    MARQUIS JONES v. COMMISSIONER
    OF CORRECTION
    (AC 43862)
    Alvord, Moll and Vertefeuille, Js.
    Syllabus
    The petitioner, who had been convicted, following a jury trial, of felony
    murder, sought a writ of habeas corpus, claiming that his trial counsel,
    J, had provided ineffective assistance and that his rights to due process
    and to a fair trial had been violated by the prosecutor’s failure to disclose
    material evidence that was favorable to the defense. Following a hearing,
    the habeas court denied the petition. Thereafter, the habeas court denied
    the petition for certification to appeal, and the petitioner appealed to
    this court. Held that the habeas court did not abuse its discretion in
    denying the petition for certification to appeal, the petitioner having
    failed to demonstrate that his claims involved issues that were debatable
    among jurists of reason, that a court could resolve the issues in a
    different manner or that the questions raised were adequate to deserve
    encouragement to proceed further: this court declined to review the
    petitioner’s claim that the habeas court deprived him of his statutory
    and constitutional rights in failing to admit into evidence or to consider
    the transcript of his underlying criminal trial, as the petitioner did not
    raise any claims relating to the habeas court’s treatment of the criminal
    trial transcript in his petition for certification to appeal; moreover, based
    on the underlying facts as found by the habeas court, this court con-
    cluded that the habeas court properly found that the petitioner failed
    to establish that J rendered ineffective assistance, as that court correctly
    determined that the petitioner failed to establish prejudice on the basis
    of J’s failure to explore the condition of the victim’s body when cross-
    examining the state’s main witness, B, as the petitioner failed to present
    B as a witness at the habeas trial, or on the basis of J’s failure to consult
    and call as a witness a forensic expert as, although the petitioner asserted
    that an expert could have provided important information to his counsel,
    he failed to state how such information would have impacted the case,
    or on the basis of J’s failure to follow up on bloodstains found in the
    victim’s car, the petitioner having failed to link the victim’s car and the
    bloodstains in it to the murder, and this court declined to review the
    petitioner’s claim that J failed to follow up on the handling of the
    victim’s car by the police, as the claim was not distinctly raised before
    or addressed by the habeas court; furthermore, this court concluded
    that the habeas court properly determined that there was no violation
    of Brady v. Maryland (
    373 U.S. 83
    ), because, although the prosecutor
    failed to disclose to the petitioner that DNA evidence obtained from
    bloodstains in the victim’s car generated a match to a convicted offender,
    the petitioner failed to establish a connection between the murder and
    those bloodstains and thus failed to show that evidence of that match
    was material to his defense.

    Opinion
    ALVORD, J. The petitioner, Marquis Jones, appeals
    following the denial of his petition for certification to
    appeal from the judgment of the habeas court denying
    his petition for a writ of habeas corpus. On appeal, the
    petitioner claims that the habeas court (1) abused its
    discretion in denying his petition for certification to
    appeal, (2) deprived him of his constitutional and statu-
    tory rights by failing to admit into evidence or consider
    the transcripts of the underlying criminal trial, (3)
    improperly concluded that his trial counsel did not pro-
    vide ineffective assistance, and (4) improperly con-
    cluded that there were no violations of Brady v. Mary-
    land, 
    373 U.S. 83
    , 
    83 S. Ct. 1194
    , 
    10 L. Ed. 2d 215
     (1963),
    at his underlying criminal trial. We conclude that the
    habeas court did not abuse its discretion in denying
    the petitioner’s petition for certification to appeal and,
    therefore, dismiss the appeal.
    This court set forth the following facts, which the
    jury reasonably could have found, in the petitioner’s
    direct appeal from his conviction. ‘‘On the evening of
    December 26, 2002, the eighteen year old victim, accom-
    panied by his cousin, Sam Moore, attended a party at
    a club in Bridgeport. The [petitioner] was at the club
    at the same time as the victim and Moore. After leaving
    the club, the victim and Moore went to a nearby restau-
    rant. The [petitioner], who was armed with a gun,
    arrived at the same restaurant at approximately 1 a.m.
    While there, the [petitioner] learned that the victim and
    Moore were interested in purchasing marijuana. The
    [petitioner] told an acquaintance, Gary Browning, that
    the victim and Moore had money and that he wanted
    to rob them. Browning arranged to sell marijuana to
    the victim and led him to a nearby backyard to complete
    the sale. Thereafter, the [petitioner] approached the
    victim from behind and stated: ‘You know what time it
    is, run that shit.’ As Browning walked away from the
    victim, the [petitioner] shot the victim in the back of
    the head and took money and drugs from him. The
    gunshot caused the victim’s death. The victim’s body
    was found on the snow coated ground the next morn-
    ing.’’ (Footnote omitted.) State v. Jones,

    The petitioner was arrested on June 4, 2008. On May
    28, 2010, following a jury trial, the petitioner was con-
    victed of felony murder. He was sentenced to a total
    effective sentence of forty years of incarceration. Fol-
    lowing a direct appeal, the judgment of conviction was
    affirmed by this court. 
    Id., 790
    .
    The present habeas proceeding was commenced in
    May, 2013, and, on May 10, 2019, the petitioner filed a
    three count, third amended petition for a writ of habeas
    corpus. The first count included a number of claims of
    ineffective assistance of counsel, three of which are at
    issue in this appeal. The second and third counts each
    alleged that his rights to due process and a fair trial
    were violated by the prosecutor’s failure to disclose
    material evidence that was favorable to the defense. A
    trial was held over the course of two days, on August
    27, 2018, and June 4, 2019. On November 26, 2019, the
    habeas court, Newson, J., issued a memorandum of
    decision in which it denied the petitioner’s habeas peti-
    tion.
    The petitioner subsequently filed a petition for certifi-
    cation to appeal, which the court also denied. This
    appeal followed. Additional facts and procedure will
    be set forth as necessary.
    I
    The petitioner first claims that the habeas court
    abused its discretion in denying his petition for certifica-
    tion to appeal from the court’s judgment denying his
    petition for a writ of habeas corpus. We disagree.
    General Statutes § 52-470 (g) provides: ‘‘No appeal
    from the judgment rendered in a habeas corpus pro-
    ceeding brought by or on behalf of a person who has
    been convicted of a crime in order to obtain such per-
    son’s release may be taken unless the appellant, within
    ten days after the case is decided, petitions the judge
    before whom the case was tried or, if such judge is
    unavailable, a judge of the Superior Court designated
    by the Chief Court Administrator, to certify that a ques-
    tion is involved in the decision which ought to be
    reviewed by the court having jurisdiction and the judge
    so certifies.’’
    ‘‘As our Supreme Court has explained, one of the
    goals our legislature intended by enacting this statute
    was to limit the number of appeals filed in criminal
    cases and hasten the final conclusion of the criminal
    justice process . . . . [T]he legislature intended to dis-
    courage frivolous habeas appeals. . . . [Section] 52-
    470 [g] acts as a limitation on the scope of review, and
    not the jurisdiction, of the appellate tribunal. . . .
    ‘‘Faced with a habeas court’s denial of a petition for
    certification to appeal, a petitioner can obtain appellate
    review of the [disposition] of his [or her] petition for
    habeas corpus only by satisfying the two-pronged test
    enunciated by our Supreme Court in Simms v. Warden,
    
    229 Conn. 178
    , 
    640 A.2d 601
     (1994), and adopted in
    Simms v. Warden, 
    230 Conn. 608
    , 612, 
    646 A.2d 126
    (1994). First, he [or she] must demonstrate that the
    denial of his [or her] petition for certification consti-
    tuted an abuse of discretion. . . . Second, if the peti-
    tioner can show an abuse of discretion, he [or she] must
    then prove that the decision of the habeas court should
    be reversed on its merits. . . .
    ‘‘To prove an abuse of discretion, the petitioner must
    demonstrate that the [resolution of the underlying claim
    involves issues that] are debatable among jurists of
    reason; that a court could resolve the issues [in a differ-
    ent manner]; or that the questions are adequate to
    deserve encouragement to proceed further. . . .
    ‘‘In determining whether the habeas court abused
    its discretion in denying the petitioner’s request for
    certification, we necessarily must consider the merits of
    the petitioner’s underlying claims to determine whether
    the habeas court reasonably determined that the peti-
    tioner’s appeal was frivolous. In other words, we review
    the petitioner’s substantive claims for the purpose of
    ascertaining whether those claims satisfy one or more
    of the three criteria . . . adopted by [our Supreme
    Court] for determining the propriety of the habeas
    court’s denial of the petition for certification.’’ (Foot-
    note omitted; internal quotation marks omitted.) Whist-
    nant v. Commissioner of Correction, 
    199 Conn. App. 406
    , 414–15,

    , cert. denied, 
    335 Conn. 969
    ,
    
    240 A.3d 286
     (2020).
    For the reasons set forth in parts II, III, and IV of
    this opinion, we conclude that the petitioner has failed
    to demonstrate that his claims are debatable among
    jurists of reason, a court could resolve the issues in a
    different manner, or the questions are adequate to
    deserve encouragement to proceed further. Thus, we
    conclude that the habeas court did not abuse its discre-
    tion in denying the petition for certification to appeal.
    II
    Turning to the merits of the petitioner’s first substan-
    tive claim, the petitioner claims that the habeas court
    deprived him of ‘‘his constitutional and statutory rights
    to the opportunity to be heard’’ by failing to admit into
    evidence or consider the transcript of the underlying
    criminal trial. The respondent, the Commissioner of
    Correction, contends, inter alia, that this claim is not
    reviewable. We agree with the respondent.
    The following additional procedural history is rele-
    vant to our resolution of this claim. On the first day of
    the habeas trial, August 27, 2018, the petitioner’s habeas
    counsel offered the underlying criminal trial transcript
    as a full exhibit, and the respondent’s attorney objected,
    noting that the transcript, which was saved on a flash
    drive, did not appear to be certified and the paper copy
    offered by the petitioner had notes on it. The respon-
    dent’s attorney told the court that if there was a brief
    recess she would be able to review the flash drive to
    determine whether the transcript was certified. The
    court advised the parties that it planned a lunch recess
    to afford them review time. One of the attorneys, how-
    ever, had to attend another hearing in the afternoon;
    therefore, the trial was adjourned without a resolution
    of the transcript issue. On June 4, 2019, the second,
    and last, day of the trial, the petitioner’s habeas counsel
    ‘‘offer[ed] the expanded record pursuant to . . . Prac-
    tice Book § 23-36,1 including the transcripts of the crimi-
    nal case’’; (footnote added); and the court stated that
    it would accept the transcripts as part of the ‘‘underlying
    record.’’2 In the court’s memorandum of decision deny-
    ing the petition for a writ of habeas corpus, the court
    noted that, ‘‘[s]trangely, although submitted as an ID
    exhibit . . . the transcript from the underlying crimi-
    nal trial was never offered as a full exhibit at the habeas
    trial’’ and further noted that the transcript ‘‘likely could
    have offered some clarification about exactly what hap-
    pened.’’
    On December 10, 2019, after the habeas court denied
    his petition for a writ of habeas corpus, the petitioner
    filed a petition for certification to appeal. Although the
    petitioner set forth numerous grounds on which he
    proposed to appeal, he did not in any way implicate
    the court’s treatment of the criminal trial transcript.
    The court denied the petition for certification to appeal
    on December 11, 2019. On January 28, 2020, the peti-
    tioner appealed to this court. On March 4, 2020, the
    petitioner filed a motion for articulation and a motion
    for rectification of appeal, arguing therein that the
    ‘‘habeas court erroneously determined that the underly-
    ing transcript of the criminal trial was not in evidence
    and, therefore, [the court] failed to consider the tran-
    script [in] making its decision.’’ On May 29, 2020, the
    habeas court denied these motions, noting that ‘‘the
    criminal transcript was not a full exhibit.’’ On August
    6, 2020, the petitioner filed with this court two motions
    for review with respect to the habeas court’s decisions
    on those motions. This court granted the motion to
    review the decision on the petitioner’s motion for articu-
    lation and ordered the habeas court to articulate
    whether it considered any portion of the criminal trial
    transcript when rendering its decision. The habeas
    court, in its responsive articulation, explained that ‘‘the
    petitioner never entered the criminal trial transcript as
    a full exhibit. Since the transcripts remained an exhibit
    for ID only . . . [the court] would not have considered
    the exhibit in rendering the memorandum of decision
    following the trial. To the extent the parties referenced
    said transcript in their briefs, the court simply accepted
    those as arguments of the parties based on the evidence
    and full exhibits that were submitted at trial.’’ At no
    point did the petitioner seek to amend his petition for
    certification to appeal to include arguments related to
    the court’s treatment of the criminal trial transcript.
    Now, on appeal, the petitioner claims that, because
    ‘‘[t]he underlying transcript was offered by counsel for
    the petitioner, was not objected to by the respondent’s
    counsel, and was relied on both in questioning wit-
    nesses during the habeas trial and in the posttrial briefs
    of the parties,’’ the court’s ‘‘[f]ailure to admit the tran-
    script denied [the petitioner] . . . his due process right
    to a meaningful opportunity to be heard. And, failure
    to consider any portion of the underlying criminal tran-
    script also denied [the petitioner] his due process rights
    to be heard.’’ In response, the respondent argues that,
    inter alia, this claim is not reviewable because ‘‘it was
    not raised as a ground of error in the petition for certifi-
    cation to appeal.’’
    ‘‘As our standard of review set forth [in part I of this
    opinion] makes clear, an appeal following the denial of
    a petition for certification to appeal from the judgment
    denying a petition for a writ of habeas corpus is not the
    appellate equivalent of a direct appeal from a criminal
    conviction. Our limited task as a reviewing court is to
    determine whether the habeas court abused its discre-
    tion in concluding that the petitioner’s appeal is frivo-
    lous. Thus, we review whether the issues for which
    certification to appeal was sought are debatable among
    jurists of reason, a court could resolve the issues differ-
    ently or the issues are adequate to deserve encourage-
    ment to proceed further. . . . Because it is impossible
    to review an exercise of discretion that did not occur,
    we are confined to reviewing only those issues which
    were brought to the habeas court’s attention in the
    petition for certification to appeal.’’ (Citation omitted.)

    ,

     (2021).
    Further, ‘‘[i]t is well established that a petitioner can-
    not demonstrate that the habeas court abused its discre-
    tion in denying a petition for certification to appeal if
    the issue raised on appeal was never raised before the
    court at the time that it considered the petition for
    certification to appeal as a ground on which certifica-
    tion should be granted.’’ (Internal quotation marks omit-
    ted.) Whistnant v. Commissioner of Correction, supra,
    
    199 Conn. App. 416
    .
    In the present case, the petitioner did not raise any
    claims related to the court’s treatment of the trial tran-
    script in his petition for certification to appeal. He
    explains that ‘‘[t]he issue was raised and addressed in
    the posttrial motions for articulation and rectification
    and in the motions for review of the decisions on these
    motions,’’ which provided the court with ‘‘the opportu-
    nity to address this claim.’’ The petitioner asserts that
    the claim is reviewable because ‘‘[t]he court was given
    the opportunity to address this issue through the
    motions . . . .’’ These arguments, however, ignore the
    statutory nature of habeas appeals. ‘‘Section 52-470 (g)
    conscribes our appellate review to the issues presented
    in the petition for certification to appeal . . . .’’ Whist-
    nant v. Commissioner of Correction, supra, 
    199 Conn. App. 418
    . The petitioner’s contentions are unavailing,
    and he cannot demonstrate that the habeas court
    abused its discretion in denying the petition for certifi-
    cation to appeal on this ground.
    III
    The petitioner’s second substantive claim on appeal
    is that the court erroneously concluded that he failed
    to establish that his trial counsel, Attorney Jeffrey Beck,
    rendered ineffective assistance. Specifically, the peti-
    tioner claims that his trial counsel failed (1) to attack
    Browning’s testimony with respect to the condition of
    the victim’s body, (2) to hire a forensic expert, and (3)
    to conduct a timely and thorough investigation of the
    case and asserts that, ‘‘if [defense counsel] had not
    failed to take the actions discussed herein, it is probable
    that the outcome would have been different.’’ We dis-
    agree.
    ‘‘[As it relates to the petitioner’s substantive claims]
    [o]ur standard of review of a habeas court’s judgment on
    ineffective assistance of counsel claims is well settled.’’

    324 Conn. 908
    , 
    152 A.3d 1246
     (2017). ‘‘In a habeas appeal, this court cannot
    disturb the underlying facts found by the habeas court
    unless they are clearly erroneous, but our review of
    whether the facts as found by the habeas court consti-
    tuted a violation of the petitioner’s constitutional right
    to effective assistance of counsel is plenary. . . .
    ‘‘In Strickland v. Washington, [
    466 U.S. 668
    , 687, 
    104 S. Ct. 2052
    , 
    80 L. Ed. 2d 674
     (1984)], the United States
    Supreme Court established that for a petitioner to pre-
    vail on a claim of ineffective assistance of counsel, he
    must show that counsel’s assistance was so defective
    as to require reversal of [the] conviction . . . . That
    requires the petitioner to show (1) that counsel’s perfor-
    mance was deficient and (2) that the deficient perfor-
    mance prejudiced the defense. . . . Because both
    prongs . . . must be established for a habeas peti-
    tioner to prevail, a court may dismiss a petitioner’s
    claim if he fails to meet either prong. . . . With respect
    to the prejudice component of the Strickland test, the
    petitioner must demonstrate that counsel’s errors were
    so serious as to deprive the [petitioner] of a fair trial,
    a trial whose result is reliable. . . . It is not enough
    for the [petitioner] to show that the errors had some
    conceivable effect on the outcome of the proceedings.
    . . . Rather, [t]he [petitioner] must show that there is
    a reasonable probability that, but for counsel’s unpro-
    fessional errors, the result of the proceeding would have
    been different. A reasonable probability is a probability
    sufficient to undermine confidence in the outcome.’’

    200 Conn. App. 617
    .
    A
    We first address the petitioner’s contention that his
    trial counsel failed to explore the condition of the vic-
    tim’s body when cross-examining Browning, the state’s
    main witness against the petitioner in the criminal trial.
    The following additional procedural history is rele-
    vant to our resolution of this claim. At the habeas trial,
    the exhibits from the criminal trial, which included pic-
    tures of the crime scene and the victim, were entered
    as full exhibits. The pictures show the victim lying face
    down in the snow, with clothing partially removed, and
    surrounded with footprints. In addition, Joette Devan,
    a detective who responded to the crime scene, testified
    that the victim was lying face down and that there were
    footprints in the snow around the body. The petitioner
    also presented evidence, in the form of expert testi-
    mony, that the position of the victim’s body indicated
    that it had been moved after the murder occurred.3
    The petitioner presented expert testimony of Attor-
    ney John Watson. When Watson was asked about the
    footprints around the victim’s body, he testified that
    ‘‘[s]ome of [the footprints] were identified as those of
    Mr. Browning because of the footwear he himself said
    he was wearing, and some were identified as those of
    the victim because they matched the type of footwear
    the victim was wearing.’’ The petitioner’s habeas coun-
    sel then asked, ‘‘[I]f you as a defense attorney . . .
    have a crime scene where the victim has been rolled
    and his clothes have been pulled off him . . . to some
    degree, what would you do with that?’’ Watson
    responded, ‘‘I think that’s something that the forensic
    expert could help defense counsel to bring to the jury’s
    attention through cross-examination of the state’s wit-
    nesses that the footprints around the body were those
    of Mr. Browning. So, it’s a reasonable inference that,
    in fact, he was the person who tampered with the body
    after the shooting.’’
    The petitioner’s trial counsel also testified at the
    habeas trial. The case was scheduled for trial at the
    time when trial counsel was appointed to represent the
    petitioner. He testified that his defense theory was ‘‘that
    [the petitioner] had nothing to do with the incident at
    all, wasn’t present when [the victim] was shot, and
    wasn’t aware of what was going on.’’ He further testified
    that his approach in cross-examining Browning was to
    attack Browning’s testimony because, according to trial
    counsel, ‘‘[Browning’s] testimony . . . was very weak’’
    and ‘‘very incredulous.’’ The petitioner’s trial counsel
    testified further that he questioned Browning about
    footprints found around the body and that Browning
    admitted that the footprints were his own. Trial counsel
    recalled that, in his closing argument at trial, he men-
    tioned that the victim’s body may have been moved after
    the shooting. Further, on inquiry from the respondent’s
    counsel, trial counsel agreed that pursuing a line of
    questioning as to what may have happened to the vic-
    tim’s body after the shooting would not have been rele-
    vant to the defense that the petitioner was not at the
    scene and had nothing to do with the murder. Finally,
    trial counsel conceded that the state never claimed that
    the petitioner’s footprints were at the scene of the
    crime. The petitioner never called Browning as a wit-
    ness at the habeas trial.
    In denying the petitioner’s amended petition for a
    writ of habeas corpus, the habeas court concluded that
    the petitioner’s failure to present Browning as a witness
    at the habeas trial was fatal to his claim, citing Nieves
    v. Commissioner of Correction, 
    51 Conn. App. 615
    ,
    623–24, 
    724 A.2d 508
    , cert. denied, 
    248 Conn. 905
    , 
    731 A.2d 309
     (1999), which held that ‘‘[t]he failure of the
    petitioner to offer evidence as to what [the witnesses]
    would have testified is fatal to his claim,’’ as, without
    the evidence, the court was ‘‘unable to conclude that
    he was prejudiced.’’
    On appeal, the petitioner asserts that ‘‘[a] review of
    the photograph of the [victim’s] body indicates that it
    ‘most likely ha[d] been moved at some point after the
    injury occurred’ ’’ and that Browning’s footprints were
    ‘‘ ‘abundant’ around the victim’s body.’’ Thus, he argues
    that, because ‘‘the state had a weak case, it is reasonably
    probable that the jury would have found reasonable
    doubt had [his trial counsel] adequately attacked [Brow-
    ning’s] testimony.’’ The respondent maintains that the
    habeas court correctly determined that prejudice could
    not be assessed given the fact that the petitioner did
    not call Browning as a witness at the habeas trial. In
    response, the petitioner asserts that, ‘‘[i]f [Browning]
    had testified at the habeas trial, his answers would not
    have changed the fact that [the petitioner’s trial counsel]
    failed to bring to the jury’s attention the discrepancies
    in [Browning’s] version of the shooting and the physical
    evidence.’’ Accordingly, it is the petitioner’s position
    that ‘‘how [Browning] would have answered is irrele-
    vant and was not required’’ because ‘‘the failure of [trial
    counsel’s] cross-examination of [Browning] was the
    failure to challenge his testimony with the physical evi-
    dence.’’ We agree with the respondent.
    ‘‘It is axiomatic that a habeas petitioner who claims
    prejudice based on counsel’s alleged failure to present
    helpful evidence from a particular witness, must call
    that witness to testify before the habeas court or other-
    wise prove what the witness would or could have stated
    had he been questioned at trial, as the petitioner claims
    he should have been.’’ Benitez v. Commissioner of Cor-
    rection,

    the complainant would or could have testified to on

    access to and possible use’’ of chemicals involved in
    underlying arson and, therefore, could not show preju-
    dice); see also Taft v. Commissioner of Correction, 
    159 Conn. App. 537
    , 554, 
    124 A.3d 1

    prove prejudice when he ‘‘did not offer evidence regard-
    ing how [the witnesses] would have testified if they had

    51 Conn. App. 623
     (petitioner’s
    failure ‘‘to offer evidence as to what [witnesses] would
    have testified is fatal to his claim’’). In order for the
    habeas court to assess the claim that the petitioner’s
    trial counsel did not properly cross-examine Browning,
    the petitioner needed to call Browning as a witness at
    the habeas trial or otherwise demonstrate how Brow-
    ning would have testified had his cross-examination
    been conducted as now suggested by the petitioner.
    Accordingly, we conclude that the habeas court prop-
    erly determined that the petitioner failed to establish
    prejudice, and, therefore, the court did not abuse its
    discretion in denying the petition for certification to
    appeal as to this claim.
    B
    The petitioner next claims that his trial counsel failed
    to consult and call as a witness a forensic expert. Specif-
    ically, in this third claim he asserts that a forensic expert
    could have (1) ‘‘told [trial counsel] that the victim’s
    body had been moved subsequent to the shooting,’’ (2)
    ‘‘testified as to the relevance and importance of the
    shoe print that was approximately [twenty] feet from
    the victim,’’ and (3) ‘‘told [trial counsel] the possible
    significance and could have testified regarding the vic-
    tim’s car with the bloodstained seats.’’ According to the
    petitioner, a forensic expert ‘‘would have bolstered the
    idea that the state’s version of what happened here is
    not trustworthy.’’ (Internal quotation marks omitted.)
    The petitioner, however, has failed to demonstrate that
    he was prejudiced by his trial counsel’s failure to con-
    sult and call a forensic expert.
    In addition to the evidence discussed in part III A
    of this opinion, the petitioner presented the following
    evidence. Devan, a detective involved in the investiga-
    tion, testified that the victim’s car keys were next to
    the victim’s body and that the victim’s car was located
    nearby. Devan testified that two of the car’s seats had
    what appeared to be bloodstains on them and that the
    car was towed to the police department for further
    investigation. The petitioner presented evidence that
    the two stains found on the car seats were human blood
    and that the police removed the bloodstained fabric
    from the vehicle for DNA testing, which occurred in
    2003 and ruled out the victim as the source of the blood.
    Michael Bourke, a forensic science examiner at the
    Department of Emergency Services and Public Protec-
    tion, testified that DNA testing on the bloodstains
    resulted in several profiles that were entered into the
    Combined DNA Index System (CODIS) database4 ‘‘in
    order to search against other forensic profiles and the
    profiles from the offenders that are included [in the
    database] in hopes of furthering the investigation.’’
    Bourke also testified that ‘‘a match was generated to a
    convicted offender in this case’’ on January 12, 2009,
    identifying ‘‘Rafail E. Ferrer’’ as having DNA in the sys-
    tem that matched the sample from the victim’s car.
    The petitioner also established that his trial counsel
    did not hire or consult a forensic expert in the present
    case, and he presented testimony from Peter Valentin,
    a lecturer at the Forensic Science Department of the
    University of New Haven, as an expert in crime scene
    forensic science. Valentin testified, on reviewing a pho-
    tograph of the victim’s body at the crime scene that
    was a full exhibit in the criminal trial, that there had
    been ‘‘some movement after the injury’’ and ‘‘the [vic-
    tim] most likely ha[d] been moved at some point after
    the injury occurred.’’5 Valentin also briefly testified
    about a shoe print containing a bloodstain that was
    approximately twenty feet from the victim. When asked
    if the shoe print was ‘‘something that would be signifi-
    cant in trying to resolve this crime,’’ Valentin responded
    that ‘‘[t]he existence of that bloodstain at such a dis-
    tance from . . . where the injury occurred strongly
    suggests relevance’’ and provided several theories as
    to how the bloodstained footprint came to be.6
    When asked about what he would have done if hired
    by the petitioner’s trial counsel, Valentin said that he
    ‘‘would have advised [trial] counsel . . . that the auto-
    mobile is a relevant item of physical evidence that needs
    to be safeguarded and searched until such time as . . .
    you can determine that there’s nothing of relevance
    inside the vehicle.’’ With respect to the bloodstains in
    the victim’s car, Valentin provided suggestions only as
    to how he would have investigated the source of the
    blood (i.e., by interviewing the person whose DNA was
    matched with one of the bloodstains).
    The habeas court determined that the petitioner failed
    to establish prejudice and provided that, ‘‘[a]lthough the
    petitioner did present the testimony of . . . Valentin
    as an expert in crime scene forensic investigation, his
    testimony was neither compelling nor enlightening. He
    was not at the scene of the crime and did not examine
    any of the actual physical evidence from the scene. He
    also did not speak directly to anyone who was present
    at the scene. In fact, from the best the court can deter-
    mine, he only reviewed photographs and reports from
    the crime scene, from which he generated opinions of
    possible alternative meanings to the evidence or alter-
    native avenues of investigation that he would have
    advised defense counsel to pursue. What was wholly
    lacking, however, were any concrete scientific or fac-
    tual findings that undermined the jury’s determination
    of guilt in this case.’’
    We agree with the habeas court’s conclusion that the
    petitioner failed to show that he was prejudiced by the
    failure of his trial counsel to consult or hire a forensic
    expert. At best, Valentin’s testimony provided thoughts
    on how he would have investigated the crime scene.
    With respect to the condition of the victim’s body,
    Valentin’s testimony merely demonstrated that the body
    may have been moved slightly, which is consistent with
    the state’s theory that Browning and the petitioner
    robbed the victim after he had been incapacitated.7 With
    respect to the bloodstained footprint, Valentin testified
    only that it might be relevant without explaining why.
    Finally, with respect to the bloodstains in the victim’s
    car, Valentin merely suggested that the car should have
    been investigated and the person whose DNA matched
    with one of the bloodstains should have been inter-
    viewed, but the petitioner did not provide any informa-
    tion concerning what evidence these two actions would
    have unearthed.8 Further, although the petitioner
    asserts that an expert could have given important infor-
    mation to his trial counsel, he failed to state how such
    information would have impacted the case. None of the
    petitioner’s evidence, especially in light of the court’s
    determination that the expert’s testimony ‘‘was neither
    compelling nor enlightening,’’ demonstrates a reason-
    able probability that, had trial counsel hired an expert,
    the outcome of the proceedings would have been differ-
    ent. See Schuler v. Commissioner of Correction, supra,
    
    200 Conn. App. 617
    .
    Accordingly, we conclude that the habeas court prop-
    erly determined that the petitioner failed to establish
    prejudice and, therefore, did not abuse its discretion
    by denying the petition for certification to appeal as to
    this claim.
    C
    The petitioner’s final claim of ineffective assistance
    is that his trial counsel failed to conduct a timely and
    thorough investigation. Specifically, the petitioner argues
    that his trial counsel should have followed up on the
    police’s ‘‘handling of the victim’s car’’ and the blood-
    stains found inside the car. We address each specific
    allegation separately.
    1
    The petitioner argues that his trial counsel should
    have investigated what happened to the victim’s car
    after it was in police custody and that, if his trial counsel
    had done so, he would have discovered relevant infor-
    mation supporting the claim of inadequate police inves-
    tigation and ‘‘thereby establish[ing] reasonable doubt.’’9
    The respondent argues, inter alia, that this claim is not
    reviewable because it was not (1) raised in the habeas
    petition, (2) addressed in the petitioner’s posttrial brief,
    and (3) addressed by the habeas court in its memoran-
    dum of decision denying the petition for a writ of habeas
    corpus. We agree with the respondent.
    In the petition for a writ of habeas corpus, the peti-
    tioner alleges that his trial counsel rendered deficient
    performance because, inter alia, ‘‘[h]e failed to conduct
    a timely and thorough investigation.’’ Although the peti-
    tioner specifically references the failure of his trial
    counsel ‘‘to follow up on the information regarding the
    bloodstain[s] on the seat[s] of the victim’s car that was
    seized by the police at the time of the crime,’’ he did
    not include any allegation that his trial counsel was
    ineffective for failing to investigate what happened to
    the car after it entered police custody. In his posttrial
    brief, the petitioner, with respect to the argument that
    his trial counsel failed to conduct a timely and thorough
    investigation, argued only that his trial counsel failed
    to ‘‘pursue information regarding the bloodstains’’ and
    failed to ‘‘pursue the issue of the blood swabbings.’’
    Unsurprisingly, the habeas court did not address any
    claim that the petitioner’s trial counsel should have
    investigated the police’s ‘‘handling of the victim’s car.’’
    ‘‘It is well settled that this court does not consider
    claims not raised in the habeas court.’’ Toles v. Commis-
    sioner of Correction, 
    113 Conn. App. 717

    raised sufficiently in the habeas court.’’ Id., 730; see also
    id. (specific claim of ineffective assistance not reviewed
    because habeas court considered only ‘‘broad allegation
    concerning [attorney’s] ‘failure to investigate’ ’’). Fur-
    ther, ‘‘[i]t is well settled that this court is not bound to
    consider any claimed error unless it appears on the
    record that the question was distinctly raised at trial
    and was ruled upon and decided by the court adversely
    to the appellant’s claim.’’ (Internal quotation marks

    (due process claim deemed abandoned because not

    In the present case, given that this particular claim
    was never distinctly raised before or addressed by the
    habeas court, we decline to review this claim.
    2
    With respect to the petitioner’s claim that his trial
    counsel ‘‘failed to follow up on information regarding
    bloodstains on the seat[s] of the victim’s vehicle that
    were seized by the police at the time of the crime,’’ the
    habeas court determined that the petitioner failed to
    make the required showing of prejudice.10 Specifically,
    the court stated: ‘‘[T]he petitioner has failed to present
    any evidence that the victim’s vehicle, or anything inside
    of it, bore any material relationship to the crime. There
    appears to be no dispute that the victim, [Browning,
    and the petitioner] drove to the scene in an unrelated
    vehicle, that the keys to the victim’s car were found
    near his body, or that the victim’s car was locked when
    the police later located it. Other than the fact that these
    two blood samples were inside the victim’s vehicle, the
    petitioner has provided no rational connection between
    them and [the victim’s] murder. Finally, while Ferrer
    was identified as the likely source of one of the blood-
    stains, the petitioner has provided no credible evidence
    establishing when that sample was deposited in the car
    or placing Ferrer even within the state of Connecticut
    at the time of the crime. Therefore, even if the court
    were to assume that counsel should have followed up
    on this line of inquiry independently, the petitioner did
    not suffer any prejudice, because the information is
    irrelevant to the case.’’ (Footnote omitted.) The court
    also emphasized that the petitioner’s own testimony at
    the habeas trial ‘‘supports the irrelevance of anything
    found inside of [the victim’s] car,’’ as the petitioner
    never mentioned the victim’s car or any unknown indi-
    vidual in his testimony about the night of the murder.
    On appeal, the petitioner argues that the bloodstains
    inside the car were relevant because the police obtained
    a warrant to inspect the car and had the bloodstains
    tested for DNA, determining that the blood was not
    the victim’s. Further, the petitioner asserts that it was
    relevant because his forensic science expert testified
    at the habeas trial that ‘‘who was in [the victim’s car]
    with [the victim], what happened there, that’s all a mat-
    ter for investigation.’’ The respondent argues that the
    petitioner cannot show prejudice because he failed to
    link the car and the bloodstains in it to the murder. We
    agree with the respondent.
    The petitioner’s argument requires us to assume that,
    because the car was within the vicinity of the murder
    and because the car had blood in it that matched with
    someone in the CODIS system, it was somehow associ-
    ated with the murder. Without more evidence, however,
    we cannot so assume. Given the habeas court’s findings,
    namely, that the victim arrived at the scene in a different
    vehicle, the keys to the vehicle were found on the vic-
    tim’s body, and the car was found locked, and given
    the fact that the petitioner presented no evidence con-
    necting Ferrer to the murder—in fact, the petitioner
    presented no evidence about Ferrer whatsoever aside
    from the ‘‘hit notification’’ that included his name—it
    would be impossible to determine that, had the petition-
    er’s trial counsel followed up on the bloodstains and
    subsequently procured the ‘‘hit notification,’’ the crimi-
    nal trial could have had a different outcome. See Holley
    v. Commissioner of Correction, 
    62 Conn. App. 170
    , 175,
    
    774 A.2d 148
     (2001) (‘‘The burden to demonstrate what
    benefit additional investigation would have revealed is
    on the petitioner. . . . [See] Nieves v. Commissioner
    of Correction, 
    [supra,
     
    51 Conn. App. 624
    ] (petitioner
    could not succeed on claim of ineffective assistance on
    basis of counsel’s failure to conduct proper investiga-
    tion in absence of showing that he was prejudiced by
    counsel’s failure to interview witnesses) . . . .’’ (Cita-
    tion omitted.)).
    Accordingly, we conclude that the habeas court prop-
    erly determined that the petitioner failed to prove that
    he was prejudiced and, therefore, did not abuse its
    discretion by denying the petition for certification to
    appeal as to this claim.
    IV
    The petitioner next claims that his rights to due pro-
    cess and to a fair trial were violated by the prosecutor’s
    failure to disclose material evidence that was favorable
    to the defense in accordance with Brady v. Maryland,
    
    supra,
     
    373 U.S. 83
    . Specifically, he claims that the state
    failed to disclose (1) exculpatory DNA evidence and
    (2) a transcript from a separate criminal proceeding
    that would have served as impeachment evidence. We
    address each of the petitioner’s claims in turn.
    A
    The petitioner first claims that the state improperly
    failed to provide the defense with ‘‘[e]vidence that another
    convicted felon’s blood was in the car of the victim’’
    in violation of Brady v. Maryland, 
    supra,
     
    373 U.S. 83
    .
    We disagree.
    At the habeas trial, Bourke, the forensic examiner,
    testified that the ‘‘hit notification,’’ which identified Fer-
    rer as a DNA match with a sample taken from one of
    the car seat bloodstains, was sent to the agencies that
    investigated and prosecuted the crime, specifically, the
    police department, the prosecutor, and the major
    crimes unit. The habeas court determined that ‘‘[t]here
    was no evidence that [the petitioner’s trial counsel] ever
    received a copy of the hit notification form or that he
    was aware of its existence.’’
    In denying the petitioner’s amended petition for a
    writ of habeas corpus, the habeas court determined that
    ‘‘the petitioner cannot establish a reasonable probabil-
    ity that this evidence would have had any impact on the
    outcome of his case or the establishment of a defense
    theory,’’ noting, ‘‘the petitioner has not established any
    reasonable connection between the bloodstains on the
    seat[s] and the victim’s murder, nor has he placed . . .
    Ferrer near the scene of the crime.’’
    On appeal, the petitioner argues that the DNA match
    was material because ‘‘the fact that another person’s
    blood was in the vehicle’’ ‘‘undermines [Browning’s]
    version of the crime,’’ but he does not elaborate on how
    this information undermines Browning’s account. The
    respondent argues that ‘‘the petitioner has failed to
    establish that the blood evidence was material,’’ as (1)
    the blood was not at the crime scene but was in the
    victim’s locked car some distance from the crime scene,
    (2) the blood was dry, (3) the victim only recently had
    purchased the car, and (4) the petitioner did not present
    testimony from Ferrer nor did he present any evidence
    linking Ferrer to the crime. We agree with the respon-
    dent.
    We first set forth the standard of review applicable
    to Brady claims. ‘‘As set forth by the United States
    Supreme Court in Brady v. Maryland, 
    supra,
     
    373 U.S. 87
    , [t]o establish a Brady violation, the [defendant] must
    show that (1) the government suppressed evidence, (2)
    the suppressed evidence was favorable to the [defen-
    dant], and (3) it was material [either to guilt or to punish-
    ment]. . . . Whether the [defendant] was deprived of
    his due process rights due to a Brady violation is a
    question of law, to which we grant plenary review.’’

    ,

     (2019).
    ‘‘Under the last Brady prong, the evidence must have
    been material to the case, such that the favorable evi-
    dence could reasonably be taken to put the whole case
    in such a different light as to undermine confidence in
    the verdict. . . . The mere possibility that the undis-
    closed information might have helped the defense or
    might have affected the outcome of the trial does not
    meet the materiality standard. . . .
    ‘‘The favorable evidence must cast the whole case in
    a different light. It is not enough for the defendant to
    show that the undisclosed evidence would have allowed
    the defense to weaken or destroy a particular prosecu-
    tion witness or item of evidence to which the undis-
    closed evidence relates.’’ State v. Rosa, 
    196 Conn. App. 480
    , 503–504, 
    230 A.3d 677
    , cert. denied, 
    335 Conn. 920
    ,
    
    231 A.3d 1169
     (2020); see id., 504, 506 (CODIS match
    with DNA found on sweatshirt was not material because
    there was no testimony that person who committed
    crime was wearing sweatshirt, ‘‘the sweatshirt was not
    found at the actual crime scene but more than half a
    block away,’’ ‘‘[t]here [wa]s no evidence to indicate how
    long the sweatshirt had been there or that it was even
    present when the police first responded to the crime
    scene,’’ there was no other evidence connecting
    sweatshirt to crime, and petitioner could not connect
    person identified in CODIS match to crime).
    In the present case, we agree with the habeas court
    that the petitioner has failed to show that the CODIS
    match was material to his defense. The car that con-
    tained the bloodstains was not found at the crime scene
    but on a nearby street. There is no evidence that the
    victim or anyone else associated with the murder was
    in or near the car that night. There is no evidence estab-
    lishing how long the car had been parked there. There
    is no indication that the victim’s murder is connected
    to the victim’s car or that the blood was left during or
    as a result of the murder—indeed, there was no evi-
    dence to suggest that the bloodstains occurred near the
    time of the murder. Further, the petitioner presented
    no evidence connecting Ferrer to the crime or the crime
    scene. Finally, as the habeas court stated, ‘‘[t]he peti-
    tioner’s own testimony at the habeas trial supports the
    irrelevance of anything found inside of [the victim’s]
    vehicle. . . . Nowhere in his testimony did the peti-
    tioner reference anything to do with the [victim’s] vehi-
    cle, nor did he ever reference any ‘unknown male’ sup-
    posedly being in the vehicle with them or at the scene
    of the shooting.’’
    Thus, because the petitioner cannot establish a con-
    nection between the murder and the bloodstains, the
    evidence of the CODIS match does not satisfy Brady’s
    materiality test. See State v. Rosa, supra, 
    196 Conn. App. 504
    ;11 see also Carmon v. Commissioner of Cor-
    rection, 
    114 Conn. App. 484
    , 492, 
    969 A.2d 854
     (Counsel
    was not deficient for failing to investigate cartridge box
    that ‘‘was not found at the crime scene, and there was
    no evidence as to when or how it was deposited in
    the area . . . . The box was empty, the caliber of the
    ammunition that had been contained in that box was
    unknown, there was no eyewitness testimony that the
    shooter had been seen taking cartridges from a box,
    and there was no testimony or evidence linking that
    box to the crime scene.’’ (Footnote omitted.)), cert.

    Accordingly, we conclude that the habeas court prop-
    erly determined that the petitioner failed to establish
    materiality and, therefore, did not abuse its discretion
    by denying the petition for certification to appeal as to
    this claim.
    B
    Finally, the petitioner claims that the state committed
    a Brady violation by failing to disclose, as impeachment
    evidence, certain testimony Browning gave in a sepa-
    rate, prior criminal trial, State v. Holbrook, Superior
    Court, judicial district of Fairfield, Docket No. CR-00-
    0163353-T (Holbrook case). We agree with the respon-
    dent that this claim is unreviewable because the habeas
    court correctly concluded that it was abandoned.
    In his petition for a writ of habeas corpus, the peti-
    tioner alleged that his ‘‘due process rights in [the under-
    lying criminal case] were violated because the state had
    information that [Browning], the only witness who put
    the petitioner at the scene of the crime, had previously
    testified in [the Holbrook case]. . . . At that time
    [Browning] admitted that he had lied under oath . . .
    and said he would lie to protect himself. This informa-
    tion was not disclosed to trial or appellate counsel.’’
    At the habeas trial, the petitioner sought to admit the
    transcript of Browning’s testimony in the Holbrook case
    as a full exhibit, but the court sustained the respon-
    dent’s objection.12 Following the trial, the petitioner
    did not address the claim in his posttrial brief and,
    therefore, presented no argument as to why the state’s
    failure to provide the testimony violated his due process
    rights. In its memorandum of decision, the court
    deemed the claim abandoned, stating that ‘‘[t]he peti-
    tioner failed to address this issue at all in his posttrial
    brief’’ and citing Walker v. Commissioner of Correction,
    
    supra,
     
    176 Conn. App. 856
    , to support its conclusion
    that the claim was abandoned.
    ‘‘It is well settled that [w]e are not required to review
    issues that have been improperly presented to this court
    through an inadequate brief. . . . Analysis, rather than
    mere abstract assertion, is required in order to avoid
    abandoning an issue by failure to brief the issue prop-
    erly. . . . Where a claim is asserted in the statement
    of issues but thereafter receives only cursory attention
    in the brief without substantive discussion or citation
    of authorities, it is deemed to be abandoned. . . .
    These same principles apply to claims raised in the trial
    court. . . .
    ‘‘[T]he idea of abandonment involves both a factual
    finding by the trial court and a legal determination that
    an issue is no longer before the court, [therefore] we
    will treat this claim as one of both law and fact. Accord-
    ingly, we will accord it plenary review.’’ (Citation omit-
    ted; emphasis omitted; internal quotation marks omit-
    ted.) 
    Id.
    As noted, in the present case the petitioner did not
    address this claim in his posttrial brief and provided
    no support for or reference to the claim in his habeas
    petition. Furthermore, the petitioner has not contested
    or addressed the court’s conclusion that the claim was
    abandoned and has provided us with no reasons as to
    why the habeas court erred in so finding. On these facts,
    we conclude that the habeas court properly deemed
    the claim abandoned.
    The appeal is dismissed.
    In this opinion the other judges concurred.
    1
    Practice Book § 23-36 provides that ‘‘[a] party may, consistent with the
    rules of evidence, offer as an exhibit, or the habeas court may take judicial
    notice of, the transcript and any portion of the Superior Court, Appellate
    Court or Supreme Court record or clerk’s file from the petitioner’s criminal
    matter which is the subject of the habeas proceeding.’’
    2
    In so ruling, the court stated: ‘‘I mean, here’s the thing, counsel—and I
    get that there’s a Practice Book section. And I’ll put the record out this
    way. You can submit—and I know the Practice Book section allows the
    expanded record to be submitted. Here’s my view and I’ve written on this.
    It is not my job as the judge to search through the evidence to find things
    that support any lawyer’s claims. So, to the exten[t] you are admitting the
    underlying record, you will still need to point the court to the parts of that
    record that are relevant and you believe support the claims that you make
    because otherwise I then step into the role of advocate or taking position
    for one side or the other as opposed to somebody saying to me, ‘This
    particular piece of evidence, Your Honor, supports my claim of X.’ So I
    don’t know that I can stop you from saying I want the court as a matter of
    record to consider the underlying trial record. But, to the extent you believe
    any of that is relevant, you’re going to want to address it. . . . [A]nything
    can be part of the record. What I’m telling is this is as I said it’s not the
    court’s job to sift through the record to find things. So to the extent that
    you’re entering the exhibits from the underlying trial, that’s great. Your job
    is going to be this particular piece of evidence, Judge, is relevant to my
    claim because X, not my job to look through the record and go, ‘Oh, this
    is kind of neat; I think this is relevant,’ or ‘I think I should give them points
    for this.’ That’s all I’m saying. So, the record is what it is, and the record’s
    always going to be what it is. It’s counsel’s job to marshal that evidence
    and to tell me how they are claiming it should be used. And just saying,
    ‘Here’s the record, Judge; I think the record as a whole supports my position.’
    That’s not the court’s job.’’

    Peter Valentin, a lecturer at the Forensic Science Department of the
    University of New Haven, testified as a forensic science expert on the
    petitioner’s behalf. The habeas court specifically determined that his testi-
    mony ‘‘was neither compelling nor enlightening.’’ See part III B of this opin-
    ion.
    4
    ‘‘CODIS contains DNA profiles from unsolved crimes and compares them
    to known samples from convicted felons that are periodically added to the
    database. See, e.g., State v. Webb, 
    128 Conn. App. 846
    , 852–53 n.3, 
    19 A.3d 678
    , cert. denied, 
    303 Conn. 907
    , 
    32 A.3d 961
     (2011).’’ State v. Rodriguez,
    
    337 Conn. 175
    , 180 n.2, 
    252 A.3d 811
     (2020).
    5
    Valentin specifically testified: ‘‘[I]n the photograph on the right side of
    the image there is a large—there’s a collection of blood adjacent to a baseball
    cap. That is inconsistent toward—it is not in the same position as the
    decedent was found or as he’s photographed here. Additionally, there is a
    smaller blood stain in the vicinity of the decedent’s left arm that also suggests
    some movement after the injury occurred. And then there’s also some—
    there are additional stains in the vicinity of that what I would call a linear
    pattern near his arm that also are suggestive of movement.’’
    6
    Specifically, Valentin testified that he ‘‘would have suggested to [trial]
    counsel that the distance that that bloodstain is from the cluster of activity
    for lack of a better way of describing it where [the victim’s] body was
    located suggests that that stain has relevance because my assessment would
    be that there’s essentially two ways for that bloodstain to get there or there’s
    two sources for that blood. Either that blood is [the victim’s] blood and it
    has been brought to that location twenty some odd feet away from the
    scene because it was on an object or that blood belongs to somebody who
    was bleeding at a time recently because the snow would suggest temporally
    when that would have occurred.’’
    7
    In discussing another claim, the habeas court noted that evidence regard-
    ing the condition of the victim’s body supported the state’s theory at trial
    that the petitioner and Browning robbed the victim after he was killed.
    8
    In addition, this testimony did not take into account the fact that the
    petitioner’s trial counsel was not informed about the DNA match to the
    bloodstain; see part IV A of this opinion; nor did it contemplate the fact it
    was undisputed that the car had been destroyed by the time trial counsel
    started representing the petitioner.
    9
    In making this argument, the petitioner points to information that his
    trial counsel would have discovered, had he conducted a ‘‘proper investiga-
    tion.’’ The habeas court, however, excluded the evidence purporting to
    establish what his trial counsel would have discovered. Although the peti-
    tioner notes in his principal appellate brief that ‘‘[i]nformation regarding
    what happened to the victim’s car after it was impounded by the police was
    improperly excluded,’’ he did not raise a claim of error with respect to this
    ruling on appeal.
    10
    The court also determined that the petitioner failed to prove that his
    trial counsel’s performance was deficient. Because we agree that the peti-
    tioner failed to prove prejudice, we need not consider the court’s determina-
    tion concerning trial counsel’s deficient performance. See Schuler v. Com-
    missioner of Correction, 
    supra,
     
    200 Conn. App. 617
    .
    11
    The petitioner attempts to distinguish Rosa, arguing that the evidence
    in the present case ‘‘was definitely connected to the crime’’ because the car
    belonged to the victim while the sweatshirt in Rosa ‘‘was not connected to
    the crime’’ and that the state’s case was not strong in the present case
    while ‘‘there was strong evidence inculpating the defendant’’ in Rosa. These
    arguments are unavailing.
    First, the fact that the vehicle belonged to the victim is not enough to
    connect it to the crime, as mere ownership and some proximity to the crime
    scene do not in and of themselves implicate the vehicle’s involvement.
    Second, the court in Rosa determined that the sweatshirt was not connected
    to the case because of the collective facts. State v. Rosa, supra, 
    196 Conn. App. 504
    , 509. Similarly, in the present case, the collective facts result in a
    conclusion that the car is not connected to the case. Further, in Rosa, the
    ‘‘strong evidence inculpating the defendant’’ was only one factor of many
    bearing on the determination that the sweatshirt was not material to the
    case. Id., 509.
    12
    The petitioner has not raised on appeal a claim that the court erred in
    excluding from evidence the transcript of Browning’s testimony from the
    Holbrook case.
