    BRYAN JORDAN v. COMMISSIONER
    OF CORRECTION
    (AC 42250)
    Lavine, Prescott and Sheldon, Js.
    Syllabus
    The petitioner, who previously had been convicted of the crimes of man-
    slaughter in the first degree with a firearm and carrying a pistol or
    revolver without a permit, sought a writ of habeas corpus, claiming that
    his trial counsel, D, provided ineffective assistance. He claimed, inter
    alia, that D was deficient in failing to adequately investigate and present
    available witnesses in support of his claim of self-defense and by failing
    to raise the defense of third-party culpability. D died prior to the petition-
    er’s habeas trial and, thus, the habeas trial did not hear testimony regard-
    ing D’s investigative efforts, trial strategy, or other tactical decisions.
    The habeas court rendered judgment granting the habeas petition, from
    which the respondent, the Commissioner of Correction, on the granting
    of certification, appealed to this court. Held:
    1. The habeas court improperly concluded that D provided constitutionally
    deficient representation with regard to the petitioner’s self-defense
    claim: the petitioner failed to meet his burden of demonstrating that
    D’s investigation or decision not to call certain witnesses constituted
    deficient performance as he failed to present testimony regarding D’s
    investigative efforts and, thus, failed to overcome the strong presumption
    that D engaged in an objectively reasonable investigation, and he failed
    to present any evidence regarding D’s trial strategy and, thus, failed to
    overcome the presumption that any decision not to call certain witnesses
    was sound trial strategy; furthermore, the habeas court’s conclusion
    that the witnesses who testified at the habeas trial were credible and
    could have lent additional support to the petitioner’s claim of self-
    defense was premature in the absence of a determination that D’s perfor-
    mance was deficient.
    2. The habeas court improperly determined that D provided ineffective
    assistance because she failed to pursue a third-party culpability defense:
    the court failed to consider whether D’s decision might be viewed as a
    reasonable strategic decision and the petitioner failed to present evi-
    dence that this decision constituted deficient performance; the record
    was clear that, although D did not request a third-party culpability
    instruction, she did argue to the jury that the victim was killed by a
    bullet fired by someone other than the petitioner, and there were a
    number of reasons why D may have chosen to present the third-party
    culpability defense in this manner.

    Procedural History
    Amended petition for a writ of habeas corpus,
    brought to the Superior Court in the judicial district
    of Tolland and tried to the court, Kwak, J.; judgment
    granting the petition, from which the respondent, on
    the granting of certification, appealed to this court.
    Reversed; judgment directed.
    James A. Killen, senior assistant state’s attorney,
    with whom, on the brief, were Patrick J. Griffin, state’s
    attorney, and Rebecca A. Barry, supervisory assistant
    state’s attorney, for the appellant (respondent).
    Daniel J. Krisch, assigned counsel, for the appel-
    lee (petitioner).
    Opinion
    PRESCOTT, J. This appeal highlights the significant
    hurdle a habeas corpus petitioner faces in seeking to
    prove a claim of ineffective assistance of trial counsel
    after trial counsel has died and, thus, is unavailable to
    provide evidence of counsel’s strategic decisions
    regarding, inter alia, the pursuit of defenses for her
    client and calling witnesses in support of those
    defenses. The death of the petitioner’s trial counsel
    prior to a habeas corpus trial, however, does not absolve
    a petitioner of his heavy burden of overcoming the
    strong presumption that counsel provided effective
    assistance. See Strickland v. Washington, 
    466 U.S. 668
    ,
    689, 
    104 S. Ct. 2052
    , 
    80 L. Ed. 2d 674
     (1984); see also
    Slevin v. United States, 
    71 F. Supp. 2d 348
    , 358 n.9
    (S.D.N.Y. 1999) (‘‘[b]ecause the death of a petitioner’s
    trial counsel is just as, if not more, likely to prejudice
    the respondent, it does not relieve the petitioner of his
    heavy burden of proving ineffective assistance’’ (inter-
    nal quotation marks omitted)), aff’d, 
    234 F.3d 1263
     (2d
    Cir. 2000).
    The respondent, the Commissioner of Correction,
    appeals from the judgment of the habeas court granting
    a petition for a writ of habeas corpus filed by the peti-
    tioner, Bryan Jordan. The respondent claims on appeal
    that the habeas court improperly determined that the
    petitioner’s trial counsel rendered ineffective legal
    assistance by failing to investigate adequately and to
    present available witnesses in support of the petition-
    er’s claim of self-defense and, alternatively, by failing
    to raise the defense of third-party culpability. We agree
    with the respondent that the habeas court failed to
    hold the petitioner to the requisite burden of proof and,
    accordingly, reverse the judgment of the habeas court.
    In the underlying criminal matter, the petitioner was
    charged with murder in violation of General Statutes
    § 53a-54a (a) and carrying a pistol or revolver without
    a permit in violation of General Statutes § 29-35. A jury
    found the petitioner not guilty of murder, but guilty of
    the lesser included offense of manslaughter in the first
    degree with a firearm in violation of General Statutes
    § 53a-55a (a). The jury also found the petitioner guilty
    of carrying a pistol or revolver without a permit. The
    court sentenced the petitioner to a total effective sen-
    tence of forty-five years of imprisonment.1
    This court briefly summarized the facts underlying
    the petitioner’s criminal conviction in its opinion
    affirming the judgment of conviction. See State v. Jor-
    dan, 
    117 Conn. App. 160
    , 161 
    978 A.2d 150
    , cert. denied,
    
    294 Conn. 904
    , 
    982 A.2d 648
     (2009). ‘‘The charges in this
    case stem from the shooting death of Curtis Hannons
    [(victim)] on September 19, 2005. On the day of the
    shooting, the [petitioner], the victim and the victim’s
    brother, [Jason Kelly, also known as Mookie] got into
    an argument. After the argument was broken up, the
    [petitioner] got into his car and left. A few minutes later,
    the [petitioner] returned, and another heated discussion
    took place with the victim. Several people congregated
    near the two and tried to calm down the [petitioner]
    and the victim. Three eyewitnesses gave slightly varying
    accounts of what happened next. All agreed that they
    heard a gunshot and that the [petitioner] then pulled
    out a gun and shot the victim once in the head. The
    [petitioner] ran away, and the witnesses heard about
    six or seven more gunshots. The victim was transported
    to a hospital, where he died. The [petitioner] was
    arrested in Georgia some time later.’’ (Internal quota-
    tion marks omitted.) 
    Id.,
     161–62.
    On direct appeal, this court rejected the petitioner’s
    claims that prosecutorial improprieties that occurred
    during the state’s closing argument had deprived him
    of a fair trial2 and that the trial court improperly had
    precluded him from presenting evidence regarding ille-
    gal drugs that were found on the victim. Id., 161, 170.
    In so concluding, this court indicated that ‘‘the state’s
    case [against the petitioner] was strong’’ and ‘‘[t]here
    was sufficient testimony for the jury to conclude that
    the [petitioner had not been] acting in self-defense
    . . . .’’ Id., 170.
    The petitioner filed the underlying petition for a writ
    of habeas corpus on February 11, 2015, which was his
    third habeas petition challenging his manslaughter con-
    viction.3 Appointed habeas counsel filed the operative
    eight count revised amended petition on September 26,
    2017. Count one alleged that the petitioner’s criminal
    trial counsel, Diane Polan, had provided ineffective
    assistance of counsel by failing to conduct a proper
    investigation and by failing to present available evi-
    dence supporting the petitioner’s assertion that he had
    shot the victim in self-defense. Count two alleged that
    Polan also had provided ineffective assistance by failing
    to impeach one of the state’s witnesses, Detective Clar-
    ence Willoughby, who had conducted the police investi-
    gation of the shooting. Count three alleged a Brady
    violation4 regarding the state’s alleged failure to disclose
    potential impeachment evidence pertaining to Wil-
    loughby. Count four alleged ineffective assistance of
    counsel by Polan premised on her failure to raise a
    third-party culpability defense. Count five alleged that
    Polan provided ineffective assistance of counsel with
    respect to an issue of alleged juror misconduct. Count
    six alleged a second Brady violation, this one premised
    on the state’s failure to correct allegedly false testimony
    by one of its witnesses. Count seven alleged that Polan
    provided ineffective assistance by failing to object to the
    prosecutorial impropriety that occurred during closing
    argument or to request a curative instruction with
    respect to that impropriety. Finally, count eight alleged
    that the state improperly failed to disclose evidence
    of pending criminal charges against one of the state’s
    witnesses. The respondent filed a return that left the
    petitioner to his proof on all counts of the petition.5
    The habeas court, Kwak, J., conducted a trial on
    January 22 and February 5, 2018. Significantly, the
    habeas court did not hear any testimony from Polan
    regarding her investigative efforts, trial strategy, and
    other tactical decisions because she had died prior to
    the habeas trial. Rather, the habeas court heard testi-
    mony from the petitioner and eight additional witnesses
    called on his behalf. Specifically, the petitioner elicited
    testimony from Polan’s former private investigator,
    Mike O’Donnell, and Attorney Robert McKay, who testi-
    fied as the petitioner’s expert witness on professional
    standards. The court also heard testimony from the
    following six witnesses, all of whom allegedly had wit-
    nessed events at or around the time of the shooting,
    but whom Polan did not call to testify at the criminal
    trial: Alexis Jordan, the petitioner’s niece; the petition-
    er’s sisters, Jymisha Freeman and Audrey Jordan;
    Flonda Jones, a friend of both the petitioner and the
    victim; James Walker, a relative of the victim; and Billy
    Wright, an acquaintance of both the petitioner and the
    victim. The court also admitted into evidence as full
    exhibits copies of the transcripts of the entire criminal
    trial. A written statement given by Jones to O’Donnell
    prior to the criminal trial also was admitted as a full
    exhibit.
    Following the habeas trial, both parties submitted
    posttrial briefs, and the petitioner filed a posttrial reply
    brief. In his posttrial brief, the petitioner withdrew
    counts three, five, six, and eight of his petition, electing
    to pursue only the remaining four counts, all of which
    alleged ineffective assistance by Polan as trial counsel.
    The habeas court issued a memorandum of decision
    on October 1, 2018, in which it granted the petition for
    a writ of habeas corpus on the basis of two of the four
    counts of ineffective assistance. Specifically, the habeas
    court determined that, with respect to counts one and
    four, the petitioner had met his burden of demonstrating
    that Polan had rendered constitutionally deficient per-
    formance by failing to investigate properly or to present
    available evidence in support of the petitioner’s claim
    of self-defense and by failing properly to investigate,
    raise, or present evidence in support of a third-party
    culpability defense. The habeas court further deter-
    mined that the petitioner had demonstrated that these
    deficiencies in counsel’s performance had prejudiced
    him by unduly diminishing his due process right to
    establish a defense. The habeas court rejected the peti-
    tioner’s other claims of ineffective assistance.6 The
    habeas court vacated the petitioner’s manslaughter con-
    viction and remanded the matter to the trial court for
    further proceedings. Following the granting of his peti-
    tion for certification to appeal,7 the respondent filed
    the present appeal. Additional facts will be set forth
    as needed.
    I
    We begin our discussion by setting forth guiding prin-
    ciples of law as well as our standard of review, which
    are well settled. ‘‘A criminal defendant’s right to the
    effective assistance of counsel extends through the first
    appeal of right and is guaranteed by the sixth and four-
    teenth amendments to the United States constitution
    and by article first, § 8, of the Connecticut constitution.
    . . .8 To succeed on a claim of ineffective assistance
    of counsel, a habeas petitioner must satisfy the two-
    pronged test articulated in Strickland v. Washington,
    
    [supra,
     
    466 U.S. 687
    ]. Strickland requires that a peti-
    tioner satisfy both a performance prong and a prejudice
    prong. To satisfy the performance prong, a claimant
    must demonstrate that counsel made errors so serious
    that counsel was not functioning as the counsel guaran-
    teed . . . by the [s]ixth [a]mendment.’’ (Citations omit-
    ted; footnote added; internal quotation marks omitted.)

    (2008). ‘‘To satisfy the prejudice prong, a claimant must
    demonstrate that there is a reasonable probability that,
    but for counsel’s unprofessional errors, the result of
    the proceeding would have been different. . . .
    Because both prongs . . . must be established for a
    habeas petitioner to prevail, a court may dismiss a peti-
    tioner’s claim if he fails to meet either prong.’’ (Internal

     (2017).
    On appeal, ‘‘[a]lthough the underlying historical facts
    found by the habeas court may not be disturbed unless
    they [are] clearly erroneous, whether those facts consti-
    tuted a violation of the petitioner’s rights [to the effec-
    tive assistance of counsel] under the sixth amendment
    is a mixed determination of law and fact that requires
    the application of legal principles to the historical facts
    of [the] case. . . . As such, that question requires ple-
    nary review by this court unfettered by the clearly erro-
    neous standard.’’ (Internal quotation marks omitted.)

    , 
    187 L. Ed. 2d 445
     (2013).
    Because our resolution of the present case turns on
    our review of the performance prong, some additional
    explication of that prong is necessary.9 ‘‘In any case
    presenting an ineffectiveness claim, the performance
    inquiry must be whether counsel’s assistance was rea-
    sonable considering all the circumstances. Prevailing
    norms of practice as reflected in American Bar Associa-
    tion standards and the like . . . are guides to determin-
    ing what is reasonable. . . . Nevertheless, [j]udicial
    scrutiny of counsel’s performance must be highly defer-
    ential. It is all too tempting for a defendant to second-
    guess counsel’s assistance after conviction or adverse
    sentence, and it is all too easy for a court, examining
    counsel’s defense after it has proved unsuccessful, to
    conclude that a particular act or omission of counsel
    was unreasonable. . . . A fair assessment of attorney
    performance requires that every effort be made to elimi-
    nate the distorting effects of hindsight, to reconstruct
    the circumstances of counsel’s challenged conduct, and
    to evaluate the conduct from counsel’s perspective at
    the time. Because of the difficulties inherent in making
    the evaluation, a court must indulge a strong presump-
    tion that counsel’s conduct falls within the wide range
    of reasonable professional assistance; that is, the [peti-
    tioner] must overcome the presumption that, under the
    circumstances, the challenged action might be consid-
    ered sound trial strategy. . . .
    ‘‘Thus, a court deciding an actual ineffectiveness
    claim must judge the reasonableness of counsel’s chal-
    lenged conduct on the facts of the particular case,
    viewed as of the time of counsel’s conduct. . . . At the
    same time, the court should recognize that counsel is
    strongly presumed to have rendered adequate assis-
    tance and made all significant decisions in the exercise
    of reasonable professional judgment. . . .
    ‘‘Inasmuch as [c]onstitutionally adequate assistance
    of counsel includes competent pretrial investigation
    . . . [e]ffective assistance of counsel imposes an obli-
    gation [on] the attorney to investigate all surrounding
    circumstances of the case and to explore all avenues
    that may potentially lead to facts relevant to the defense
    of the case. . . .
    ‘‘Nevertheless, strategic choices made after thorough
    investigation of law and facts relevant to plausible
    options are virtually unchallengeable; [but] strategic
    choices made after less than complete investigation
    are reasonable precisely to the extent that reasonable
    professional judgments support the limitations on
    investigation. In other words, counsel has a duty to
    make reasonable investigations or to make a reasonable
    decision that makes particular investigations unneces-
    sary. In any ineffectiveness case, a particular decision
    not to investigate must be directly assessed for reason-
    ableness in all the circumstances, applying a heavy mea-
    sure of deference to counsel’s judgments.
    ‘‘The reasonableness of counsel’s actions may be
    determined or substantially influenced by the [petition-
    er’s] own statements or actions. Counsel’s actions are
    usually based, quite properly, on informed strategic
    choices made by the [petitioner] and on information
    supplied by the [petitioner]. In particular, what investi-
    gation decisions are reasonable depends critically on
    such information. For example, when the facts that
    support a certain potential line of defense are generally
    known to counsel because of what the defendant has
    said, the need for further investigation may be consider-
    ably diminished or eliminated altogether. And when
    a defendant has given counsel reason to believe that
    pursuing certain investigations would be fruitless or
    even harmful, counsel’s failure to pursue those investi-
    gations may not later be challenged as unreasonable.
    . . .
    ‘‘Defense counsel will be deemed ineffective only
    when it is shown that a defendant has informed his
    attorney of the existence of the witness and that the
    attorney, without a reasonable investigation and with-
    out adequate explanation, failed to call the witness at
    trial. The reasonableness of an investigation must be
    evaluated not through hindsight but from the perspec-
    tive of the attorney when he was conducting it. . . .
    Furthermore, [t]he failure of defense counsel to call a
    potential defense witness does not constitute ineffec-
    tive assistance unless there is some showing that the
    testimony would have been helpful in establishing the
    asserted defense. . . .
    ‘‘Finally, our habeas corpus jurisprudence reveals
    several scenarios in which courts will not second-guess
    defense counsel’s decision not to investigate or call
    certain witnesses or to investigate potential defenses,
    such as when: (1) counsel learns of the substance of
    the witness’ testimony and determines that calling that
    witness is unnecessary or potentially harmful to the
    case; (2) the defendant provides some information, but
    omits any reference to a specific individual who is later
    determined to have exculpatory evidence such that
    counsel could not reasonably have been expected to
    have discovered that witness without having received
    further information from his client; or (3) the petitioner
    fails to present, at the habeas hearing, evidence or the
    testimony of witnesses that he argues counsel reason-
    ably should have discovered during the pretrial investi-
    gation.’’ (Citations omitted; emphasis added; footnotes

    ney’s performance fell below a constitutionally accept-
    able level of competence pursuant to the standards set
    forth herein, must ‘‘properly apply the strong presump-
    tion of competence that Strickland mandates’’ and is
    ‘‘required not simply to give [trial counsel] the benefit
    of the doubt . . . but to affirmatively entertain the
    range of possible reasons [that] counsel may have had
    for proceeding as [she] did.’’ (Citation omitted; empha-

    With the foregoing legal principles in mind, we turn to
    our discussion of the merits of the respondent’s claims
    on appeal.
    II
    The respondent first claims that the habeas court
    improperly determined that Polan rendered ineffective
    assistance of counsel with respect to the petitioner’s
    claim of self-defense. Specifically, the respondent
    argues that the habeas court’s determination that Polan
    failed to investigate adequately the shooting and to
    interview potential witnesses whose testimony could
    have supported the petitioner’s self-defense claim was
    wholly unsupported by the record presented. Further-
    more, the respondent argues that the habeas court
    never expressly considered if Polan may have had a
    reasonable and strategically sound basis for not calling
    certain witnesses, including Jones, as self-defense wit-
    nesses during the criminal trial and, to the extent that
    a negative answer to that question is implicit in the
    court’s ruling, neither the law nor the facts of this case
    supports it. We agree that the habeas court improperly
    concluded that Polan’s handling of the petitioner’s self-
    defense claim necessarily fell below the minimal consti-
    tutional standard required by the sixth amendment.
    A
    We first set forth the well settled substantive princi-
    ples underlying a defendant’s claim of self-defense. In
    Connecticut, self-defense is codified in General Statutes
    § 53a-19. ‘‘As interpreted by our Supreme Court, § 53a-
    19 (a) provides that a person may justifiably use deadly
    physical force in self-defense only if he reasonably
    believes both that (1) his attacker is using or about to
    use deadly physical force against him, or is inflicting
    or about to inflict great bodily harm, and (2) that deadly
    physical force is necessary to repel such attack.’’

    force if he or she knows that he or she can avoid the
    necessity of using such force with complete safety . . .
    by retreating.’’ General Statutes § 53a-19 (b) (1). ‘‘Thus,

    B
    We next discuss the state’s and the defense’s theories
    of the underlying criminal case, which are necessary
    to place our subsequent analysis in its proper context.
    At the criminal trial, the state advanced the following
    theory of the case to the jury during its closing argu-
    ment. The petitioner and the victim, who were acquain-
    tances, had become engaged in an argument in an area
    outside the housing projects on South Genesee Street.
    The victim’s brother, Mookie, initially was involved in
    the argument. A number of area residents were present
    and observed all or part of the events at issue and
    attempted to defuse the situation. Although the initial
    argument between the petitioner, the victim, and Moo-
    kie ended with the petitioner leaving the area in his
    car, he returned shortly afterward and the confrontation
    between him and the victim resumed. According to
    multiple eyewitnesses, the confrontation ended after a
    bystander to the argument fired a shot, at which point
    the petitioner drew a gun and fired it at the victim, who
    was standing only a few feet in front of him. The victim,
    who had attempted to duck or turn away from the
    petitioner just prior to the petitioner shooting, was
    struck by a bullet that entered his skull just above his
    right ear and exited the upper left side of his skull. The
    victim fell to the ground only after the petitioner fired
    his gun at the victim, and a forensic examination of
    the stippling around the wound demonstrated that the
    bullet that hit the victim had been fired from close
    range. The petitioner not only fled the immediate scene
    but also could not be located by law enforcement per-
    sonnel investigating the shooting because he left the
    state, which the state claimed evidenced his conscious-
    ness of guilt and supported its claim that he did not
    act in self-defense.
    The defense attacked the state’s case first by chal-
    lenging the credibility of the state’s witnesses and point-
    ing out the numerous factual inconsistencies in their
    testimony about the shooting, which the defense argued
    created reasonable doubt as to the trustworthiness of
    the evidence presented as a whole. The defense also
    argued that it was the victim, and not the petitioner,
    who had restarted the argument after initially walking
    away from the confrontation. Although not disputing
    that he had been armed or even that he had fired his
    gun, the petitioner asserted that he had fired only out
    of fear for his life in response to the first shot fired,
    which had hit the ground near his feet. The petitioner
    argued that events happened so fast that he never
    formed any specific intent to kill or cause serious physi-
    cal injury to anyone, including the victim. Further, he
    argued on the basis of the autopsy evidence regarding
    the trajectory of the bullet that struck the victim, cou-
    pled with the fact that no bullets or casings were ever
    recovered, that reasonable doubt clearly existed about
    whether his bullet had struck the victim rather than a
    bullet fired by someone else, perhaps even a ricochet
    from the first shot fired. Finally, he argued that he was
    not the initial aggressor and that he reasonably believed,
    on the basis of his observations, that the victim and
    others present were armed and that his own life was
    in danger at the time he fired his weapon and, accord-
    ingly, his actions were justified as self-defense.
    The state rebutted the petitioner’s claim of self-
    defense, arguing to the jury that the evidence presented
    at trial established beyond a reasonable doubt that the
    petitioner’s belief that he needed to use deadly physical
    force under the circumstances was objectively unrea-
    sonable. The state also asserted that it had established
    that the petitioner was the initial aggressor and that he
    had failed effectively to retreat from the conflict but,
    instead, having briefly left, had returned to continue
    the confrontation.
    C
    Our de novo consideration of whether Polan’s efforts
    to prepare and present the petitioner’s self-defense
    claim were objectively reasonable under the circum-
    stances necessitates that we begin with a more compre-
    hensive discussion of the evidence of self-defense that
    was before the jury at the criminal trial. Only after
    considering the evidence actually presented to the jury
    can we properly assess the significance of the evidence
    presented by the petitioner at the habeas trial and, in
    particular, the testimony provided by those habeas wit-
    nesses whom the petitioner offered in support of his
    allegations that Polan had not conducted a proper inves-
    tigation and improperly had failed to call as a trial
    witness at least one eyewitness to the shooting whom
    Polan knew of and had subpoenaed for trial.
    Roger B. Williams, Sr., was a key witness for the state
    at the petitioner’s criminal trial. Williams lived in the
    area of the shooting and knew both the victim and the
    petitioner. He testified that he was present throughout
    the relevant events and saw the petitioner shoot the
    victim. During the confrontation that took place shortly
    before the first shot was fired, Williams stated that the
    petitioner was standing only a few feet in front of the
    victim. According to Williams, Wright, Mookie, and oth-
    ers were all nearby during that initial confrontation
    between the petitioner and the victim. Mookie, how-
    ever, was no longer present when the argument contin-
    ued and the victim was shot. According to Williams,
    both the victim and Wright pulled out their guns before
    the petitioner. Next, a shot was fired, ostensibly by
    Wright,11 and the petitioner then pulled out a gun,
    pointed it at the victim, and fired. Williams testified
    that the victim, having seen the petitioner drawing his
    gun, ‘‘kinda threw his hands up and turned, turned away
    from him.’’ The victim did not fall to the ground until
    after the petitioner fired his weapon. Williams’ testi-
    mony, if credited by the jury, could have demonstrated
    that the victim and others nearby were armed at the
    time the victim was shot and that the victim had drawn
    a weapon before the petitioner fired a shot. This evi-
    dence, if credited, supported the petitioner’s claim that
    he feared that deadly force was about to be used against
    him and that he had fired only in self-defense. Williams’
    testimony also tended to show that the petitioner had
    not fired first, and thus that he may have done so in
    response to the initial shot fired.
    Kimberly Stevenson also was called by the state as
    a witness at the petitioner’s criminal trial. The victim
    and Stevenson had children together. She testified that
    she was looking out her bedroom window at the time
    of the shooting. She stated that she had spent the after-
    noon leading up to the shooting with the victim and
    that she never saw him with a gun during that time.
    She said that she only heard the first gunshot and did
    not see who fired it. She claimed that, after hearing
    that first shot, however, she saw the petitioner pull a
    revolver from his pants and fire at the victim’s head.
    On cross-examination, Stevenson, like Williams, testi-
    fied that Mookie was not present at the time the shoot-
    ing occurred. She also denied that she had told O’Don-
    nell prior to trial that she had seen Wright with a gun
    in his hand at the time the first shot was fired. Similar
    to Williams, Stevenson indicated that the victim was
    turning away from the petitioner when he was shot.
    Although Stevenson’s testimony was damaging to the
    petitioner in some ways, she testified consistently with
    other witnesses that a shot was fired before the peti-
    tioner shot the victim, thereby lending some support
    to the defense claim that the petitioner feared for his
    life and fired in response to a perceived threat.
    Andre Martin, who was a friend of the petitioner and
    an eyewitness to the shooting, was called to testify at
    the criminal trial by the state but indicated on the stand
    that he had no memory of what had transpired at the
    time of the shooting. Pursuant to § 6-10 of the Connecti-
    cut Code of Evidence and State v. Whelan, 
    200 Conn. 743
    , 
    513 A.2d 86
    , cert. denied, 
    479 U.S. 994
    , 
    107 S. Ct. 597
    , 
    93 L. Ed. 2d 598
     (1986), the criminal trial court
    admitted into evidence for substantive purposes a tran-
    script of a recorded oral statement given by Martin to
    the police.12 In that statement, Martin indicated that he
    saw the petitioner draw a gun, point it at the victim, and
    then fire one shot. Martin’s testimony was particularly
    damaging to the defense, but Polan, through her cross-
    examination of Martin, attempted to discredit the verac-
    ity of Martin’s statement to the police by drawing the
    jury’s attention to the fact that the statement was given
    while Martin was in custody on charges unrelated to
    the present case and facing a charge of violation of pro-
    bation.
    Two officers who responded to the scene shortly
    after the shooting, Matthew Myers and Willie Ponteau,
    each testified at trial on behalf of the state. Ponteau,
    who lived near the crime scene and was home at the
    time of the shooting, heard two gunshots fired in close
    succession to one another, which were then followed
    by multiple shots. Although Ponteau had no way of
    knowing who fired the shots that he heard, his testi-
    mony regarding the number of shots and their timing
    relative to one another was not inconsistent with the
    testimony of other witnesses who indicated that the
    petitioner had fired immediately after the initial shot.
    Both officers testified that they did not observe any
    type of weapon on or near the victim. Ponteau, however,
    remembered seeing Stevenson near the body when he
    arrived and, on cross-examination by Polan, Ponteau
    admitted that he had no knowledge of whether someone
    may have removed a gun from the victim before the
    police arrived. This testimony did not undermine other
    evidence that the victim had been armed, which lent
    support to the defense argument that the petitioner
    reasonably feared that he was in danger of having
    deadly force used against him when he shot the victim.
    The petitioner testified on his own behalf in support
    of his claim of self-defense. According to the petitioner,
    before the first gunshot was fired, he was standing
    about five feet away from, and directly in front of, the
    victim. The petitioner did not know whether the victim
    actually had a gun but had observed him fumbling with
    his pocket in a way that suggested he might be armed.
    The petitioner also indicated that he believed Mookie
    had a gun based on ‘‘the way he was acting.’’ The peti-
    tioner testified that he pulled out his handgun only in
    response to the first gunshot and fired it in the direction
    of the victim because he believed that that was the
    direction from which the first shot had been fired.
    According to the petitioner, the victim was still standing
    after the petitioner fired and started running away from
    the scene.
    The state, through its cross-examination of the peti-
    tioner, was able to undermine the petitioner’s direct
    testimony. Specifically with respect to his self-defense
    claim, the state was able to undermine the petitioner’s
    assertion that he was in fear when he fired at the victim,
    getting him to admit that he was familiar with guns, he
    often carried one, he had heard gunshots fired near him
    in the past and, in fact, he ‘‘had been shot at before.’’
    The petitioner also testified on cross-examination that,
    on the day of the shooting, he was not always sure
    when he was in actual possession of his gun, indicating
    that sometimes he left it in the glove compartment of his
    vehicle. Although the petitioner never disputed having
    a weapon or firing it toward the victim, the jury reason-
    ably could have inferred from his testimony that he
    may not have had his gun when the argument with the
    victim first begun and that he left the argument initially
    only to return to his car and retrieve his gun, facts
    relevant both to the duty to retreat and to whether the
    petitioner was the initial aggressor. Finally, the jury
    was provided with testimony from Susan Williams, the
    medical examiner who performed the autopsy of the
    victim. She provided testimony that the victim had a
    one-quarter inch entrance wound on the right side of
    his head, approximately two inches above and behind
    his right ear, and an approximately three inch exit
    wound on the left side of his forehead. She described
    the path of the bullet that made the wounds as travelling
    ‘‘leftward, forward, and slightly upward.’’ She further
    explained that stippling around the entrance wound,
    which is caused when gunpowder expelled along with
    the bullet abrades the skin, indicated that the gun from
    which the bullet had come was fired within approxi-
    mately two feet of the victim. The evidence concerning
    the trajectory and location of the bullet wound provided
    a basis for Polan to suggest to the jury that reasonable
    doubt existed concerning the source of the bullet that
    killed the victim. Specifically, it tended to support an
    argument that the bullet could not have come from the
    petitioner’s weapon because he was standing directly
    in front of the victim when he fired, rather than to the
    victim’s right. It was also consistent with the defense
    theory that it was the result of a ricochet from the first
    shot fired because the bullet entered the right side of
    the victim’s skull travelling upward. Of course, both
    arguments failed to account for the testimony that the
    victim had been turning away from the petitioner when
    the petitioner fired or for the presence of the stippling,
    which tended to show that the wound had been caused
    by a bullet fired directly from a weapon at close range.
    Polan, attempting to capitalize on the inconsistent
    factual testimony of the state’s own witnesses, began
    her closing argument by attempting to persuade the
    jury that there was reasonable doubt about what had
    occurred, including as to whether the state had proven
    that the petitioner intended to kill the victim when he
    fired his weapon or whether it was the petitioner’s bullet
    that killed the victim. Polan later also advanced the
    argument that, even if the petitioner’s bullet had hit
    the victim, the petitioner had fired his weapon in self-
    defense. Polan emphasized to the jury that as long as
    the petitioner had presented some evidence that would
    support his claim of self-defense, the burden shifted to
    the state to disprove self-defense beyond a reasonable
    doubt, which Polan argued the state had failed to do.
    She highlighted the petitioner’s testimony that he
    believed he was in imminent danger of being shot, and,
    in fact, that he initially thought that he had been shot.
    She also noted that the state could not demonstrate
    that the petitioner’s belief was objectively unreasonable
    because all of the state’s witnesses had testified that
    someone else had fired a shot before the petitioner
    discharged his weapon.
    Polan also highlighted Williams’ testimony that the
    first shot hit the dirt near the petitioner’s feet. Polan
    argued to the jury that the state could not prove that
    the petitioner had used unreasonable force under the
    circumstances when he fired his gun, stating that it was
    undisputed that the petitioner was being shot at, the
    petitioner ‘‘had his back against the wall, there was no
    way he could get out, and he used deadly force because
    deadly force was being used against him.’’ She argued
    that although the state could defeat the petitioner’s self-
    defense claim if it could prove that the petitioner had
    been the initial aggressor, the evidence did not support
    such a finding beyond a reasonable doubt. She stated:
    ‘‘There is no evidence in this case that [the petitioner]
    drew his weapon or made any movement [as] if he was
    going to draw a weapon before either [the victim] was
    reaching for his pocket as [Williams] says or a shot was
    fired at [the petitioner’s] feet, that’s the reality.’’
    Polan ended her closing argument by summarizing
    her theory of the defense, stating: ‘‘This is a tragic kill-
    ing, it’s a tragedy that [the victim] is . . . not with us
    today but it’s not a murder. It’s not a murder because
    the state cannot prove the specific intent to kill beyond
    a reasonable doubt and again there is ample evidence
    here that [the petitioner] acted in self-defense. He was
    shot at [and] didn’t know where the shots were coming
    from. It all happened so quickly that he did not form
    a specific intent to kill [the victim]. Yes, he shot in
    his direction he told you that when he testified here
    yesterday but his intent was not to kill [the victim].
    [His] intent was to protect himself.’’ After the state’s
    rebuttal argument, the court instructed the jury on the
    law, which included a detailed and lengthy instruction
    on self-defense. See footnote 10 of this opinion. Ulti-
    mately, the jury acquitted the petitioner of the murder
    charge, but found him guilty of the lesser included
    offense of manslaughter in the first degree with a fire-
    arm, rejecting the petitioner’s self-defense argument.
    By way of summary, and as this court indicated in
    deciding the petitioner’s direct criminal appeal, the trial
    witnesses gave partially conflicting or inconsistent
    accounts of the shooting. Their testimony differed as
    to who was present when the victim was shot, where
    people were standing with respect to one another, and
    who was carrying a weapon. Although the state’s case
    against the petitioner was strong, consisting of more
    than one eyewitness who observed the petitioner shoot
    the victim in the head at close range, sufficient evidence
    nonetheless was introduced to the jury through those
    same witnesses that, if credited by the jury, could have
    supported the petitioner’s claim that he nonetheless
    had acted in self-defense. The jury ultimately concluded
    in convicting the petitioner of manslaughter in the first
    degree with a firearm that the state had disproven self-
    defense beyond a reasonable doubt. Nevertheless, our
    review of the criminal trial transcripts does not reflect
    any evidence from which reasonably to conclude that
    Polan either lacked adequate preparation for trial or
    was not knowledgeable about the facts of the case. In
    fact, Polan made effective use of the available evidence
    in her closing argument to the jury.
    D
    Turning to the habeas proceedings, the habeas court
    nevertheless concluded that Polan had provided inef-
    fective assistance with respect to the petitioner’s claim
    of self-defense. The habeas court based that conclusion
    principally on two reasons. First, the habeas court con-
    cluded that Polan had not conducted an adequate pre-
    trial investigation, which, according to the court,
    resulted in her having failed to discover several addi-
    tional witnesses that the habeas court concluded would
    have helped her raise reasonable doubt regarding self-
    defense. In reaching that conclusion, the habeas court
    appears to have relied exclusively on the testimony of
    the witnesses offered by the petitioner at the habeas
    trial, whom the habeas court found to be credible. The
    court specifically attributed Polan’s failure to call the
    witnesses whom the petitioner presented at the habeas
    trial to ‘‘Polan’s deficient investigation.’’ Second, the
    habeas court concluded that Polan acted deficiently by
    not calling Jones to testify at the criminal trial, although
    Polan allegedly knew of Jones and had subpoenaed her
    as a witness for trial.
    The respondent, however, contends that the habeas
    court’s findings regarding the investigation were clearly
    erroneous because they were unsupported by any evi-
    dence in the record and, in fact, suggests that the record
    directly contradicts the court’s findings. The respon-
    dent also maintains that, although the court found the
    habeas witnesses credible, it failed to consider (1)
    whether Polan may have had an objectively reasonable
    strategic reason for not seeking out additional wit-
    nesses beyond those already identified by the state or
    through the efforts of her investigator or (2) whether
    knowledge of the habeas witnesses’ testimony would
    have caused a reasonably competent defense counsel
    to have altered the defense strategy pursued at trial.
    We find the respondent’s arguments persuasive, partly
    because the habeas court’s conclusions are not sup-
    ported by relevant and necessary factual findings
    regarding Polan’s investigative efforts and partly
    because of the lack of any apparent consideration by
    the court of whether a sound strategic reason might
    have existed for Polan’s decisions regarding various
    witnesses. Furthermore, the court’s conclusions are
    legally and logically flawed because they impermissibly
    shift the evidentiary burden of persuasion away from
    the petitioner and to the respondent.
    The flaws in the habeas court’s conclusions are appar-
    ent from our review of the habeas trial transcripts. More
    specifically, they are apparent from the testimony of
    the witnesses on which the court relied in concluding
    (1) that Polan had failed to conduct a sufficient investi-
    gation of the shooting, and (2) that a proper investiga-
    tion would have uncovered witnesses whose testimony
    would have bolstered in some significant way the peti-
    tioner’s claim of self-defense. In considering that testi-
    mony, we focus our attention on what evidence the
    petitioner produced that directly pertained to Polan’s
    investigative efforts, her knowledge or lack of knowl-
    edge of each particular witness, and, with respect to
    witnesses who were known or likely known to Polan,
    whether she may have had a reasonable strategic reason
    for not calling them to testify at the criminal trial.
    ‘‘Although it is incumbent on a trial counsel to conduct a
    prompt investigation of the case and explore all avenues
    leading to facts relevant to the merits of the case and
    the penalty in the event of conviction . . . counsel
    need not track down each and every lead or personally
    investigate every evidentiary possibility. . . . In a
    habeas corpus proceeding, the petitioner’s burden of
    proving that a fundamental unfairness had been done
    is not met by speculation . . . but by demonstrable
    realities.’’ (Internal quotation marks omitted.) Johnson

    The petitioner first called O’Donnell, Polan’s investi-
    gator, to testify at the habeas trial. O’Donnell had very
    limited memory of his work in this matter. O’Donnell’s
    testimony generally was unhelpful in establishing the
    petitioner’s habeas claims because O’Donnell was
    unable to provide any insight into the extent of Polan’s
    efforts to investigate or to locate witnesses in this case,
    or to describe the fruits of any discussions that Polan
    had with the petitioner. Rather, O’Donnell’s testimony
    tended to show that, at a minimum, Polan had taken
    the reasonable step of hiring an investigator to look
    into aspects of the case. Ultimately, although O’Donnell
    had sat with Polan at counsel table throughout the trial,
    his testimony was devoid of any insight into Polan’s
    decision–making process in this case or her defense
    strategy. O’Donnell specifically indicated that he ‘‘never
    discussed the witness list with [Polan].’’ Certainly, noth-
    ing in his testimony aided the petitioner in proving his
    habeas claims.
    2
    Next, the petitioner presented testimony from three
    witnesses—Audrey Jordan, Alexis Jordan, and Jymisha
    Freeman—all of whom were closely related to each
    other and to the victim, and none of whom actually
    witnessed the shooting at issue. Because these three
    witnesses provided roughly the same factual testimony
    relative to the issue of self-defense, we address them
    together. It is important to stress at the outset that the
    habeas court made no subsidiary findings regarding
    whether Polan or O’Donnell knew of these witnesses,
    had spoken to them about the incident, the content of
    any conversation the defense may have had with the
    witnesses, or whether the witnesses’ versions of events
    at that time differed from the version of facts to which
    they testified at the habeas trial. It was important for
    the petitioner to present these facts, particularly in light
    of Polan’s unavailability, in order to overcome the pre-
    sumption of constitutionally adequate performance.
    Audrey is Alexis’ mother and the sister of the peti-
    tioner and Jymisha. She testified at the habeas trial that
    she did not see the shooting, but only heard the gunfire
    from where she had been lying down inside her mother’s
    house. She stated that when she arrived at the scene
    of the shooting, she saw Stevenson kneeling over the
    victim’s body and placed her hand on Stevenson’s back.
    Audrey indicated that an unidentified person whispered
    something into Stevenson’s ear, after which Stevenson
    went inside her house and brought back a white cloth.
    Stevenson used that cloth to pick up and wrap a gun that
    was lying within inches of the victim’s body. Stevenson
    took the gun inside the house, then returned to her
    position beside the victim’s body. Audrey indicated that
    she saw Williams at the scene but did not see Jones,
    who, as we will discuss later, also testified at the habeas
    trial as an eyewitness to the shooting. Audrey observed
    several bullet holes in the petitioner’s car, which was
    still at the scene.
    Alexis testified at the habeas trial that the petitioner
    was her uncle. She was eight years old at the time of
    the shooting, and testified that she did not witness the
    victim being shot. She only heard the gunshots, approxi-
    mately ten in total, from where she was inside her
    grandmother’s home. She stated that when she ran out-
    side, she saw the victim lying on the ground and a gun
    lying a few inches from his body. She testified that she
    then saw Stevenson go inside the house and retrieve a
    cloth of some sort, which Stevenson used to wrap up
    the gun and remove it from the scene.
    Jymisha Freeman is the petitioner’s sister and Alexis’
    aunt. She was only ten or eleven years old at the time
    of the shooting, and testified at the habeas trial that
    she was with Alexis inside her mother’s house when
    she heard more than ten gunshots. She followed Alexis
    outside after the gunfire stopped. She was standing
    farther back from the body than Alexis and never saw
    a gun herself. She testified, when asked on cross-exami-
    nation, that she saw Stevenson exit her house with a
    towel or cloth, although she did not observe her do
    anything with it.
    With respect to Polan’s investigative efforts and her
    knowledge of these witnesses in particular, it cannot
    reasonably be inferred from the testimony of these three
    witnesses that Polan failed to conduct a proper investi-
    gation or that she was unaware of what they could have
    told a jury if they had been called to testify at the
    criminal trial. Audrey testified that although she did not
    go to the police with her story, she eventually was
    interviewed by Detective Willoughby, who took notes
    of what she told him. She testified inconsistently about
    whether she also had provided a written statement.
    Importantly, she indicated that she spoke with both
    Polan and O’Donnell about what had happened on the
    day of the shooting, and that she was subpoenaed for
    trial but later was told that her testimony would not
    be needed. The petitioner never asked Audrey to testify
    about what she had told Polan or O’Donnell regarding
    the shooting. Alexis testified that she never had spoken
    with the police or any investigator about the incident,
    and could not recall if she ever had spoken to Polan.
    Similarly, Jymisha testified that she never spoke to the
    police and never spoke to Polan about the shooting.
    Audrey may have told Polan and O’Donnell not only
    about the details of the shooting but about Alexis’ and
    Jymisha’s presence that day and what they may have
    observed.
    The petitioner, in his habeas trial testimony, also
    indicated that he had told Polan that he had seen Jymi-
    sha outside, so Polan also may have had this informa-
    tion when she spoke with Audrey. We do not know
    from this record whether these three witnesses’ names
    also appeared in police reports, none of which were
    made part of the habeas record, or if they were men-
    tioned to Polan or O’Donnell by prosecutors or other
    eyewitnesses. In light of the strong, albeit rebuttable,
    presumption that trial counsel’s investigative efforts fall
    within the necessarily wide range of constitutionally
    adequate performance, it is unreasonable to infer that
    Polan was unaware of these witnesses given the lack
    of evidence on this question.
    Moreover, with respect to the petitioner’s self-
    defense claim, these witnesses’ testimony did not fill
    or implicate any critical or missing evidentiary element
    of self-defense. Their testimony, both independently
    and by way of corroboration of each other’s testimony,
    only tended to demonstrate that a gun had been lying
    on the ground very near to the victim’s body after he
    was shot, suggesting that it was the victim’s gun and
    that he may have had it when he was shot. Williams,
    however, who testified on behalf of the state at the
    criminal trial and on whose testimony the state relied
    in support of its case, testified before the jury that the
    victim had drawn a gun prior to being shot by the
    petitioner. The habeas testimony regarding the pres-
    ence of a gun after the fact was cumulative of, and not
    as compelling as, Williams’ testimony, and certainly
    could not be considered essential to the defense.
    Furthermore, whether the state successfully could
    disprove self-defense in this case did not depend on a
    determination of whether the victim actually had been
    armed, but only on the state disproving beyond a rea-
    sonable doubt that the petitioner had both a subjective
    and an objectively reasonable belief that the victim, or
    someone supporting the victim, was armed and about
    to use deadly force against the petitioner. Given Alexis’
    and Jymisha’s young ages at the time of the shooting and
    the fact that the petitioner was a close family member
    to them and to Audrey, if Polan knew of their potential
    testimony, a fact that cannot be determined on this
    record, Polan reasonably may have made the strategic
    decision not to call them. After all, the state’s own
    witnesses tended to establish at the criminal trial that
    persons other than the petitioner were armed, had
    drawn weapons, and had fired once prior to the peti-
    tioner firing his own gun. Although Polan’s strategy with
    respect to self-defense ultimately proved unsuccessful,
    that certainly did not render her strategic choices per
    se unreasonable.
    3
    We turn next to the habeas trial testimony provided
    by Jones. She testified at the habeas trial that she was
    a friend not only of the petitioner and his family, but
    also was friendly with the victim. She claimed that she
    was one of many persons present during the argument
    that preceded the victim being shot. According to Jones,
    during the argument with the victim, the petitioner
    stood only two or three feet in front of the victim. She
    testified that the victim’s brother, Mookie, was standing
    close behind the victim at the time and that he too was
    involved in the argument. Jones testified that she never
    saw the petitioner leave and come back. Jones indicated
    that, as the argument got more and more heated, the
    victim reached multiple times for a gun that was tucked
    into his waistband, although she stated that he never
    drew it. Although Jones at first asserted that she saw
    Mookie fire the first shot, in subsequent testimony she
    indicated that she inferred it was Mookie who fired the
    first shot because she had observed dust or smoke
    coming from the gun he was holding immediately after
    the first shot was fired. According to Jones, it was not
    the first shot that killed the victim but a second shot
    that she claimed was fired by someone she did not see.
    Jones claimed that when the victim fell to the ground,
    his gun fell out of his waistband. Although she testified
    that she ran into the building where her sister lived
    shortly after the shots were fired, she also testified that
    she had observed Stevenson remove the gun from the
    scene and wrap it in a white towel.
    It is undisputed that Polan was aware of Jones and
    had taken her statement about the events and, there-
    fore, any decision not to call Jones at trial cannot be
    attributed to a failure by Polan to investigate the shoot-
    ing. Jones testified that she spoke with the police about
    the incident and gave them a statement. She also testi-
    fied that she had met with O’Donnell several times prior
    to the criminal trial and had provided him with a state-
    ment. She claims that she was subpoenaed for trial by
    the defense but that ultimately she was told that her
    testimony would not be needed. The record is silent
    regarding the reason for Polan’s decision. Notably, how-
    ever, the pretrial statement that Jones provided to
    O’Donnell, which was admitted as an exhibit during the
    habeas trial, differed in some ways from the testimony
    that Jones provided at the habeas trial.
    In her written statement, Jones claimed that she had
    observed the initial confrontation between the peti-
    tioner, the victim, and Mookie. After that initial argu-
    ment ended, but before the petitioner left in his car,
    she heard the petitioner ask the victim, ‘‘you going to
    confront me with a gun?’’ Jones then observed the peti-
    tioner leave in his car but return about five minutes
    later and resume his argument with the victim and Moo-
    kie. She stated that Mookie pulled a gun from his waist-
    band and fired a shot, at which time both the victim
    and the petitioner pulled out guns. Finally, she stated
    in her written statement that the victim did not fall to
    the ground until after the petitioner fired his gun.
    Whether to call a particular witness at trial, however,
    is a tactical decision for defense counsel, and, to the
    extent that the decision ‘‘might be considered sound
    trial strategy,’’ it cannot be the basis of a finding of
    deficient performance. See Strickland v. Washington,
    
    supra,
     
    466 U.S. 689
    . Polan’s strategic decision not to
    call Jones as a witness at the criminal trial can properly
    be evaluated only on the basis of what Polan knew
    about Jones’ potential testimony at the time of trial,
    not on the basis of the testimony that Jones later gave
    at the habeas trial, regardless of whether the habeas
    court deemed her later testimony credible. Jones’ writ-
    ten statement, like her testimony at the habeas trial,
    indicated that she had information that was relevant
    to the petitioner’s claim of self-defense.13 There are a
    number of plausible reasons, however, why Polan may
    have decided that calling Jones to testify was either
    unnecessary or inadvisable because, even if she was
    believed by the jury, calling her might have opened up
    avenues of inquiry that would have hurt the defense’s
    case.
    First, Jones had a criminal record and was a friend
    of the petitioner and, therefore, her testimony would
    have been subject to significant impeachment by the
    state. Jones’ account of the shooting contradicted that
    of other witnesses and the petitioner’s own criminal
    trial testimony. For example, Jones claimed that Mookie
    was standing close to the victim both during the initial
    argument and at the time of the shooting, whereas Wil-
    liams had testified at the criminal trial that Mookie was
    not present and the petitioner had testified that Mookie
    was ‘‘[s]tanding like off in the shadows.’’ Further, and
    perhaps most importantly, the statement given by Jones
    to O’Donnell clearly indicated that she had heard the
    petitioner comment that he was aware that the victim
    was armed shortly before he drove off, returning a short
    time later. If Jones had stuck to that story at the criminal
    trial, as Polan might reasonably have expected, it could
    have undermined the petitioner’s claim of self-defense
    by suggesting that he had left the scene in order to
    arm himself. In sum, after hearing the state’s witnesses,
    Polan may have decided that Jones’ testimony was not
    critical to her client’s self-defense claim and that the
    better strategic choice was to not call her as a witness.
    That is precisely the type of trial strategy that Strickland
    prohibits us from second-guessing postconviction.
    4
    Walker, who was a close friend of the victim, also
    testified at the habeas trial. He testified that he had
    witnessed the confrontation between the petitioner and
    the victim, claiming that he had stood about four feet
    from the victim during the argument leading up to the
    shooting. He testified that he saw the victim ‘‘flashing’’
    a gun, but claimed that the gun stayed in the victim’s
    waistband and that he never saw the victim ‘‘pull it
    out.’’ Walker testified that he did not see who fired the
    first few shots because he was turned away but, when
    he looked back, he saw the victim on the ground. He
    also testified that he observed Mookie firing his weapon
    from where he had been standing on a stairway about
    ten or fifteen feet behind the victim. Walker further
    testified that he saw someone remove a weapon in a
    towel. When pressed, however, he said it was Williams
    who had done so, not Stevenson, as others had testified.
    Walker remembered seeing both Jones and Williams at
    the scene of the shooting.
    Walker spoke with the police after the shooting but
    testified that he had never spoken to Polan or O’Don-
    nell. He was not asked about the substance of his discus-
    sion with the police, however, and the habeas record
    contains no additional details about what he saw or
    said. Even so, according to the petitioner’s testimony,
    he had discussed Walker with Polan. Further, as noted
    with other witnesses, the fact that Walker testified that
    he never spoke with any member of the defense team
    directly does not mean that Polan had not learned about
    Walker or his account of the shooting by reviewing
    police reports, interviewing the police, or discussing
    the case with prosecutors. Walker’s testimony that the
    victim never actually drew his weapon was less compel-
    ling for purposes of the petitioner’s self-defense claim
    than the testimony of Williams, who claimed that the
    victim actually drew his weapon. Given that his testi-
    mony also conflicted factually in other respects with
    that of other witnesses, even if Polan was aware of
    his account, she reasonably might have chosen not to
    present his testimony, believing that she would have a
    better chance of persuading the jury by relying on the
    state’s witnesses.
    5
    The final eyewitness to the relevant events presented
    by the petitioner at the habeas trial was Wright, the
    person who Williams testified at the criminal trial was
    present at the time of the shooting and was likely the
    person who had fired the first shot. Wright did not
    testify at the criminal trial. Wright testified at the habeas
    trial that he was friendly with both the victim and the
    victim’s brother, Mookie. Wright stated that he was in
    the vicinity of the shooting when it occurred. Wright
    claimed that he saw the victim pull a gun from his
    waistband, at which point he decided to leave the scene.
    As he was leaving, however, he heard shots being fired.
    He denied that he personally had a gun at the time or
    that he was responsible for any gunshots that were
    fired either before or after the victim was shot.
    As with Walker, there was no evidence presented to
    the habeas court that would have permitted the court
    to find, in contravention of the strong presumption of
    reasonable competence, that Polan or her investigator
    was either unaware of Wright’s account or that Polan
    had failed to investigate him as a potential witness. See
    Thompson v. Commissioner of Correction, supra, 
    131 Conn. App. 698
     (presumption of competent representa-
    tion includes presumption of adequate investigation).
    Wright testified that he spoke with the police and also
    with an investigator from the prosecutor’s office. His
    name was also provided to Polan by the petitioner.
    Assuming that the version of events provided by Wright
    at the habeas trial was known to Polan, as were the
    accounts of the other habeas witnesses, his testimony
    did not add in any significant way to the theory of self-
    defense actually pursued by Polan at trial nor did his
    testimony advance any alternative theory of defense
    that she could have pursued. Furthermore, it is reason-
    able to assume that Polan did not think that Wright
    would provide credible testimony because he had been
    identified by Williams as someone who was armed and
    may have fired the first shot.
    6
    The petitioner also testified on his own behalf at the
    habeas trial, as he had at the criminal trial. With respect
    to Polan’s investigative efforts, the petitioner stated
    only that he had given Polan the names of several wit-
    nesses, including Freeman, Jones and Walker. Polan
    had told the petitioner that Jones had given the defense
    a written statement and that she believed this was a
    self-defense case. The petitioner testified that he
    believed that his self-defense strategy would have
    included calling a number of additional witnesses. The
    petitioner, however, provided no testimony that ade-
    quately filled in the evidentiary gaps created by Polan’s
    unavailability at the habeas trial, including details about
    her efforts in reviewing the case file, the discovery
    provided by the state, her conversations with witnesses,
    and what she may have learned through the efforts of
    O’Donnell and others. The petitioner likewise provided
    no insight regarding Polan’s strategy at trial.
    7
    Finally, the petitioner presented expert testimony
    from McKay. Although McKay had no direct knowledge
    of Polan’s investigation, he nonetheless opined, on the
    basis of the habeas witnesses’ testimony that was not
    presented at the criminal trial, that Polan ‘‘should have
    put more effort’’ into presenting the petitioner’s self-
    defense claim to the jury. He testified that if Polan had
    presented the testimony of witnesses to establish that
    the victim had a gun, this would have strengthened
    the self-defense claim of the petitioner. Nevertheless,
    because the petitioner himself never claimed that he
    saw a gun, meaning the actual presence of a gun was
    not relevant to his subjective/objective perception of
    danger, whether other people had seen a gun or a gun
    actually was present would not have aided his claim of
    self-defense. Although he questioned the soundness of
    having O’Donnell sit at counsel table throughout the
    trial, which resulted in Polan’s inability to call him as an
    impeachment witness, McKay’s opinions about Polan’s
    investigation amounted to little more than speculation.
    McKay admitted on cross-examination that he was
    unaware of the actual availability of the witnesses who
    testified at the habeas trial, how their stories may have
    differed from their accounts at the time of trial, or ‘‘what
    kind of baggage’’ those witnesses may have had that
    would have weighed against calling them as witnesses
    at the criminal trial.
    E
    Turning to our consideration of the totality of evi-
    dence presented at the habeas trial regarding Polan’s
    investigative efforts to discover witnesses necessary to
    support the petitioner’s assertion that he acted in self-
    defense, we cannot agree on the basis of our plenary
    review of the record that the petitioner met his burden
    of demonstrating that Polan’s investigation in this case
    or her decision not to call Jones or other available
    witnesses known to her necessarily constituted defi-
    cient performance. Our review of the habeas court’s
    memorandum reveals that the habeas court made its
    finding of an inadequate investigation without reference
    to or analysis of the facts regarding the investigative
    efforts actually taken or not taken by Polan or her
    investigator. In fact, the habeas court does not discuss
    those efforts and makes no relevant subordinate find-
    ings. Rather, it appears that the habeas court reached
    its conclusion of ineffective assistance largely on the
    basis of its finding that the ‘‘witnesses who testified at
    the habeas trial were credible, both individually and
    collectively.’’ The court concluded on the basis of this
    credibility determination that it lacked ‘‘confidence in
    the outcome of the jury trial.’’
    In so concluding, however, the habeas court appears
    to have addressed the prejudice prong without having
    first made a determination that counsel’s representation
    was deficient. Indeed, the habeas court’s finding that
    the testimony of the habeas witnesses was credible and
    that these witnesses could have lent additional support
    to the petitioner’s claim of self-defense, puts the cart
    before the horse and does not squarely address the
    issue of deficient performance, i.e., whether Polan’s
    failure to call these credible witnesses was fairly attrib-
    utable to a constitutionally deficient investigation or
    whether, if aware of a particular witness, she lacked
    any reasonable strategic reason for proceeding in the
    manner that she did. Instead, the conclusion that these
    witnesses would have been helpful to the petitioner’s
    self-defense claim pertains, more directly, to prejudice.
    Although a habeas court certainly may reject a claim
    of ineffective assistance by addressing whichever prong
    of the analysis is easier, in order to conclude that a
    habeas petitioner has succeeded with respect to such
    a claim, it must engage in an independent consideration
    of both prongs, each of which must be satisfied indepen-
    dently. See Breton v. Commissioner of Correction, 
    325 Conn. 640
    , 669, 
    159 A.3d 1112
     (2017); see also Skakel
    v. Commissioner of Correction, 
    329 Conn. 1
    , 5, 
    188 A.3d 1
     (2018) (to establish ineffective assistance, petitioner
    must establish both that counsel’s failure to secure evi-
    dence was ‘‘constitutionally inexcusable’’ and that
    proven deficiency ‘‘undermines confidence in the relia-
    bility of the petitioner’s conviction’’), cert. denied,
    U.S. , 
    139 S. Ct. 788
    , 
    202 L. Ed. 2d 569
     (2019). Here,
    the habeas court appears to have employed the type
    of ‘‘hindsight’’ and after-the-verdict second-guessing of
    counsel that Strickland expressly warns against. See
    Strickland v. Washington, 
    supra,
     
    466 U.S. 689
    .
    Although ‘‘trial counsel’s testimony is not necessary
    to [a] determination that a particular decision might be
    considered sound trial strategy’’; Bullock v. Whitley, 
    53 F.3d 697
    , 701 (5th Cir. 1995); ‘‘[a] habeas petitioner’s
    failure to present trial counsel’s testimony as to the
    strategy employed at a petitioner’s criminal trial ham-
    pers both the court at the habeas trial and the reviewing
    court in their assessments of a trial strategy.’’ Franko
    v. Commissioner of Correction, 
    165 Conn. App. 505
    ,
    519, 
    139 A.3d 798
     (2016). In such circumstances, a
    habeas court ‘‘must examine all other available evi-
    dence from the trial record in order to determine
    whether the conduct complained of might be consid-
    ered sound trial strategy.’’ (Emphasis added.) 
    Id.
    As indicated by the United States Court of Appeals
    for the Fifth Circuit in Bullock, it is not necessary for
    a reviewing court to resolve what strategic decisions
    defense counsel actually made, but it is ‘‘required to
    presume that the challenged actions were within the
    wide range of reasonable professional conduct if, under
    the circumstances, it might have been sound trial strat-
    egy.’’ (Emphasis added; internal quotation marks omit-
    ted.) Bullock v. Whitley, 
    supra,
     
    53 F.3d 701
    . The peti-
    tioner has the burden to overcome that presumption
    of reasonable professional conduct; id.; and Polan’s
    death did not relieve the petitioner of the substantial
    burden of demonstrating that Polan’s representation
    was less than constitutionally competent. See Slevin v.
    United States, 
    supra,
     
    71 F. Supp. 2d 358
     n.9.
    Therefore, as the respondent correctly argues, it was
    the petitioner’s burden to show that Polan did not
    attempt to investigate various witnesses’ accounts of
    the shooting. Polan was not available to testify about
    the investigation, and the petitioner was unable to elicit
    any relevant details from Polan’s investigator, O’Don-
    nell, about the efforts Polan or he took to locate and
    interview witnesses. Although it may be true that O’Don-
    nell’s testimony was of minimal utility because he
    asserted that he had virtually no memory of the investi-
    gation, this did not shift the burden to the respondent
    to prove an adequate investigation. In the absence of
    any evidence to overcome the strong presumption that
    Polan had engaged in an objectively reasonable investi-
    gation, it was improper for the habeas court to have
    speculated that the witnesses who testified at the
    habeas trial were not known to Polan14 or that she had
    elected not to call them on the basis of anything other
    than a reasonable strategic choice.
    Furthermore, because counsel is presumed to have
    acted reasonably in the absence of evidence to the
    contrary, without any evidence of Polan’s trial strategy,
    the habeas court was required to consider whether
    there was any plausible reason for not calling the vari-
    ous witnesses. The habeas court’s memorandum is
    silent with respect to possible rationales for limiting
    the investigation or not calling certain witnesses.
    Rather, the habeas court observed that it had ‘‘no
    evidence directly from Polan about any of her trial
    strategies and the tactical decisions she made to accom-
    plish them.’’ This would include her investigative strat-
    egy. The petitioner had the burden of establishing that
    Polan’s investigation fell outside the wide range of pro-
    fessional conduct considered reasonable, but such evi-
    dence is lacking here. Judging the reasonableness of
    investigative efforts ‘‘depends critically’’ on the informa-
    tion that counsel receives from her client. See Gaines
    v. Commissioner of Correction, supra, 
    306 Conn. 681
    .
    Here, the petitioner testified at the habeas trial that he
    had made Polan aware of several witnesses, including
    Jymisha, Wright, Walker, and Jones. His testimony,
    however, offered no insight as to whom Polan or O’Don-
    nell actually had interviewed, whether the defense team
    had knowledge of witnesses’ potential testimony from
    their review of police records or discussions with the
    prosecutors or other witnesses, or whether Polan
    decided that she effectively had gathered the factual
    basis for the defenses she sought to pursue through the
    testimony of the state’s trial witnesses.
    Polan indisputably pursued a self-defense claim at
    trial in the present case. The petitioner concedes that
    Polan properly requested and received a jury instruction
    on self-defense, and a review of the trial transcript
    shows that she spent a portion of her closing argument
    attempting to persuade the jury that the petitioner had
    fired his weapon in self-defense. Furthermore, the self-
    defense case that Polan presented at the criminal trial
    was not markedly different than the one the petitioner
    advanced at the habeas trial. Polan was able to argue
    on the basis of the evidence presented at the criminal
    trial, largely through the state’s own witnesses, that the
    petitioner fired his weapon toward the victim, whom
    he had reason to believe was armed, only after hearing
    a gunshot fired by an unknown person. The only addi-
    tional information pertaining to self-defense that a jury
    could have gleaned from the habeas trial witnesses’
    testimony that was not presented at the criminal trial
    was that it was highly likely that the victim had, in fact,
    been armed at the time he was shot, because multiple
    witnesses either saw him with a gun before he was shot
    or saw someone remove a gun from near his body after
    he was shot. As the respondent persuasively argues,
    however, these additional facts, even if presented to
    the jury, would only be marginally relevant to the peti-
    tioner’s self-defense claim because ‘‘it was the reason-
    ableness of the petitioner’s subjective perception of
    the situation, as he saw it, not the perception of the
    other witnesses, that was relevant to the issue of self-
    defense.’’ In other words, Polan did not need to demon-
    strate that the victim in fact had a gun, only that the
    petitioner reasonably believed him to be armed.
    Finally, it must be noted that Polan’s overall perfor-
    mance included presenting a defense that resulted in
    the petitioner’s acquittal of murder, the most serious
    charge he was facing. The United States Supreme Court
    has observed that ‘‘while in some instances even an
    isolated error can support an ineffective-assistance
    claim if it is sufficiently egregious and prejudicial . . .
    it is difficult to establish ineffective assistance when
    counsel’s overall performance indicates active and
    capable advocacy.’’ (Citation omitted; internal quota-
    tion marks omitted.) Harrington v. Richter, 
    562 U.S. 86
    , 111, 
    131 S. Ct. 770
    , 
    178 L. Ed. 2d 624
     (2011). It is
    hard to label Polan’s efforts on behalf of the petitioner
    as ineffective advocacy when those efforts resulted in
    a significant reduction in the petitioner’s potential sen-
    tencing exposure through his acquittal on the murder
    charge. If the petitioner had been convicted of murder,
    he faced a sentence ranging from the mandatory mini-
    mum of twenty-five years to a maximum of life in prison.
    See General Statutes § 53a-35a (2). Instead, his man-
    slaughter with a firearm conviction carried a lesser
    penalty, a five year mandatory minimum with a maxi-
    mum sentence of forty years of incarceration. General
    Statutes § 53a-35a (5).
    On the basis of our plenary review of the record
    presented to the habeas court, we conclude that, with-
    out resorting to impermissible speculation, the record
    contains insufficient evidence from which to gauge
    whether Polan employed reasonable efforts to investi-
    gate the shooting to locate relevant witnesses in support
    of the petitioner’s self-defense claim or whether she
    had strategic reasons for deciding not to call a particular
    witness to testify at trial.15 Because the petitioner has
    the burden of proof, that evidentiary lacuna must be
    resolved in favor of the respondent.
    Because we agree with the respondent that the
    habeas court improperly determined that Polan pro-
    vided deficient performance with respect to the peti-
    tioner’s self-defense claim, we need not address the
    respondent’s additional argument that the habeas court
    also improperly determined that the petitioner proved
    prejudice relative to the issue of self-defense. Because,
    however, the habeas court’s decision to grant the peti-
    tion for habeas corpus was also founded on Polan’s
    alleged ineffective assistance in failing to pursue a third-
    party culpability defense, we turn to the respondent’s
    next claim.
    III
    The respondent also claims that the habeas court
    improperly determined that Polan rendered deficient
    performance because she failed to pursue a third-party
    culpability defense. Specifically, the respondent claims
    that the court improperly relied on its own opinion
    regarding the viability of a third-party culpability
    defense centered on the victim’s brother, Mookie, rather
    than entertaining the possibility that a competent attor-
    ney, after careful consideration of the law and available
    evidence, reasonably might have disagreed with the
    habeas court’s assessment and considered the theory
    either too weak to present to a jury or having the poten-
    tial to muddy or otherwise undermine the defense that
    she chose to pursue, which ultimately resulted in an
    acquittal on the most serious charge of murder. We
    agree with the respondent that, in light of the record
    presented, which, despite not seeking a third-party cul-
    pability instruction, includes the undisputed fact that
    Polan argued to the jury the possibility that the victim
    was killed by a bullet fired by someone other than the
    defendant, the habeas court improperly determined that
    Polan had provided ineffective assistance with respect
    to a third-party culpability defense.
    We begin with a brief review of the standards govern-
    ing the admissibility of third-party culpability evidence
    and the requirements that must be met to obtain an
    instruction on third party culpability. ‘‘It is well estab-
    lished that a defendant has a right to introduce evidence
    that indicates that someone other than the defendant
    committed the crime with which the defendant has been
    charged. . . . The defendant must, however, present
    evidence that directly connects a third party to the
    crime. . . . It is not enough to show that another had
    the motive to commit the crime . . . nor is it enough
    to raise a bare suspicion that some other person may
    have committed the crime of which the defendant is
    accused. . . .
    ‘‘The admissibility of evidence of [third-party] culpa-
    bility is governed by the rules relating to relevancy.
    . . . In other words, evidence that establishes a direct
    connection between a third party and the charged
    offense is relevant to the central question before the
    jury, namely, whether a reasonable doubt exists as to
    whether the defendant committed the offense. Evi-
    dence that would raise only a bare suspicion that a
    third party, rather than the defendant, committed the
    charged offense would not be relevant to the jury’s
    determination.’’ (Citations omitted; internal quotation

    thermore, even if a witness’ testimony might have sup-
    ported a third-party culpability defense, this court on
    other occasions has concluded that defense counsel
    did not engage in deficient performance by failing to
    raise the defense or to call witnesses to testify in
    instances in which jurors likely would have found the
    testimony unreliable, inconsistent, or unpersuasive in
    light of the state’s evidence against the petitioner. See,
    e.g., Floyd v. Commissioner of Correction,

    , 531–32,

    mance because inconsistent testimony regarding iden-
    tity of third party), cert. denied,

    , 
    759 A.2d 1024
     (2000).
    The following additional facts are relevant to this
    claim. At trial, there was uncontested evidence that,
    shortly before the petitioner fired his weapon at the
    victim, someone nearby, other than the petitioner, had
    fired a shot. Williams’ testimony at trial suggested that
    the shooter was Wright, although other witnesses testi-
    fied that Wright was not present when the first shot
    was fired. As previously indicated, Jones had provided
    the defense with a statement suggesting that Mookie
    had fired the first shot. The medical examiner testified
    at trial that the bullet that killed the victim had entered
    his skull at a point behind his ear and exited through
    his forehead. The evidence was uncontested that the
    petitioner was standing directly in front of the victim
    just prior to him firing his gun.
    Here, although Polan did not request a specific
    instruction on third-party culpability, she nevertheless
    strongly argued the essence of such a defense to the
    jury. Accordingly, we reject any notion that she failed
    to pursue the defense outright. In her closing argument,
    Polan effectively attempted to shift blame away from
    the petitioner and toward a third-party assailant by
    arguing to the jury on the basis of the forensic evidence
    presented that there was reasonable doubt that the
    bullet that killed the victim was fired by the petitioner.
    Specifically, she highlighted the fact that the bullet that
    killed the victim had entered the skull from behind the
    victim’s right ear whereas all the witnesses had placed
    the petitioner standing directly in front of the victim at
    the time the victim was shot. If the jury believed that
    theory, or if it had created reasonable doubt in the jury’s
    mind about the identity of the shooter, it could have
    resulted in an acquittal irrespective of whether Polan
    elected to request an instruction to the jury regarding
    third party culpability.
    Moreover, there are a number of possible reasons
    why Polan may have chosen to present the third-party
    culpability defense in the manner that she did, including
    choosing to forgo seeking a third-party culpability
    instruction from the court. Polan reasonably might have
    believed that it would be easier to establish, on the
    basis of the forensic evidence, reasonable doubt as to
    whether the bullet that killed the victim had been fired
    by the petitioner rather than attempting to satisfy the
    more rigid requirements necessary for entitlement to a
    third-party culpability instruction. See Bryant v. Com-
    missioner of Correction, supra, 
    290 Conn. 515
     (evi-
    dence of ‘‘direct connection between a third party and
    the charged offense’’ necessary for instruction on third-
    party culpability). Instead, she reasonably could have
    determined that, even in the absence of an instruction,
    she effectively could argue to the jury that an unidenti-
    fied third person caused the death of the victim rather
    than the petitioner. That strategy could have been par-
    ticularly compelling in a case like the present one in
    which there were conflicting witness accounts of who
    was present, who was armed, and who may have fired
    a shot.
    Polan also reasonably may have believed that the
    third-party culpability defense was weaker than the
    petitioner’s self-defense claim, and that, even if she
    were able to convince the court to give an instruction
    on third-party culpability, it may have unnecessarily
    distracted the jury from what she believed were more
    compelling arguments. The state, after all, had strong
    evidence to counter a third-party culpability narrative.
    All the witnesses testified that the victim did not fall
    to the ground until after the petitioner fired his gun,
    suggesting it was his shot, and not the first shot fired,
    that struck and killed the victim. Furthermore, Steven-
    son, Williams and the petitioner himself testified at the
    criminal trial that the victim had begun to turn or move
    away from the petitioner at the time the petitioner fired
    his gun, which could have explained away the forensic
    evidence that was central to the success of any third-
    party culpability claim. Thus, although not abandoning
    it completely, Polan chose not to make it more of a
    focus of her closing argument and risk confusing or
    alienating the jury.
    Finally, as we have discussed already with respect
    to the petitioner’s self-defense claim, specific evidence
    of Polan’s reasons for pursuing or not pursuing any
    particular defense strategy—something generally
    obtained at the habeas trial through the testimony of
    trial counsel or someone directly familiar with her strat-
    egy—was utterly lacking. Ordinarily, such evidence is
    crucial to meet the high hurdle imposed on a petitioner
    to show that his counsel’s exercise of professional judg-
    ment fell outside the wide range considered competent
    for constitutional purposes. See O’Neil v. Commis-
    sioner of Correction, 
    142 Conn. App. 184
    , 190–91, 
    63 A.3d 986
     (lack of testimony by defense counsel about
    strategy was factor in determining petitioner failed to
    meet burden of demonstrating deficient performance),
    cert. denied, 
    309 Conn. 901
    , 
    68 A.3d 656
     (2013). Like the
    claim of ineffective assistance regarding self-defense,
    because the petitioner bears the burden of demonstra-
    ting that counsel’s representation was deficient, the
    habeas court was required to consider whether Polan’s
    decision not to pursue a formal third-party culpability
    instruction might be viewed as a reasonable strategic
    decision under the facts and circumstances of this case
    as viewed from the position of counsel at the time of
    the decision. The habeas court failed to conduct this
    inquiry and made no relevant factual findings.
    To summarize, we agree with the respondent that the
    habeas court, in analyzing whether Polan’s performance
    fell outside the wide range of competent performance,
    failed affirmatively to entertain whether Polan properly
    had weighed the pros and cons of various trial strategies
    and chose to defend the petitioner in a manner different
    than the strategy the habeas court thought she should
    have pursued. Although the death of counsel arguably
    made the petitioner’s case more difficult to prove than
    it might otherwise have been, that unfortunate reality
    does not lessen the petitioner’s significant burden.
    Because the petitioner was unable, due to a lack of
    evidence, to negate all possibility that Polan engaged
    in a reasonable, albeit only partially successful, defense
    strategy on the record available, he failed to meet his
    burden and the habeas court should have denied his
    petition for a writ of habeas corpus.
    The judgment is reversed and the case is remanded
    with direction to deny the petition for a writ of
    habeas corpus.
    In this opinion the other judges concurred.
    1
    Specifically, the court sentenced the petitioner to the maximum permit-
    ted sentence of five years of imprisonment on the weapons charge, a class
    D felony; see General Statutes §§ 29-37 (b) and 53a-35a (8); which was
    ordered to run consecutively to the forty year maximum sentence of incarcer-
    ation that the court imposed for the manslaughter charge. See General
    Statutes § 53a-35a (5).
    2
    In particular, this court concluded that the prosecutor improperly had
    argued to the jury that the jury could infer the defendant’s intent from the
    ‘‘extra effort’’ and ‘‘more conscious action’’ it takes to fire a revolver rather
    than a semiautomatic pistol because the state’s firearms expert never testi-
    fied to those particular facts. State v. Jordan, 
    supra,
     
    117 Conn. App. 166
    .
    This court also concluded that, under the circumstances presented, the
    prosecutor’s repetitive use of the rhetorical phrase ‘‘doesn’t it offend your
    common sense’’ was improper. Id., 167. Despite those improprieties, how-
    ever, this court determined on the basis of our analysis of the various factors
    set forth in State v. Williams, 
    204 Conn. 523
    , 535–40, 
    529 A.2d 653
     (1987),
    that the defendant was not deprived of his right to a fair trial. See State v.
    Jordan, 
    supra,
     168–70.
    3
    The habeas court permitted the petitioner to withdraw the two prior
    habeas petitions without prejudice, both times just before the start of a trial
    on the merits. The petitioner also filed a fourth habeas petition subsequent
    to the present petition in which he alleged that the respondent had entered
    into, and subsequently breached, an agreement to award him certain earned
    risk reduction credits. That fourth petition was dismissed by the habeas
    court. See Jordan v. Commissioner of Correction, 
    190 Conn. App. 557
    , 558,
    
    211 A.3d 115
     (affirming judgment of habeas court on ground that petition
    had failed to implicate cognizable liberty interest sufficient to invoke subject
    matter jurisdiction of habeas court), cert. denied,

     (1963).
    5
    The respondent also raised the defense of abuse of the writ. In support
    of that defense, the respondent asserted that the petitioner raised the same
    issues in the current habeas petition that he had raised in two prior petitions,
    each of which he had withdrawn on the day trial was scheduled to com-
    mence, purportedly due to the unavailability of witnesses. ‘‘Decisions con-
    cerning abuse of the writ are addressed to the sound discretion of the trial
    court.’’ James L. v. Commissioner of Correction, 
    245 Conn. 132
    , 143, 
    712 A.2d 947
    , 953 (1998); see 
    id.,
     140 n.8 (noting that successive petitions are
    not necessarily abuse of writ but declining to ‘‘delineate how these two
    habeas doctrines differ or overlap’’). The respondent did not pursue the
    abuse of the writ defense in his posttrial brief, and the habeas court did
    not address that defense in its decision on the merits. Because the respondent
    has not raised abuse of the writ as an issue on appeal, we deem it abandoned.
    6
    As part of his preliminary papers on appeal, the petitioner raised as an
    alternative ground for affirmance pursuant to Practice Book § 63-4 (a) (1)
    that the habeas court also should have granted the petition on the basis of
    Polan’s having allowed her chief investigator, O’Donnell, to assist her at
    counsel table during the trial. The habeas court had found that Polan’s
    decision to allow O’Donnell to sit at counsel table was unreasonable as a
    defense strategy and, thus, amounted to deficient performance, because, as
    a result of the criminal court’s sequestration order, Polan was precluded
    from calling O’Donnell to impeach a witness who testified at trial inconsis-
    tently with a pretrial statement made to O’Donnell. The habeas court, how-
    ever, concluded that the petitioner had failed to demonstrate that he was
    unduly prejudiced by Polan’s decision. Because the petitioner did not brief
    this alternative ground for affirmance in his appellee’s brief, we deem it
    abandoned. See State v. Rowe, 
    279 Conn. 139
    , 143 n.1, 
    900 A.2d 1276
     (2006).
    7
    The respondent filed a petition for certification to appeal on October
    15, 2018. The habeas court initially denied the petition on October 16, 2018,
    without explanation. In response to that ruling, the respondent filed a motion
    for articulation asking the court to state the basis for its denial of the
    petition for certification. In that motion, the respondent sought to excuse
    any perceived delay in the filing of the petition by noting that counsel for
    the respondent had been out of the country, that counsel was informed by
    the clerk’s office that it measured the ten day filing period governing petitions
    for certification to appeal as set forth in General Statutes § 52-470 (g) by
    counting business days, not calendar days (which would mean the October
    15, 2018 petition was timely filed), and that counsel filed the petition immedi-
    ately after returning to the office. The habeas court, in response to the
    motion for articulation, issued an order on October 25, 2018, vacating its
    prior order and granting the respondent’s petition for certification to appeal.
    The court explained that, although, in its view, it properly had interpreted
    the ten day statutory filing deadline to mean ten calendar days, it nonetheless
    had reconsidered its earlier ruling in light of the facts set forth in the
    motion for articulation and because the time period for filing a petition
    for certification to appeal is not jurisdictional in nature. See Iovieno v.
    Commissioner of Correction, 
    242 Conn. 689
    , 700, 
    699 A.2d 1003
     (1997)
    (holding that whether to entertain untimely petition for certification fell
    within court’s discretion, to be exercised after considering reasons for
    delay).

    ‘‘[T]he state and federal constitutional standards for review of ineffective
    assistance of counsel claims are identical’’ and the rights afforded are ‘‘essen-
    tially coextensive’’ in nature and, thus, do not require separate analysis.

    Because we determine on the basis of our plenary review that the peti-
    tioner failed to satisfy his burden under the performance prong of Strickland,
    it is unnecessary for us to reach the respondent’s claim that the petitioner
    also failed to satisfy the prejudice prong. See Antwon W. v. Commissioner
    of Correction, supra, 
    172 Conn. App. 858
    .

    The criminal trial court’s detailed instructions to the jury on self-defense
    included the following instructions pertaining to the initial aggressor excep-
    tion to self-defense as well as the statutory duty to retreat. ‘‘The initial
    aggressor is the person who first acts in such a manner that creates a
    reasonable belief in another person’s mind that physical force is about to
    be used upon that other person. The first person to use physical force is
    not necessarily the initial aggressor.
    ‘‘Before an initial aggressor can . . . use any physical force, the initial
    aggressor must withdraw or abandon the conflict in such a way that the
    fact of withdrawal is perceived by his opponent so that such opponent is
    aware that there is no longer any danger from the original aggression.
    ‘‘If the initial aggressor so withdraws or abandons the conflict and his
    opponent not withstanding continues or threatens the use of physical force,
    the initial aggressor may be justified in using physical force to defend himself.
    ‘‘If you find that the state has proven beyond a reasonable doubt that the
    defendant was the initial aggressor and that the defendant did not effectively
    withdraw from the encounter or abandon it in such a way that his opponent
    knew he was no longer in any danger from the defendant, you shall then
    find the defendant was not justified in using any physical force.
    ***
    ‘‘[A] person is not justified in using deadly physical force upon another
    person if he knows he can avoid the necessity of using such force by
    retreating with complete safety. This means that retreat was both completely
    safe . . . and available and that the defendant knew it.
    ‘‘Completely safe means without any injury to him whatsoever. As I have
    said, self-defense requires you to focus on the person claiming self-defense,
    on what he reasonably believed under the circumstances, and it presents
    a question of fact as to whether a retreat with complete safety was available
    and whether the defendant knew it.
    ‘‘The law stresses that self-defense cannot be retaliatory. It must be defen-
    sive and not punitive. So you must ask yourself, did the defendant know
    he could avoid the use of deadly force by retreating with complete safety?
    If so and yet he chose to pursue the use of deadly force then you shall
    reject that self-defense claim.’’
    11
    We note that the state’s theory of the case did not turn on the identity
    of who fired the first shot. Williams’ trial testimony implicated Wright without
    directly identifying him as the shooter, whereas at least one of the habeas
    witnesses indicated that the first shooter was Mookie.
    12
    Neither the transcript of Martin’s statement nor the tape recording itself,
    both of which were admitted as full exhibits at the criminal trial, was
    submitted as an exhibit at the habeas trial and, thus, any review of the
    contents of Martin’s statement is limited to that portion described on the

    Jones’ story corroborated in some respects Williams’ trial testimony
    that other participants, including the victim, were armed and that weapons

    of the witnesses presented at the habeas trial could be described as neutral
    or disinterested. They were either related to or friends with the petitioner
    and/or the victim.
