he was entitled to the disclosure of the
    unredacted portions of the file, he is mistaken.   The defendant
    has not produced any evidence that the redacted portions of the
    file contained any relevant, let alone exculpatory, information.
    See Commonwealth v. Healy, 
    438 Mass. 672
    , 679 (2003) ("To
    prevail on a claim that the prosecution failed to disclose
    exculpatory evidence, the defendant must first prove that the
    evidence was, in fact, exculpatory").   The defendant was
    therefore not prejudiced by his inability to obtain this
    information before trial.   See Commonwealth v. Vieira, 
    401 Mass. 828
    , 838 (1988) (no prejudice where substance of withheld
    evidence was cumulative of information already known to
    defendant).
    On appeal, the defendant also argues that he was prejudiced
    by the failure to have this information at trial because it was
    needed to rehabilitate N.F.'s credibility after she contradicted
    her own testimony with regard to how long she was an informant.
    Specifically, after testifying on direct examination that she
    was an informant for at least two years and had been paid by the
    Federal government on multiple occasions, she testified on
    cross-examination that she had only been paid once.16   This
    16The defendant argued that the change in her testimony was
    the result of intimidation on the part of the Federal government
    and moved for a mistrial on that basis. The motion was denied.
    There was no evidence that Federal officers intimidated N.F.
    23
    contradiction did not put her status as a confidential informant
    in doubt, however, just the length of time that she was an
    informant and on how many occasions she was paid by Federal
    authorities -- both issues tangential to the case.    We do not
    believe that the defendant's access to the Federal records and
    testimony on N.F.'s informant status was therefore necessary to
    rehabilitate her credibility for these purposes, and instead may
    have presented other problems for the defense.     Indeed,
    admitting additional evidence on the length of time that she was
    an informant after her testimony on cross-examination concluded
    may very well have further undermined her credibility.       The
    fairness concerns present in other cases involving issues of
    dual sovereignty are therefore not present here.    See, e.g.,
    
    Donahue, 396 Mass. at 599
    -600.
    into lying or otherwise changing her testimony at trial. The
    only evidence presented was that N.F. was told that a Federal
    officer was upset with her participation in the defendant's
    case, that she would not be paid again until after the trial
    ended, and that she was not to detail her payments or the
    information that she had given Federal officers in the past.
    This is not sufficient to show that she was intimidated into
    altering her testimony. Indeed, the defendant's theory of
    intimidation is belied by the fact that the purported
    intimidation allegedly occurred before N.F. testified in the
    case. Had she been intimidated as the defendant argues, one
    would not have expected her to testify to being an informant for
    approximately two years and receiving payments as she did on
    direct examination. Accordingly, this theory does not support
    the defendant's contention that he was prejudiced by the failure
    to obtain the federally held information of N.F.'s status as an
    informant.
    24
    The second Donahue factor considers the defendant's lack of
    access to the sought-after evidence.   Here, we conclude that
    this factor weighs heavily against imposing the burden on the
    Commonwealth to secure the disclosure of this information.      The
    defendant was given an opportunity to depose N.F prior to trial.
    The record makes clear that the defendant also had ample time
    and opportunity to obtain the informant records and the
    substance of the sought-after testimony well before trial.
    Approximately eleven months before trial took place, the
    defendant was advised that obtaining this information from
    Federal authorities would require that he pursue it in
    accordance with Federal regulations.   Indeed, he was reminded of
    the federally mandated procedure described several times,
    including by this court.   See Ayala v. Commonwealth, 
    454 Mass. 1015
    , 1015 n.2 (2009) (noting that defendant "may have other
    means at his disposal to obtain the information he seeks.     The
    Federal agencies have indicated that they would consider a
    request submitted by the defendant pursuant to [Federal
    regulations]").   See also United States ex rel. Touhy v. Ragen,
    
    340 U.S. 462
    , 468 (1951) (upholding Federal regulation
    restricting ability of Federal authorities to disclose
    subpoenaed information).   He did not, however, avail himself of
    the opportunity to obtain this information through the Federal
    procedure.   Instead, he engaged in a year-long campaign to
    25
    compel this information through State proceedings.      The
    defendant had a full and fair opportunity to retrieve this
    evidence months before trial, but chose not to.    Indeed, when he
    finally did comply with the Federal procedures at the start of
    the trial, he received a redacted copy of N.F.'s informant
    records and a notice authorizing the testimony of two Federal
    officers a few days later.
    The third Donahue factor requires us to evaluate the burden
    on the prosecutor in obtaining the withheld information.       Under
    this factor, we consider whether the prosecutor has a means of
    access to the information held by Federal authorities that the
    defendant does not.    See 
    Donahue, 396 Mass. at 600
    .   Here, the
    prosecutor would have been required to comply with the Federal
    procedure as well.17   This case is therefore distinguishable from
    cases where the burden on the prosecution to retrieve the
    withheld information was minimal compared to the defendant.        See
    
    id. (noting that
    while exculpatory information could not be
    obtained by defendant, it "may well have been available to the
    prosecutor on request").     There is no evidence in this case that
    a request from the Commonwealth, rather than from the defendant,
    would have precipitated the disclosure of the evidence.       In
    17During argument before the start of trial, defense
    counsel conceded that the prosecutor in this case "ha[d] done
    whatever she could to procure evidence that is of exculpatory
    nature."
    26
    fact, the record reveals the opposite.   In response to discovery
    requests issued by the defendant that sought to determine
    whether other individuals at the party were also Federal
    informants, the prosecutor submitted requests for information
    related to these individuals in compliance with the Federal
    regulations.    Rather than disclose this information, the FBI
    curtly informed the prosecutor that it "decline[d] either to
    confirm or deny whether [an individual] is or was an informant
    for the FBI."   The burden on the prosecution was thus comparable
    to that on the defendant.
    The fourth and final Donahue factor considers the degree of
    cooperation between State and Federal authorities, both in
    general and in the particular case.    Where the cooperation
    between the two sovereigns is particularly strong, such as in a
    joint investigation of a defendant, we have determined that
    fairness dictates that the burden of securing the disclosure of
    the information held by Federal authorities falls squarely on
    the Commonwealth.   See 
    Lykus, 451 Mass. at 328
    .   Here, however,
    there is no evidence of any cooperation between State and
    Federal authorities in the investigation or prosecution of the
    defendant's case.   Although there was evidence that several
    Springfield police officers were deputized as Federal officers
    for the purposes of operating within the Federal gang task
    force, there was nothing to suggest that these officers played
    27
    any role in the defendant's case.     Because this case did not
    fall within the umbrella of matters under investigation by the
    task force, it cannot be said that the FBI "functioned as [an]
    agent[]" of the Commonwealth in this case.     
    Donahue, 396 Mass. at 599
    .
    After weighing these factors, we conclude that the
    Commonwealth was not required to bear the burden of securing the
    release of the information concerning N.F.'s status as an
    informant from Federal authorities.     The defendant was not
    prejudiced by the nondisclosure, the defendant had ample
    opportunity to depose the informant and retrieve this
    information on his own, the Commonwealth would have been
    required to follow the same Federal procedures as the defendant
    to access the information, and the Federal government played no
    role in the investigation or prosecution of the defendant's
    case.   See 
    Lykus, 451 Mass. at 328
    ; 
    Donahue, 396 Mass. at 598
    ;
    
    Liebman, 379 Mass. at 675
    .   The trial judge therefore did not
    abuse his discretion in declining to require the Commonwealth to
    secure N.F.'s informant records from Federal authorities and in
    declining to compel the testimony of Federal law enforcement
    officers.
    3.   Ineffective assistance of counsel.    Following his
    convictions, the defendant filed a motion for a new trial,
    arguing that his trial counsel had been ineffective.     The motion
    28
    advanced a litany of errors alleged to have been made by trial
    counsel.   Relevant to this appeal, the motion judge, who was not
    the trial judge, allowed an evidentiary hearing on trial
    counsel's failure to retain and call experts on eyewitness
    identification and ballistics.   The motion judge did not allow
    an evidentiary hearing, however, on trial counsel's failure to
    notice the absence of Perez's psychological records that were
    subject to disclosure after finding that the defendant had not
    raised a substantial issue warranting further hearing.
    Following the evidentiary hearing, the motion judge denied the
    defendant's motion for a new trial.
    On appeal, the defendant argues that the motion judge erred
    in denying his motion with respect to his arguments that his
    trial counsel was ineffective for (i) failing to retain and call
    an expert witness on the accuracy of eyewitness identifications,
    (ii) failing to retain and call an expert witness on ballistics
    evidence to testify about muzzle flashes, and (iii) failing to
    notice the absence of medical records that provided further
    insight into Perez's mental health issues and drug use.
    Because the defendant was convicted of murder in the first
    degree, we do not evaluate his ineffective assistance claim
    under the traditional standard set forth in Commonwealth v.
    29
    Saferian, 
    366 Mass. 89
    , 96 (1974).18     See Commonwealth v. Seino,
    
    479 Mass. 463
    , 472 (2018); Commonwealth v. Kolenovic, 
    478 Mass. 189
    , 192-193 (2017).    Instead, we apply the more favorable
    standard of G. L. c. 278, § 33E, and review his claim to
    determine whether there was a substantial likelihood of a
    miscarriage of justice.    
    Seino, supra
    .    Under this review, we
    first ask whether defense counsel committed an error in the
    course of the trial.    
    Id. If there
    was an error, we ask whether
    it was likely to have influenced the jury's conclusion.       
    Id. at 472-473.
    Where the claimed ineffectiveness is the result of a
    strategic or tactical decision of trial counsel, the decision
    must have been "manifestly unreasonable" to be considered an
    error.    
    Kolenovic, 478 Mass. at 193
    .     Commonwealth v. Holland,
    
    476 Mass. 801
    , 812 (2017).    A determination on whether a
    decision is manifestly unreasonable requires an evaluation of
    the "decision at the time it was made" (citation omitted).
    
    Holland, supra
    .   Only strategic and tactical decisions "which
    lawyers of ordinary training and skill in criminal law would not
    18Under Commonwealth v. Saferian, 
    366 Mass. 89
    , 96–97
    (1974), the standard is whether an attorney's performance fell
    "measurably below that which might be expected from an ordinary
    fallible lawyer" and, if so, whether such ineffectiveness has
    "likely deprived the defendant of an otherwise available,
    substantial ground" of defense.
    30
    consider competent are manifestly unreasonable" (citation
    omitted).   
    Id. We conclude
    that any errors by the defendant's trial
    counsel did not create a substantial likelihood of a miscarriage
    of justice.    The defendant's motion for a new trial was
    therefore properly denied.    We address each of the defendant's
    arguments in turn.
    a.   Eyewitness identification expert.    The defendant's
    motion for a new trial relied heavily on trial counsel's failure
    to obtain evidence from an expert on eyewitness identification.
    Had an expert been called, the defendant argues, the jury would
    have heard evidence on the variables that affect eyewitness
    identifications and would have had "further reason to doubt the
    reliability of Perez's identification."   Specifically, the
    defendant claims that an eyewitness identification expert would
    have testified to the theory of "transference," which suggests
    that Perez identified the defendant as the shooter only because
    of his earlier observations of the defendant during his
    altercation with the bouncers.    Additionally, the defendant
    contends that the expert would have testified to "the negative
    effects on accuracy of heightened stress and post-identification
    feedback," the "weak correlation of confidence to accuracy" of
    the identification, and the "chance of error by a single
    eyewitness."
    31
    The decision to call, or not to call, an expert witness
    fits squarely within the realm of strategic or tactical
    decisions.   See, e.g., Commonwealth v. Facella, 
    478 Mass. 393
    ,
    413 (2017) (decision not to call psychiatric expert reasonable
    strategic decision); Commonwealth v. Hensley, 
    454 Mass. 721
    , 739
    (2009) (decision not to call expert strategic).   Accordingly, we
    evaluate whether the decision was "manifestly unreasonable" at
    the time it was made.19   
    Holland, 476 Mass. at 812
    .
    We cannot say that trial counsel's decision not to call an
    expert on eyewitness identification was manifestly unreasonable
    when it was made.   At the evidentiary hearing, trial counsel
    testified that at the time of trial, he believed that N.F's
    testimony that the defendant was not at the scene at the time of
    the shooting, the inconsistencies of Perez's eyewitness account,
    19The defendant contends on appeal that the motion judge
    incorrectly found that the failure to call an expert was a
    strategic decision. The defendant's trial counsel offered
    contradictory testimony on this point at the evidentiary
    hearing. In his affidavit, and on direct examination, trial
    counsel claimed that the failure to call an expert was not a
    strategic decision. Trial counsel testified that, rather, he
    simply never considered whether to call one. On cross-
    examination, however, he testified that he made the
    determination that an identification expert was not relevant to
    the case. Given this conflicting testimony, we see no reason to
    disturb the motion judge's conclusion that not calling an expert
    on eyewitness identification was a part of the larger strategic
    decision to focus the defense on the testimony of N.F. and the
    cross-examination of Perez. Commonwealth v. Perkins, 
    450 Mass. 834
    , 845 (2008) ("[W]e defer to [the motion] judge's assessment
    of the credibility of witnesses at the hearing on the new trial
    motion" [citation omitted]).
    32
    and Perez's mental health struggles would be sufficient to
    challenge the reliability of Perez's identification.    To that
    end, trial counsel attacked Perez's identification of the
    defendant as the shooter, both on cross-examination and during
    closing argument.   On cross-examination, trial counsel
    confronted Perez on his ability to accurately identify the
    shooter under the lighting conditions at the time of the
    shooting, his recollection of certain events that morning, and
    the discrepancies between Perez's statement to police on the
    morning of the shooting and his trial testimony regarding the
    defendant's height and clothing worn.     Additionally, the defense
    presented evidence that Perez suffered from PTSD as a result of
    his military service and bipolar disorder.     Specifically, trial
    counsel introduced evidence that Perez had sought counselling
    for his mental health struggles approximately 161 times over an
    eight-year period and that he began taking medication for these
    issues a few months after the shooting.    Finally, during closing
    argument, trial counsel argued that Perez's identification was
    unreliable.   He argued that in light of Perez's mental health
    struggles, the "collective experience" of the jurors could lead
    them to conclude that "those are difficult illnesses and they
    may impact his ability to see and conceptualize what was
    actually happening."   He also argued that Perez had made a
    mistaken identification.
    33
    The reliability of Perez's identification was vigorously
    challenged through this strategy.20   Cf. Commonwealth v. Watson,
    
    455 Mass. 246
    , 257-259 (2009) (decision not to seek funds for
    expert on eyewitness identification not manifestly unreasonable
    where reliability of identification challenged on cross-
    examination and in closing argument).   Accordingly, we cannot
    say that trial counsel's decision not to call an expert on
    eyewitness identification was one that "lawyers of ordinary
    training and skill in criminal law would not consider competent"
    (citation omitted).   
    Holland, 476 Mass. at 812
    .   See
    Commonwealth v. Kolenovic, 
    471 Mass. 664
    , 674 (2015), S.C., 
    478 Mass. 189
    (2017) ("[R]easonableness does not demand
    20We also note that, as the motion judge concluded, at the
    time of trial in 2009, the retention of experts on eyewitness
    identification was not as prevalent as it is today. See
    Commonwealth v. Holland, 
    476 Mass. 801
    , 812 (2017) ("[We] make
    every effort . . . to eliminate the distorting effects of
    hindsight" in evaluating whether decision is manifestly
    unreasonable [quotation and citation omitted]). Indeed, trial
    counsel testified that he had never retained an expert on
    eyewitness identification, despite having decades of experience
    as an attorney and having tried over forty murder cases. At the
    time of trial, counsel had the benefit of neither the Report and
    Recommendations of the Supreme Judicial Court Study Group on
    Eyewitness Evidence (July 25, 2013) nor our decision in
    Commonwealth v. Gomes, 
    470 Mass. 352
    , 354, 363-364 (2015), that
    highlighted the preference for expert testimony or, in the
    absence of such testimony, specific jury instructions regarding
    the reliability of eyewitness identifications. Finally, Perez
    clearly identified the defendant correctly as the person who
    threatened to come back and "light" the party "up" when he was
    removed. The primary issue of identification related to the
    transference theory.
    34
    perfection. . . .   Nor is reasonableness informed by what
    hindsight may reveal as a superior or better strategy").
    Accordingly, the decision was not manifestly unreasonable at the
    time it was made.
    b.   Ballistics expert.   The defendant also argues that his
    trial counsel was ineffective for failing to call a ballistics
    expert who would testify that a muzzle flash fired from a
    semiautomatic handgun was unlikely to provide sufficient
    illumination to allow an individual to adequately see the face
    of the shooter.   We need not decide whether the decision not to
    call a ballistics expert was a manifestly unreasonable one
    because, even assuming that it was, we conclude that it was not
    likely to have influenced the jury's conclusion.   See 
    Seino, 479 Mass. at 472-473
    .
    As we discussed in 
    depth supra
    , there was a significant
    amount of independent evidence establishing that the crime scene
    was illuminated at the time of the shooting.   For example, a
    police officer testified that the street lights near the
    location of the shooting and the exterior lights on a nearby
    building were illuminated when he arrived at the crime scene at
    approximately 4:30 A.M. -- only approximately one and one-half
    to two hours after the shooting occurred.   Additionally, the
    jury heard evidence that suggested the area in front of the home
    was illuminated enough to permit N.F. and Perez to independently
    35
    identify the defendant from the porch on the second floor while
    the defendant was standing on the street outside.    Even assuming
    that an expert would have testified that Perez was unlikely to
    have been able to see the shooter solely from the muzzle flash,
    the jury were not likely to have been influenced by this
    testimony in light of the other evidence that the crime scene
    was lit at the time of the shooting.     Accordingly, we conclude
    that any error in failing to call a ballistics expert did not
    create a substantial likelihood of a miscarriage of justice.
    c.      Evidence of mental health struggles and drug use.
    Finally, the defendant argues that his trial counsel was
    ineffective for failing to notice that certain psychological
    records detailing Perez's history of mental health struggles and
    drug use mistakenly had been withheld despite a court order
    compelling their disclosure.    Without these records, the
    defendant argues, trial counsel was unable to explore the full
    extent of how Perez's mental health and drug use could have
    affected his "ability to accurately perceive and identify the
    shooter."     The motion judge denied the defendant's motion for a
    new trial without conducting an evidentiary hearing on this
    argument.    He concluded that because these issues were
    sufficiently before the jury, the additional records would not
    have "added to the information already at [trial counsel's]
    disposal and used in cross-examination at trial."    We agree.
    36
    As 
    discussed supra
    , Perez's PTSD and bipolar disorder
    diagnoses were both brought out on cross-examination at trial.
    Specifically, Perez testified that he had been diagnosed with
    PTSD and bipolar disorder, that he received counselling and
    medication to treat the diagnoses, and that he had had a
    counselling session on the day after the murder.   He further
    testified that over the period of approximately eight years
    following his discharge from the military, he had sought
    counselling for his PTSD 161 times and that he suffered from
    "night terror[s]" and sleeplessness as a result of his PTSD.21
    Additionally, he testified that he used marijuana to cope with
    the effects of his PTSD diagnosis.
    Notably, there was no evidence -- either introduced at
    trial or contained within the missing records -- that suggests
    that Perez's mental health struggles or drug use affected his
    ability to perceive the defendant on the morning of the
    shooting.   For example, a defense expert's proffered testimony
    21At the evidentiary hearing on the defendant's motion for
    a new trial, trial counsel testified that, at the time of the
    trial, he believed it would have been a poor tactical choice to
    "attack" Perez in front of the jury, given that Perez was a
    veteran suffering from posttraumatic stress disorder (PTSD).
    Therefore, it is unlikely that trial counsel would have used the
    information in the missing records to further attack Perez's
    ability to perceive the shooter due to his PTSD diagnosis even
    if counsel had them. See Commonwealth v. Duran, 
    435 Mass. 97
    ,
    106 (2001) (rejecting claim that counsel was ineffective for
    failing to "attempt to use every conceivable method" to impeach
    sympathetic witness).
    37
    only acknowledged that Perez's mental health struggles "had the
    potential to and may have interfered with Mr. Perez's abilities
    to accurately perceive or recollect the [shooting]."   Trial
    counsel argued this point specifically during closing, stating
    that Perez's diagnoses "are difficult illnesses and they may
    impact his ability to see and conceptualize what was actually
    happening."   Additionally, although the missing records
    suggested that Perez was more dependent on marijuana than his
    testimony let on, there was no evidence that he was under the
    influence of marijuana on the morning of the shooting.     The
    defendant's proffered expert on this point would not have
    materially added to the defense, as he was prepared only to
    testify that individuals have a reduced ability to accurately
    perceive reality and recall past events while under the
    influence of mind-altering substances.   Because the substance of
    the missing records and proffered expert testimony was already
    presented to the jury, any error on the part of trial counsel in
    failing to notice the missing records was not likely to
    influence the jury's conclusion.   See Commonwealth v. Williams,
    
    453 Mass. 203
    , 212-213 (2009) (rejecting ineffective assistance
    of counsel claim based on counsel's failure to introduce records
    where substance of records was already before the jury).    The
    motion judge therefore did not err in denying the defendant's
    motion for a new trial.
    38
    4.    Review under G. L. c. 278, §33E.   After a thorough
    review of the record, we find no reason to exercise our
    authority under G. L. c. 278, § 33E, to grant a new trial or to
    reduce or set aside the verdict of murder in the first degree.
    Pursuant to this duty, however, we deem it necessary to address
    one of the arguments raised by the defendant during the motion
    for a new trial, but not raised on appeal.
    In his motion for a new trial, the defendant argued that
    his trial counsel's failure to request an "honest but mistaken
    identification" jury instruction constituted ineffective
    assistance of counsel.      This instruction arose from our decision
    in Commonwealth v. Pressley, 
    390 Mass. 617
    , 620 (1983), wherein
    we declared that "[f]airness to a defendant compels the trial
    judge to give an instruction on the possibility of an honest but
    mistaken identification" where identification was "crucial to
    the Commonwealth's case."     We held that this instruction must be
    given "when the facts permit it and when the defendant requests
    it."   
    Id. Here, the
    facts permitted such an instruction.   The
    defendant did not, however, request it.      We therefore review to
    determine if this error produced a substantial likelihood of a
    miscarriage of justice.      Commonwealth v. Penn, 
    472 Mass. 610
    ,
    625-626 (2015).     We conclude that it did not.
    As the motion judge concluded, the trial judge described
    various factors that the jury should consider in assessing the
    39
    identification evidence and "made clear that the jurors must be
    satisfied beyond a reasonable doubt of the accuracy of the
    identification of [the defendant] before they could convict
    him."    Moreover, the defendant's trial counsel specifically
    argued mistaken identification in closing and cross-examined
    Perez on his ability to accurately perceive the shooter.
    Accordingly, "we are substantially confident that, if the error
    had not been made, the jury verdict would have been the same"
    (citation omitted).    
    Penn, 472 Mass. at 626
    .   Cf. 
    id. at 625-626
    (no likelihood of substantial miscarriage of justice where
    honest mistake was focus of defendant's cross-examination of
    eyewitness and closing argument).    We therefore conclude that
    trial counsel's failure to request the "honest but mistaken
    identification" instruction did not create a substantial
    likelihood of a miscarriage of justice.
    Conclusion.    For these reasons, we affirm the defendant's
    convictions and the denial of the defendant's motion for a new
    trial.
    So ordered.
