    SKAKEL v. COMMISSIONER OF CORRECTION—DISSENT
    PALMER, J., with whom McDONALD, J., joins, dis-
    senting. In the more than forty years since fifteen year
    old Martha Moxley (victim) was brutally murdered near
    her home in Greenwich, this tragic case has given rise to
    numerous investigations, suspects, petitions, hearings,
    appeals—as well as many articles, books, documenta-
    ries, and movies—and, of course, the trial that is the
    subject of this appeal. Unfortunately, none has brought
    any real closure or clarity to the case. One thing, how-
    ever, is perfectly clear: the habeas court was absolutely
    right in concluding that the petitioner, Michael Skakel,
    did not receive a fair trial because, in numerous
    respects, the representation that he received from his
    chief trial counsel, Michael Sherman, fell far below the
    range of competence necessary to satisfy the petition-
    er’s right to the effective assistance of counsel guaran-
    teed by the sixth amendment to the United States
    constitution.1 In fact, in its thorough and well reasoned
    decision, the habeas court identified ten separate and
    distinct areas in which Sherman’s performance did not
    meet professional standards. With respect to three of
    them, the court found that Sherman’s deficient perfor-
    mance was so prejudicial as to undermine confidence
    in the verdict and, therefore, require a new trial.2 I agree
    with each and every one of those determinations, which
    are fully borne out by the record.
    I address only two of them here, however, namely,
    Sherman’s manifestly incompetent and prejudicial han-
    dling of the petitioner’s alibi defense and the petitioner’s
    third-party culpability defense. The former, of course,
    involves Sherman’s failure to follow up on the grand jury
    testimony of Georgeann Dowdle, one of the petitioner’s
    alibi witnesses, that her ‘‘beau,’’ subsequently identified
    as Denis Ossorio, was with her and the petitioner at
    her home on the evening of the murder. If Sherman had
    taken the trouble simply to ask Dowdle about Ossorio,
    Sherman would have learned that Ossorio could provide
    critical, credible and independent testimony corrobo-
    rating the petitioner’s alibi, which otherwise was predi-
    cated on the testimony of only Skakel family members.
    The second issue involves Sherman’s decision to pre-
    sent a third-party culpability defense centered around
    Kenneth Littleton, even though there was no evidence—
    none—linking Littleton to the murder, and even though
    a third-party culpability defense implicating the peti-
    tioner’s brother, Thomas Skakel, in the murder, would
    have been truly compelling. I limit my analysis to these
    two areas of deficient performance because, in my view,
    it could hardly be more apparent that each one of them
    deprived the petitioner of a fair trial.
    Before commencing that review, however, I wish to
    underscore one aspect of the majority opinion, per-
    taining to the alibi issue, that is so blatantly one-sided
    as to call into question the basic fairness and objectivity
    of the majority’s analysis and conclusion. As I discuss
    more fully hereinafter, the majority concludes that Sher-
    man’s decision to forgo any inquiry into Ossorio in
    furtherance of the petitioner’s alibi defense was reason-
    able because the facts supported Sherman’s belief that
    any further investigation probably would not be produc-
    tive. See part II C of the majority opinion. Even though
    the case law is perfectly clear that all of the relevant
    facts and circumstances are to be considered in evaluat-
    ing the objective reasonableness of such a decision; see
    Strickland v. Washington, 
    466 U.S. 668
    , 691, 
    104 S. Ct. 2052
    , 
    80 L. Ed. 2d 674
     (1984) (explaining that, ‘‘[i]n
    any ineffectiveness case, a particular decision not to
    investigate must be directly assessed for reasonable-
    ness in all the circumstances’’ [emphasis added]);
    accord Gaines v. Commissioner of Correction, 
    306 Conn. 664
    , 680, 
    51 A.3d 948
     (2012); the majority’s review
    of the alibi issue begins and ends with its conclusion
    that Sherman reasonably believed that it was likely that
    no investigation into Ossorio would be fruitful. At no
    time does the majority even acknowledge, let alone eval-
    uate, the powerful, countervailing considerations that
    militate strongly in favor of the habeas court’s determi-
    nation that the sixth amendment required Sherman to
    conduct some additional investigation. These consider-
    ations are obvious, and include the paramount impor-
    tance of the petitioner’s alibi defense, the enormous
    significance of an unbiased and credible witness who
    could corroborate the alibi testimony of the Skakel
    family members, the ease with which such a witness
    promptly could have been located, and the gravity of
    the charge that the petitioner faced. I can conceive of
    only one reason why the majority refuses to take those
    highly relevant considerations into account: they are
    incompatible with the majority’s conclusion that Sher-
    man’s performance was reasonable under the circum-
    stances.3
    I
    SHERMAN’S FAILURE TO LOCATE AND INTERVIEW
    A CRITICAL ALIBI WITNESS CONSTITUTED
    DEFICIENT REPRESENTATION UNDER
    THE SIXTH AMENDMENT
    I could not disagree more with the majority’s conclu-
    sion rejecting the habeas court’s decision that Sherman
    failed to conduct a constitutionally adequate investiga-
    tion into the petitioner’s alibi defense, resulting in
    extreme prejudice to the petitioner. In fact, I believe
    that the majority’s analysis and conclusion represent an
    unprecedented and indefensible deviation from settled
    sixth amendment principles.
    As I explain hereinafter, there are a number of serious
    errors in the majority’s analysis that lead to its palpably
    wrong conclusion, but two obvious and fundamental
    flaws skew its entire analysis. First, the majority
    employs an improper legal standard in determining that
    Sherman’s handling of the petitioner’s alibi defense
    comported with the petitioner’s sixth amendment right
    to the effective assistance of counsel. More specifically,
    the majority concludes that Sherman’s failure to inter-
    view Ossorio was not constitutionally deficient because
    Sherman reasonably could have inferred from all of
    the circumstances that Ossorio would not be able to
    provide any useful testimony. Contrary to the majority’s
    decision, the sixth amendment does not permit defense
    counsel to forgo any inquiry into the testimony of a
    potentially critical witness like Ossorio merely because
    counsel thinks or believes that the witness will not be
    helpful; counsel has a duty to his client to take reason-
    able steps to find out what the witness knows, and not
    to rely on inference, belief or educated guess. Indeed,
    federal courts are unanimous on this point. Consistent
    with that precedent, one searches the majority opinion
    in vain for a case with contrary reasoning, or one that
    presents a fact pattern even remotely similar to this
    case, in which the petitioner was not awarded a new
    trial. I submit that none exists.
    Second, as I mentioned previously, the majority con-
    siders only those factors that support its conclusion
    justifying Sherman’s failure to follow up on Dowdle’s
    testimony, and chooses to ignore all of the compelling
    considerations that militate in favor of the habeas
    court’s determination that Sherman had a clear duty to
    undertake a further inquiry into Dowdle’s ‘‘beau.’’ By
    any fair measure, Sherman’s decision to simply disre-
    gard Dowdle’s grand jury testimony and to make no
    effort to find Ossorio was particularly unreasonable
    and professionally irresponsible under the facts and
    circumstances that the majority simply ignores. The
    charge that the petitioner faced—murder, which carried
    a maximum sentence of life imprisonment—could not
    be more serious, and the importance of corroborative
    alibi testimony—from an independent, nonfamily mem-
    ber witness like Ossorio—cannot be overstated. Sher-
    man reasonably could not have ruled out the possibility
    that Ossorio would be able to provide such testimony,
    and he would have confirmed that Ossorio could, in
    fact, do so merely by asking Dowdle to identify her
    ‘‘beau,’’ who, at that time, lived within miles of Sher-
    man’s law office, and then by contacting Ossorio, who
    was ready, willing and able to testify—credibly, as the
    habeas court found—on the petitioner’s behalf. As the
    United States Supreme Court has observed in a case
    involving this very issue, ‘‘[w]hen viewed in this light,
    the ‘[reasonable] decision’ the [majority and the state
    both] invoke to justify counsel’s [failure to pursue] miti-
    gating evidence resembles more a post hoc rationaliza-
    tion of counsel’s conduct than an accurate description
    of their deliberations prior to [trial].’’ Wiggins v. Smith,
    
    539 U.S. 510
    , 526–27, 
    123 S. Ct. 2527
    , 
    156 L. Ed. 2d 471
     (2003).
    Not surprisingly, both Sherman and his associate,
    Jason Throne, testified without contradiction that an
    objective and unbiased witness would have been critical
    to the petitioner’s alibi defense, and that they were very
    eager to locate a witness who met that profile. And yet,
    when Sherman and Throne learned by reading the grand
    jury testimony of their own witness, Dowdle, that just
    such an independent and unbiased witness—her former
    ‘‘beau’’—was at the home of James Terrien, with Dow-
    dle, on the evening of October 30, 1975, they did nothing
    in response to that testimony. Nevertheless, the major-
    ity concludes that Sherman and Throne reasonably
    decided that it just was not worth the effort to follow
    up on Dowdle’s testimony, even though it would have
    entailed nothing more than a couple of telephone calls.
    It is perplexing, to say the least, that the majority
    endorses an investigative approach that reflects such
    a gross lack of attention and effort, one that created
    such a serious and needless risk that the petitioner’s
    case would be severely prejudiced because of counsel’s
    cavalier refusal to pursue a potentially critical lead. In
    fact, I cannot fathom why the majority sets the bar so
    low, or why it employs such a skewed and one-sided
    analysis in doing so.
    A
    The Facts
    The relevant facts and procedural history pertaining
    to this issue are largely undisputed. Within hours of the
    discovery of the victim’s body around 12:30 p.m. on
    October 31, 1975, the police began interviewing those
    persons who might be able to provide useful informa-
    tion about the events surrounding the victim’s murder.
    In one of those interviews, Thomas Skakel informed
    the police that he had been with the victim until approxi-
    mately 9:30 p.m. on October 30, at which time both
    of them departed for their respective homes. Thomas
    Skakel also told the police that, at about that same
    time, the petitioner left for the Terrien home, which is
    about a twenty minute car ride from the Skakel home,
    in Thomas Skakel’s father’s Lincoln Continental,
    accompanied by his brothers John Skakel and Rushton
    Skakel, Jr., and their cousin, Terrien.4 In his interview
    with the police, the petitioner also stated that he had
    gone to the Terrien home around 9:30 p.m., watched
    television there, and did not return home until approxi-
    mately 11 p.m. Interview reports of others who were
    questioned by the police soon after the discovery of
    the victim’s body do not indicate whether those persons
    were questioned about the activities and whereabouts
    of Thomas Skakel and the petitioner in the general time
    frame of the murder. In the weeks following the murder,
    however, everyone who expressed any knowledge
    about the comings and goings of the petitioner and
    Thomas Skakel corroborated the statements that they
    had given to the police. Among those who did so in
    their police interviews were John Skakel, Rushton Ska-
    kel, Jr., and Terrien. In addition, Terrien’s sister, Dow-
    dle, told the police that the petitioner was at the Terrien
    home (where she resided) on the evening of October
    30, 1975, along with her brother and her cousins, John
    Skakel and Rushton Skakel, Jr.
    Shortly after the murder, the prime suspect in the
    victim’s death was Thomas Skakel, for whom the Green-
    wich police sought permission from the Office of the
    State’s Attorney to apply for an arrest warrant. Permis-
    sion was denied because the state’s attorney did not
    believe that the evidence set forth in the warrant appli-
    cation and affidavit constituted probable cause to
    believe that Thomas Skakel had committed the murder.
    Although the investigation into the victim’s death con-
    tinued for some time,5 the petitioner did not become a
    suspect until sometime in the mid-1990s. As a conse-
    quence, for at least twenty years following the victim’s
    death, investigators had no reason to focus their atten-
    tion on the petitioner or his activities, and did not do so.
    Apparently prompted by information gleaned from a
    report prepared by Sutton Associates, a private security
    firm, sometime in the mid-1990s,6 those investigators
    undertook to develop a case against the petitioner.
    Because of this investigation, in July, 1998, the peti-
    tioner retained Sherman to represent him.
    In connection with that renewed investigation, a
    grand jury was empaneled at the state’s request for
    the purpose of acquiring additional evidence about the
    murder and, in particular, evidence linking the peti-
    tioner thereto. Numerous people were called to appear
    before the grand jury, one of whom was Dowdle. On
    September 22, 1998, she testified before the grand jury
    under oath that she was home on the evening of October
    30, 1975, when her brother, Terrien, and cousins, the
    Skakels, arrived around 9:30 p.m. to watch television.
    Because she was in her mother’s library putting her
    daughter to bed, and Terrien and the Skakels were in
    a room located off the library, she could say only that
    she heard the Skakels’ voices but could not recall, given
    the passage of time, whether she actually saw the peti-
    tioner. Dowdle also testified, however, that, when inter-
    viewed by the police shortly after the murder, she told
    them that the petitioner had been at her home that
    evening. She further testified that her ‘‘beau’’ was with
    her that evening at her home. Sherman, however, never
    followed up on Dowdle’s testimony that she had a com-
    panion, her ‘‘beau,’’ that evening.
    Following completion of the grand jury investigation,
    in January, 2000, the petitioner was charged with the
    victim’s murder, and the petitioner’s criminal trial com-
    menced in early May, 2002. In their trial testimony in
    support of the petitioner’s alibi defense, Rushton Ska-
    kel, Jr., and Terrien explained, consistent with their
    grand jury testimony and the statements that they had
    given to the police some twenty-seven years earlier,
    that they and the petitioner, along with John Skakel,
    had driven to the Terrien residence at around 9:30 p.m.
    on October 30, 1975, remained there until about 11 p.m.,
    and then returned home. John Skakel also testified at
    trial but stated that he could not recall whether the
    petitioner had gone to the Terrien home that evening.
    When asked, however, whether the statement he had
    given to the police soon after the murder accurately
    reflected what he knew at the time—that is, that the
    petitioner was at the Terrien home with other family
    members that evening—John Skakel responded in the
    affirmative. Finally, Dowdle’s trial testimony mirrored
    her grand jury testimony. In fact, during questioning of
    Dowdle by State’s Attorney Jonathan Benedict about
    her grand jury testimony, Dowdle expressly reiterated
    that a ‘‘friend’’ was with her at the Terrien home on the
    evening of October 30, and, in addition, while she was
    still on the stand, a portion of her grand jury testimony
    containing the reference to her ‘‘beau’’ was read and
    published to the jury. Again, Sherman took no action
    with respect to the identity, availability or potential
    testimony of Dowdle’s ‘‘beau.’’
    Benedict sought to rebut the petitioner’s alibi defense
    with the testimony of three witnesses, Helen Ix, Andrea
    Shakespeare, and Julie Skakel, all of whom were pres-
    ent at the Skakel residence from approximately 9 to
    9:30 p.m. on October 30, 1975. Ix and the victim, Ix’
    close friend, had gone to the Skakel home together,
    arriving shortly after 9 p.m. Ix remained there until
    approximately 9:30 p.m., when she left and went home.
    On direct examination, Ix testified that she was uncer-
    tain whether the petitioner was in the car when it
    headed for the Terrien residence; on cross-examination,
    however, she indicated that she thought that he was in
    the car, but she was not sure in light of the passage
    of time.
    Shakespeare, a good friend of Julie Skakel’s, had
    been with the Skakel family at dinner that evening and
    returned with the family members to the Skakel resi-
    dence at about 9 p.m. Initially, on direct examination
    by the state, Shakespeare asserted that the petitioner
    had remained at home when the Skakel brothers left
    for the Terrien residence. Thereafter, however, upon
    being recalled to testify by Sherman, she acknowledged
    that she had given a tape-recorded statement to the
    police in 1991, the relevant portion of which was played
    for the jury, in which she stated that she did not see
    the car when it left for the Terrien residence and that
    she therefore did not see whether the petitioner was
    in the car. She further told the police that, although she
    believed that the petitioner had gone to the Terrien
    residence, she had no independent recollection of the
    events in question and that her belief was based on
    what others had told her had occurred on the evening
    of October 30, 1975.
    Finally, Julie Skakel, the petitioner’s sister, testified
    that she was uncertain about the events of that evening.
    In light of that testimony, the state was permitted to
    introduce a statement that she had made in a prior
    proceeding in which she stated that, at around 9:20 p.m.
    on October 30, 1975, she saw an unidentified person
    run by, just outside a window in the Skakel residence,
    and that she called out, ‘‘Michael, come back here.’’
    The significance of this testimony was to demonstrate
    that, at least at that moment in time, Julie Skakel
    believed that the figure she observed through the win-
    dow was the petitioner.
    At the conclusion of the evidence, Benedict, in his
    closing argument to the jury, acknowledged that the
    petitioner’s proffered alibi was the ‘‘cornerstone of the
    defense . . . .’’ In fact, according to Benedict, the alibi
    was the key component of a scheme, hatched by the
    petitioner’s father, Rushton Skakel, Sr., and furthered
    by the entire Skakel family, all of whom, Benedict
    alleged, siblings and cousins alike, knew that the peti-
    tioner had murdered the victim, to shield the petitioner
    from the consequences of his heinous crime. Benedict
    argued that the family plot to protect the petitioner
    commenced ‘‘on October 30, 1975, with the disappear-
    ance . . . [and] disposal’’ of incriminating evidence,
    including ‘‘the golf club, the shaft and any other evi-
    dence of the crime’’ within ‘‘thirty-six hours’’ of its com-
    mission. The cover-up continued the day after the
    murder, when Littleton was ‘‘ordered’’ to take the peti-
    tioner, Thomas Skakel, John Skakel, and Terrien for an
    overnight visit to the Skakel family home in Windham,
    New York, the place where the conspiracy allegedly
    ‘‘took shape.’’ In the state’s view, the family’s effort to
    ‘‘advance’’ this ‘‘produced’’ and ‘‘concocted’’ alibi con-
    tinued during the grand jury proceedings and at the
    petitioner’s criminal trial, at which the petitioner’s wit-
    nesses all gave intentionally false testimony in asserting
    that the petitioner was at the Terrien residence when,
    according to the great weight of the evidence, the victim
    was being murdered. Finally, Benedict repeatedly and
    forcefully reminded the jurors that the petitioner’s alibi
    witnesses were all family members, emphasizing that
    ‘‘[n]o independent witness [could] say what happened
    once [the] Lincoln [Continental] backed out of the drive-
    way’’ of the Skakel home at about 9:15 p.m. on October
    30, 1975. Benedict’s argument evidently was convincing,
    because the jury, after expressly requesting that the
    testimony of Ix, Shakespeare and Julie Skakel be read
    back—the only testimony offered by the state that even
    arguably tended to refute the petitioner’s alibi—found
    the petitioner guilty.7
    Thereafter, following an unsuccessful appeal from

    295 Conn. 447
    , 452, 
    991 A.2d 414
     (2010); the petitioner
    commenced the present habeas action. I now briefly
    summarize testimony from the habeas trial that is perti-
    nent to the petitioner’s contention that Sherman failed
    to conduct a constitutionally adequate investigation of
    his alibi defense.
    The petitioner elicited testimony from Ossorio, a psy-
    chologist who was seventy-two years old at the time
    of the habeas trial, that he was visiting Dowdle at the
    Terrien residence during the evening of October 30,
    1975, and until around midnight on October 31, and
    that the petitioner and several others also were there
    that evening, watching television in the library. Ossorio
    testified that, although he was visiting Dowdle, who
    was caring for her child, he ‘‘was in and out’’ of the
    room in which the petitioner and the others who were
    there that evening were watching television. Ossorio,
    who further testified that he resided in Greenwich at
    the time of the petitioner’s criminal trial, stated that
    neither the police nor the defense had ever sought to
    interview him regarding his presence at the Terrien
    residence on that date, and that he had never come
    forward because he did not pay close enough attention
    to the trial to appreciate that his presence at the Terrien
    residence, and his recollection of the evening’s events,
    would have been important to the case. The habeas
    court expressly credited Ossorio, who it characterized
    as a ‘‘disinterested,’’ ‘‘powerful,’’ and ‘‘credible’’ witness.
    The petitioner also presented the testimony of
    Michael Fitzpatrick, a prominent Connecticut attorney
    and past president of the Connecticut Criminal Defense
    Lawyers Association who specializes in criminal
    defense and civil litigation. Fitzpatrick testified that he
    had spent more than 200 hours reviewing all of the
    transcripts and other materials relevant to the petition-
    er’s habeas claims, and, on the basis of his expertise
    and experience in the field of criminal law, it was his
    opinion that a reasonably competent criminal defense
    attorney, after receiving and reviewing Dowdle’s grand
    jury testimony, ‘‘absolutely’’ would have ascertained
    Ossorio’s identity and then made reasonable efforts to
    locate and interview him. That investigation was
    required, according to Fitzpatrick, because it was
    incumbent on Sherman to confirm that Ossorio was
    present at the Terrien residence on October 30, 1975,
    and, if so, whether his recollection of the events would
    strengthen the petitioner’s alibi defense. In particular,
    Fitzpatrick explained that, if Ossorio recalled that the
    petitioner was present at the Terrien home that evening,
    that testimony would have ‘‘[made] it impossible for
    the state to argue in summation that there [was] not a
    single independent [alibi] witness in the case, which
    was one of the chief grounds the state asserted for
    rejecting the alibi.’’ Fitzpatrick further testified that
    Sherman’s failure to identify and interview Ossorio
    ‘‘absolutely prejudiced’’ the petitioner because ‘‘it
    deprived [him] . . . of the opportunity to present an
    independent alibi witness, and we know by way of fact
    . . . that he was convicted, [and] that the jury unani-
    mously rejected the alibi.’’
    Throne, an associate in Sherman’s office who served
    as cocounsel for the petitioner along with Sherman,
    also was a witness at the habeas trial. Among other
    subjects, Throne testified about the petitioner’s alibi,
    explaining that it was ‘‘extremely important’’ to the
    petitioner’s overall defense of the charge against him.
    When asked if the petitioner’s trial counsel were ‘‘eager
    to find anyone who could corroborate [the alibi],’’
    Throne responded, ‘‘[a]bsolutely, without question.’’
    Throne further stated that, ‘‘even more importantly,’’
    the petitioner’s counsel were ‘‘especially eager to find
    a nonfamily member who could corroborate [the peti-
    tioner’s alibi].’’ He elaborated on that testimony by not-
    ing the ‘‘obvious concern’’ that the petitioner’s counsel
    had because all of the alibi witnesses were family mem-
    bers, and because of the likelihood that ‘‘the jury would
    perceive all of those witnesses as having bias and a
    motivation to lie or distort facts or truth, which wasn’t
    the case. . . . I wish that we had even a single witness
    that wasn’t blood related to include in that group that
    could have testified to the same facts that everyone
    else testified to, to establish that [the petitioner] was
    not there the night of the murder.’’ According to Throne,
    the testimony of an independent, nonfamily alibi wit-
    ness would have been ‘‘critical’’ to the petitioner’s
    alibi defense.
    Finally, Sherman testified at the habeas trial. When
    asked whether the alibi was the petitioner’s ‘‘principal
    defense’’ at his criminal trial, Sherman responded,
    ‘‘[a]bsolutely,’’ and, thereafter, characterized the alibi
    defense as ‘‘our mainframe.’’ He also stated that it would
    have been ‘‘very important’’ to have an alibi witness
    who was not related to the petitioner and that, if he had
    located one, he would have had him testify in support of
    the petitioner’s alibi, ‘‘[w]ithout a doubt.’’ In response
    to questioning from the state, and with reference to
    Dowdle’s grand jury testimony, Sherman indicated that,
    because Dowdle had testified that she ‘‘really didn’t
    venture out’’ of the library on the evening of October
    30, 1975, Ossorio, her guest, might well have stayed in
    the library, as well. Sherman further agreed that,
    because Dowdle recalled hearing but not seeing the
    Skakel relatives in a nearby room, Ossorio also may
    not have seen the Skakels. Sherman also acknowledged
    that he had read Dowdle’s grand jury testimony prior
    to trial, testimony that included her statement that her
    ‘‘beau’’ was with her that evening at the Terrien home.
    When Sherman was asked why he had never inquired
    into the identity of Dowdle’s ‘‘beau,’’ Sherman explained
    simply that, ‘‘I had no reason to suspect that he, in fact,
    would be helpful in that he saw [the petitioner] and the
    rest of the boys.’’

    The Applicable Law
    As the majority notes, the sixth amendment guaran-
    tees criminal defendants the effective assistance of
    counsel; Strickland v. Washington, 
    supra,
     
    466 U.S. 687
    ;
    and that guarantee ‘‘is beyond question a fundamental
    right.’’ Kimmelman v. Morrison, 
    477 U.S. 365
    , 377, 
    106 S. Ct. 2574
    , 
    91 L. Ed. 2d 305
     (1986). ‘‘The [s]ixth [a]mend-
    ment recognizes [this right] because it envisions [that
    counsel will play] a role that is critical to the ability of
    the adversarial system to produce just results.’’ (Inter-
    nal quotation marks omitted.) 
    Id., 394
    . ‘‘[C]ounsel’s
    function, as elaborated in prevailing professional
    norms, is to make the adversarial testing process work
    in the particular case.’’ (Internal quotation marks omit-
    ted.) 
    Id., 384
    . Consequently, ‘‘[a]n accused is entitled
    to be assisted by an attorney, whether retained or
    appointed, who plays the role necessary to ensure that
    the trial is fair.’’ (Internal quotation marks omitted.)
    
    Id., 377
    .
    These general principles are no less applicable to the
    investigative stage of a criminal case than they are to
    the trial phase. Indeed, the United States Supreme Court
    has explained that the foregoing ‘‘standards require no
    special amplification in order to define counsel’s duty
    to investigate . . . . [Simply stated], strategic choices
    made after less than complete investigation are reason-
    able 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 unnecessary.’’ Strick-
    land v. Washington, 
    supra,
     
    466 U.S. 690
    –91. That is,
    counsel’s decision to forgo or truncate an investigation
    ‘‘must be directly assessed for reasonableness in all
    the circumstances . . . .’’ 
    Id., 691
    . ‘‘In assessing the
    reasonableness of an attorney’s investigation . . . a
    court must consider not only the quantum of evidence
    already known to counsel, but also whether the known
    evidence would lead a reasonable attorney to investi-
    gate further.’’ Wiggins v. Smith, 
    supra,
     
    539 U.S. 527
    . In
    addition, in contrast to our evaluation of the constitu-
    tional adequacy of counsel’s strategic decisions, which
    are entitled to deference, when the issue is whether ‘‘the
    investigation supporting counsel’s [strategic] decision’’
    to proceed in a certain manner ‘‘was itself reasonable’’;
    (emphasis altered) id., 523; ‘‘we must conduct an objec-
    tive review of [the reasonableness of counsel’s] perfor-
    mance . . . .’’ (Emphasis added.) Id. Thus, ‘‘deference
    to counsel’s strategic decisions does not excuse an inad-
    equate investigation . . . .’’ Williams v. Stephens, 
    575 Fed. Appx. 380
    , 386 (5th Cir.), cert. denied,        U.S.
    , 
    135 S. Ct. 875
    , 
    190 L. Ed. 2d 709
     (2014). Finally,
    because a thorough pretrial investigation is so often an
    essential component of the defense of a criminal case—
    especially if the case is complex or involves particularly
    serious charges—‘‘[c]ourts have not hesitated to find
    ineffective assistance in violation of the [s]ixth [a]mend-
    ment when counsel fails to conduct a reasonable inves-
    tigation into one or more aspects of the case and when
    that failure prejudices his or her client.’’ Towns v.
    Smith, 
    395 F.3d 251
    , 258 (6th Cir. 2005).
    Although the reasonableness of any particular investi-
    gation necessarily depends on the unique facts of any
    given case; see, e.g., Strickland v. Washington, 
    supra,
    466 U.S. 688
    –89; counsel has certain baseline responsi-
    bilities that must be discharged in every criminal matter.
    ‘‘It is the duty of the [defense] lawyer to conduct a
    prompt investigation of the circumstances of the case
    and to explore all avenues leading to facts relevant to
    the merits of the case . . . .’’ (Internal quotation marks

     (1992). This
    duty exists irrespective of whether the defendant is
    helpful to counsel by providing information pertinent
    to his defense or whether he provides no such assis-
    tance. See Rompilla v. Beard, 
    supra, 381
     (although peti-
    tioner was unwilling to assist counsel in pretrial
    preparation and ‘‘was even actively obstructive by send-
    ing counsel off on false leads,’’ counsel nevertheless
    had independent obligation to conduct thorough inves-
    tigation); Daniels v. Woodford, 
    428 F.3d 1181
    , 1202–1203
    (9th Cir. 2005) (‘‘[e]ven though [the petitioner] refused
    to speak to his counsel, [counsel] still had an indepen-
    dent duty to investigate [and prepare]’’ because ‘‘[p]re-
    trial investigation and preparation are the keys to
    effective representation of counsel’’ [internal quotation
    marks omitted]), cert. denied sub nom. Ayers v. Dan-
    iels,

    , 
    127 S. Ct. 2876
    , 
    167 L. Ed. 2d 1152
    (2007). Thus, ‘‘[a]n attorney’s duty of investigation
    requires more than simply checking out the witnesses
    that the client himself identifies.’’ Bigelow v. Haviland,
    
    576 F.3d 284
    , 288 (6th Cir. 2009); see also 
    id.,
     288–89
    (‘‘[Defense counsel] had no reasonable basis for assum-
    ing that [the petitioner’s] lack of information about still
    more witnesses meant that there were none to be found.
    . . . With every effort to view the facts as a defense
    lawyer would have [viewed them] at the time, it is diffi-
    cult to see how [defense counsel] could have failed
    to realize that without seeking information that could
    either corroborate the alibi or contextualize it for the
    jury, he was seriously compromis[ing] [his] opportunity
    to present an alibi defense.’’ [Citations omitted; internal
    quotation marks omitted.]).
    Of course, ‘‘the duty to investigate does not force
    defense lawyers to scour the globe on the off chance
    something will turn up; reasonably diligent counsel may
    draw a line when they have good reason to think further
    investigation would be a waste.’’ Rompilla v. Beard,
    
    supra,
     
    545 U.S. 383
    . In other words, counsel is not
    required to conduct an investigation that ‘‘promise[s]
    less than looking for a needle in a haystack, when a
    lawyer truly has reason to doubt there is any needle
    there.’’ Id., 389. But ‘‘[p]retrial investigation and prepa-

    sel’’; (internal quotation marks omitted) Daniels v.

    record that there was any reason not to put [the witness]
    on the stand, and an attorney’s failure to present avail-
    able exculpatory evidence is ordinarily deficient, unless
    some cogent tactical or other consideration justified it.
    . . . And, second, [defense counsel’s failure to put her]
    on the stand was based on an inadequate investigation.
    . . . [Defense counsel] never contacted [the witness]
    with regard to her putative testimony, and never
    inquired into whether she might be willing to testify on
    [the petitioner’s] behalf. . . . [In cases in which a criti-
    cal issue is the relative credibility of the party’s wit-
    nesses], it should be perfectly obvious that it will almost
    always be useful for defense counsel to speak before
    trial with [readily available] fact witnesses whose non-
    cumulative testimony would directly corroborate the
    defense’s theory of important disputes. Accordingly,
    when [defense counsel] learned before trial that [she]
    might well be such a witness, he should have taken
    affirmative steps to discuss the case with her. . . . But
    [defense counsel] . . . did not contact [the witness].
    Indeed, there is no indication in the record that [coun-
    sel] conducted any substantial, affirmative investiga-
    tion into [the witness’] potential testimony.’’ [Citations
    omitted; emphasis in original; footnotes omitted; inter-
    nal quotation marks omitted.]).
    Similarly, a decision by counsel to forgo an investiga-
    tion into the possible testimony of a potentially signifi-
    cant witness is constitutionally unacceptable unless
    counsel has a sound justification for doing so; specula-
    tion, guesswork or uninformed assumptions about the
    availability or import of that testimony will not suffice.
    Instead, counsel must seek to interview the witness—
    or have the witness interviewed—to determine the
    value of any testimony that he may be able to provide.
    See, e.g., Ramonez v. Berghuis, 
    supra,
     
    490 F.3d 489
    (‘‘[c]onstitutionally effective counsel must develop trial
    strategy in the true sense—not what bears a false label
    of ‘strategy’—based on what investigation reveals wit-
    nesses will actually testify to, not based on what counsel
    guesses they might say in the absence of a full investiga-
    tion’’); Pavel v. Hollins, 
    supra,
     
    261 F.3d 221
     (defense
    counsel never contacted potentially favorable witness
    because counsel was ‘‘confident as to what [that] wit-
    ness would say,’’ but ‘‘counsel’s anticipation [of that
    testimony] does not excuse the failure to find out’’
    [internal quotation marks omitted]); United States v.
    Moore,

    anticipation of what a potential witness would say does
    not excuse the failure to find out; speculation cannot
    substitute for certainty’’).8 In the same vein, when coun-
    sel’s failure to proceed with an investigation is due
    not to professional or strategic judgment but, instead,
    results from oversight, inattention or lack of thorough-
    ness and preparation, no deference or presumption of
    reasonableness is warranted. See, e.g., Carter v. Dun-
    can, 
    819 F.3d 931
    , 942 (7th Cir. 2016) (‘‘[t]he conse-
    quences of inattention rather than reasoned strategic
    decisions are not entitled to the presumption of reason-
    ableness’’ [internal quotation marks omitted]); Wilson
    v. Mazzuca, 
    570 F.3d 490
    , 502 (2d Cir. 2009) (errors
    warranting determination of sixth amendment violation
    include ‘‘omissions [that] cannot be explained convinc-
    ingly as resulting from a sound trial strategy, but [rather,
    that] arose from oversight, carelessness, ineptitude, or
    laziness’’ [internal quotation marks omitted]).
    As I previously indicated, in determining whether
    counsel’s pretrial investigation satisfied existing profes-
    sional norms, we consider the nature and extent of
    the investigation in light of all relevant circumstances.
    Strickland v. Washington, 
    supra,
     
    466 U.S. 691
    . One such
    consideration is whether defense counsel undertook
    any investigation with respect to the particular witness
    involved, and, if so, at what point and for what reason
    did counsel decide to forgo any further investigation.
    A complete failure to take even the most elementary
    investigative steps with respect to a potential defense
    or witness is frequently deemed to be constitutionally
    inadequate. See, e.g., Bond v. Beard, 
    539 F.3d 256
    , 289
    (3d Cir. 2008), cert. denied, 
    558 U.S. 835

    ,
    
    130 S. Ct. 58
    , 
    175 L. Ed. 2d 232
     (2009); Ramonez v.
    Berghuis, 
    supra,

    , 473–74 (5th
    Cir.), amended in part on other grounds, 
    391 F.3d 703
    (5th Cir. 2004).
    Finally, with specific regard to the duty to investigate
    a defendant’s alibi defense, counsel is obligated to make
    all reasonable efforts to identify and interview potential
    alibi witnesses. See, e.g., Towns v. Smith, supra, 
    395 F.3d 259
     (‘‘Without even attempting to interview [the
    witness], counsel simply decided not to call him as a
    witness. That decision was objectively unreasonable
    because it was a decision made without undertaking a
    full investigation into whether [the witness] could assist
    in [the petitioner’s] defense. . . . By failing even to
    contact [the witness] . . . counsel abandoned his
    investigation at an unreasonable juncture, making a
    fully informed decision with respect to [whether to
    have the witness testify] impossible.’’ [Citation omitted;
    internal quotation marks omitted.]); Bryant v. Scott, 
    28 F.3d 1411
    , 1415 (5th Cir. 1994) (‘‘[A]n attorney must
    engage in a reasonable amount of pretrial investigation
    and at a minimum . . . interview potential witnesses
    and . . . make an independent investigation of the
    facts and circumstances in the case. . . . [W]hen alibi
    witnesses are involved, it is unreasonable for counsel
    not to try to contact the witnesses and ascertain
    whether their testimony would aid the defense.’’ [Cita-
    tions omitted; internal quotation marks omitted.]).
    Furthermore, the failure to conduct a thorough inves-
    tigation of an alibi defense is perhaps most damaging
    when ‘‘the missing witness is disinterested in a case in
    which the other witnesses have a relationship to the
    defendant.’’ Carter v. Duncan, supra, 
    819 F.3d 943
    ; see
    also Blackmon v. Williams, supra, 
    823 F.3d 1104
    –1105
    (explaining that unreasonableness of counsel’s failure
    to investigate was compounded by ‘‘significant potential
    benefits of obtaining alibi testimony from witnesses
    unimpaired by family ties to [the petitioner]’’); Mont-
    gomery v. Petersen, 
    846 F.2d 407
    , 413 (7th Cir. 1988)
    (characterizing disinterested alibi witness who defense
    counsel unreasonably failed to identify and locate as
    ‘‘extraordinarily significant’’ when all twelve alibi wit-
    nesses were either relatives or close friends of peti-
    tioner).
    In light of these general principles, it is readily appar-
    ent that Sherman’s decision to disregard Dowdle’s
    grand jury testimony about her ‘‘beau’’—a decision
    based solely on Sherman’s belief that any inquiry into
    that subject matter would not have been fruitful—was
    profoundly unreasonable under the circumstances. As
    a result, Sherman failed by a wide margin to satisfy
    Strickland’s requirement that a decision to forgo or
    truncate a particular pretrial investigation must flow
    from an informed professional judgment.
    Accordingly, the habeas court properly reached the
    only conclusion that the facts and law support: Sherman
    could not reasonably have elected simply to ignore
    Dowdle’s grand jury testimony and do nothing to con-
    tact her former ‘‘beau,’’ because all of the other alibi
    witnesses were close relatives of the petitioner, and
    Sherman knew both that the state would argue that
    those witnesses were all lying to protect the petitioner
    and that an independent alibi witness, with no ties to
    the petitioner or his family, would have enhanced the
    credibility of the petitioner’s alibi immeasurably.
    C
    The Flaws in the Majority’s Conclusion That the Habeas
    Court Incorrectly Concluded That Sherman
    Rendered Ineffective Assistance in
    His Handling of the Petitioner’s
    Alibi Defense
    The habeas court’s memorandum of decision is metic-
    ulous and thoughtful, and that court’s conclusion is fully
    supported by the facts and the law governing claims
    alleging ineffective assistance of counsel. Unfortunately
    for the petitioner—and, more generally, for the interests
    of justice—the same cannot be said of the majority
    opinion.
    The majority identifies four reasons for rejecting the
    habeas court’s conclusion that Sherman’s handling of
    the petitioner’s alibi defense did not satisfy constitu-
    tional standards. First, the majority asserts that Sher-
    man reasonably could have believed that, despite
    Dowdle’s testimony to the contrary, her unnamed
    ‘‘beau’’ was not, in fact, at the Terrien home on the
    evening of October 30, 1975, because neither the peti-
    tioner nor any of his alibi witnesses had told Sherman
    about the presence of Dowdle’s ‘‘beau’’ at the Terrien
    home that evening. The majority next claims that it was
    not unreasonable for Sherman either to have ‘‘over-
    look[ed] or disregard[ed]’’ Dowdle’s testimony about
    her ‘‘beau’’ because there was no reference to any such
    person in any of the interview reports and other materi-
    als that had been turned over to Sherman in discovery,
    and Dowdle’s reference to her ‘‘beau’’ was therefore
    aberrational. Third, even if Dowdle’s ‘‘beau’’ was at
    the Terrien home that evening, it was reasonable for
    Sherman to infer that, like Dowdle herself, he more or
    less stayed in the library, where he, Dowdle and her
    child were located, and, consequently, it also was rea-
    sonable for Sherman to assume that the ‘‘beau’’ did not
    go into the nearby room where the Skakel brothers and
    Terrien were watching television. Finally, the majority
    contends that, more than twenty years later, it was
    not unreasonable for Sherman to think that Dowdle’s
    ‘‘beau,’’ having never been interviewed or otherwise
    having come forward, likely would not have a reliable
    memory of the events of the evening of October 30, 1975.
    The majority asserts that, because these considerations
    provided Sherman with legitimate reasons to think that
    Dowdle’s ‘‘beau’’ would not be able to provide helpful
    alibi testimony, Sherman’s decision to take no action
    of any kind to identify the ‘‘beau’’ also was reasonable.
    As I explain hereinafter, these considerations fall far
    short of justifying Sherman’s failure to take even the
    most preliminary investigative steps to ascertain
    whether Dowdle’s ‘‘beau’’ could offer valuable alibi evi-
    dence. But, before doing do, I first explain the majority’s
    use of an improper standard to determine whether Sher-
    man was constitutionally required to make a reasonable
    inquiry into what, if anything, Dowdle’s ‘‘beau’’ knew
    about the petitioner’s whereabouts on the evening of
    October 30, 1975. I then discuss the multiple, compelling
    reasons why no competent attorney would have failed
    to conduct such an obvious and simple investigation
    in the present case. Thereafter, I return to the four
    reasons on which the majority relies to support its con-
    clusion that Sherman acted reasonably in doing nothing
    to follow up on Dowdle’s testimony about her ‘‘beau.’’
    1
    The Majority Employs the Wrong Legal Standard
    The standard that the majority uses for determining
    whether Sherman performed competently in declining
    to act on Dowdle’s grand jury testimony concerning
    her ‘‘beau’’ is whether Sherman reasonably could have
    concluded that such an investigation more than likely
    would not result in the discovery of any favorable testi-
    mony. According to the majority, under Strickland,
    Sherman had no constitutional duty to try to learn any-
    thing at all about Dowdle’s ‘‘beau’’ because Sherman
    reasonably believed, in light of all the relevant circum-
    stances, that her ‘‘beau’’ probably would not be able to
    provide any useful alibi testimony. On first reading, this
    reasoning might seem persuasive because it arguably
    was reasonable for Sherman to think that there was a
    better than even chance that Dowdle’s ‘‘beau’’ either
    would not be available to testify, or that he did not see
    the petitioner at the Terrien home on the evening of
    October 30, 1975, or that he could not recall the relevant
    events of that evening. The majority’s test, however, is
    patently unsupportable because whether Sherman had
    a duty to investigate Ossorio’s potential value as an
    alibi witness does not depend on whether Sherman
    reasonably may have believed or inferred that Ossorio
    more likely than not had no useful information. The
    proper standard, rather, is whether, under all the cir-
    cumstances, a competent attorney would have under-
    taken reasonable efforts to determine whether Ossorio
    had any such information. It is perfectly clear that, by
    doing absolutely nothing to ascertain Ossorio’s poten-
    tial value as an alibi witness, Sherman failed woefully
    to meet that standard.
    Accordingly, even if the reasons proffered by the
    majority support a reasonable inference that Ossorio
    might well not have been able to assist the petitioner’s
    defense, that inference would not remotely justify Sher-
    man’s failure to ascertain Ossorio’s identity from Dow-
    dle and to learn, from Ossorio himself, whether he saw
    the petitioner at the Terrien residence on the evening of
    October 30, 1975. As long as the facts and circumstances
    known to Sherman gave rise to a reasonable possibility
    that Ossorio might be able to provide valuable testi-
    mony, Sherman inarguably had an obligation to make
    a reasonable effort to find Ossorio and to ask him. As
    I explain hereinafter, those facts and circumstances
    leave no doubt that Sherman violated the petitioner’s
    constitutionally protected right to counsel by not mak-
    ing such an effort.
    The reasonable inference or belief standard that the
    majority adopts has no legal precedent and is entirely
    inadequate to protect the sixth amendment rights of an
    accused. Under that standard, a defense attorney would
    be free to refuse to initiate a reasonable investigation
    into the possible testimony of a potentially important
    witness, even in cases in which there remains a reason-
    able prospect that the witness will be able to provide
    vital defense evidence. Indeed, under the majority’s
    standard, defense counsel could abdicate any duty to
    investigate eyewitness testimony whenever conditions
    render it reasonably likely that the witness’ ability to
    observe or recall could have been impaired—for exam-
    ple, due to darkness, the consumption of alcohol, or
    the like. That simply cannot be the standard contem-
    plated by the sixth amendment, as it would give defense
    attorneys far too much leeway to decline to investigate
    potential witnesses when there is still a reasonable
    chance that the witness will be able to provide valuable
    testimony. Due to the significance of the pretrial investi-
    gation stage of a criminal case, the right to the effective
    assistance of counsel must include the right to have
    counsel conduct a reasonable investigation into any
    potentially important witness unless defense counsel
    can rule out any reasonable likelihood that the witness
    may be able to provide favorable testimony. That stan-
    dard, in stark contrast to the majority’s approach,
    affords criminal defendants an appropriate level of pro-
    tection because, under that test, defense counsel must
    take reasonable steps to follow leads for which there
    is a real and legitimate possibility that the investigation
    will yield favorable results, yet, at the same time, coun-
    sel permissibly may decide against initiating or continu-
    ing an investigation when doing so would simply be a
    waste of time; see Rompilla v. Beard, supra, 
    545 U.S. 383
    ; tantamount to a ‘‘scavenger hunt for potentially
    exculpatory information with no detailed instruction
    on what this information may be or where it might be
    found’’; United States v. Farr, 
    297 F.3d 651
    , 658 (7th
    Cir. 2002); or otherwise ‘‘pointless’’; United States v.
    Weaver, 
    882 F.2d 1128
    , 1138 (7th Cir.), cert. denied sub
    nom. Schmanke v. United States, 
    493 U.S. 968
    , 
    110 S. Ct. 415
    , 
    107 L. Ed. 2d 380
     (1989); ‘‘futile’’; United States
    v. Six, 
    600 Fed. Appx. 346
    , 350 (6th Cir. 2015); or ‘‘harm-
    ful to the defense.’’ Harrington v. Richter, 
    562 U.S. 86
    ,
    108, 
    131 S. Ct. 770
    , 
    178 L. Ed. 2d 624
     (2011).
    The sixth amendment does not mandate perfect coun-
    sel, of course, but it does require more of counsel during
    the pretrial investigation stage of the case than merely
    picking the lowest hanging fruit. Consequently, even if
    the reasons proffered by the majority justified the belief
    that Ossorio more than likely would not have been able
    to provide evidence favorable to the petitioner, that
    inference does not justify Sherman’s failure to make
    reasonable efforts to find out whether Ossorio was in
    a position to do so. This is hardly a case in which
    additional investigation would have been an exercise
    in futility or a waste of time. On the contrary, this is a
    case ‘‘in which the [petitioner’s] attorneys failed to act
    while potentially powerful mitigating evidence was star-
    ing them in the face . . . .’’ (Citations omitted.) Bobby
    v. Van Hook, 
    558 U.S. 4
    , 11, 
    130 S. Ct. 13
    , 
    175 L. Ed. 2d 255
     (2009). When, as in the present case, a defendant
    is being tried for murder and defense counsel knows
    of a potential witness who may be able to provide testi-
    mony critical to the defendant’s primary defense, coun-
    sel may not rely on inferences, beliefs or deductions in
    deciding to forgo even the most rudimentary investiga-
    tion into whether that witness can corroborate that
    defense.
    2
    Under the Proper Standard, Why There Are Compelling
    Reasons Why Sherman Was Required To Make
    Reasonable Efforts To Locate Ossorio
    The reasonableness of Sherman’s decision not to
    investigate whether Dowdle’s ‘‘beau’’ could provide tes-
    timony favorable to the petitioner turns on the facts of
    the case and the circumstances pertaining to the wit-
    ness. As I previously indicated, there are several com-
    pelling reasons why it was absolutely necessary for
    Sherman to have made reasonable efforts to find out
    whether Ossorio could corroborate the petitioner’s
    alibi, all of which the majority ignores. These reasons
    include (1) the firsthand nature of the source of the
    information to be investigated, (2) the importance of
    the petitioner’s alibi defense, (3) the significance of
    Ossorio’s testimony to that defense, (4) the import of
    Ossorio’s testimony to rebut the state’s claim of a long-
    standing family cover-up, (5) the ease with which Sher-
    man could have discovered that Ossorio clearly remem-
    bered that the petitioner was at the Terrien home on
    the evening at issue, and (6) the gravity of the criminal
    charges and the magnitude of the sentence that the
    petitioner faced. In light of these considerations, it was
    inexcusable for Sherman to do nothing to ascertain
    Ossorio’s identity, locate him, and then, upon doing so,
    either rule him out as an alibi witness or secure his
    testimony for trial if, as it has now been established,
    he could credibly corroborate that alibi.
    Before I address these considerations, it bears
    emphasis that the habeas court reviewed them, along
    with the reasons proffered by the respondent, the Com-
    missioner of Correction, for concluding that Sherman
    was not unreasonable in failing to follow up on Dow-
    dle’s grand jury testimony, and found, quite properly,
    that they outweigh the countervailing factors advanced
    by the respondent. Inexplicably, however, the majority
    does not even mention the considerations on which the
    habeas court and the petitioner relied; nor does the
    majority explain why they are not substantially more
    weighty and consequential than Sherman’s belief that
    there probably was no point in even trying to determine
    whether Dowdle’s ‘‘beau’’ would be able to corroborate
    the petitioner’s alibi defense. The court in Strickland
    made clear that, if counsel elects not to undertake a
    particular investigation, that decision itself must be rea-
    sonable under all of the circumstances. Strickland v.
    Washington, 
    supra,
     
    466 U.S. 691
    . As I discuss herein-
    after, the reasons that the majority proffers to justify
    Sherman’s decision not to follow up on Dowdle’s testi-
    mony are mere makeweights—indeed, they smack of
    the same kind of after the fact rationalization of coun-
    sel’s conduct that the United States Supreme Court
    rejected in Wiggins v. Smith, supra, 
    539 U.S. 526
    –27—
    and pale by comparison to the following, truly compel-
    ling considerations that support the petitioner’s con-
    tention that Sherman’s failure to take any action in
    regard to Ossorio violated the petitioner’s sixth amend-
    ment right to counsel.
    The first such consideration is the firsthand nature
    of the information provided by Dowdle in her grand
    jury testimony. Although Dowdle gave no indication
    one way or the other in that testimony whether Ossorio
    knew of the petitioner’s presence at the Terrien home
    on the evening of October 30, 1975, Dowdle did have
    direct knowledge that another identifiable and presum-
    ably independent person, Ossorio, was there that eve-
    ning. Thus, Dowdle’s information about Ossorio’s pres-
    ence was not based on hearsay or speculation; she had
    personal knowledge that Ossorio was at the Terrien
    home that evening.
    Second, the petitioner’s alibi was his primary defense
    to the state’s case against him. Although the state con-
    tended that it was possible that the victim was murdered
    as late as 1 a.m. on October 31, 1975, the substantial
    weight of the evidence indicated that the murder most
    likely was committed between 9:30 and 10 p.m. on Octo-
    ber 30. Consequently, because the state was required
    to disprove the petitioner’s alibi beyond a reasonable
    doubt; see, e.g., State v. Butler, 
    207 Conn. 619
    , 631, 
    543 A.2d 270
     (1988) (defendant in criminal case is entitled
    to instruction that state must rebut alibi defense beyond
    reasonable doubt); if the jury believed the petitioner’s
    alibi witnesses—indeed, even if the petitioner’s wit-
    nesses merely raised a reasonable doubt in the jurors’
    minds as to the petitioner’s whereabouts between 9:30
    and 10 p.m.—there is a very good likelihood that the
    petitioner would have been acquitted. See footnote 7
    of this opinion.
    The importance of the petitioner’s alibi defense is
    also reflected in how vigorously the state opposed it.
    State’s Attorney Benedict claimed that it had been con-
    cocted by the Skakel family and founded on the perjuri-
    ous testimony of the petitioner’s alibi witnesses. Ben-
    edict spent a considerable amount of time, both in
    adducing testimony from the state’s witnesses and in
    cross-examining the petitioner’s witnesses, as well as
    during closing argument, attempting to demonstrate
    that the petitioner’s alibi had been fabricated. It is likely
    that Benedict challenged the petitioner’s alibi so aggres-
    sively because, as the Supreme Court of New Jersey
    has observed, ‘‘few defenses have greater potential for
    creating reasonable doubt as to a defendant’s guilt in the
    minds of [the jurors than an alibi].’’ (Internal quotation
    marks omitted.) State v. Porter, 
    216 N.J. 343
    , 353, 
    80 A.3d 732
     (2013).
    Next, the testimony that Ossorio could have provided
    was unquestionably essential to the petitioner’s alibi
    defense. That testimony, which the habeas court
    expressly credited, placed the petitioner at the Terrien
    residence during the relevant time frame on the evening
    of October 30, 1975, thereby fully corroborating the
    testimony of the petitioner’s other alibi witnesses. But
    Ossorio’s testimony, while corroborative, certainly was
    not cumulative, because the petitioner’s other alibi wit-
    nesses were either siblings or cousins of the petitioner.
    Although Ossorio was friendly with Dowdle in the mid-
    1970s, there is no indication that he had maintained
    any ties to her or the Skakel family over the years, and,
    thus, he would have been an independent and unbiased
    witness with no motive to lie about seeing the petitioner
    at the Terrien home on the evening of October 30. Bene-
    dict emphatically and persistently maintained that the
    jury should not credit the petitioner’s alibi because all of
    the alibi witnesses were closely related to the petitioner
    and were lying to protect him. In light of this contention
    by the state, credible testimony from Ossorio would
    have been absolutely critical, both to establish the credi-
    bility of the alibi generally and to demonstrate the credi-
    bility of the petitioner’s witnesses more specifically.
    Indeed, if believed, Ossorio’s testimony would have dis-
    proved Benedict’s contention that the Skakel family
    had created the fictitious alibi to protect the petitioner
    and then continually lied, under oath and otherwise, in
    furtherance of the fraudulent scheme. Thus, with
    respect to the petitioner’s alibi defense, the quantum of
    evidence already known to Sherman—evidence marked
    by the weakness inherent in any alibi defense comprised
    solely of the testimony of family members—should have
    prompted Sherman to investigate the lead provided by
    Dowdle. See, e.g., Wiggins v. Smith, supra, 
    539 U.S. 527
     (‘‘[i]n assessing the reasonableness of an attorney’s
    investigation . . . a court must consider not only the
    quantum of evidence already known to counsel, but also
    whether the known evidence would lead a reasonable
    attorney to investigate further’’).
    In addition, as I discussed previously, the state
    adduced testimony from Ix, Shakespeare, and Julie Ska-
    kel in an effort to discredit the petitioner’s alibi defense.
    Testimony from a neutral, objective and credible wit-
    ness like Ossorio would have gutted the testimony of
    those state witnesses, testimony that no doubt appeared
    far more significant in light of the state’s contention
    that the petitioner’s alibi witnesses all were lying. In
    fact, it seems clear that the jury was influenced by the
    testimony of Ix, Shakespeare and Julie Skakel because
    the jury, during its deliberations, asked that the testi-
    mony of those witnesses, insofar as it related to the
    petitioner’s alibi, be read back.
    Along the same lines, Ossorio’s testimony also would
    have refuted Benedict’s claim that the alibi was an inte-
    gral part of a broader Skakel family scheme to cover
    up for the petitioner. According to Benedict, this
    scheme was hatched immediately after the victim’s mur-
    der and began with the disposal of incriminating evi-
    dence and the trip to Windham, New York, continued
    with the petitioner’s enrollment at the Elan School in
    Maine, and, thereafter, was exemplified by his allegedly
    self-serving statements to Richard Hoffman, the ghost-
    writer assisting the petitioner with his book, and, finally,
    culminated in the perjurious grand jury and trial testi-
    mony of the petitioner’s alibi witnesses. Because the
    allegedly fraudulent alibi provided the foundation for
    Benedict’s claim of a grand family scheme, Ossorio’s
    credible testimony demonstrating the validity of the
    alibi also would have debunked Benedict’s broader con-
    spiracy theory.
    Yet another consideration that the majority fails to
    consider is the ease with which Sherman could have
    ascertained that Ossorio had critical alibi testimony to
    offer, such that even the most rudimentary of inquiries
    would have led Sherman directly and immediately to
    Ossorio. See, e.g., Rompilla v. Beard, supra, 
    545 U.S. 389
    –90 (explaining that ‘‘[t]he unreasonableness of
    attempting no more than [counsel] did was heightened
    by the easy availability of the [material evidence]’’).
    Upon reading Dowdle’s grand jury testimony and learn-
    ing that her ‘‘beau’’ was with her at the Terrien residence
    on the evening of October 30, 1975, all Sherman had to
    do was pick up the telephone and ask Dowdle—his
    own alibi witness—to identify her ‘‘beau.’’ And then,
    after learning that her ‘‘beau’’ was Ossorio, it would
    have been easy for Sherman to locate and speak to
    him—indeed, a look in the telephone listings and
    another telephone call would have sufficed—because
    he lived just a few miles from Sherman’s office. As
    in all criminal cases that involve the issue of defense
    counsel’s failure to interview a potential witness to
    ascertain what he or she has to say, counsel has no
    absolute obligation ‘‘to actually track down’’ the wit-
    ness, ‘‘only that he put in a reasonable effort to do so.’’
    Avery v. Prelesnik, 
    548 F.3d 434
    , 438 (6th Cir. 2008),
    cert. denied, 
    558 U.S. 932
    , 
    130 S. Ct. 80
    , 
    175 L. Ed. 2d 234
     (2009); see also 
    id.
     (‘‘There is no reason based on
    professional judgment why [defense counsel] would not
    have pursued speaking to [the potential alibi witness].
    The [D]istrict [C]ourt correctly concluded that [defense
    counsel] was under a duty to reasonably investigate,
    which entails, at the bare minimum, asking for [the
    potential alibi witness’ telephone] number or address
    and reasonably attempting to contact him.’’ [Internal
    quotation marks omitted.]). In the present case, the
    most elementary and obvious of inquiries by Sherman
    or his investigator would have revealed that Ossorio
    was a critical alibi witness, and Sherman’s unwilling-
    ness to take even those modest steps unreasonably
    deprived the petitioner of Ossorio’s crucial trial tes-
    timony.
    Consequently, this is not a case that required Sher-
    man to devise a plan ‘‘to balance limited resources
    in accord with effective trial tactics and strategies.’’
    Harrington v. Richter, 
    supra,
     
    562 U.S. 89
    ; see also Rog-
    ers v. Zant, 
    13 F.3d 384
    , 387 (11th Cir.) (‘‘[the] correct
    approach toward investigation reflects the reality that
    lawyers do not enjoy the benefit of endless time, energy
    or financial resources’’), cert. denied, 
    513 U.S. 899
    , 
    115 S. Ct. 255
    , 
    130 L. Ed. 2d 175
     (1994). Taking his investiga-
    tion into Ossorio’s identity, whereabouts and possible
    testimony one step at a time, Sherman would have been
    able to successfully complete the investigation in two
    easy steps and at negligible expense. But, even if that
    were not so painfully apparent, the petitioner paid Sher-
    man more than $2 million in legal fees, and so the cost
    of undertaking reasonable steps to locate Ossorio, a
    potentially critical witness, certainly was not an issue.
    Finally, as a general matter, an adequate pretrial
    investigation is required in all criminal cases. But com-
    mon sense dictates that, when the stakes are highest—
    when the criminal charges are most serious, exposing
    the defendant to the most lengthy of prison terms—the
    importance of a thorough pretrial investigation is that
    much greater. In the present case, both the gravity of
    the charged offense, murder, and the magnitude of the
    potential maximum sentence, life imprisonment, are
    obvious. In such circumstances, the responsibilities of
    defense counsel are especially great, commensurate
    with the heightened exposure, concerns and expecta-
    tions of the defendant. Defense counsel must be particu-
    larly attentive to detail, because the defendant’s life is
    on the line. Of course, the gravity of the murder charge
    placed Sherman on notice that he needed to put appro-
    priate time, thought and effort into the case. He clearly
    did not live up to professional norms, however, in failing
    even to contact Dowdle after reading her grand jury
    testimony and learning that her ‘‘beau’’ was at the Ter-
    rien home, with her, on the evening of October 30, 1975.
    3
    The Majority Cannot Justify Sherman’s
    Grossly Inadequate Handling of the
    Petitioner’s Alibi Defense
    The majority goes to great lengths in trying to ratio-
    nalize Sherman’s indefensible failure to follow up on
    Dowdle’s grand jury testimony, which identified her
    ‘‘beau’’ as a potential, independent alibi witness. The
    majority’s attempt to justify Sherman’s decision to forgo
    even the most rudimentary and self-evident steps to
    find out if Ossorio could corroborate the petitioner’s
    alibi—steps that, if taken, would have put Sherman
    in touch with Ossorio immediately—is both unavailing
    and troubling.
    The majority first argues that it was reasonable for
    Sherman to believe, in spite of Dowdle’s testimony to
    the contrary, that her unnamed ‘‘beau’’ actually was not
    present with her at the Terrien residence on the evening
    of October 30, 1975, because neither the petitioner nor
    his alibi witnesses had mentioned anything to Sherman
    about Dowdle’s ‘‘beau.’’ Even if this argument was pred-
    icated on an accurate rendition of the facts,9 it is based
    on a fundamental misunderstanding of the timeline of
    this case.
    It is undisputed that the petitioner was never consid-
    ered a suspect in the victim’s murder before the mid-
    1990s; rather, he was considered only a potential wit-
    ness before that time. Indeed, State’s Attorney Benedict
    acknowledged this fact at trial, noting that, until the
    1990s, no witness had ever been asked to account for
    the petitioner’s whereabouts or movements on the night
    of the murder because the police never suspected his
    involvement in the crime. Two events occurred in the
    1990s that caused the petitioner to fall under suspicion:
    the theft of the Sutton files, in 1995, which revealed
    that the petitioner had changed his account of his activi-
    ties on the night of the murder, and the publication of
    a book by Mark Fuhrman, in 1998, in which Fuhrman
    claimed to have solved the long, unsolved murder by
    being the first to suspect the petitioner’s involvement
    in it. Fuhrman urged that a grand jury be empaneled
    immediately to investigate his theory. Shortly there-
    after, a grand jury was empaneled, and, in July, 1998,
    the petitioner hired Sherman to represent him in con-
    nection with that proceeding. Dowdle was called before
    the grand jury two months later, on September 22, 1998,
    at which time she was asked about her recollection of
    the evening of October 30, 1975. Dowdle explained that
    she was at home with her ‘‘beau.’’
    Accordingly, and contrary to the assertion of the
    majority, the existence of a potential, independent alibi
    witness for the petitioner was revealed as soon as the
    petitioner became a suspect in the murder, by the only
    person who was likely to recall after so many years
    that such a person even existed. Given the belated
    development of the case against the petitioner, Sherman
    should have known that it was possible—even likely—
    that neither the petitioner nor the other alibi witnesses
    recalled or had given any thought to whether Ossorio—
    or anyone else—was at the Terrien residence on the
    evening of October 30, 1975. It is apparent, for instance,
    that even Dowdle failed to appreciate the significance
    of Ossorio’s presence at her home, either when she
    testified before the grand jury or when she again men-
    tioned him at the petitioner’s criminal trial four years
    later. In any event, there are many reasonable explana-
    tions why the petitioner and his alibi witnesses did
    not volunteer information about Ossorio to Sherman
    immediately after he was retained by the petitioner, but
    there is simply no justification for Sherman to have
    concluded that Dowdle was mistaken about the pres-
    ence of her ‘‘beau’’ at the Terrien home, or, if her ‘‘beau’’
    was there with her, that he would not know whether
    the petitioner also was present at that time. The only
    rational thing for Sherman to do to clarify any confusion
    that he may have had about Dowdle’s testimony would
    have been to speak to her about the matter.10 This is
    especially true in view of the fact that, at the petitioner’s
    criminal trial, Dowdle again testified that she had a
    companion with her on the evening of October 30, 1975,
    this time characterizing him as a ‘‘friend.’’ Inexplicably,
    Sherman failed to follow up on either reference.
    The majority also contends that, despite Dowdle’s
    reference to her ‘‘beau’’ in her grand jury testimony,
    Sherman reasonably could have believed that Ossorio
    was not at the Terrien home on the evening of October
    30, 1975, because he had never been named in the many
    police reports that were generated after the murder.
    The majority asserts that the absence of Ossorio from
    these reports rendered Dowdle’s reference to him as
    aberrational and, therefore, somehow insignificant.
    This contention, too, is baseless, and for much the same
    reason. Because the petitioner did not become a suspect
    until more than twenty years after the murder, police
    investigators simply were not concerned about the peti-
    tioner’s whereabouts during the twenty year period in
    which the vast majority of the police interviews were
    conducted. Until the petitioner became a suspect, there
    was never any reason for the police to seek a complete
    accounting of all individuals present at the Terrien
    home on the evening of October 30, 1975. Thus, the
    majority is unable to cite a single report in which Osso-
    rio likely would have been identified in the course of
    the interview. In fact, there is no such report because,
    as Benedict expressly acknowledged at trial, until the
    1990s, witnesses had never been asked to account for
    the petitioner’s whereabouts on the night of the murder
    for the simple reason that no one who indicated being
    at the Terrien home on the evening of October 30,
    including the petitioner, ever was a suspect before that
    time. In other words, the majority’s suggestion that
    Dowdle’s reference to her ‘‘beau’’ is aberrational
    assumes without any evidentiary support that there was
    a context in which Ossorio’s name—or the name of
    anyone else who was visiting or working at the Terrien
    home on October 30—would have come up during the
    first twenty years of the investigation. The simple fact
    of the matter is that Ossorio’s name would have come
    up only if the police had suspected that the petitioner,
    Rushton Skakel, Jr., John Skakel, or Terrien did not go
    to the Terrien home as reported and, therefore, had
    asked them whether anyone could vouch for their pres-
    ence there.
    In this respect, the present case is governed by the
    principles announced in Rompilla v. Beard, supra, 
    545 U.S. 383
    , in which defense counsel was deemed to have
    rendered constitutionally deficient assistance by failing
    to review more thoroughly certain evidence in the pros-
    ecutor’s possession. In addressing the dissent’s primary
    argument, the court stated: ‘‘The dissent would ignore
    the opportunity to find this [mitigating] evidence on the
    ground that its discovery . . . rests on serendipity
    . . . . But once counsel had an obligation to examine
    the file, counsel had to make reasonable efforts to learn
    its contents; and once having done so, they could not
    reasonably have ignored mitigation or red flags simply
    because they were unexpected.’’ (Citation omitted;
    internal quotation marks omitted.) 
    Id.,
     391 n.8. That is
    precisely the situation in the present case: Sherman
    concededly had an obligation to review Dowdle’s grand
    jury testimony with reasonable care, and once having
    done so, he could not ignore the obvious red flag raised
    by that testimony, namely, that Dowdle was accompa-
    nied by her ‘‘beau’’ at the Terrien residence on the
    evening of October 30, 1975.11
    The majority next tries to convince us that it was
    reasonable for Sherman to infer that, because Dowdle
    indicated in her grand jury testimony that she mostly
    stayed in the library that evening and had not seen
    the Skakel brothers herself, Ossorio, too, did not have
    occasion to see who was watching television in an adja-
    cent room. This argument, too, is based on the unsup-
    ported assumption that Ossorio stayed put in the library
    all evening, even when Dowdle went to put her daughter
    to bed. The fact is that Sherman had no idea whether
    Ossorio remained in the library, wandered around the
    house, spent time in the television room or otherwise
    bumped into the Skakel family members during the
    ninety minutes or so that they were all together in the
    Terrien residence. Of course, the only way for Sherman
    to have found out is to have asked Ossorio, but, inexpli-
    cably, he made no effort to do so.
    The majority also asserts that Sherman reasonably
    could have believed that Ossorio likely would not be
    able to recall what occurred on the evening of October
    30, 1975, because Sherman could not have interviewed
    him until Sherman was retained in 1998, some twenty-
    three years after the relevant events. To buttress this
    argument, the majority observes that Ossorio had not
    been questioned or otherwise come forward in those
    twenty-three years, lending support to the inference
    that he would not be able to remember who was present
    at the Terrien home that evening. Again, although Osso-
    rio might not have remembered whether the petitioner
    was at the Terrien home on October 30, he well might
    have. And, indeed, he did. Sherman obviously could not
    rule out that possibility, and he made no effort to do
    so—if he had, he would have learned that Ossorio did,
    in fact, see the petitioner there that evening. Under the
    majority’s logic, Sherman had no duty to make any
    effort to follow up on any lead about any new or addi-
    tional alibi witness—or any kind of witness, for that
    matter—because he reasonably could have concluded
    that no such witness was likely to remember events
    from more than two decades beforehand. Of course,
    the case concerned events long in the past, and, so,
    both the state and the defense were required to do their
    best to develop facts based largely on memory and
    recall. Indeed, this case never could have been brought
    but for the state’s ability to locate witnesses who could
    remember and testify about events that had occurred
    decades earlier. Sherman’s job in defending the peti-
    tioner necessarily required him to undertake the same
    investigation. The majority, however, agrees with the
    respondent that it was reasonable for Sherman to forgo
    an investigation into Ossorio due to the lapse of time.
    This argument makes no sense to me, and I simply
    cannot see why the majority finds it persuasive.
    Finally, from my perspective, the majority’s attempt
    to rehabilitate Sherman’s representation of the peti-
    tioner misses the point altogether. As I discussed pre-
    viously, when a defense attorney represents a defendant
    in a murder case involving an alibi, the dictates of the
    sixth amendment—that the attorney take reasonable
    steps to advance that alibi—are coextensive with com-
    mon sense; after all, reasonableness and common sense
    are closely related. And it defies common sense to con-
    clude that it was perfectly reasonable for Sherman to
    decide that he need not even speak to Dowdle about
    her ‘‘beau’’ because he felt there was a likelihood that
    any such inquiry would prove to be unproductive. The
    fact is, of course, that there was absolutely no reason
    for Sherman even to attempt to evaluate the likelihood
    that Ossorio could or could not provide important alibi
    testimony; the only reasonable thing for Sherman to do
    was to ask Ossorio, which he readily could have done
    but elected not to do. That the majority defends Sher-
    man’s inexplicably poor and prejudicial decision mak-
    ing with respect to Ossorio, and concludes that it
    somehow comports with the petitioner’s right to the
    effective assistance of counsel, is indeed baffling.
    4
    The Majority’s Position Has No Support
    in Applicable Precedent
    In support of its argument that, under all the facts
    and circumstances, it was reasonable for Sherman to
    ‘‘overlook or disregard’’ Dowdle’s ‘‘singular reference’’
    to her ‘‘beau’’ in her grand jury testimony, the majority
    suggests that courts have not found counsel ineffective
    for failing to interview an alibi witness when the defen-
    dant did not bring that witness to the attention of coun-
    sel. The majority is entirely mistaken both in its ultimate
    conclusion and in its reading of the relevant case law.
    As the majority appears to concede, it is generally
    not reasonable for counsel to fail to investigate potential
    alibi witnesses identified by a client. See, e.g., Mosley
    v. Atchison, 
    689 F.3d 838
    , 849 (7th Cir. 2012); Grooms
    v. Solem, 
    923 F.2d 88
    , 90 (8th Cir. 1991); Vazquez v.
    Commissioner of Correction, 
    107 Conn. App. 181
    , 185–
    86, 
    944 A.2d 429
     (2008). By the same token, ‘‘[d]efense
    counsel is not required . . . to investigate everyone
    whose name happens to be mentioned by the defen-
    dant.’’ (Internal quotation marks omitted.) Nealy v.
    Cabana, 
    764 F.2d 1173
    , 1178 (5th Cir. 1985). The major-
    ity is manifestly incorrect, however, insofar as it
    appears to assert that counsel is not ineffective in failing
    to investigate an alibi witness unless the defendant
    provides counsel with the witness’ name. Contrary to
    the majority’s suggestion—and to common sense, as
    well—the key consideration is not whether the client
    has mentioned the witness to counsel but whether a
    reasonably diligent and effective lawyer, once apprised
    of the existence of a potentially critical witness, could
    make a ‘‘reasonable professional [judgment]’’ that it
    was nonetheless unnecessary to contact the witness
    or otherwise to pursue that line of defense. (Internal
    quotation marks omitted.) Wiggins v. Smith, supra, 
    539 U.S. 533
    . Of course, the answer to that question is ‘‘no.’’
    The majority cites Gaines v. Commissioner of Cor-
    rection, supra, 
    306 Conn. 664
    , in particular, for the prop-
    osition that counsel’s failure to investigate an alibi
    witness renders his performance deficient only when
    he has been provided with the witness’ identity and has
    ‘‘reason to believe that the witness might have helpful
    information to give.’’ Gaines stands for no such proposi-
    tion and cannot arguably be read as the majority does.
    In that case, the petitioner, Norman Gaines, was com-
    pletely unable to remember his whereabouts on the
    night of the crime or to remember a single witness
    who might attest to them. Gaines v. Commissioner of
    Correction, supra, 675. Nonetheless, this court found
    that his defense attorney’s representation was ineffec-
    tive insofar as he failed to interview either of the only
    two individuals that Gaines mentioned as people he
    knew in Bridgeport, where the crime occurred, even
    though Gaines never suggested that they might have
    information helpful to his defense. Id., 685–87.
    Gaines, therefore, hardly stands for the proposition
    that counsel need not investigate witnesses who have
    not been identified by the client. To the contrary,
    Gaines clearly illustrates why Sherman was manifestly
    ineffective insofar as he failed to look into Dowdle’s
    ‘‘beau.’’ First, in Gaines, we noted how easy it would
    have been to contact the potential witnesses. See id.,
    685–86 (‘‘no . . . extensive investigation, based wholly
    on conjecture, was necessary to discover or to contact
    [the witness]’’). In the present case, as I explained, it
    can hardly be said that contacting Ossorio would have
    been any more difficult.12 Second, in Gaines, we empha-
    sized that counsel was responsible for making a context
    specific assessment of the value of potential witnesses,
    completely apart from the assessment made by Gaines.
    See id., 684 (‘‘[Gaines’] failure to indicate explicitly that
    [the witness] possessed information that would be help-
    ful to his case did not relieve [counsel] of his duty to
    interview [the witness]. Criminal defendants are guar-
    anteed effective assistance of counsel, including ade-
    quate pretrial investigation, because they require the
    skill and knowledge of an individual trained in the
    adversarial process to identify the most important wit-
    nesses and evidence in order to present the most effec-
    tive defense.’’). In the present case, just as in Gaines,
    Sherman immediately should have recognized the
    potential value of Ossorio’s testimony, even though he
    was not identified by the petitioner. Indeed, the possibil-
    ity that a person identified as being at the scene in
    question would remember who else was there—like
    in the present case—is hardly more remote than the
    possibility, as in Gaines, that a person that Gaines knew,
    though not placed with him on the night of the crime,
    would in fact have been moving her belongings with
    Gaines on a particular night five months earlier, and
    would also happen to remember that fact. See id., 671,
    686–87. Furthermore, just as in Gaines, the fact that
    Ossorio might not have ended up providing useful infor-
    mation is entirely beside the point. Given the potential
    value of his testimony and the ease with which it might
    have been acquired, there is simply no justification—
    none whatsoever—for Sherman’s decision not to inves-
    tigate further.
    In fact, the majority’s unsupported contention to the
    contrary notwithstanding, courts have consistently rec-
    ognized that effective counsel cannot limit his investiga-
    tion to those leads presented by the client himself, but,
    rather, counsel has an independent duty to investigate
    potential alibi witnesses not suggested by the client. In
    Bigelow v. Haviland, 
    supra,
     
    576 F.3d 284
    , for instance,
    the Sixth Circuit held that counsel ‘‘had no reasonable
    basis for assuming that [the petitioner’s] lack of infor-
    mation about still more [alibi] witnesses [aside from
    one already identified by the petitioner] meant that
    there were none to be found.’’ 
    Id., 288
    . The court
    observed that an attorney has a duty of investigation
    that goes beyond what the client himself identifies and
    concluded that counsel’s representation was ineffective
    insofar as he failed to pursue such additional investiga-
    tion as would have revealed the alibi witnesses. 
    Id.,
    288–89. Federal case law is replete with such examples.
    See, e.g., Stitts v. Wilson, 
    713 F.3d 887
    , 893 (7th Cir.
    2013) (‘‘When a defendant’s alibi is that he was at a
    nightclub at the time of the shooting, where there are
    presumably many people, we cannot fathom a reason
    consistent with [United States] Supreme Court prece-
    dent that would justify a trial counsel’s decision to
    interview only a single alibi witness without exploring
    whether there might be others at the venue who could
    provide credible alibi testimony. There is simply no
    evidence in the record to suggest that exploring the
    possibility of other alibi witnesses ‘would have been
    fruitless’ under these circumstances.’’ [Emphasis omit-
    ted.]), cert. denied,      U.S.    ,

     (2014); United States v. Gray, 
    878 F.2d 702
    , 711–12 (3d Cir. 1989) (counsel was ineffective when
    he failed to interview unnamed potential eyewitnesses
    to altercation, in addition to several known witnesses);
    Sullivan v. Fairman, 
    819 F.2d 1382
    , 1391–92 (7th Cir.
    1987) (counsel was ineffective when he made merely
    ‘‘perfunctory’’ efforts to interview witnesses noted in
    police reports).
    The facts of this case illustrate the need for just such
    an independent duty. By the late 1990s, it is entirely
    unsurprising that the petitioner failed to recall the tran-
    sitory presence of his older cousin’s boyfriend nearly
    twenty-five years earlier. In such a situation, counsel
    must probe harder—to seek to fill in the gaps when
    the foibles of memory are likely to interfere with a
    defendant’s full recollection of the past. See Bigelow
    v. Haviland, 
    supra,
     
    576 F.3d 288
     (counsel’s duty to
    look beyond witnesses identified by client is especially
    significant when client may have trouble remembering
    them himself). Courts have reasonably recognized,
    moreover, that such duties grow increasingly acute as
    the gravity of the crimes charged increases. See Gaines
    v. Commissioner of Correction, supra, 
    306 Conn. 684
    (‘‘[g]iven the seriousness of the charges that his client
    faced [and the other relevant considerations], it was
    unreasonable for [defense counsel] not to recognize the
    potential that [the witness] might possess information
    helpful to the petitioner’s case’’); see also Gregg v. Rock-
    view, 
    596 Fed. Appx. 72
    , 77 (3d Cir. 2015) (‘‘[e]specially

    tigation into [another]’’); Raygoza v. Hulick, 
    474 F.3d 958
    , 964 (7th Cir.) (‘‘[i]n a [first degree] murder trial, it
    is almost impossible to see why a lawyer would not at
    least have investigated the alibi witnesses more thor-

    ment, counsel should have tried to investigate the
    potential alibi witnesses’’); Coleman v. Brown,

    , 1234 (10th Cir. 1986) (‘‘[i]n light of the strong

    charges, it was improper for his attorney to fail to inves-
    tigate what was perhaps [the petitioner’s] sole line of

     (1987).
    Thus, there is no question that Sherman’s perfor-
    mance was not rendered effective merely by virtue of
    any inability on the petitioner’s part to recollect the
    presence of Dowdle’s ‘‘beau.’’ If Sherman was aware
    of Ossorio’s presence and believed that his testimony
    might be useful, Sherman had an independent duty to
    investigate, regardless of whether the petitioner pointed
    him in that direction. The majority argues, nonetheless,
    that Sherman, having examined the grand jury testi-
    mony with reasonable care,13 could justifiably have
    declined to investigate the potential witness on the
    assumption that Ossorio would not have possessed use-
    ful information. Myriad cases point in the opposite
    direction.
    In fact, courts have often criticized attorneys who
    fail to investigate potential witnesses on the basis of
    flawed assumptions about their usefulness. See United
    States v. Best, 
    426 F.3d 937
    , 945 (7th Cir. 2005) (‘‘[a]n
    outright failure to investigate witnesses [as opposed to
    the decision not to call such witnesses after investiga-
    tion], is more likely to be a sign of deficient perfor-
    mance’’); Black v. Larson, 
    45 Fed. Appx. 653
    , 655 (9th
    Cir. 2002) (‘‘[a]lthough generally we defer to counsel’s
    decision not to proffer a witness at trial, that decision
    is entitled to less deference when the attorney fails to
    interview the witness’’); Gomez v. Beto, 
    462 F.2d 596
    ,
    597 (5th Cir. 1972) (counsel was ineffective for failing
    to investigate and subpoena alibi witnesses because,
    among other things, ‘‘he did not believe [that] a person
    could remember that long ago’’). In Blackmon v. Wil-
    liams, supra, 
    823 F.3d 1105
    , for instance, the Seventh
    Circuit concluded that counsel’s representation was
    ineffective insofar as he failed to investigate potential
    alibi witnesses who had attended a barbeque with the
    petitioner at a time relevant to the crime alleged. The
    Seventh Circuit roundly criticized the state court for
    ‘‘appear[ing] to assume that counsel knew, somehow,
    that the additional alibi witnesses would offer purely
    cumulative testimony.’’ Id., 1104. Rather, the court
    observed that, ‘‘[i]f counsel never learned what the wit-
    nesses would have said, he could not possibly have
    made a reasonable professional judgment that their tes-
    timony would have been cumulative.’’ (Internal quota-
    tion marks omitted.) Id.; see also Anderson v. Johnson,
    
    338 F.3d 382
    , 392–93 (5th Cir. 2003) (counsel was inef-
    fective for assuming, after reviewing state’s file but
    without further investigation, that witness would not
    provide useful testimony). Courts have been similarly
    critical of assumptions made about a witness’ ability
    or willingness to testify on behalf of the defendant.
    See Avila v. Galaza, 
    297 F.3d 911
    , 920 (9th Cir. 2002)
    (‘‘[Counsel] . . . failed to identify these potential wit-
    nesses because he thought that some of the people
    might not make the best appearance before a jury, and
    because his investigator . . . told him . . . that some
    witnesses had been uncooperative. That witnesses
    might not cooperate or make the best appearance at
    trial are unreasonable bases not to identify or attempt
    to interview them, however. A lawyer has a duty to
    investigate what information . . . potential [eyewit-
    nesses possess], even if he later decide[s] not to put
    them on the stand.’’ [Emphasis in original; internal quo-
    tation marks omitted.]), cert. dismissed, 
    538 U.S. 919
    ,
    
    123 S. Ct. 1571
    ,

     (2003); Schlup v.
    Bowersox, United States District Court, Docket No.
    4:92CV443 (JCH) (E.D. Mo. May 2, 1996) (‘‘The record
    lacks evidence supporting trial counsel’s assumption
    that interviewing eyewitnesses would have been fruit-
    less because no eyewitnesses would have discussed the
    murder . . . . In the absence of evidence supporting
    trial counsel’s assumption, his complete failure to inter-
    view eyewitnesses to the crime falls below an objective
    standard of reasonableness. Trial counsel did not have
    a sufficient basis for believing that investigating eyewit-
    nesses would not benefit the defense.’’).
    In the present case, it is readily apparent that the
    potential value of Ossorio’s testimony was far too high
    for Sherman to dismiss Dowdle’s reference—even a
    single reference—without reasonable investigative
    effort.14 As the Eighth Circuit has observed, ‘‘[o]nce
    a defendant identifies potential alibi witnesses, it is
    unreasonable not to make some effort to contact them
    to ascertain whether their testimony would aid the
    defense.’’ Grooms v. Solem, 
    supra,
     
    923 F.2d 90
    . In that
    case, counsel failed to investigate a potential alibi that
    arose at the beginning of trial on the assumption that
    he would be precluded from offering any alibi witnesses
    on state procedural grounds. See 
    id.
     In the present case,
    Sherman faced no such procedural barrier; he merely
    assumed, on the basis of the petitioner’s twenty-five
    year old recollection, that Ossorio would be able to offer
    no useful testimony. Such an assumption is patently
    unreasonable in the circumstances presented.
    In reaching a contrary conclusion, the majority relies
    on cases involving facts that bear no resemblance to
    the present case. It suggests, first, that, as in United
    States v. Farr, 
    supra,
     
    297 F.3d 658
    , Sherman did not
    act unreasonably in failing to engage in a ‘‘ ‘scavenger
    hunt’ ’’ for potentially exculpatory information with no
    reason for knowing what the information was or where
    it might be found. In Farr, however, the defendant had
    refused to cooperate with his attorney; see id., 654; and
    could not, on appeal, ‘‘name a single witness who could
    help his cause, much less identify the substance of their
    alleged testimony.’’ Id., 656. Thus, the court had no
    reason to decide whether the defendant’s counsel was
    ineffective; without any sense of who the witnesses
    were or what they might say in his defense, the court
    could conclude only that the defendant was not preju-
    diced by the missing testimony. Id., 659. In the present
    case, by contrast, the location and import of the poten-
    tially exculpatory information is—and always has
    been—beyond question. Sherman simply needed to
    speak to Dowdle and ask her who her ‘‘beau’’ was.
    The majority also refers to two Eighth Circuit cases
    to illustrate the significance of the petitioner’s failure
    to precisely identify Ossorio or to help Sherman locate
    him. But, once again, the majority fails to ascribe any
    value to identifiability, focusing narrowly on the for-
    mality of whether the defendant has fully identified the
    witness for the benefit of counsel. What these cases
    stand for, in fact, is the proposition that counsel is not
    required to conjure up a witness of uncertain value
    when that witness is not reasonably identifiable.15 In
    those cases, unlike in the present case, each witness
    was misidentified in the police reports—a barrier to
    investigation that, without the aid of the defendant,
    counsel had failed to surmount. See Battle v. Delo, 
    19 F.3d 1547
    , 1555 (8th Cir. 1994), amended on other
    grounds, 
    64 F.3d 347
     (8th Cir. 1995), cert. denied sub
    nom. Battle v. Bowersox, 
    517 U.S. 1235
    , 
    116 S. Ct. 1881
    ,
    
    135 L. Ed. 2d 176
     (1996). Furthermore, counsel in at
    least one of these cases, unlike Sherman, did make
    efforts to investigate the misidentified witness. See
    Harris v. Bowersox, 
    184 F.3d 744
    , 756–57 (8th Cir.
    1999), cert. denied, 
    528 U.S. 1097
    , 
    120 S. Ct. 840
    , 
    145 L. Ed. 2d 706
     (2000). In any event, both cases are inappo-
    site: in the present case, there was no impediment to
    investigation. Sherman, unlike counsel in Harris, sim-
    ply failed to try.16
    This failure to investigate, as I explained, was not
    the product of strategic thinking; it was the result of
    unfounded and unsupportable assumptions about the
    value of a potentially critical alibi witness in a murder
    case. However sparse the references to Ossorio, this is
    not a case in which counsel was at liberty to ignore them
    or to risk miscalculating their potential significance.
    Rather, it was his constitutional responsibility to take
    reasonable steps to ascertain Ossorio’s identity and to
    determine his value as a witness. Sherman knew that
    Ossorio was the only unrelated alibi witness; see Mont-
    gomery v. Petersen, 
    supra,
     
    846 F.2d 413
     (failure to inter-
    view only disinterested alibi witness was unreason-
    able); and he had no real basis, aside from conjecture,
    for concluding that Ossorio would not prove to be a
    useful witness. See, e.g., State v. Sanford, 
    24 Kan. App. 2d 518
    , 523, 
    948 P.2d 1135
     (failure to question potential
    witnesses was unreasonable when counsel merely
    ‘‘believed that they would be hostile witnesses’’), review
    denied, 
    262 Kan. 967
     (1997). Armed with the knowledge
    of a potentially critical breakthrough, it is inconceivable
    that a competent attorney would decline to make even
    perfunctory efforts to contact such a witness. In cases
    like these, courts have not hesitated to find that coun-
    sel’s assistance did not satisfy the requirements of the
    sixth amendment. Neither should we.
    D
    Conclusion
    When Sherman learned from Dowdle’s sworn grand
    jury testimony that another person, subsequently identi-
    fied as Ossorio, was present at the Terrien home on
    the evening of October 30, 1975, Sherman simply elected
    to disregard that testimony. He did so, even though he
    did not know whether Ossorio could corroborate the
    petitioner’s alibi and even though he could have found
    out in no time and with virtually no investigative effort
    that Ossorio could, indeed, provide critical alibi testi-
    mony. In not bothering to follow up on Dowdle’s testi-
    mony, Sherman disregarded his professional obligation
    to investigate critical prosecution evidence, thereby
    engendering ‘‘a breakdown in the adversarial process
    that our system counts on to produce just results.’’
    Strickland v. Washington, 
    supra,
     
    466 U.S. 696
    . It is
    nothing short of astonishing that the majority approves
    of Sherman’s game of Russian roulette, with the peti-
    tioner’s freedom at stake, as consonant with the consti-
    tutional guarantees of a fair trial and the effective
    assistance of counsel.
    II
    SHERMAN’S FAILURE TO RAISE A THIRD-PARTY
    CULPABILITY DEFENSE AGAINST
    THOMAS SKAKEL
    I also must register my strong objection to the majori-
    ty’s determination that the habeas court incorrectly con-
    cluded that Sherman’s representation was constitution-
    ally deficient insofar as he failed to pursue a third-party
    culpability defense17 against Thomas Skakel in light of
    Thomas Skakel’s highly incriminating admissions in
    Sherman’s presence and in the presence of Sherman’s
    associate, Throne, on the eve of the petitioner’s criminal
    trial. Eight days before that trial, Thomas Skakel admit-
    ted to Sherman and Throne that he had lied to the police
    in 1975 when he told them that the victim left his house
    at 9:30 p.m. Thomas Skakel admitted that, in fact, he
    and the victim had a sexual encounter in his backyard
    that lasted until at least 9:50 p.m., placing Thomas Ska-
    kel with the victim at the likely time of her death.
    Indeed, the victim was found with her pants and under-
    wear down around her knees, which is completely con-
    sistent with Thomas Skakel’s statement about his
    sexual contact with her.
    The majority concludes that Sherman’s decision to
    implicate Littleton rather than Thomas Skakel was
    objectively reasonable, but not because the evidence
    implicating Littleton was strong. It was not. In fact, it
    was nonexistent. The majority concludes, rather, that
    the evidence adduced at the habeas trial did not support
    the habeas court’s finding that Thomas Skakel dis-
    cussed his sexual encounter with the victim when he
    met with Sherman and Throne in 2002 and, therefore,
    that the evidence did not support the habeas court’s
    finding that Sherman could have called Throne to the
    stand to testify about Thomas Skakel’s admissions. The
    majority also concludes that the habeas court’s finding
    that Throne could have testified about the admissions
    was ‘‘entirely speculative’’ in light of Throne’s inability,
    at the petitioner’s 2013 habeas trial, to remember the
    specifics of what was discussed at the 2002 meeting,
    apart from the fact that Thomas Skakel admitted to
    having lied to the police about when he last saw the
    victim. The majority finally concludes that, even if
    Thomas Skakel discussed his sexual liaison with the
    victim with Throne and Sherman, and even if Throne
    would have recalled that discussion long enough to
    testify about what Thomas Skakel told them at the
    petitioner’s criminal trial one week later, Sherman’s
    decision not to pursue a third-party defense inculpating
    Thomas Skakel was objectively reasonable as a strate-
    gic matter. Specifically, the majority contends that
    apprising the jury that Thomas Skakel had changed his
    story after twenty years and admitted to having a sexual
    encounter with the victim minutes before her death ran
    the risk of strengthening the state’s theory regarding
    the petitioner’s motive for killing the victim. None of
    the majority’s conclusions withstands scrutiny.
    Before addressing each of the majority’s conclusions
    in turn, however, it is necessary to compare the evi-
    dence implicating Littleton with that which pointed to
    Thomas Skakel as the killer. The majority’s recitation
    of that evidence omits many essential facts that bear
    directly on the objective reasonableness of Sherman’s
    decision to raise a third-party culpability defense
    against one and not the other. When such a comparison
    is made, however, it is manifestly clear that Sherman’s
    decision to implicate Littleton was entirely unreason-
    able given the dearth of evidence connecting him to the
    murder and the multitude of facts pointing to Thomas
    Skakel’s involvement, all of which were known to Sher-
    man before the petitioner’s criminal trial. See, e.g., Bry-
    ant v. Commissioner of Correction, 
    290 Conn. 502
    , 513,
    
    964 A.2d 1186
     (‘‘a court deciding an actual ineffec-
    tiveness claim must judge the reasonableness of coun-
    sel’s challenged conduct on the facts of the particular
    case, viewed as of the time of counsel’s conduct’’ [inter-
    nal quotation marks omitted]), cert. denied sub nom.
    Murphy v. Bryant, 
    558 U.S. 938
    , 
    130 S. Ct. 259
    , 
    175 L. Ed. 2d 242
     (2009).
    It is also clear that Sherman’s decision prejudiced the
    petitioner because it deprived him of the opportunity to
    demonstrate to the jury that someone other than he
    had the motive, means and opportunity to kill the victim,
    the raison d’eˆtre of a third-party culpability defense.
    No such argument could be made against Littleton, and
    Sherman’s meager attempt to do so was justifiably exco-
    riated—even ridiculed—by the state. And with good
    reason: as the habeas court observed, ‘‘Sherman essen-
    tially abandoned any third-party culpability claim in his
    jury argument,’’ whereas the halfhearted argument that
    he did make ‘‘actually harmed the defense’’ because it
    communicated to the jury that Sherman himself put no
    stock in it.
    A
    The Kenneth Littleton Evidence
    At the time of the victim’s murder, Littleton, a then
    twenty-four year old graduate of Williams College with
    no known history of mental illness or violence, was
    completing his second month of teaching and coaching
    at the Brunswick School (Brunswick), a private school
    in Greenwich. Shortly after his arrival at Brunswick, the
    headmaster informed him that the petitioner’s father,
    Rushton Skakel, Sr., was in need of a live-in tutor for
    his children. Littleton accepted the position and, as fate
    would have it, spent his first night in residence at the
    Skakel home on October 30, 1975, the night of the mur-
    der, arriving there at approximately 4:30 p.m. Because
    Rushton Skakel, Sr., was out of town at the time, Little-
    ton’s duties included babysitting for the younger Skakel
    children, nine year old Stephen Skakel and twelve year
    old David Skakel, until their father’s return. There is
    no evidence that Littleton, who had just moved to
    Greenwich to teach, had ever been to the Skakels’ neigh-
    borhood prior to the evening of October 30, 1975, or
    had ever met or laid eyes on the victim. This fact alone
    eliminated him as a suspect for most of the officers
    involved in the investigation based on the widely held
    belief that only someone familiar with the victim and
    the neighborhood would have known to conceal the
    victim’s body under the pine tree behind her parents’
    house, or would have been able to locate that tree in
    the dark. Sherman was also aware that the petitioner’s
    sister, Julie Skakel, had observed Littleton in the Ska-
    kels’ kitchen, at approximately 10 p.m., the victim’s
    time of death as established by the substantial weight
    of the evidence at trial, and as argued by the defense.
    The Greenwich police followed numerous leads in
    the months and years following the murder. In 1976,
    the police prepared an arrest warrant charging Thomas
    Skakel with the victim’s murder based, in part, on false
    statements that he had given to them following the
    murder, his history of mental instability and violence,
    and because he was the last person to be seen with
    the victim prior to her death. The warrant was never
    approved, however, and the case ultimately went cold
    for nearly fifteen years.
    At the most basic level, therefore, Littleton made for
    an unlikely target, and, for a long period of time, he
    was treated as such. In 1991, however, the Office of
    the State’s Attorney reopened the investigation, and
    suspicion soon fell on Littleton, who, in the intervening
    years, had developed a severe alcohol addiction and
    had been diagnosed with bipolar disorder, which
    caused him to act erratically at times. In 1991, Detective
    Frank Garr and Inspector John F. Solomon traveled to
    Canada to interview Littleton’s former wife, Mary
    Baker, in the hope that she might be able to shed light
    on the investigation. Baker agreed to assist Garr and
    Solomon because she ‘‘thought it was the right thing
    to do,’’ even though she did not believe Littleton had
    anything to do with the victim’s murder. Initially, Baker
    simply recorded her telephone conversations with Lit-
    tleton, during which she would ask him questions about
    the murder. According to Garr, he and Solomon ‘‘guided
    [Baker with respect to] how to proceed with these con-
    versations between her and her [former] husband in
    the attempt to get him to open up and discuss the crime
    and possibly his complicity in it.’’ Specifically, Garr and
    Solomon ‘‘suggested to her’’ what to say ‘‘to see what
    type of a response’’ it would elicit from Littleton.
    According to Garr, this approach never elicited a single
    incriminating response.
    In December, 1991, Baker agreed to go to Boston,
    Massachusetts, and meet with Littleton in person, at a
    hotel, under the pretext of discussing the possibility of
    getting back together with him. The plan called for
    Baker to tell Littleton that the reason she was reluctant
    to get back together with him was because, several
    years earlier, while she and he were driving through
    Connecticut on their way to Massachusetts, he had con-
    fessed to the victim’s murder during a drunken
    blackout.
    Littleton, who wanted very much to reunite with
    Baker, agreed to the meeting. A transcript of their con-
    versation, which was secretly recorded by the police,
    was provided to Sherman prior to trial. As planned,
    Baker began the conversation by telling Littleton about
    his so-called admissions. Shocked by the news, Littleton
    strenuously denied any involvement in the victim’s mur-
    der, insisting that he never laid eyes on her ‘‘that night
    or ever . . . .’’ Littleton also told Baker that he was
    willing to do whatever it took to convince her of his
    innocence, including submitting to a ‘‘sodium pento-
    thal’’ test administered by the Greenwich police, which
    he hoped might finally answer a question that had vexed
    the police at the time of the murder. Littleton explained
    that ‘‘the key thing that they were interested in [was]
    what [Thomas Skakel] was wearing when he came into
    the room to watch [television later in the evening]. And
    I couldn’t tell them that.’’ Littleton testified that ‘‘this
    was a big key point they really hammered . . . but I
    couldn’t remember [if Thomas Skakel] was wearing
    something different . . . versus what he was wearing
    earlier in the evening.’’
    After his meeting with Baker, Littleton agreed to meet
    with Kathy Morall, a forensic psychiatrist retained by
    the Greenwich police to evaluate him as a possible
    suspect. At the time of their meeting, Littleton was
    unaware of the ruse that the police and Baker had
    played on him in Boston. During their first meeting,
    Littleton told Morall of the ‘‘frightening’’ news that he
    had received from Baker. Specifically, Littleton
    informed Morall that Baker had told him that, during
    a trip through Connecticut, ‘‘I was blacked out for about
    [one] hour to [one] hour and fifteen minutes. . . .
    [Baker] said that I was in the backseat . . . . She told
    me that I said I did it.’’ At their next meeting, while
    discussing the same car ride, Littleton reminded Morall,
    ‘‘I told you this, you know, it’s kind of frightening but
    . . . this is when I said, I did it. . . . [Baker] heard
    me.’’ This statement, ‘‘this is when I said, I did it’’;
    (emphasis added); provided the crux of Sherman’s
    third-party culpability defense against Littleton. During
    his cross-examination of Littleton at the petitioner’s
    criminal trial, Sherman asked Littleton whether he had
    ever told Morall that he had told Baker, ‘‘I did it,’’ mean-
    ing that he had murdered the victim. Littleton answered,
    ‘‘[y]es.’’ Littleton explained, however, that he had only
    said that to Morall because that is what Baker had told
    him, not because he had any memory of confessing
    to the victim’s murder. Littleton testified that it never
    occurred to him at the time of his meeting with Morall
    that Baker, a person whom he loved and trusted, would
    lie to him about such a thing.
    Convinced beyond any conceivable doubt that Little-
    ton had absolutely nothing to do with the murder, the
    state granted him full immunity—effectively exonerat-
    ing him in the eyes of the jury—and, at trial, completely
    discredited Sherman’s unpersuasive attempt to depict
    Littleton as a suspect. The state’s task was not a difficult
    one in light of Baker’s testimony, corroborated by Garr
    and Solomon, that everything she had told Littleton was
    part of a ruse, as State’s Attorney Benedict put it, ‘‘to
    dupe [a] psychologically fragile person to confess to
    [a] crime [he did not commit] . . . .’’ Benedict
    explained that, in 1992, Garr and Solomon got it into
    their heads that they were ‘‘going to break the case by
    tricking . . . Littleton into confessing. . . . There is
    no question that [their plan] . . . was a complete flop.’’
    Benedict further argued that, obviously, ‘‘the evidence
    of Littleton’s interview by Morall was simply a product
    of his having been hoodwinked in Boston. For counsel
    to suggest to you here that what Littleton said to Morall
    is a confession is really treating you no differently than
    the police treated Littleton . . . in 1992.’’
    By the end of the petitioner’s criminal trial, Sherman
    himself effectively conceded that his attempts to incul-
    pate Littleton were not merely fruitless for his client
    but fundamentally baseless as a strategic matter, as
    evidenced by his assertion that he had ‘‘no clue, no
    clue’’ whether Littleton was responsible for the victim’s
    murder. Moreover, Sherman stated, in referring to Lit-
    tleton’s so-called ‘‘confession,’’ ‘‘[a]t the very least, what
    we learned from . . . Littleton is, you know, a confes-
    sion ain’t always a confession, is it,’’ clearly expressing
    the view that Littleton’s supposed confession was
    hardly that. In fact, at one point during his closing
    argument, Sherman quite reasonably stated that ‘‘who-
    ever did [commit] this crime . . . should rot in hell.’’
    But shortly thereafter, when again discussing Littleton,
    Sherman stated that, ‘‘I thought that he was a very
    pathetic creature. I felt very badly for him. I don’t think
    I beat him up too much on the stand.’’ At another point,
    Sherman argued to the jury that the state should be
    ‘‘comforted by the fact’’ that it ‘‘didn’t make the wrong
    decision by arresting . . . Littleton.’’ One is left only
    to observe that it is hard to imagine a closing argument
    that does more to undermine a key aspect of a party’s
    claim.18 As the habeas court generously noted, Sher-
    man’s bizarre closing argument ‘‘essentially eviscer-
    ated’’ any third-party culpability defense predicated on
    Littleton’s commission of the murder19 and was itself
    deficient.20
    As the habeas court further concluded, when the
    Littleton evidence is compared to the powerful evidence
    implicating Thomas Skakel, Sherman’s failure to assert
    a third-party culpability defense against Thomas Skakel
    ‘‘was and is inexplicable’’ and ‘‘cannot be excused as
    a reasonable exercise of judgment or [as] a matter of
    trial strategy.’’ Even ‘‘[i]f Sherman was, in fact, commit-
    ted to the notion that only one third-party culpability
    defense should be asserted, a proposition [that] may
    well be within trial counsel’s informed discretion, he
    unreasonably chose a third party against whom there
    was scant evidence and ignored a third party against
    whom there was a plethora of evidence.’’ I turn to the
    latter evidence now.
    B
    The Thomas Skakel Evidence
    At the time of her death, the victim had been
    acquainted with Thomas Skakel and the petitioner for
    approximately eight weeks. It is undisputed that
    Thomas Skakel was the last person to be seen with her
    prior to her death. Seven different witnesses reported
    seeing them alone in his driveway at approximately 9:30
    p.m. In a tape-recorded interview following the murder,
    the victim’s friend, Ix, reported that, on the night of the
    murder, at approximately 9:15 p.m., she, the victim, the
    petitioner and an eleven year old boy named Geoffrey
    Byrne were seated in the Skakels’ Lincoln Continental
    in the Skakel driveway talking, when Thomas Skakel
    came outside and joined them. At that time, the petition-
    er’s older brothers, John Skakel and Rushton Skakel,
    Jr., and their cousin, Terrien, approached the car and
    told them that they needed to use it to drive Terrien
    home. When asked by the police whether everyone got
    out of the car at that point, Ix responded: ‘‘Not everyone.
    Just [Thomas Skakel], and me, and [the victim and
    Byrne].’’ Ix reported that she and Byrne then left for
    their respective homes, and, as they were leaving, the
    victim stated, ‘‘I’m going home in a few minutes,’’ too.
    Both Ix and Byrne reported that, as they were walking
    out of the driveway, ‘‘they observed Thomas [Skakel]
    push [the victim],’’ causing her to ‘‘[trip] over a small
    steel curbing surrounding a planted area.’’ Ix and Byrne
    ‘‘reported that they did not see [the victim] return to
    the driveway’’ after that.
    The victim’s mother telephoned the Greenwich police
    at 3:48 a.m. on October 31, 1975, to report the victim
    missing. During that telephone call, she reported that
    the victim had been ‘‘expected home at 9:30 p.m.’’ and
    ‘‘had never been late like this before.’’ She also reported
    that she had called several of the victim’s friends before
    calling the police and had been told by one to ‘‘check
    with the . . . Skakels . . . .’’ The victim’s mother
    reported that she then ‘‘called the Skakel residence
    . . . and spoke to Thomas [Skakel],’’ who told her that
    he last saw the victim at approximately 9:30 p.m. on
    October 30, and that the victim had told him that she
    was going home to do her homework. At trial, the vic-
    tim’s mother testified that her daughter ‘‘always came
    home’’ when expected and that her failure to do so on
    the night of the murder was ‘‘an aberration.’’
    The police interviewed Thomas Skakel following the
    discovery of the victim’s body, and he told them that,
    on the night of the murder, at approximately 9:15 p.m.,
    he went outside to his father’s Lincoln Continental to
    get an audio cassette. When he got to the car, the peti-
    tioner, Ix, Byrne, and the victim were sitting inside the
    car, talking, and he decided to join them. After a few
    minutes, his brothers John Skakel, Rushton Skakel, Jr.,
    and his cousin, Terrien, approached the car and told
    them that they were going to take Terrien home. Consis-
    tent with Ix’ statement to the police, Thomas Skakel
    reported that he, Ix, Byrne, and the victim got out of
    the car and that John Skakel, Rushton Skakel, Jr., and
    Terrien got into the car with the petitioner and departed
    for Terrien’s house. Thomas Skakel further stated that
    after he, Ix, Byrne, and the victim got out of the car,
    Ix and Byrne went home, leaving Thomas Skakel and
    the victim alone in the driveway. Thomas Skakel
    reported that ‘‘he talked to [the victim] for a few
    minutes, said goodnight, and entered [his] house
    [through] the side door.’’ Thomas Skakel’s sister, Julie
    Skakel, reported to the police that she observed Thomas
    Skakel enter the side kitchen door at approximately
    9:25 to 9:30 p.m., as she was leaving to take her friend
    Shakespeare home. According to Thomas Skakel, he
    then went to his bedroom to complete a homework
    assignment on Lincoln Log cabins. Thomas Skakel fur-
    ther stated that, at approximately 10:15 p.m., he went
    to his father’s bedroom and watched television with
    Littleton for approximately fifteen minutes. When con-
    fronted with the fact that Ix and Byrne had seen him
    push the victim into the bushes, Thomas initially denied
    that he had done so but then admitted to ‘‘horse play-
    ing.’’ When asked whether he kissed or attempted to
    kiss the victim, or had had any sexual desire for the
    victim, Thomas Skakel answered, ‘‘no.’’
    Thomas Skakel became the prime suspect in the vic-
    tim’s murder after the police learned from his teachers
    that he had lied about his homework assignment, and
    learned from Littleton that Thomas Skakel was not in
    his bedroom at 10 p.m. In the course of their investiga-
    tion, the police also learned from a number of witnesses
    that Thomas Skakel was an emotionally unstable teen-
    ager who was prone to ‘‘frequent and quite sudden
    outbursts of severe physical violence,’’ the apparent
    result of a traumatic head injury, which made him
    ‘‘impulsive and [susceptible] to precipitous outbursts
    of anger. He would rant and rave, be extremely noisy,
    and, on one occasion, [he] put his fist through a door.’’
    (Internal quotation marks omitted.) On other occasions,
    he reportedly ‘‘stabbed his brother in the head with a
    fork,’’ ripped a telephone out of a wall, and ‘‘beat the
    crap’’ out of an opponent during a soccer game. Wit-
    nesses also informed the police that Thomas Skakel
    frequently walked around the neighborhood carrying a
    golf club21 and that, shortly after the victim’s murder,
    his father committed him to Yale-New Haven Hospital
    for two weeks of psychiatric evaluation. Sherman also
    was aware that Thomas Skakel, by his own admission,
    had consumed ‘‘about four or five’’ beers and ‘‘one or
    two scotches’’ in the space of two or three hours on
    the night of the murder.
    Entries in the victim’s diary further revealed that, in
    the weeks preceding her murder, Thomas Skakel had
    made unwanted sexual advances toward her. In one
    such entry, dated October 4, 1975, the victim wrote that
    ‘‘[Thomas Skakel] was being an ass. At the dance he
    kept putting his arms around me and making moves.’’
    Allison Moore, a friend of the victim’s, corroborated
    the victim’s account of Thomas Skakel’s interest in the
    victim, reporting to the police that, ‘‘just prior to [her
    death], [the victim] informed her that . . . Thomas
    [Skakel] wanted to date her, but that [the victim] had
    refused. [Moore] reported that [the victim] told her that
    Thomas [Skakel] was aggressive, and that [the victim]
    thought [Thomas Skakel was] strange.’’ Another friend,
    Christine Kalan, reported that she also ‘‘was aware of
    the fact that Thomas [Skakel] wanted to date [the vic-
    tim] but that [the victim] just liked [him] as a friend.’’
    The timeline of the murder established by the Green-
    wich police was also highly incriminating with respect
    to Thomas Skakel. The police believed that the victim
    was attacked on her way home from the Skakel drive-
    way sometime between 9:30 and 10 p.m., a conclusion
    based on forensic analysis of the victim’s body,22 the
    extreme agitation of two neighborhood dogs at the edge
    of the crime scene,23 and a loud commotion heard by
    the victim’s mother between 9:30 and 10 p.m. in the
    victim’s yard. The commotion, which consisted of
    ‘‘excited voices’’ and ‘‘incessant barking,’’ was so dis-
    tracting that the victim’s mother stopped what she was
    doing to look out the window. On the basis of this and
    other information, the police concluded: ‘‘Our assump-
    tion is that death occurred about 10 p.m., October [30],
    as the investigation shows that two neighborhood dogs
    were highly agitated shortly before 10 p.m. We feel that,
    even though there was no school the next day, the
    [victim] left the Skakel house and was headed home
    because her friends were not going to remain out any
    longer that night. We have interviewed [400] people,
    and no one saw the [victim] after 9:30 p.m. on the night
    in question. It seems highly unlikely . . . that a . . .
    fifteen year old female would [wander the neighbor-
    hood alone] at night.’’
    In 1994, after Rushton Skakel, Sr., hired Sutton Asso-
    ciates to investigate the victim’s murder; see footnote
    6 of this opinion; Thomas Skakel admitted to the Sutton
    investigators that he had lied to the police in 1975.
    Although he had originally told the police that he last
    saw the victim in his driveway at 9:30 p.m., Thomas
    Skakel now confessed that, after his brothers left to
    take Terrien home, he went inside the house briefly
    and then rejoined the victim for a sexual encounter in
    his backyard that lasted until 9:50 or 9:55 p.m., during
    which he ejaculated. When first interviewed by the
    investigators, Thomas Skakel stated that the victim ini-
    tially ‘‘rejected’’ his advances but then acquiesced. In
    a follow-up interview, however, he portrayed the victim
    as the aggressor, stating that it was the victim who
    pursued him because ‘‘maybe she wanted more of
    Tommy.’’
    Of course, Thomas Skakel’s admissions to the Sutton
    investigators, later repeated to Sherman and Throne,
    placed him with the victim after the neighborhood dog
    began its frantic and violent barking a few feet from the
    crime scene. See footnote 23 of this opinion. Although
    State’s Attorney Benedict, at trial, tried to minimize the
    import of the dog’s behavior relative to the timing of
    the victim’s murder, its significance was not lost on the
    Greenwich police or on any of the forensic investigators
    who advised them in their investigation; all of them
    believed that the dog’s aberrant behavior corresponded
    with the time of the attack. Sherman also considered
    it a crucial piece of evidence because he argued to the
    jury that the dog’s violent barking at 9:45 p.m. ‘‘time
    stamps when this crime occurred.’’ According to the
    defense’s own theory of how the crime unfolded, there-
    fore, Thomas Skakel’s admissions to the Sutton investi-
    gators placed him with the victim at the time of the
    attack.
    In the course of their investigation, Sutton investiga-
    tors interviewed Thomas Skakel’s sister, Julie Skakel,
    whose account of the evening further cast doubt on
    Thomas Skakel’s innocence. She reported that, on the
    night of the murder, at approximately 1:30 a.m., she
    received the first of several telephone calls from the
    victim’s mother, who was trying to locate the victim.
    According to Julie Skakel, she went to Thomas Skakel’s
    room to ask him if he knew where the victim might be
    so that she could report back to the victim’s mother.
    Julie Skakel stated that Thomas Skakel told her that
    the victim had left at 9:30 p.m. and that he had to ‘‘study
    for a test’’ that night. In their suspect profile of Thomas
    Skakel, the Sutton investigators noted that, while there
    may have been an innocuous reason for Thomas Skakel
    to lie to the police about his sexual encounter with the
    victim after learning of her murder, that motive ‘‘would
    originate after Thomas [Skakel] knew [the victim] had
    been murdered. . . . When Julie [Skakel] came into
    his room at 1:30 a.m., however, Thomas [Skakel] was
    untruthful about [having a] test and when he had last
    seen [the victim]. . . . Many divergent and damning
    conclusions can be drawn when speculating about the
    significance of [these lies],’’ which were told at a time
    when presumably only the killer knew that the victim
    was dead. Thomas Skakel also lied to the victim’s
    mother when he spoke to her in the early morning hours
    of October 31, 1975. As I previously indicated, Thomas
    Skakel told her that the victim had left his house at 9:30
    p.m., stating that she was going home to do homework.
    Sherman also had firsthand knowledge of Thomas
    Skakel’s admissions because he and Throne met with
    Thomas Skakel and his attorney, Emanuel Margolis, on
    the eve of the petitioner’s criminal trial. At that time,
    according to Sherman’s habeas trial testimony, Margolis
    ‘‘allowed [Sherman and Thorne] to speak to [Thomas
    Skakel] about anything [they] wanted . . . .’’ Both
    Sherman and Throne testified at the habeas trial that
    they had read the Sutton Report prior to their meeting
    with Thomas Skakel and were aware of the information
    contained in it relative to him. Sherman specifically
    acknowledged that he was aware that, ‘‘[o]n October
    7, 1994, Thomas [Skakel] broke down in tears and
    informed [the] Sutton [i]nvestigators that he had, in
    fact, spent at least an additional twenty minutes with
    [the victim] behind his house. . . . They began an
    extended . . . twenty [minute] kissing and fondling
    session, which include[d] mutual fondling . . . and
    . . . concluded when both masturbate[d] [the other] to
    orgasm. At [that] point, approximately 9:50 p.m., both
    [the victim] and [Thomas Skakel] rearranged their
    clothes, and [the victim] . . . is last seen by [Thomas
    Skakel] hurrying across the rear lawn [toward] her
    home. [Thomas Skakel] stated that . . . he opened [the
    victim’s] pants, slightly pushing them down, [and] fon-
    dled her vagina . . . . Thomas [Skakel] . . . stated
    [that] he soiled his clothing . . . when [the victim]
    brought him to . . . orgasm using her hand on his
    penis.’’ Sherman testified that ‘‘[Thomas Skakel’s] dis-
    cussion with [him] was consistent with what was in the
    Sutton Report. . . . He repeated the version of events
    as you recited [from] the Sutton Report.’’ Sherman
    stated, moreover, that he and Throne took notes during
    the meeting.
    Throne also testified at the petitioner’s habeas trial
    about his and Sherman’s 2002 meeting with Thomas
    Skakel. Although he could not remember the specifics
    of what was said at the meeting, he did recall that it
    made a ‘‘significant impression’’ on him because
    Thomas Skakel admitted to having lied to the police
    about when he last saw the victim. In particular, Throne
    remembered that Thomas Skakel told them that he and
    the victim were together after the time that the police
    believed that they had parted ways.
    At the habeas trial, the petitioner’s habeas counsel
    asked Sherman why, in light of the litany of evidence
    implicating Thomas Skakel in the victim’s murder, he
    did not pursue a third-party culpability claim against
    him, particularly given the defense’s theory that the
    victim was attacked at 9:45 p.m. Sherman responded
    that Thomas Skakel ‘‘was going to invoke the fifth
    amendment [privilege] no matter what we did, and I
    [did not think] ethically I could put him on the stand
    knowing that he was going to invoke the fifth amend-
    ment privilege.’’ Sherman further testified: ‘‘I told
    [Thomas Skakel’s attorney], I’m calling him as a witness.
    [Thomas Skakel’s attorney] told me in no uncertain
    terms that he’s not going to testify because he will claim
    the fifth amendment privilege.’’ Specifically, Sherman
    stated: ‘‘I’m sorry. [I was] not the one trying . . . to
    protect [Thomas] Skakel, but he would not testify, and
    I don’t think the third-party culpability issue would have
    worked [otherwise].’’ Although Sherman acknowledged
    that he did not believe in ‘‘putting out a buffet table
    of alleged suspects,’’ he emphasized that his ‘‘[p]rime’’
    reason for not implicating Thomas Skakel was that he
    did not think it would have been successful without
    Thomas Skakel’s testimony. Sherman explained: ‘‘My
    client was [the petitioner]. I bore no allegiance; I bear
    no allegiance to anyone but [the petitioner]. If I had
    . . . something that I deemed was credible enough to
    pass [the court’s] third-party culpability threshold, I
    would have used it. . . . I don’t think we reached that
    threshold [with Thomas Skakel]. I don’t think it was
    there. I wish it was.’’
    But it was there. As the habeas court concluded,
    Thomas Skakel’s statements against penal interest
    could have been presented to the jury through Throne,
    who readily could have been called to testify about
    them.24 Of course, it would have been preferable for
    Sherman to have had a nonattorney witness present
    when interviewing Thomas Skakel because Throne
    could not participate in the trial both as counsel and
    as a witness. In this case, however, Throne undoubtedly
    was more valuable to the petitioner as a witness than
    as Sherman’s inexperienced third chair at trial.25 If nec-
    essary, Sherman also could have called Margolis to tes-
    tify, since Thomas Skakel’s admissions in the presence
    of third parties would not have been protected by the
    attorney-client privilege. See, e.g., State v. Cascone, 
    195 Conn. 183
    , 186, 
    487 A.2d 186
     (1985) (‘‘Communications
    between client and attorney are privileged when made
    in confidence for the purpose of seeking legal advice.
    . . . By contrast, statements made in the presence of
    a third party are usually not privileged because there
    is then no reasonable expectation of confidentiality.’’
    [Citations omitted.]); see also Ullmann v. State, 
    230 Conn. 698
    , 713, 
    647 A.2d 324
     (1994) (attorney-client
    privilege ‘‘protects only those disclosures—necessary
    to obtain informed legal advice—which might not have
    been made absent the privilege’’ [emphasis omitted;
    internal quotation marks omitted]); Ullmann v. State,
    supra, 710 (attorney-client privilege ‘‘is strictly con-
    strued because it tends to prevent a full disclosure of
    the truth in court’’ [internal quotation marks omitted]).
    It is apparent, therefore, that Sherman could have
    put Thomas Skakel’s highly incriminating admissions
    before the jury, either through Throne or Margolis, and
    that he wanted to do so as a key component of a third-
    party culpability defense built around Thomas Skakel.
    But he was unaware that the law permitted him to do
    so; he thought that the only way that he could make
    the jury aware of those admissions was through Thomas
    Skakel’s direct testimony. It is well established that the
    influence of a mistake of law on an attorney’s decision
    making cannot be characterized as a matter of trial
    strategy under Strickland. See, e.g., Hinton v. Alabama,
    U.S.    , 
    134 S. Ct. 1081
    , 1089, 
    188 L. Ed. 2d 1
     (2014)
    (‘‘[a]n attorney’s ignorance of a point of law that is
    fundamental to his case combined with his failure to
    perform basic research on that point is a quintessential
    example of unreasonable performance under Strick-
    land’’); Williams v. Taylor, 
    529 U.S. 362
    , 373, 
    120 S. Ct. 1495
    , 
    146 L. Ed. 2d 389
     (2000) (petitioner was denied
    right to effective assistance of counsel when defense
    counsel failed to investigate and present substantial,
    mitigating evidence during sentencing phase of capital
    murder trial, not for any tactical reason, but because
    he erroneously believed that law did not permit him
    to present such evidence). Thus, insofar as Sherman’s
    decision not to present a third-party culpability defense
    centered on Thomas Skakel resulted from Sherman’s
    mistaken belief that that defense required Thomas Ska-
    kel’s testimony, the decision was not reasonable
    under Strickland.
    The importance of Thomas Skakel’s admissions to
    the defense was great. The great weight of the trial
    evidence established that the victim was attacked at
    approximately 9:45 p.m. Unlike Thomas Skakel, who
    could not account for his whereabouts between 9:30
    and 10:20 p.m., the petitioner had a strong alibi for that
    time frame, which is why the state took the bold position
    that the petitioner’s alibi witnesses were all lying to
    protect him. If the defense had offered the jury a plausi-
    ble third-party culpability suspect, however, the jury
    would have viewed the state’s speculative argument
    concerning the petitioner’s alibi in a far different light.
    As the habeas court noted: ‘‘[Sherman’s] task . . .
    would not have been to convince the jury that [Thomas]
    Skakel committed the murder; rather, he needed only
    to argue that the direct and circumstantial evidence
    regarding [Thomas] Skakel’s potential culpability
    should, at least, create a reasonable doubt in the minds
    of the [jurors] as to the petitioner’s guilt. As presented,
    [Sherman’s] defense deprived the petitioner of an
    opportunity for the jury to hear [Thomas] Skakel’s
    admission of a sexual encounter with the victim, and
    for . . . Sherman to point out the compatibility of
    some aspects of this story with the physical crime scene
    findings regarding the victim’s [state of undress]. . . .
    Sherman deprived the petitioner of an opportunity to
    present [Thomas] Skakel’s consciousness of guilt [in
    his] change of stories, his growing sexual interest in
    and aggressiveness toward the victim leading to the
    date of her murder, and the police awareness that he
    had a history of emotional instability.’’
    The habeas court further noted: ‘‘At trial, the jury
    heard only that when the Lincoln [Continental] left the
    Skakel property, [Thomas] Skakel and the victim were
    standing together in the driveway. Significantly, the jury
    heard nothing regarding a sexual encounter between
    [Thomas] Skakel and the victim. However, it is reason-
    able to conclude that, in a competently presented third-
    party culpability claim regarding [Thomas] Skakel, a
    jury would have heard testimony that [Thomas] Skakel
    claimed that he had been engaged with the victim in a
    consensual sexual encounter to the rear of the Skakel
    property [until 9:50 p.m.] on October 30, 1975, during
    which he unfastened her [pants] and partially lowered
    [them] while [they both] engaged in mutual masturba-
    tion; that no living person could account for [Thomas]
    Skakel’s whereabouts between 9:15 p.m. and approxi-
    mately 10:17 p.m., when [Thomas Skakel] joined Little-
    ton to watch [television]; that [Thomas] Skakel initially
    had lied to the Greenwich police about his whereabouts
    and activities after approximately 9:15 p.m. that eve-
    ning; and [that] he had lied to [the police and] Littleton
    about having worked on a homework assignment in his
    father’s room. The jury would also have heard that no
    one ever reported seeing the victim alive after she and
    [Thomas] Skakel were seen together in the Skakel drive-
    way as the Lincoln [Continental] left for the Terrien
    home at approximately 9:15 p.m. Based on the availabil-
    ity of this evidence to . . . Sherman, [there is] little
    doubt that the trial court would have permitted the
    petitioner to assert a third-party culpability claim
    regarding [Thomas] Skakel.’’ (Footnote omitted.)
    Indeed, on the basis of the evidence known to Sher-
    man at the time of the petitioner’s criminal trial, Sher-
    man could have argued persuasively to the jury as
    follows. Finding herself alone with Thomas Skakel in
    the driveway at 9:25 p.m., the victim told him that she
    had to leave, too, because she was due home at 9:30
    p.m. Thomas Skakel then offered to walk the victim
    home and asked her to wait while he grabbed a jacket,
    or used the bathroom, since he had been drinking heav-
    ily. Such a scenario was consistent with Julie Skakel’s
    testimony that she saw Thomas Skakel enter the house
    through the side door at 9:30 p.m. Thomas Skakel then
    rejoined the victim outside, grabbing a golf club from
    the bucket by the door as he left the house, as was his
    custom according to various witnesses. While en route
    to the victim’s house, an intoxicated Thomas Skakel
    made a pass at the victim, and what may or may not
    have been initiated as a consensual sexual encounter
    between them turned suddenly violent when the victim
    rejected his advances or withdrew her consent for fur-
    ther physical contact. Infuriated by her rejection,
    Thomas Skakel struck the victim with the golf club,
    which, in his rage, became a weapon of convenience.
    Consistent with the forensic evidence, the victim was
    able to get away from Thomas Skakel after the initial
    assault, but Thomas Skakel caught up with her, struck
    her repeatedly with the golf club and then dragged her
    lifeless body to the pine tree behind her house. Thomas
    Skakel’s assault on the victim was undoubtedly the
    commotion that the victim’s mother heard between 9:30
    and 10 p.m., and the event that caused one of the neigh-
    borhood dogs to commence its incessant and plaintive
    barking at the entrance to the victim’s driveway.
    Thomas Skakel then ran home, which would have taken
    him less than one minute according to the evidence
    adduced at trial, removed his bloodstained clothing and,
    thirty minutes later, joined Littleton to watch television
    with him, in an effort to establish an alibi.
    Testimony by Thomas Skakel’s family, friends and
    teachers regarding his violent temper would only have
    strengthened Sherman’s argument, as would the vic-
    tim’s diary and the testimony of her friends regarding
    Thomas Skakel’s aggressiveness toward her before her
    death. To reinforce his argument, Sherman needed only
    to remind the jury that Thomas Skakel, by his own
    admission, had placed himself with the victim after the
    neighborhood dog began its violent barking at 9:45 p.m.,
    that he was hospitalized for two weeks shortly after
    the murder for psychiatric evaluation, that he had lied
    about his whereabouts between the hours of 9:30 and
    10:20 p.m. not only to the police, but also to his sister
    and the victim’s mother before anyone knew that the
    victim was dead. Sherman could have argued that
    Thomas Skakel’s guilt was consistent not only with the
    forensic evidence but with the victim’s last words to
    Ix at 9:25 p.m., that she was ‘‘going home’’ soon, and
    with the victim’s mother’s statement to the police that
    the victim had been due home at 9:30 p.m.
    Finally, and perhaps most important, Sherman could
    have argued to the jury that this scenario required no
    more speculation—indeed, I would argue that it
    required considerably less speculation—than the state’s
    argument with respect to the petitioner, namely, that
    all of his alibi witnesses were lying and that the peti-
    tioner must have jumped out of the Lincoln Continental
    after it left the driveway, found a golf club lying about
    in the dark, waited for the victim near her house, and
    then bludgeoned her as she entered the driveway, all
    because he had seen her ‘‘carrying on’’ with Thomas
    Skakel, as Benedict characterized Thomas Skakel’s con-
    duct. In short, in stark contrast to Sherman’s claim that
    Littleton may have murdered the victim—a claim for
    which there was absolutely no support in the evi-
    dence—the evidence against Thomas Skakel provided
    an opportunity for Sherman to present a coherent and
    compelling third-party culpability defense—a defense
    that he, for no legally or strategically valid reason, failed
    to employ.26
    C
    The Majority’s Conclusions
    The majority rejects the habeas court’s determination
    that Sherman’s failure to implicate Thomas Skakel in
    the victim’s murder was objectively unreasonable, but
    not for any of the reasons that Sherman gave at the
    petitioner’s habeas trial. Rather, because, in the majori-
    ty’s view, the evidence did not support the habeas
    court’s finding that Thomas Skakel discussed ‘‘the
    details’’ of his sexual encounter with the victim when
    he met with Sherman and Throne in 2002, the habeas
    court incorrectly concluded that Sherman could have
    put Throne on the stand to testify about Thomas Ska-
    kel’s admissions. The majority also concludes that the
    habeas court’s finding that Throne could have testified
    about the admissions was ‘‘entirely speculative’’ in light
    of Throne’s inability, at the petitioner’s 2013 habeas
    trial, to remember the specifics of what was discussed
    at the 2002 meeting, apart from the fact that Thomas
    Skakel admitted to having lied to the police about when
    he had last seen the victim. The majority is mistaken
    on both counts.
    First, it is abundantly clear that Thomas Skakel did
    discuss the details of his sexual encounter with the
    victim. After the petitioner’s habeas counsel read aloud
    from the portion of the Sutton Report describing when,
    where and how the sexual encounter unfolded, Sher-
    man stated that Thomas Skakel ‘‘basically repeated
    . . . the version of events as you recited or read [from]
    the Sutton Report . . . .’’ Sherman later confirmed that
    ‘‘his . . . discussion with [him] was consistent with
    what was in the Sutton Report.’’ Sherman also testified
    that Thomas Skakel ‘‘recounted’’ his sexual encounter
    with the victim at the meeting. At another point, Sher-
    man testified that it was not his impression from talking
    to Thomas Skakel that the encounter involved sexual
    intercourse, only ‘‘sexual play,’’ something of the nature
    of ‘‘touching, masturbation, mutual masturbation, that
    kind of stuff.’’ Sherman further testified that the encoun-
    ter occurred ‘‘ten minutes before . . . 10 p.m.’’
    The majority does not explain what additional details
    about the sexual encounter were required for Sherman
    to assert a strong third-party culpability claim against
    Thomas Skakel. The fact is that Sherman had all of the
    information he needed. Indeed, it was not the precise
    nature of Thomas Skakel’s purported sexual encounter
    with the victim that mattered. It was the fact that he
    had one at all that mattered because it allowed Sherman
    to argue to the jury that Thomas Skakel had lied to the
    police when he told them that there had been no such
    encounter and that the victim had left his house at 9:30
    p.m. In any event, it is readily apparent that the habeas
    court’s finding that Thomas Skakel discussed his sexual
    encounter with the victim when he met with Sherman
    and Throne in 2002 is supported by the habeas trial
    record. It is the majority’s finding to the contrary that
    is belied by the record.
    The majority also concludes that ‘‘[a]ny finding con-
    cerning the details that Throne could have relayed to
    the jury about Thomas Skakel’s alleged encounter with
    the victim would . . . be entirely speculative’’ in light
    of Throne’s inability to recall, in 2013, what was dis-
    cussed at the 2002 meeting, beyond the fact that Thomas
    Skakel’s admission had made a significant impression
    on him because Thomas Skakel acknowledged that he
    was with the victim much longer than what he had told
    the police. The majority must do better than this. It
    simply cannot be the position of this court—or any
    court—that it is entirely speculative to conclude that
    defense counsel would remember bombshell revela-
    tions favorable to his or her client long enough to be
    able to testify about them at the client’s murder trial a
    few days later, if called on to do so. If competent counsel
    has a duty under Strickland that ‘‘includes the obliga-
    tion to investigate all witnesses who may have informa-
    tion concerning [the defendant’s] guilt or innocence’’;
    Towns v. Smith, supra, 
    395 F.3d 258
    ; it is axiomatic that
    he also has a duty to remember what those witnesses tell
    him—at least long enough to act on the information for
    the benefit of his client. This applies in spades to a
    witness as important to the defense as Thomas Skakel,
    for years the prime suspect in the victim’s murder, and
    who, in accordance with their own timeline of the crime,
    Sherman and Throne had every reason to believe was
    with the victim at the time of her death.
    Accordingly, Throne’s inability to recall in 2013 the
    specifics of what was discussed at the 2002 meeting is
    simply irrelevant. The only issue that matters is whether
    he would have remembered what was discussed imme-
    diately following the meeting. That is when the peti-
    tioner claims that Sherman’s representation was
    ineffective insofar as he failed to call Throne as a wit-
    ness to repeat Thomas Skakel’s admissions. The habeas
    court was absolutely correct that, under Strickland and
    its progeny, there is only one answer to that question
    and that is, of course, that he would have remembered.
    The majority finally contends that, even if Throne
    could have testified as to Thomas Skakel’s admissions,
    Sherman reasonably could have decided to forgo impli-
    cating Thomas Skakel in the victim’s murder because
    there was no evidence that his sexual encounter with
    the victim turned violent, or because implicating
    Thomas Skakel ran the risk of strengthening the state’s
    theory that the petitioner murdered the victim in a jeal-
    ous rage. The majority thus suggests that ‘‘defense coun-
    sel in Sherman’s position reasonably could have
    concluded that it was better to pursue a suspect [Little-
    ton] who had at least arguably implicated himself in the
    crime.’’ Again, neither of these contentions holds water.
    First, Littleton inarguably did not implicate himself
    in the victim’s murder, a fact that, as Benedict argued
    at the petitioner’s criminal trial, would not have been
    lost on a child much less on a jury of twelve adults.
    Indeed, even Sherman could not make a straight-faced
    argument tying Littleton to the murder.
    Moreover, the facts simply do not support the majori-
    ty’s low estimation of the strength of the evidence impli-
    cating Thomas Skakel. Indeed, one is hard-pressed to
    find a Connecticut case—or a case from any other juris-
    diction—in which the evidence of third-party culpability
    was any stronger. The majority certainly has not cited
    one. Not even Sherman claimed that asserting a third-
    party claim against Thomas Skakel was not in the peti-
    tioner’s best interest. While Sherman had plenty of evi-
    dence against Thomas Skakel, he mistakenly believed
    that, without Thomas Skakel’s testimony, he did not
    have enough admissible evidence to satisfy the thresh-
    old for raising such a claim.
    Second, it is simply absurd for the majority to suggest
    that Sherman reasonably could have decided against
    asserting a powerful and compelling third-party culpa-
    bility defense against Thomas Skakel out of concern
    that it would bolster the state’s tenuous theory that the
    then fifteen year old petitioner murdered the victim in
    a jealous rage. As the respondent acknowledges, the
    evidence adduced at trial to support that theory was
    scant at best. Indeed, the respondent can identify only
    two pieces of evidence that supported it. The respon-
    dent first points to a telephone conversation between
    Geranne Ridge and a friend, which the friend secretly
    recorded for Garr, during which Ridge claimed to have
    met the petitioner at a party, and that the petitioner
    told her within minutes of their meeting about ‘‘mastur-
    bating in a tree’’ and murdering the victim because she
    had had sex with Thomas Skakel. At the petitioner’s
    criminal trial, however, Ridge testified that, although it
    was true that she had once been introduced to the
    petitioner at a party, she did not actually speak to him,
    and everything that she had told her friend on the tele-
    phone was gleaned from ‘‘magazines, newspapers and
    from [the tabloids],’’ like the ‘‘Star, Globe, Inquirer,
    those kinds of things.’’ An embarrassed Ridge testified
    that she had lied to her friend because he ‘‘was always
    bragging about who he knew’’ and Ridge just wanted
    to seem ‘‘more knowledgeable than [she] was’’ about
    the petitioner’s case.
    The only other evidence that the respondent cites in
    support of the theory regarding the petitioner’s motive
    is the trial testimony of Elizabeth Arnold, who stated
    that, in 1978, while she and the petitioner were enrolled
    at Elan School,27 the petitioner told her ‘‘that his brother
    [fucked] his girlfriend . . . well, they didn’t really have
    sex but they were fooling around.’’ On cross-examina-
    tion, Arnold was asked why, when testifying before the
    grand jury, she had failed to mention that the petitioner
    had told her that Thomas Skakel had fooled around
    with his girlfriend. Arnold responded that she did not
    remember it at the time but that reading Fuhrman’s
    book afterward had refreshed her recollection.
    Fuhrman’s book, an entirely speculative account of
    how the murder could have unfolded, appears to have
    refreshed the recollections of many witnesses for the
    prosecution, several of whom came forward only after
    reading it, or after reading or watching a news story
    about it. One key witness, Shakespeare, completely
    altered her account of the night of the murder after
    reading it.28 The central thesis of the book, borrowed
    from one of several theories posited in the stolen Sutton
    files, was that the petitioner and the victim were boy-
    friend and girlfriend and that the petitioner flew into a
    rage upon seeing the victim in a sexual encounter with
    Thomas Skakel. See M. Furhman, Murder In Greenwich
    (1998) p. 215. Indeed, in the book, Fuhrman claimed
    that unnamed sources had told him that the petitioner
    and the victim were once boyfriend and girlfriend. 
    Id.
    Fuhrman also claimed that the victim’s diary ‘‘clearly
    stated that both Skakel boys were romantically inter-
    ested in her. [The victim] also said that while she liked
    Thomas [Skakel], she had to be careful of [the peti-
    tioner].’’ 
    Id.
     The victim’s diary, of course, says nothing
    of the sort. Nor does it appear that Sherman read it; if
    he had, he would have used it to rebut the state’s dubi-
    ous claim as to the petitioner’s motive.29
    Indeed, in her diary, the victim wrote candidly about
    her boyfriends and social exploits during the fifteen
    months that she lived in Greenwich. She was an avid
    chronicler of her adolescent life and enjoyed writing
    about boys—the ones she liked, the ones she did not
    like, the ones she suspected liked her, and so on and
    so forth. If the victim and the petitioner were in a rela-
    tionship during the eight weeks that they knew one
    another, or if the victim suspected that the petitioner
    liked her during that time period, it is safe to say that
    it was the only time that the victim did not write about
    such matters in her diary. It is clear, therefore, that
    the state’s theory as to motive could have been easily
    rebutted by a minimally competent defense attorney
    using the resources available to him, and that it pre-
    sented no obstacle whatsoever to Sherman’s ability to
    present a compelling third-party culpability defense
    implicating Thomas Skakel. The habeas court was abso-
    lutely right to conclude that, by failing to assert such
    a defense, Sherman simply was not acting as the compe-
    tent counsel guaranteed by the sixth amendment.
    III
    PREJUDICE
    There can be little doubt that the petitioner was
    severely prejudiced by Sherman’s deficient perfor-
    mance in his presentation of the petitioner’s alibi and
    third-party culpability defenses. To satisfy the prejudice
    prong of Strickland, ‘‘[the petitioner] must demonstrate
    that there is a reasonable probability that, but for coun-
    sel’s unprofessional errors, the result of the proceeding
    would have been different.’’ (Internal quotation marks
    omitted.) Janulawicz v. Commissioner of Correction,
    
    310 Conn. 265
    , 268 n.1, 
    77 A.3d 113
     (2013). In this con-
    text, a reasonable probability that the result of the trial
    would have been different ‘‘does not require the peti-
    tioner to show that counsel’s deficient conduct more
    likely than not altered the outcome in the case. . . .
    Rather, it merely requires the petitioner to establish a
    probability sufficient to undermine confidence in the
    outcome.’’ (Citation omitted; internal quotation marks
    omitted.) Bunkley v. Commissioner of Correction, 
    222 Conn. 444
    , 445–46, 
    610 A.2d 598
     (1992). Moreover, ‘‘[i]n
    making this determination, a court hearing an ineffec-
    tiveness claim must consider the totality of the evidence
    before the judge or the jury. . . . Some errors will have
    had a pervasive effect on the inferences to be drawn
    from the evidence, altering the entire evidentiary pic-
    ture, and some will have had an isolated, trivial effect.
    Moreover, a verdict or conclusion only weakly sup-
    ported by the record is more likely to have been affected
    by errors than one with overwhelming record support.’’
    (Internal quotation marks omitted.) Gaines v. Commis-
    sioner of Correction, supra, 
    306 Conn. 688
    –89.
    In the present case, as the habeas court observed,
    ‘‘[i]t would be an understatement to say that the state
    did not possess overwhelming evidence of the petition-
    er’s guilt. An unsolved crime for more than two decades,
    there was evidence that initially the Greenwich police
    sought the arrest of [Thomas] Skakel without success
    and then focused on Littleton to no avail before finally
    turning to the petitioner. The evidence adduced at trial
    was entirely circumstantial, consisting . . . [primarily]
    of testimony from witnesses of assailable credibility
    who asserted that, at one time or another and in one
    form or another, the petitioner made inculpatory state-
    ments. The state also adduced, as consciousness of
    guilt evidence, testimony that the petitioner changed
    his initial account to the police of his movements on
    the evening of the murder.’’
    Not only was there no physical evidence connecting
    the petitioner to the crime and no eyewitnesses, few
    of the witnesses who did testify were interviewed by
    the police at the time of the events in question. Almost
    all of the state’s witnesses, in fact, testified based on
    their recollections of those events some twenty-five
    years after the fact. While this would be a concern in
    any murder case, it was especially problematic in the
    present one given the extensive pretrial publicity sur-
    rounding the case. The risk inherent in prosecuting a
    murder case on the basis of twenty-five year old memo-
    ries filtered through such a potentially corruptive lens
    is obvious. Memories rarely improve over time, even
    under the best of conditions. The state’s evidence,
    which, as the habeas court noted, consisted largely of
    the testimony of witnesses of suspect credibility who
    did not come forward until decades after the events in
    question, was hardly so convincing as to render harm-
    less the kinds of grievous errors committed by Sherman
    in his conduct of the petitioner’s criminal trial.
    In the intervening years since the petitioner’s convic-
    tion, unsettling questions have also arisen over the
    veracity of core tenets of the state’s central thesis rela-
    tive to the petitioner’s guilt, weakening what was to
    begin with a less than persuasive case. As the habeas
    court explained in connection with the petitioner’s
    claim that Sherman’s representation was ineffective
    insofar as he failed to challenge one such fundamental
    aspect of the state’s case against him, information con-
    tained in the state’s own investigative file and available
    to Sherman before trial revealed that the state’s argu-
    ment was baseless, and, yet, it went unchallenged by
    the defense.30
    No argument, however, was more central to the
    state’s theory of guilt or damaging to the petitioner than
    that of the alleged conspiracy by the petitioner’s family
    to fabricate an alibi for him. Thus, the prejudicial impact
    of Sherman’s failure to locate and interview Ossorio, a
    critical independent alibi witness with no ties to the
    petitioner’s family, is virtually incalculable because it
    deprived the petitioner of the opportunity to disprove
    the state’s central thesis. Cf. Gaines v. Commissioner
    of Correction, supra, 
    306 Conn. 689
     (‘‘[s]ome errors will
    have had a pervasive effect on the inferences to be
    drawn from the evidence, altering the entire evidentiary
    picture’’ [internal quotation marks omitted]). Moreover,
    in presenting a far weaker alibi defense than would
    have been put forward by competent counsel—one that
    left the door wide open for the state to argue that the
    alibi was predicated solely on the testimony of close
    family members, all of whom were lying to protect the
    petitioner—Sherman’s performance harmed the peti-
    tioner in yet another way, ‘‘for it is generally acknowl-
    edged that an attempt to create a false alibi constitutes
    evidence of the defendant’s consciousness of guilt.’’
    (Internal quotation marks omitted.) Henry v. Poole, 
    409 F.3d 48
    , 65 (2d Cir. 2005), cert. denied,

    ,
    
    126 S. Ct. 1622
    , 
    164 L. Ed. 2d 334
     (2006); see also 
    id.
    (‘‘[T]here is nothing as dangerous as a poorly investi-
    gated alibi. An attorney who is not thoroughly prepared
    does a disservice to his client and runs the risk of having
    his client convicted even [when] the prosecution’s case
    is weak.’’ [Internal quotation marks omitted.]).
    Sherman’s deficient performance resulting from his
    failure to present a powerful third-party culpability
    defense predicated on evidence that the victim was
    killed by the petitioner’s brother, Thomas Skakel, a
    longtime suspect in the victim’s murder, also caused
    the petitioner serious prejudice: it deprived him of the
    opportunity to provide the jury with convincing evi-
    dence that someone other than the petitioner had the
    motive, means and opportunity to kill the victim. This
    is particularly true in light of the fact that Sherman had
    startling new and highly incriminating evidence linking
    Thomas Skakel to the crime, namely, Thomas Skakel’s
    own statement acknowledging both that he had lied
    to investigators about the time that he and the victim
    departed on the evening of October 30, 1975, and that
    he had had a sexual encounter with the victim at the
    scene of the murder when it most likely was committed.
    Such a compelling third-party culpability defense focus-
    ing on Thomas Skakel—in contrast to the foolhardy
    attempt to implicate Littleton—no doubt would have
    raised a reasonable doubt in the jurors’ minds as to
    who murdered the victim. Although the prejudice flow-
    ing from Sherman’s incompetent handling of the peti-
    tioner’s third-party culpability defense is alone more
    than sufficient to require a new trial, when that preju-
    dice is considered along with the prejudice flowing from
    Sherman’s deficient handling of the alibi defense, it
    strains credulity to believe that the petitioner’s trial
    resulted in a verdict worthy of confidence.
    IV
    CONCLUSION
    Under our constitution and system of laws, a defen-
    dant is presumed innocent until he has been found
    guilty beyond a reasonable doubt after a fair trial. A
    critical component of a defendant’s right to a fair trial
    is the right to the effective assistance of counsel. As
    the habeas court aptly observed, counsel’s ‘‘defense of
    a serious felony prosecution requires attention to detail,
    an energetic investigation and a coherent plan of
    defense capably executed.’’ When counsel has not per-
    formed competently in one or more of these respects—
    in the present case, defense counsel was deficient in
    all three areas—and when, as in the present case, a
    review of the record also leads to the conclusion that,
    because of counsel’s deficient performance, confidence
    in the guilty verdict has been undermined, the convic-
    tion is not sufficiently reliable and cannot be permitted
    to stand. Nothing short of a new trial will suffice to
    vindicate the defendant’s right to a proceeding that
    leads to a reliable outcome.
    In recognition of these core principles, more than
    fifty years ago, the United States Supreme Court stated
    that, ‘‘if the right to counsel guaranteed by the [c]onsti-
    tution is to serve its purpose, defendants cannot be left
    to the mercies of incompetent counsel, and . . . judges
    should strive to maintain proper standards of perfor-
    mance by attorneys who are representing defendants
    in criminal cases in their courts.’’ McMann v. Richard-
    son, 
    397 U.S. 759
    , 771, 
    90 S. Ct. 1441
    , 
    25 L. Ed. 2d 763
    (1970). Today, this court shirks its responsibility to
    maintain such standards by upholding a guilty verdict
    reached only after a trial literally riddled with highly
    prejudicial attorney incompetence. One can only trust
    that the petitioner will receive a fairer hearing, one in
    which his right to the effective assistance of counsel
    is accorded due consideration, in the federal courts.
    1
    This right is made applicable to state prosecutions through the due
    process clause of the fourteenth amendment. E.g., Davis v. Commissioner
    of Correction, 
    319 Conn. 548
    , 554, 
    126 A.3d 538
     (2015), cert. denied sub
    nom. Semple v. Davis,         U.S.    , 
    136 S. Ct. 1676
    , 
    194 L. Ed. 2d 801
     (2016).
    2
    With respect to the other seven areas in which Sherman was found to
    have represented the petitioner incompetently, the habeas court was unable
    to conclude that the prejudice flowing from that inadequate representation
    was so great as to warrant a new trial. In his cross appeal, the petitioner
    contends that the habeas court incorrectly concluded that he was not suffi-
    ciently harmed by those seven areas of deficient performance to warrant a
    new trial. In view of my conclusion that the petitioner is otherwise entitled
    to a new trial, I need not address the claims that the petitioner raises in
    his cross appeal.
    3
    The majority expresses its displeasure with my characterization of its
    analysis of the alibi issue as transparently one-sided and unfair, and also
    accuses me more generally of misstating its views. See footnote 1 of the
    majority opinion. With respect to the former, there is no euphemistic way
    to describe the majority’s analysis: it completely ignores the countervailing
    considerations that the habeas court found to be decisive and provides no
    reason or justification for doing so. With respect to the latter, the majority
    does not identify any of the views that it claims I have misstated, and I
    know of none.

    Testimony established that the Terrien home is about a twenty minute
    car ride from the Skakel home.
    5
    For example, at one point, Littleton was a suspect, but he ultimately
    was cleared of any possible involvement in the murder. Indeed, prior to the
    petitioner’s criminal trial, Littleton was given immunity from prosecution
    by the Office of the State’s Attorney, presumably so that he would be willing
    to testify at the petitioner’s criminal trial to rebut the petitioner’s contention
    that he, Littleton, might have killed the victim. See part II of this opinion.
    6
    The petitioner’s father, Rushton Skakel, Sr., who is now deceased, hired
    Sutton Associates to investigate the victim’s murder in the apparent hope
    of exonerating his family members. According to Leonard Levitt, a journalist
    who has written extensively about the case, Rushton Skakel, Sr., gave those
    investigators free rein to pursue the investigation wherever it led them,
    purportedly assuring them that, if it turned out that a member of his family
    was responsible for the victim’s murder, the family would publicly acknowl-
    edge it. In 1994, an employee of Sutton Associates stole the firm’s files on
    the case, including detailed suspect profiles of Thomas Skakel and the
    petitioner, and gave them to Levitt and Dominick Dunne, an author, who, in
    turn, gave them to Mark Fuhrman, the former detective famous for perjurious
    testimony in the Orenthal James (O.J.) Simpson murder trial. In 1998, Fuhr-
    man published a book in which he purported to solve the long unsolved
    murder of the victim by accusing the petitioner based on one of several
    theories of the murder posited by Sutton Associates investigators and con-
    tained in the stolen files, namely, that the petitioner may have had a relation-
    ship with the victim and become jealous upon seeing her and Thomas Skakel
    ‘‘carrying on’’ in the Skakel driveway.
    7
    Although Benedict observed in closing argument, more or less in passing,
    that the jury was not required to reject the petitioner’s alibi defense in
    order to find him guilty—because the forensic evidence indicated that she
    conceivably could have been alive as late as 5:30 a.m. on October 31, 1975—
    he made no effort to explain where the victim conceivably could have been
    after 9:30 p.m. on October 30, when she was due home. Indeed, not one of
    the hundreds of persons interviewed by the police since the crime was
    committed ever saw the victim after 9:30 p.m., when she was last seen with
    Thomas Skakel. Neither did Benedict proffer a credible explanation as to
    why several people, including the victim’s mother, heard dogs barking agitat-
    edly and other unusual noises between 9:30 and 10 p.m. on October 30.
    Moreover, although Benedict asserted that the victim could have been alive
    after 10 p.m., Benedict himself acknowledged that there is no reasonable
    likelihood that the victim was alive after 1 a.m. on October 31. In any event,
    if the petitioner could have demonstrated to the satisfaction of the jury that
    he was not anywhere near the scene of the crime between 9:30 and 10 p.m.
    on October 30—indeed, if he could have raised a reasonable doubt in the
    jurors’ minds as to his whereabouts at that time—it is highly unlikely that
    he would have been found guilty of the victim’s murder.

    With respect to the factual premise of the respondent’s argument, I
    disagree with the majority’s assertion that the habeas court credited Sher-
    man’s testimony that the petitioner had not told him about Ossorio’s pres-
    ence at the Terrien residence on the evening of October 30, 1975, and
    discredited the petitioner’s contrary testimony that he had, in fact, brought
    that fact to Sherman’s attention. The habeas court made no such finding,
    explaining, instead, that it made no difference whether the petitioner had
    informed Sherman about Ossorio because Sherman was on notice, by virtue
    of Dowdle’s grand jury testimony, that her ‘‘beau’’ was, in fact, at the Terrien
    residence. In essence, the habeas court simply assumed that the petitioner
    had not told Sherman about Ossorio and then proceeded to explain why
    Dowdle’s grand jury testimony was more than sufficient to place Sherman
    on notice of Ossorio as a potential independent alibi witness. I fully agree
    with the habeas court that, in light of Dowdle’s grand jury testimony, it
    matters not whether the petitioner told Sherman about Ossorio. If, however,
    it truly matters to the majority, I would urge the majority to obtain an
    articulation from the habeas court on this issue because I firmly believe
    that the majority is mistaken in its reading of the habeas court’s decision.
    Because, however, the majority proceeds on the premise that the petitioner
    did not apprise Sherman about Ossorio, and because it makes no difference
    for purposes of my analysis, I assume that such was the case.
    10
    The majority makes much of the fact that, according to Sherman’s
    testimony at the habeas trial, none of the petitioner’s alibi witnesses ever
    told him that Ossorio or anyone else was present at the Terrien home on
    the evening of October 30, 1975. The majority’s reliance on this testimony
    is misplaced. First, the habeas court never made any findings with respect
    to the credibility of that testimony, and so the majority has no basis to treat
    it as accurate. Second, the issue is not whether the witnesses volunteered
    information about Ossorio to Sherman because, as I have explained, there
    are many reasons why they would not have known that Ossorio was a
    potentially important witness. Indeed, the fact that Dowdle was unaware
    of Ossorio’s importance is reflected in her matter-of-fact grand jury and
    trial testimony about Ossorio. Third, Sherman was questioned at the habeas
    trial whether he had asked the family alibi witnesses about the presence of
    anyone else at the Terrien residence on the evening of October 30. With
    respect to Rushton Skakel, Jr., and John Skakel, Sherman could say only,
    ‘‘[p]robably.’’ When asked the same question about Terrien and Dowdle,
    Sherman answered, ‘‘I would assume I did.’’ In fact, Sherman’s ‘‘assum[p-
    tion]’’ that he had questioned Dowdle on the issue was patently incorrect:
    the habeas court expressly found that, if Sherman had asked Dowdle about
    her ‘‘beau,’’ she would have identified him as Ossorio. Sherman, however,
    never did inquire about Dowdle’s beau.
    11
    The majority tries to distinguish Rompilla from the present case on
    the ground that Rompilla did not involve an alibi defense. The majority’s
    argument presents a classic example of a distinction without a difference.
    The fact that Rompilla is not an alibi case is completely irrelevant, and the
    majority provides no explanation for its contrary assertion. Rompilla is
    highly relevant to the present case because it underscores the fact that
    counsel has an obligation to make reasonable inquiry into facts in mitigation
    or other red flags when reviewing discovery materials, even when those
    facts or red flags are unexpected. Dowdle’s testimony concerning her ‘‘beau’’
    is precisely the kind of red flag that competent counsel would have recog-
    nized and pursued further.
    12
    Ease of access, rather than whether the petitioner supplied the name
    of the witness, was the focus of the court’s analysis in Gaines. Given our
    previous recognition that counsel may be required to investigate leads not
    supplied by a client; see Siemon v. Stoughton, 
    184 Conn. 547
    , 557, 
    440 A.2d 210
     (1981) (counsel was ineffective for failing to interview witnesses of
    related incidents presented by investigator); whether a name was supplied
    is simply irrelevant. In both Gaines and the present case, counsel made a
    conscious decision not to investigate an identifiable witness whose testi-
    mony might well have been helpful.
    13
    To do otherwise when reviewing testimony pertaining directly to the
    petitioner’s alibi in a case relying largely on an alibi defense would itself
    clearly amount to ineffective assistance of counsel, and the majority does
    not contend otherwise. On the contrary, the majority sets forth the reasons
    why, in its view, Sherman’s conscious decision not to pursue the Ossorio
    lead was reasonable.
    14
    I again underscore the minimal effort that would have been required
    of Sherman to locate Ossorio, as well as the potentially great reward of a
    disinterested alibi witness. See, e.g., Montgomery v. Petersen, 
    supra,
     
    846 F.2d 413
     (counsel was ineffective by failing to track down ‘‘extraordinarily
    significant’’ testimony of single disinterested alibi witness in case). By way
    of analogy, we are not asking Sherman to waste his time panning for gold
    on a miner’s chance of striking it rich. We are simply asking him to check
    the number on his bingo card to see if it matches the winning draw. Whereas
    the former might reasonably be characterized as a fool’s errand, the failure
    to do the latter is neither rational nor reasonable.
    15
    Moreover, as the Third Circuit has explained, incomplete knowledge of
    a witness’ name does not render the witness unidentifiable. See Gregg v.
    Rockview, supra, 
    596 Fed. Appx. 77
     (counsel acted unreasonably in failing
    to ascertain identity of alibi witness merely referenced by petitioner as
    ‘‘Weezy’’).
    16
    Toccaline v. Commissioner of Correction, 
    80 Conn. App. 792
    , 
    837 A.2d 849
    , cert. denied, 
    268 Conn. 907

    , 
    125 S. Ct. 301
    , 
    160 L. Ed. 2d 90
     (2004), which
    the majority also cites for the proposition that counsel’s representation is
    not deficient when he fails to investigate witnesses not mentioned by the
    client, is similarly inapposite. In that case, although the habeas court was
    presented with the testimony of the missing witness, there was nothing to
    indicate that the witness was identifiable by counsel at the time of trial.
    Instead, the habeas court suggested that counsel might have discovered the
    witness with a properly attuned line of questioning, a suggestion that the
    Appellate Court reasonably rejected. See 
    id.,
     816–17. Such a fact pattern
    is entirely distinct from one involving the failure to investigate a readily
    identifiable witness, as in the present case.
    17
    As the majority explains, to put forth a third-party culpability defense,
    the defendant ‘‘must . . . present evidence that directly connects a third
    party to the crime with which the defendant has been charged. . . . 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.’’ (Citations omitted;
    internal quotation marks omitted.) State v. Hernandez, 
    224 Conn. 196
    , 202,
    
    618 A.2d 494
     (1992). Third-party culpability evidence is admissible, therefore,
    when the evidence is sufficient to give rise to a reasonable doubt about the
    defendant’s guilt. See, e.g., State v. Baltas, 
    311 Conn. 786
    , 810–11, 
    91 A.3d 384
     (2014).
    18
    The majority intimates that Sherman was unaware of the futility of a
    third-party culpability defense predicated on Littleton’s commission of the
    murder, observing that the habeas court made no finding that Sherman was
    aware before the petitioner’s criminal trial that the core of his third-party
    culpability defense against Littleton—Littleton’s purported admissions—
    was the result of a ruse that had been played on him by state and local
    investigators. No such finding was required, however, because the record
    establishes that Sherman was made aware of this fact by the state’s pretrial
    motion to preclude him from raising a third-party culpability defense against
    Littleton on the ground that there was no evidence connecting Littleton to
    the murder.
    19
    In light of the complete absence of evidence suggesting that Littleton
    had played a role in the victim’s murder, it is difficult to understand why
    the trial court permitted Sherman to raise a third-party culpability defense
    predicated on Littleton’s commission of the murder. Perhaps it is because
    before the Littleton evidence actually was presented in open court to the
    jury, it appeared to the court that Littleton might have made some potentially
    incriminating statements to Baker or Morall. As the real story emerged,
    however, it became crystal clear that Littleton never did any such thing. By
    that point, of course, Sherman was stuck with his ill-advised decision to
    present the Littleton third-party culpability defense.
    20
    Sherman also sought to implicate Littleton on the basis of certain addi-
    tional facts, but none of these facts would have created the slightest doubt
    in the minds of the jurors as to the wisdom of the state’s decision to grant
    Littleton immunity from prosecution. Indeed, none of them even connected
    Littleton to the murder. For example, the majority states that Sherman
    presented the testimony of state criminalist, Henry Lee, that ‘‘two hairs
    found at the crime scene were microscopically similar to head hairs from
    Littleton.’’ Contrary to the majority’s assertion, however, the hairs in question
    were not found at the crime scene but, rather, on sheets that were brought
    to the crime scene, by responding officers, who used them to cover the
    victim’s body for transport to the morgue. As a result, it could not be
    determined whether the hairs were present during the commission of the
    crime or whether they were brought to the crime scene with the sheets.
    Sherman was also aware before the petitioner’s criminal trial that mitochon-
    drial DNA testing of one of the hairs had conclusively eliminated Littleton
    as the source of that hair. Although insufficient DNA material was obtained
    from the second hair to permit similar testing, all of the trial experts agreed
    that the hair showed both similarities and dissimilarities to Littleton’s hair
    such that the most that could be gleaned from a comparison of the two
    was that Littleton could not be excluded from the class of potential donors.
    Sherman also introduced evidence of Littleton’s erratic behavior in the
    years following the murder, the apparent result of alcoholism and an
    untreated bipolar disorder. But he utterly failed to present an intelligible
    connection between that behavior, which occurred many years after the
    murder, and any possible involvement by Littleton in the murder. In one
    incident, for example, which took place in the 1990s, Littleton was arrested
    for drunk and disorderly conduct after climbing a tower in Florida and
    delivering President John F. Kennedy’s ‘‘Iich bin ein Berliner’’ speech. During
    his arrest, Littleton identified himself as ‘‘Kenny Kennedy, the black sheep
    of the Kennedy family.’’ On the basis of this evidence, Sherman argued
    that Littleton once identified himself as ‘‘Kenny Kennedy because [John F.
    Kennedy] was his hero. He painted himself as the black sheep of the Kennedy
    family. How does that figure in here? I don’t know.’’ It is unlikely the jury
    knew either. The majority also notes that Sherman, in the petitioner’s pretrial
    motion for permission to present a third-party culpability defense, indicated
    that he ‘‘planned to show that Littleton had lied to the police in his initial
    statement about his activities on the night [of the victim’s murder] . . . and
    later had changed his account about his activities that night on several
    occasions.’’ Sherman appeared to abandon this argument at the petitioner’s
    criminal trial, however, as there is no mention of it in his closing argument;
    nor does there appear to be any evidence to support it.
    21
    The Skakel family chauffeur, Franz Wittine, reported to the police that,
    ‘‘on several occasions he observed Thomas [Skakel] leave his house to take
    a walk, carrying a golf club. He also reported that he had observed Thomas
    [Skakel] in outbreaks of rage.’’ Another witness, ‘‘Jackie Wetenhall, one of
    [the victim’s] close friends . . . observed Thomas [Skakel] . . . walking
    . . . at night, carrying a golf club.’’
    22
    Joseph Jachimczyk, a physician and then Chief Medical Examiner for
    Harris County, Texas, assisted the Greenwich police in their investigation
    and determined that the time of the victim’s death was 10 p.m., which
    determination was based, in part, on the contents of her stomach and the
    extent of rigor mortis that had set in by the time her body was discovered.
    Harold Wayne Carver II, the state Chief Medical Examiner in 2002, testified
    that, although the victim could have died as late as 5:30 a.m. on October
    31, 1975, in his opinion, she died ‘‘closer to 9:30 p.m.’’ on October 30.
    23
    The record establishes that, at approximately 9:45 p.m., a dog belonging
    to the Ix family became extremely agitated at the foot of the family’s drive-
    way, directly across the street from the entrance to the victim’s driveway.
    It was later determined, on the basis of blood spatter found at the scene,
    that the victim was initially assaulted at that location. Ix reported to the
    police that, when she returned from the Skakel driveway at 9:30 p.m., she
    immediately telephoned a friend. Ix reported that, while she was talking on
    the telephone, at approximately 9:45 p.m., her dog began to bark incessantly
    and ‘‘violently’’ in the direction of the victim’s driveway. Ix went outside to
    call the dog, but the dog refused to come even though it always came when
    she called him. Ix testified that the dog ‘‘was kind of frozen in the road like
    he didn’t [want to] go any closer,’’ and that she had never seen him so
    ‘‘scared’’ or agitated. After about twenty or twenty-five minutes of constant
    barking, the family’s housekeeper had to go out and force the dog inside.
    Another of the victim’s neighbors, Robert Bjork, reported that, although he
    did not appreciate the significance of his dog’s behavior at the time, he
    observed his dog, at approximately 10 p.m., run back and forth between
    where the victim’s blood was found on the driveway and the tree where
    the victim’s body was discovered.
    24
    One might think that Thomas Skakel’s admissions, or statements against
    penal interest, would have been admissible through a witness from Sutton
    Associates. Issues relating to the attorney-client and work product privileges,
    however, ultimately prevented any such use of the Sutton Report or its
    authors.
    25
    Throne testified that he was ‘‘fresh out of law school,’’ with no prior
    experience in the area of criminal law, when Sherman hired him to work
    on the petitioner’s case. Sherman’s son, Mark Sherman, was second chair.
    26
    I also note that Sherman did not request a jury instruction on the
    petitioner’s third-party culpability defense, and the trial court did not give
    one. Nor did Sherman undertake to explain the legal significance of the
    defense in closing argument. As this court determined in State v. Arroyo,
    
    284 Conn. 597
    , 609, 
    935 A.2d 975
     (2007), a defendant is entitled to an instruc-
    tion on a third-party culpability defense if requested. Perhaps because Arroyo
    was decided after the petitioner’s criminal trial, the petitioner has not
    claimed that Sherman’s representation was ineffective insofar as he failed
    to request such an instruction. However, whether the jury fully understood
    that the state bore the burden of rebutting the defense beyond a reasonable
    doubt—and that it was not the petitioner’s burden to establish Littleton’s
    guilt—is not clear. In any event, the fact that the Littleton third-party culpabil-
    ity defense had no basis in fact doomed it from the very start; under the
    circumstances, Sherman’s failure to apprise the jury of its legal import
    was inconsequential.
    27
    The petitioner was sent to Elan School, an alcohol and drug rehabilita-
    tion facility for troubled adolescents in Poland, Maine, in 1978, as part of
    a plea agreement after the petitioner was charged with driving under the
    influence in New York.
    28
    The majority also relies on Fuhrman’s book to support its conclusion
    that Sherman reasonably could have decided to forgo implicating Thomas
    Skakel out of fear that it might bolster the state’s theory as to the petitioner’s
    motive. See footnote 18 of the majority opinion. Such reliance only reflects
    the thin reed on which the majority’s argument rests.
    29
    It is unfortunate that the majority has seen fit to rely on Fuhrman’s
    speculative account of a relationship between the victim and the petitioner
    as a basis for reversing the habeas court’s judgment. Although the possibility
    of such a relationship was one of several theories posited by the Sutton
    investigators in the mid-1990s, no credible evidence was adduced at the
    petitioner’s 2002 criminal trial in furtherance of it.
    30
    The aspect of the case identified by the habeas court pertains to State’s
    Attorney Benedict’s argument at trial that the petitioner was sent to Elan
    School as part of the Skakel family’s broader cover-up to hide him from
    the police, who were kept in the dark regarding his whereabouts. This
    contention is belied by police investigative reports, which make clear that
    the police knew full well that the petitioner was at Elan School and had
    been in direct contact with the school. This point is important because
    Benedict also argued at trial that administrators at Elan School, who repeat-
    edly accused the petitioner of having murdered the victim, learned of the
    petitioner’s involvement in the murder from the petitioner’s own family,
    and not from the police.
