    SCHUMACHER, Judge.
    I.     Background Facts.
    Brian Davis was convicted of the murder of his fiancé, Holly Durben, on
    February 16, 2015, over five years after her body was recovered in an upstairs
    bedroom of the home Durben shared with Davis. Davis informed law enforcement
    that Durben had committed suicide. We previously detailed the facts of this case
    in Davis’s direct appeal in which we affirmed Davis’s conviction. See State v.
    Davis, No. 15-0666, 
    2017 WL 108278
    , at *1−3 (Iowa Ct. App. Jan. 11, 2017).
    Facts relevant to the postconviction relief (PCR) proceeding follow.
    II.    Proceedings.
    On November 7, 2014, Davis was charged by trial information with the first-
    degree murder of Durben. Davis demanded a speedy trial and waived his right to
    a jury trial. A bench trial commenced on February 3, 2015. The court returned a
    guilty verdict on February 16. An amended verdict was filed on March 4. Judgment
    was entered on April 9. Davis was sentenced to life imprisonment. Davis appealed
    his conviction, and we affirmed. Davis, 
    2017 WL 108278
    , at *1.
    On August 3, 2017, Davis filed a PCR application, claiming his counsel was
    ineffective in several respects. In preparation for the PCR trial, Davis conducted
    depositions of his three criminal defense lawyers1; retained and deposed crime
    scene processing expert Kenneth Moses; deposed Corey Wasenius, an
    1One  of Davis’s defense counsel assisted in the case pro bono and has experience
    working as both a prosecutor and a defense attorney. Another defense counsel
    worked as a public defender for ten years and has been involved in approximately
    twenty-five class “A” felony trials, both as a prosecutor and defense attorney. The
    third defense counsel has been a public defender since 2010 and specializes in
    class “A” felonies.

    investigator with the Iowa Public Defender’s Office; and submitted a letter from a
    mental-health therapist, Cynthia Freemyer, describing the risk for lethality in a
    client expressing suicidal ideation. Additional evidence not in the record at the
    criminal trial was introduced in the PCR proceedings, including the medical
    examiner’s autopsy report, transcripts of the pre-trial depositions of witnesses
    Jamie Stockwell and Michael Halverson, and a 2009 call log from the medical
    examiner’s office.
    On October 5, 2018, the district court held an evidentiary hearing. At the
    conclusion of the PCR hearing, the district court requested proposed orders from
    the parties. The district court adopted the State’s order in its ruling.2 The district
    court denied Davis’s PCR application. On October 17, Davis’s counsel filed a
    motion to enlarge and reconsider. On October 23, Davis filed a pro se motion to
    enlarge and reconsider. On November 26, the motions were overruled, and on
    November 27, Davis filed a notice of appeal. Davis is represented by counsel on
    this appeal and also submitted a pro se brief.3
    2 We note Davis’s objection to the district court’s adoption of the State’s proposed
    order. Davis asks this court to apply a less deferential standard of review in his
    case. We have previously declined to adopt an alternative standard of review in
    similar circumstances. See Richter v. State, No. 15-1800, 
    2017 WL 935064
    , (Iowa
    Ct. App. March 8, 2017). However, we recognize the necessity to review the
    record conscious of the fact that the State prepared the order and will “scrutinize
    the record more carefully when conducting our appellate review.”                  See
    NevadaCare, Inc. v. Dep’t of Human Servs., 
    783 N.W.2d 459
    , 465 (Iowa 2010). At
    oral argument, the State invited careful scrutiny of the record.
    3 The State argues that we should disregard Davis’s pro se filings.            Recent
    legislation, S.F. 589, effective July 1, 2019, prohibits applicants from filing pro se
    briefs if they are already represented by counsel. 
    Iowa Code § 822
    .3B(1) (2019)
    (“An applicant seeking relief under section 822.2 who is currently represented by
    counsel shall not file any pro se document, including a brief, reply brief, or motion,
    in any Iowa court. The court shall not consider, and opposing counsel shall not
    respond to, such pro se filings.”). Davis filed his notice of appeal on November 27,
    4
    III.   Discussion—Arguments Prepared by Counsel.
    Through counsel’s brief,4 Davis points to several instances where he
    believes counsel’s performance was deficient. At oral argument, Davis argued the
    heart of his PCR appeal are issues of credibility and complacency—specifically the
    failure of counsel to attack the credibility of witnesses, urging that because the
    physical evidence is inconclusive credibility is key.         Davis further argues
    complacency on behalf of his counsel rose to the level of recklessness. Davis’s
    arguments center around four broad issues: (1) the medical examiner’s testimony
    and her reliance on certain information; (2) the testimony of witness Stockwell and
    her impeachment; (3) the use of particular statements made by Davis and trial
    counsel’s exclusion efforts as well as appellate counsel’s advocacy on this issue;
    and (4) crime scene processing and lack of expert witnesses.
    2018. In State v. Macke, the Iowa Supreme Court held amendments to S.F. 589
    dealing with guilty pleas and ineffective assistance of counsel did not apply
    retroactively to appeals pending on July 1, 2019. 
    933 N.W.2d 226
    , 228 (Iowa
    2019). Macke upheld long-standing precedent that “unless the legislature clearly
    indicates otherwise, statutes controlling appeals are those that were in effect at the
    time the judgment or order appealed from was rendered.” Id. at 231 (quotations
    omitted). The State argues Macke is not controlling because the amendments at
    issue in Macke affect a defendant’s right to appeal or limit the types of claims he
    may bring, whereas section 822.3B “only changes the procedure for how he may
    present his claims . . . .” This court recently rejected the same argument with
    respect to pro se filings of a defendant on direct appeal. See State v. Krone,
    No. 18-0130, 
    2020 WL 821935
    , at *3-4 (Iowa Ct. App. Feb. 19, 2020). Similarly,
    we find no suggestion in Macke that the supreme court would treat amendments
    in S.F. 589 not at issue in Macke differently. We conclude we may consider Davis’s
    pro se filings.
    4 There is significant overlap between the briefs submitted by counsel and Davis’s
    pro se brief. We first address the issues raised by counsel and follow with the
    issues remaining in Davis’s pro se brief. Where the issues raised in both briefs
    are sufficiently related, we address them as part of the arguments prepared by
    counsel.
    5
    A.     Standard of Review
    A PCR applicant may raise the issue of ineffective assistance of counsel
    without preserving the issue on direct appeal.      
    Iowa Code § 814.7
    (1) (2017).
    Appellate review of PCR proceedings is typically for correction of errors at law.
    Ledezma v. State, 
    626 N.W.2d 134
    , 141 (Iowa 2001). However, applications that
    allege ineffective assistance of counsel implicate an applicant’s constitutional
    rights and therefore require de novo review. Id.; State v. Lorenzo Baltazar, 
    935 N.W.2d 862
    , 868 (Iowa 2019). To establish an ineffective-assistance-of-counsel
    claim requires the applicant to show by a preponderance of the evidence that: “(1)
    trial counsel failed to perform an essential duty, and (2) [the] failure resulted in
    prejudice.” Sauser v. State, 
    929 N.W.2d 816
    , 818 (Iowa 2019) (citation omitted);
    accord Strickland v. Washington, 
    466 U.S. 668
    , 687 (1984). Failure to prove either
    prong is fatal to an ineffective-assistance-of-counsel claim. State v. Tompkins, 
    859 N.W.2d 631
    , 637 (Iowa 2015).
    Under the first prong, “we begin with the presumption that the attorney
    performed competently.” Ledezma, 
    626 N.W.2d at 142
    . We “must indulge a
    strong presumption that counsel’s conduct falls within the wide range of
    reasonable professional assistance.” State v. Haas, 
    930 N.W.2d 699
    , 703 (Iowa
    2019) (citation omitted). An applicant must rebut the presumption by proving trial
    counsel “perform[ed] below the standard demanded of a reasonably competent
    attorney.” 
    Id.
     (citation omitted). “This is more than a showing that a trial strategy
    backfired or that another attorney would try the case differently.” Lorenzo Baltazar,
    935 N.W.2d at 869. “We will not find counsel incompetent for failing to pursue a
    meritless issue.” State v. Brubaker, 
    805 N.W.2d 165
    , 171 (Iowa 2011). Under the
    6
    second prong, to establish prejudice, “a[n] [applicant] must show a reasonable
    probability that the result of the trial would have been different.” State v. Ambrose,
    
    861 N.W.2d 550
    , 557 (Iowa 2015). “A reasonable probability is a probability
    sufficient to undermine confidence in the outcome.” Strickland, 
    466 U.S. at 694
    .
    B.     Medical Examiner’s Testimony
    On direct appeal, Davis claimed his trial counsel was ineffective in their
    performance regarding the testimony of Associate State Medical Examiner,
    Dr. Jerri McLemore. We found the record insufficient on Davis’s direct appeal to
    resolve the claim and left the issue open for PCR proceedings.5 Davis, 
    2017 WL 108278
    , at *11. On appeal from denial of his PCR application, Davis takes issue
    with counsel’s performance related to Dr. McLemore in three respects: (1) Dr.
    McLemore’s reliance on certain contested information, (2) portions of her
    testimony, and (3) the decision not to hire an expert witness.
    1.     Medical Examiner’s Reliance on Contested Information
    First, Davis argues that Dr. McLemore improperly relied on two pieces of
    information: (a) evidence existed showing that Davis had “high-velocity blood
    splatter” on his clothing and (b) Durben had no history of suicidal ideation. Davis
    contends that his trial counsel was ineffective for not correcting this information
    prior to trial, not competently cross-examining Dr. McLemore, and not informing
    the fact-finder of the contested information.
    5Our 2017 decision on Davis’s direct appeal noted that Dr. McLemore’s deposition
    was not part of the record. Dr. McLemore’s deposition from the criminal trial was
    also not included in the PCR record.
    7
    a.     2009 Autopsy Report
    In July 2009, Dr. McLemore conducted an autopsy of Durben and filed a
    report of her findings on December 17. The report found both the cause and
    manner of death to be undetermined. In the opinion section of the autopsy report
    outlining the basis for her conclusion, Dr. McLemore stated, “There were, however,
    subtle discrepancies regarding a possible high-velocity blood spatter on the
    significant other’s clothing.” Additionally, the report states, “Further investigation
    revealed that the decedent had no history of suicidal ideation or suicidal attempts.”
    The report concludes, “Aspects of the scene investigation, autopsy findings, and
    decedent’s history, namely, lack of any suicidal ideation raise the possibility of
    homicide. Incapacitation of the decedent from choking cannot be excluded. Based
    on the circumstance as they are currently known, the manner of death is
    undetermined.”
    b.     2015 Trial Testimony
    At trial in 2015, Dr. McLemore’s 2009 autopsy report was not submitted into
    evidence. Dr. McLemore testified that the basis of her undetermined conclusion
    was:
    Because of the location of the shotgun wound, which is highly
    unusual for a self-inflicted shotgun wound, because of the partial
    bruising of the neck, which I had no good answer as to why they were
    there, I could not say one way or the other whether Ms. Durben
    actually did die of a shotgun wound to the head.
    I could not say whether or not she might have been
    incapacitated beforehand. And so because of that, I could not
    determine the cause or manner of death. They were both deemed
    undetermined.
    8
    c.     Contested Information—“High-Velocity Blood Spatter”
    On the morning of Durben’s death, Davis’s clothing was seized prior to the
    issuance of a search warrant while Davis was in the hospital.6 Davis’s shirt and
    shorts were sent to the Iowa Division of Criminal Investigation (DCI) Crime Lab for
    analysis.     Criminalist Michael Halverson was responsible for testing Davis’s
    clothing. On January 8, 2015, in preparation for Davis’s criminal trial, Halverson
    was deposed by Davis’s defense counsel.7 Halverson was asked whether he
    conducted high-velocity blood splatter testing on Davis’s clothing.      Halverson
    explained that no testing was done because the splatter on the shorts was too
    small to conduct high-velocity blood spatter testing.
    Despite the inability to conduct high-velocity blood spatter testing,
    Dr. McLemore’s autopsy report referenced “possible high-velocity blood spatter on
    the significant other’s clothing.” Dr. McLemore testified that when making a report,
    she considers the circumstances of death. In Durben’s case, she received a
    preliminary report from the county medical examiner and the DCI file related to the
    case. It appears that sometime during the initial stages of the investigation, the
    possibility of high-velocity blood splatter testing was considered by investigators.
    This information was given to Dr. McLemore, and she included it in her autopsy
    report.
    6 On the morning of the trial in 2015, the clothing was suppressed, as the seizure
    was found to be in violation of the Fourth Amendment by the trial court.
    7 The deposition revealed that Halverson examined Davis’s shorts and identified
    twelve small stains, ten of which were identified as blood. DNA testing was
    conducted on the stains, nine matched Davis, and one returned a mixed result with
    the dominant source matching Durben.
    9
    Davis argues his trial counsel was required to correct the autopsy report
    prior to trial. However, the report was not admitted into evidence at the criminal
    trial, and Dr. McLemore did not testify regarding the contested information. She
    made no mention of “possible high-velocity blood spatter on the significant other’s
    clothing” during the course of her testimony. Removing the information prior to
    trial would have little, if any, effect on the evidence actually presented at trial. We
    find a lack of prejudice concerning this claim.
    d.     Contested Information—“Suicidal Ideation”
    The 2009 autopsy report indicates Durben lacked suicidal ideation.
    Dr. McLemore testified that lack of suicidal ideation formed a basis for her
    conclusion.   Conflicting testimony and evidence of Durben’s suicidal ideation
    leading up to the morning of her death was presented at trial. Dr. McLemore was
    told by investigators that Durben lacked suicidal ideation.8 Davis asserts his
    defense counsel’s treatment of Dr. McLemore’s reliance on this information was
    constitutionally deficient. We disagree.
    In his deposition, one of the defense counsel was questioned about defense
    strategy with regard to the medical examiner’s reliance on the contested
    information. He explained it was something he sought to point out for the court
    “from the get-go” and that their strategy was to show “[Dr. McLemore] was skewed
    and that she had been given this information prior to doing the autopsy.” In the
    8 As a part of his application for postconviction relief, Davis submitted into the
    record for the first time a 2009 call log from the medical examiner’s office. The log
    indicates that on October 27, 2009, a member of the Area Prosecutions Division
    of the Attorney General’s Office called the medical examiner, and Dr. McLemore
    noted, “Holly—No known history of suicidal ideation—very against suicide.”
    10
    opening statement, defense counsel made clear the potential weaknesses in Dr.
    McLemore’s autopsy report. He argued,
    But if you listen to Dr. McLemore’s testimony . . . listen to what
    forensic—what her forensic autopsy takes into account. This is not
    just a review of the body. This is her taking into account the
    circumstances that are told to her by law enforcement. . . .
    ....
    . . . She was told by law enforcement on further investigation
    that there was not—no suicidal ideations regarding Holly. . . . [Y]ou
    are going to hear three separate witnesses talk about the fact that
    Holly Durben had threatened suicide.
    On cross-examination, a member of the defense team elicited testimony
    from Dr. McLemore that established she had received information that Durben
    lacked suicidal ideation. He specifically pointed out the portion of the autopsy
    report that states a lack of suicidal ideation raised the possibility of homicide.
    Counsel went on to question Dr. McLemore about how this information influenced
    her conclusion:
    Q. If there was suicidal ideation either that day or over a period
    of time of up to [five] months before, would that have affected your
    opinion? A. Probably not.
    ....
    Q. Again, I’m reading your report, and it says the thing that
    bothered you was mainly lack of any suicidal ideation raised the
    possibility of homicide. So removing that possibility— A. Yes.
    Q .—doesn’t that affect you at least somewhat? A. Because
    I still have aspects of, especially my autopsy findings in that
    sentence. It’s not just one piece of evidence that is concerning me—
    Q. Okay. A.—or has concerned me. Anyway, I couldn’t form
    an opinion. That’s why it’s undetermined.
    Counsel’s questioning adequately confronted Dr. McLemore about her
    reliance on a lack of suicidal ideation.       Trial counsel’s subsequent line of
    questioning tested the report’s conclusion under an alternative where there was
    suicidal ideation. The questioning by counsel of Dr. McLemore concerning her
    11
    conclusion raised the issue and alerted the trial court to the issue. We find no
    breach of duty.
    2.     “Highly Unusual Wound”
    On direct appeal, Davis specifically argued that his counsel was ineffective
    for not lodging a foundational objection to Dr. McLemore’s statement that the
    shotgun wound was in a “highly unusual place.” Davis, 
    2017 WL 108278
    , at *11.
    We stated that it was unclear whether Dr. McLemore “could have provided the
    requisite foundation for her statement.” 
    Id.
     Additionally, we noted the possibility
    of prejudice because the State identified Dr. McLemore’s testimony as “the
    strongest evidence of Davis’s guilt,” and “the district court relied upon her expert
    testimony in its verdict.” 
    Id.
     at *11 n.12. Finally, we acknowledged the State’s
    argument that “defense counsel may have had reasonable strategic grounds for
    failing to object to Dr. McLemore’s testimony.” Id. at *11. On this appeal, Davis
    contends his counsel was ineffective in cross-examining the witness on her “highly
    unusual” location claim and failing to seek a continuance in order to hire an expert
    witness to contest it. We reject this argument.
    First, defense counsel made a reasonable and strategic objection to the
    contested testimony. When confronted with the unexpected testimony, defense
    counsel objected, arguing the testimony was “beyond the scope of the trial
    information and beyond the scope of the deposition.” Counsel engaged in voir dire
    of the witness where counsel established that Dr. McLemore’s opinions were given
    to a reasonable degree of medical certainty and that when asked in her deposition,
    she was able to give no opinion as to the cause and manner of death. Defense
    counsel argued that any opinions offered beyond that would not be to a reasonable
    12
    degree of medical certainty. The trial judge overruled the objection. The trial
    court’s ruling on the objection was challenged on direct appeal, and we affirmed.
    Id. at *7.
    Defense counsel, as well as the State at trial, acknowledged that a
    foundational objection also could have been made. However, in his deposition,
    defense counsel explained his strategy in avoiding a foundation objection and in
    not pursuing a line of questioning related to the witness’s expertise and knowledge.
    In the view of counsel, Dr. McLemore’s testimony left clear reasonable doubt and
    the testimony as favorable to the defense. Defense counsel did not want to
    “bolster” the witness for the State. He explained, “True expert witnesses will
    bolster their testimony whether they have any real basis to bolster it or not. . . . It’s
    not our job to bolster that. And so I felt any foundational questions about that would
    only assist the State . . . .” Defense counsel also noted the potential risk of lodging
    a foundational objection, “Well, you take a risk on that. Any time you’re going to
    ask—if I ask to voir dire a witness, I’m going to say what’s your experience in this
    area, and she then throws out that she’s got [eighty-two] papers in it, I have helped
    the State.” A member of the defense counsel team testified in his deposition taken
    in advance of the PCR trial that he did not anticipate that Dr. McLemore would be
    testifying that the location of the wound was “highly unusual.”            Thus, when
    presented with the unanticipated testimony, counsel made a strategic decision to
    object to the offered testimony being outside the scope of the trial information and
    her prior deposition. This effectively brought the issue to the attention of the court
    and presented the issue. Trial counsel’s actions and strategy were reasonable
    given the circumstances. We find no breach of duty in this regard.
    13
    Second, Davis asserts that his defense counsel was required to seek a
    continuance when confronted with Dr. McLemore’s testimony. Davis points to the
    fact that in his deposition, defense counsel was asked what he would have done
    differently had he known prior to trial that Dr. McLemore would testify as she did.
    Defense counsel responded that, “[W]e also mostly would have gone and hired
    our own expert to then refute that statement because we don’t believe that doctor’s
    statement would have been based on recent research.” Additionally, Davis points
    to another of defense counsel’s statements that “in hindsight,” trial counsel may
    have been ineffective for not seeking a continuance to hire an expert to contest Dr.
    McLemore’s testimony.
    However, defense counsel’s statements that Davis now points to are
    responses to a hypothetical question.       What strategy might have been more
    successful upon reflection does not establish that trial counsel was ineffective.
    Counsel’s performance is judged under the circumstances known to them at the
    time. “[T]o some extent counsel’s trial performance must be judged by his primary
    theory of defense. Selection of the primary theory or theories of defense is a
    tactical matter.” Schrier v. State, 
    347 N.W.2d 657
    , 663 (Iowa 1984).
    Defense counsel believed the case against Davis was weak and
    strategically chose to give the State as little time to prepare for trial as possible,
    demanding speedy trial. Defense counsel stated in his deposition,
    [W]e felt that we were going to try to hold the State to their burden
    sooner than later because we didn’t think that they could be prepared
    as well as they could if they were given more time.
    And I think a lot of that was shown in the scrambling that the
    State had at the last minute.
    14
    It was reasonable and consistent with trial strategy not to seek a continuance,
    thereby forcing the State to prove their case under the expedited timeframe. When
    confronted with Dr. McLemore’s testimony, counsel fulfilled their duty by making a
    reasonable objection, strategically choosing not to pursue a foundation objection
    so as to not potentially bolster the witness or alternatively undermine a witness
    whose overall conclusion they found in line with a finding of not guilty. Given the
    circumstances and what was known to counsel at the time, this was a reasonable
    strategy within the range of competent representation.
    Critically, Davis has not offered how the hiring of an expert would have
    changed the outcome. An expert was not presented at the PCR trial to counter
    Dr. McLemore’s testimony concerning the location of the gunshot wound. The trial
    court was presented with evidence by way of Davis’s statements that he was not
    in the room when Durben was shot. During one of his interviews, he informed law
    enforcement that when he discovered Durben’s body, he jumped on the bed,
    moved the gun out of the way, and shook Durben. In another interview, he said
    he moved the gun slightly and shook her before calling law enforcement. When
    law enforcement discovered Durben, the gun was lying across her body, the finger
    from her non-dominant thumb in the trigger jam, supporting the State’s theory that
    the suicide scene was staged. Davis told investigators that he had unloaded the
    gun early that morning and placed it under the bed on which Durben’s body was
    discovered. The only identifiable fingerprint located on the weapon belonged to
    Davis. Davis has failed to prove that the hiring of an expert concerning the location
    of the gunshot wound would have changed the outcome of the trial. We find a lack
    of prejudice concerning this claim.
    15
    3.     Necessity of Obtaining Additional Forensic Expert
    Finally, Davis argues his counsel was required to hire an expert to review
    the medical information provided to Dr. McLemore without the contested
    information. We disagree. In his deposition, defense counsel noted, “We looked
    at hiring a blood-splatter person. We looked at talking about the psycholog[ical]
    aspects of suicide. We looked at the experts as to whether women commit suicide
    by shotgun.” However, he went on to explain that once the decision to demand a
    speedy trial was made other strategies concerning expert witnesses changed.
    Defense counsel did not have a duty to hire an expert witness when
    Dr. McLemore’s conclusion was not necessarily adverse to their position and doing
    so would conflict with their trial strategy. See Schrier, 
    347 N.W.2d at 663
     (finding
    counsel did not breach an essential duty for not hiring an expert witness to counter
    State’s medical expert witness where there “were more appealing theories of
    defense than a possible battle of expert witnesses”). Counsel considered these
    issues and made a strategic decision not to delay trial. “[S]trategic choices made
    after a thorough investigation of law and facts relevant to plausible options are
    virtually unchallengeable; and strategic choices made after less than complete
    investigation are reasonable precisely to the extent that reasonable professional
    judgments support the limitations on investigation.” Strickland, 
    466 U.S. at
    690–
    91.
    Additionally, Davis has not proven to a reasonable probability that such an
    expert existed and would have offered a favorable opinion. See Stewart v. Nix, 
    31 F.3d 741
    , 744 (8th Cir. 1994) (“To prove prejudice from a trial attorney’s failure to
    investigate potential witnesses, a petitioner must show that the uncalled witnesses
    16
    would have testified at trial and that their testimony would have probably changed
    the outcome of the trial.”). In supporting this claim, Davis points to the fact that
    defense counsel was aware of research that conflicted with Dr. McLemore’s
    testimony and submitted a letter from mental-health therapist Cynthia Freemyer.
    However, Freemyer’s letter states nothing specific to Durben and is merely a
    description of the standard treatment for a client expressing suicidal ideation.
    Davis has not presented a witness who could have testified to conflicting research
    or shown that it would have changed the result of his trial. We find Davis has failed
    to prove prejudice on this claim.
    4.     Conclusion—Medical Examiner
    In conclusion, we find that Davis has not proven his defense counsel’s
    performance was constitutionally ineffective in regards to medical examiner
    Dr. McLemore.      No prejudice at trial resulted from the 2009 autopsy report’s
    reference to the possibility of high-velocity blood splatter. Counsel fulfilled their
    duty by effectively cross-examining Dr. McLemore about Durben’s suicidal
    ideation, and the contested information was made clear to the court.           When
    confronted with testimony describing the location of the shotgun wound as “highly
    unusual,” defense counsel acted competently by making a reasonable objection
    and were not required to seek a continuance in counter-variance of their trial
    strategy. Even if a breach were to be found for failing to move for a continuance,
    Davis has failed to prove prejudice on this claim. Finally, counsel did not have an
    essential duty to hire an expert witness to review partially redacted medical reports,
    and Davis has not shown doing so would have resulted in a result favorable to him
    at trial.
    17
    C.     Witness Stockwell
    Davis claims his counsel’s performance with regard to witness Jamie
    Stockwell was ineffective. In the early hours of the morning of her death, Durben
    texted Stockwell asking if she could stay with her. After receiving the message,
    Stockwell called Durben, but she did not pick up. Around 4:00 a.m., Stockwell left
    voicemail messages on both Stockwell’s cell phone and Davis’s home phone line
    inquiring whether Durben was safe. Stockwell kept calling and eventually spoke
    with Durben and Davis. Stockwell testified at trial concerning her relationship with
    Durben and her conversation with Durben on the morning of her death. Davis
    asserts his trial counsel was deficient: (1) in failing to object to her reference to a
    text message9 and (2) in challenging her credibility on cross-examination.
    1.     Text Message
    In his pro se brief, Davis claims his counsel was ineffective for failing to
    object on hearsay grounds to a portion of Stockwell’s testimony that referenced
    the text message she received from Durben on the morning of her death. The
    States argues the statements were admissible under the excited-utterance and
    then-existing state-of-mind hearsay exceptions. See Iowa Rs. Evid. 5.803(3)(2),
    (3).   Defense counsel made a hearsay objection in response to Stockwell’s
    testimony concerning her telephone conversation with Davis and Durben. The
    State responded by arguing the statements qualify for the then-existing state-of-
    9This basis was asserted in Davis’s pro se brief and not included in counsel’s brief.
    Because both claims of ineffective assistance of counsel involve the same witness,
    we consider them together here. Davis raised the issue in his application. The
    district court considered the claim and denied his application. The claimed error is
    preserved.
    18
    mind hearsay exception. The objection was overruled. Assuming trial counsel
    was able to exclude evidence of the text message successfully, Davis has not met
    the prejudice prong. The evidence of consequence was Stockwell’s conversation
    with Durben on the morning of her death not the text message. We find no
    prejudice in this regard.
    2.     Counsel’s Challenge to Stockwell’s Credibility
    Stockwell made statements relevant to this case on three separate
    occasions. They are presented in chronological order and then discussed as a
    part of Davis’s claim.
    a.     2014 Interview with Investigators
    On October 31, 2014, Stockwell was interviewed by Special Agent Chad
    Fiedler. As the interview was concluding, Agent Fiedler asked, “Are you scared of
    Brian?” Stockwell responded,
    Am I scared of him? I’m not scared of nobody. [laugh] I’ve, I’ve just
    reached that point. I don’t care what you are—male or female. I’m
    not scared of nobody, and I’m not gonna back down. But I’m not
    gonna say I’m gonna win or anything, but I’ll try. [laugh] [pause]
    Nope, I’m not scared of him, actually I had actually told him a few
    times if he got stupid I was gonna get stupid on him.
    Davis’s defense counsel had an audio recording of the interview as well as a report
    generated by investigators describing the interview prior to trial.
    b.     2015 Deposition
    On Jan 27, 2015, one week before trial, Stockwell was deposed. Davis was
    present during the deposition. In her deposition, Stockwell stated that Durben had
    spoken to her about committing suicide “multiple times.” Stockwell stated that
    while on the phone with Durben on the morning of her death, Durben told her “that
    19
    if she didn’t get out of there or didn’t have anywhere to go, then she was going to
    end up committing suicide,” and “that she wanted help; she wanted to get out of
    there, and she wanted me to come help her.”
    c.     Trial Testimony
    At trial, Stockwell testified about the morning of Durben’s death. She was
    cross-examined by defense counsel, and the following line of questioning
    occurred:
    Q. Holly made suicidal statements to you when Brian and her
    were having arguments, didn’t she? A. She told me she wanted out
    of there and wanted me to help her get away. She was done. She
    couldn’t handle the hurt and pain and suffering anymore.
    Q. And if she couldn’t get away, she was going to kill herself?
    A. She told me that five months prior to this happening.
    Defense counsel confronted Stockwell about the statements she made in her
    earlier deposition. Defense counsel clarified that Stockwell had previously stated
    Durben made suicidal statements multiple times, including the night of her death.
    Stockwell continued to respond by saying that “it had been five months before that
    she had made the last final suicidal statement.” Defense counsel sought to confirm
    that Stockwell had made inconsistent statements a few days earlier in her
    deposition, and the following line of questioning occurred:
    Stockwell: Yep. I said this. I was scared. But it wasn’t—
    Q. What were you scared of, ma’am? A. I didn’t—I have two
    children. And I’m not going to live my life at risk because—I am doing
    what I am doing, which is right.
    Q. Ma’am, did you also say those very same statements to
    investigators in 2014? A. I said quite a bit of statements to
    investigators.
    Defense counsel offered a transcript of Stockwell’s deposition and read into the
    record portions of her deposition that were inconsistent with her testimony. On
    20
    redirect by the State, Stockwell was asked, “Why were you scared at your
    deposition?” Stockwell responded, “I’m still scared. I have every reason. I have
    two children, and I know what Davis is capable of.”
    Stockwell’s deposition testimony that Durben made suicidal statements to
    Stockwell on the morning of her death was helpful for Davis’s defense. Therefore,
    it was imperative for counsel to impeach Stockwell when her trial testimony differed
    so significantly from what she said in her deposition. Counsel fulfilled this duty by
    impeaching Stockwell with her inconsistent statement and reading portions of her
    deposition into the record.    Davis acknowledges that counsel impeached the
    witness with her prior inconsistent statements concerning Durben’s statements
    about suicide.    However, Davis argues counsel was required to also use
    Stockwell’s statements to investigators that she was not afraid of Davis to further
    impeach her. We disagree.
    There are clear strategic advantages in using Stockwell’s depositional
    statements rather than her statements made to investigators for impeachment
    purposes. “We generally entrust cross-examination techniques, like other matters
    of trial strategy, to the professional discretion of counsel.”     United States v.
    Villalpando, 
    259 F.3d 934
    , 939 (8th Cir. 2001). The statements most relevant to
    Davis’s defense were that Durben made suicidal statements on the morning of her
    death. Statements made in a deposition are under oath, allowing them to be
    considered as substantive evidence when brought in through impeachment. By
    using the sworn statements to impeach the witness, defense counsel enabled the
    judge to consider her favorable depositional testimony concerning Durben’s
    suicidal statements as substantive evidence despite her in-court testimony. Use
    21
    of Stockwell’s statements to investigators not under oath could have only been
    offered as extrinsic evidence to prove she made the inconsistent statement rather
    than to prove she was not afraid of Davis. See Iowa R. Evid. 5.613.
    Stockwell’s credibility had been attacked on cross-examination; additional
    impeachment with her statements to investigators would be derivative and would
    do little to undermine her in-court assertion she was scared during her deposition,
    which occurred after she made the statements to investigators. Further, this line
    of questioning risked opening the door to more testimony concerning Stockwell’s
    fear of Davis. Specifically, this line of questioning may have opened the door to
    previously excluded prior bad acts that were within the knowledge of Stockwell—
    that Davis had previously shot a man and stabbed another and that he was abusive
    to a previous girlfriend and had threatened to kill her.
    3.     Conclusion—Witness Stockwell
    We do not find Davis’s counsel was ineffective in the treatment of witness
    Stockwell.   Davis is unable to show prejudice regarding the lack of hearsay
    objection concerning the text given the cumulative evidence of Stockwell’s
    testimony concerning her conversation with Durben the morning of her death.
    Counsel competently and strategically impeached Stockwell with her sworn prior
    inconsistent statements. Counsel did not have an essential duty to pursue further
    impeachment on statements less relevant to Davis’s defense and which posed the
    risk of introducing adverse testimony.
    D.     Court’s Reliance on Davis’s Statements
    1.     Ineffective Appellate Counsel
    22
    Davis claims his appellate counsel was ineffective for failing to raise on
    appeal the trial court’s reliance on allegedly suppressed statements. “We judge
    ineffective assistance of appellate counsel claims against the same two-pronged
    test utilized for ineffective assistance of trial counsel claims.” Ledezma, 
    626 N.W.2d at 141
     (citations omitted).
    At his PCR trial, Davis argued, “There can be no reasonable strategy for
    failing to raise a winning issue on appeal.” However, no other evidence concerning
    appellate counsel’s strategy or decision was presented. An assertion that if the
    issue been raised on appeal, it would have been successful is not sufficient to
    establish ineffective assistance of appellate counsel. See Cuevas v. State, 
    415 N.W.2d 630
    , 631 (Iowa 1987) (reversing this court’s finding of ineffective appellate
    counsel where on direct appeal from defendant’s murder conviction appellate
    counsel failed to raise issue of jury instructions permitting consideration of lesser
    included offenses and argument of the issue in companion appeal led to reversal
    of accomplice’s conviction).
    Further, it is not clear that had Davis raised the issue on direct appeal it
    would have been successful. Many issues were raised in Davis’s motion for a new
    trial and in arrest of judgment. Appellate counsel was required to choose the most
    prudent among them to argue on appeal. “[M]ost experienced appellate lawyers
    or judges will attest it is a tactical blunder, often devastating to an appellant, to
    assign every conceivable complaint.           Highly competent appellate lawyers
    generally assign only the strongest points and rely on them for reversal.” 
    Id. at 633
    . In PCR proceedings, counsel is presumed competent, and it is Davis’s
    burden to prove counsel’s performance fell below what is constitutionally
    23
    mandated. See Jones v. State, 
    479 N.W.2d 265
    , 272 (Iowa 1991). Davis has not
    met his burden to prove that appellate counsel was ineffective.
    2.     Counsel’s Lack of Challenge to Un-Redacted Interview
    Additionally, Davis claims his trial counsel was ineffective for failing to
    redact certain portions of offered evidence related to an interview between Davis
    and investigators. On October 27, 2014, Davis was interviewed at his mother’s
    home by Special Agent Fielder. During the last twelve minutes of the interview,
    Davis was told by Agent Fielder that his shorts from the morning of Durben’s death
    had blood from Durden on them and that “this type of blood . . . is basically
    indicative of high velocity spatter. . . . And basically, the only way for her blood in
    that manner to get on your shorts is for you to be in the room when it happened.”
    Davis was asked multiple times if he was in the room when the gun went off. Davis
    maintained that he was not.        Towards the conclusion of the interview, Davis
    responded to a question of whether he may have blocked the memory out, and he
    responded that “I mean I . . . I don’t . . . I don’t believe I was in the room. Like I
    said before, I told you guys . . . .”
    The trial court, in part, relied on this statement by Davis in its verdict. Davis
    argues that his statements were prompted by illegally seized evidence making
    them “fruits of the poisonous tree” and should have been excluded as a part of the
    suppression ruling on his clothing. At trial, much of the audio and visual evidence
    submitted was not published in court. It appears inadmissible evidence contained
    in the exhibits was not physically redacted before submission. Davis alleges that
    trial counsel’s failure to redact the statements in the exhibits constituted ineffective
    assistance of counsel. We disagree.
    24
    At trial, the parties agreed, in an effort towards expediency, that redaction
    of the evidence was unnecessary, as the judge would not consider inadmissible
    evidence. In his PCR brief, Davis acknowledges, “It is commonplace for attorneys
    on both sides of a criminal matter to be collegial. An attorney cannot be faulted for
    working cooperatively with opposing counsel to make a favorable deal or even to
    keep the door open for future discussions.”        When the audio recording and
    transcript of the interview was submitted into evidence, defense counsel objected,
    asking the court not to consider “officers’ statements, any prior bad acts, and so
    forth that we already laid out for the court.” The court received the evidence
    “subject to [the] objection regarding any inappropriate hearsay or bad acts or prior
    acts not admissible or not proper impeachment.”
    Defense counsel made clear its objection to any inadmissible evidence
    contained in the exhibits. The court, as fact finder, reassured counsel it would only
    consider admissible evidence. While the trial record is unclear as to whether the
    specific statements at issue here were subject to the broader suppression ruling
    on Davis’s clothing, we are confident that the court understood the boundaries of
    its ruling and considered the evidence accordingly.10 It is reasonable for defense
    counsel to presume the court is competent to fulfill its duties in accordance with
    the law and only consider admissible evidence. We find, in this bench trial, counsel
    did not have an essential duty to physically redact certain portions of exhibits after
    seeking multiple assurances from the court concerning the scope of the
    admissibility of the evidence, particularly in the absence of a jury.
    10The trial court’s ruling on the motion to suppress was orally pronounced into the
    record on the morning of trial; a written ruling was not filed.
    25
    E.     Counsel’s Lack of Alternative Crime Scene Expert Witness
    Davis contends that investigators mishandled the scene of Durben’s death.
    He points to several alleged processing errors, including failure to record core body
    temperature, the absence of scaled blood-splatter photos, and lack of gunshot
    residue testing.   In preparation for his PCR proceedings, Davis retained and
    deposed his own crime-scene expert, Kenneth Moses. In his deposition, Moses
    explained how the alleged deficiencies of the crime-scene processing limited what
    could be derived from subsequent reconstruction efforts at the time of trial and
    concluded that he believed Durben might have accidentally shot herself. Davis
    argues that trial counsel’s failure to investigate and secure a crime-scene expert
    who could generate a record of testimony regarding the alleged deficiencies
    constitutes a breach of an essential duty. We disagree.
    Counsel has a duty to investigate. However, this duty is not limitless and
    “does not require that counsel pursue every path until it bears fruit or until all
    conceivable hope withers.”     Schrier, 
    347 N.W.2d at 662
     (quotations omitted)
    (citation omitted). “The extent of the investigation required in each case turns on
    the peculiar facts and circumstances of that case.” 
    Id.
     Counsel believed that the
    circumstances of the trial and experience of the judge made hiring their own expert
    unnecessary. Defense counsel explained,
    Once the decision was made to do a bench trial, some of those things
    [hiring an expert] were not going to be done, especially in light of it
    being Timothy O’Grady. He was an experienced criminal attorney
    himself and had tried many cases over the years, both in bench and
    jury trials.
    He explained the judge “had a wealth of knowledge in [crime-scene processing]
    and would understand that the police officers did many things wrong and would
    26
    take those into consideration.” Another defense counsel explained they did not
    hire an independent expert because they “did not believe [the State] would be able
    to present [their case] as well as they could if they were given more time,” and
    because the evidence left room for reasonable doubt, “we felt we could move
    forward with what we had.”
    In Davis’s case, the initial crime-scene processing occurred almost five
    years before trial. Defense counsel’s strategy was to demand a speedy bench
    trial. Based on the crime-scene evidence, the State was unable to rule out the
    possibility of suicide. Defense counsel effectively cross-examined the State’s
    firearms expert Victor Murillo. On cross-examination of Dr. McLemore, defense
    counsel effectively pointed out the lack of gunshot residue and fingernail testing.
    Additionally, he elicited testimony explaining how the failure to record body
    temperature and room temperature made it difficult to determine the time of death.
    Davis has not shown his counsel was ineffective for not hiring an
    independent expert witness. See 
    id.
     at 661–63 (finding counsel not ineffective for
    failing to commission independent scientific testing or draw favorable inference
    from State’s failure to conduct such tests). Counsel competently demonstrated the
    alleged deficiencies in processing and acted consistent with their trial strategy.
    Further, Davis has not proven that had an expert witness been called, it would
    have sufficiently altered the outcome of his trial.
    IV.    Discussion—Pro Se Arguments.
    We now turn to the arguments raised in Davis’s pro se brief not previously
    addressed.    Through his pro se brief, Davis contends that (1) prosecutorial
    misconduct resulted from investigators improperly supplying allegedly false
    27
    information to Dr. McLemore; (2) that Dr. McLemore’s testimony violated State v.
    Tylor, 
    867 N.W.2d 136
    , 162 (Iowa 2015); (3) his trial counsel was ineffective for
    not seeking a suppression hearing in regards to his polygraph interview; and
    (4) inadmissible evidence of his prior bad acts was introduced at trial.
    A.     Prosecutorial Misconduct
    Davis alleges trial counsel was ineffective for failing to assert a prosecutorial
    misconduct claim. Davis claims his right to due process was violated when the
    prosecutor supplied Dr. McLemore with the contested information previously
    discussed. “In analyzing the defendant’s ineffective-assistance-of-counsel claim,
    our first step is to assess whether the record demonstrates . . . a meritorious due
    process violation. Thus, we must consider whether the prosecutor was guilty of
    misconduct . . . and whether the record shows [the defendant] was prejudiced, i.e.,
    denied a fair trial.” State v. Graves, 
    668 N.W.2d 860
    , 869 (Iowa 2003). As noted
    earlier, the autopsy report containing the contested information was not admitted
    as evidence in the criminal trial, and the medical examiner did not testify to blood-
    splatter evidence. Defense counsel cross-examined the medical examiner about
    the lack of suicide information supplied. We find no breach or prejudice. “[I]t is the
    prejudice resulting from misconduct, not the misconduct itself, that entitles a
    defendant to a new trial.” 
    Id.
     (quotations omitted). In the absence of a meritorious
    claim, counsel cannot be ineffective for failing to raise it. 
    Id. at 870
    .
    B.     State v. Tyler
    Next, Davis claims Dr. McLemore’s testimony violates the ruling in Tyler.
    876 N.W.2d at 162 (stating “when a medical examiner bases his or her opinion of
    cause or manner of death on . . . on information obtained through police
    28
    investigation, such opinions would ordinarily be inadmissible . . . because would
    not does not assist the trier of fact”). This argument is being made for the first time
    on appeal, and we find it unpreserved. We have already addressed his ineffective-
    assistance-of-counsel claim related to the medical examiner’s reliance on
    contested information. Davis has not established sufficient reason for failing to
    raise the issue, and this argument does not change our conclusion that his counsel
    was effective. Tyler was decided in June 2015 and Davis’s trial occurred in
    February 2015. Trial counsel cannot be faulted for failing to raise a holding which
    had not yet occurred. See State v. Liddell, 
    672 N.W.2d 805
    , 814 (2003). Any other
    alleged procedural defect in regard to the autopsy report was not properly
    preserved.
    C.    Polygraph
    Davis argues his trial counsel was ineffective for not seeking a suppression
    hearing on evidence related to his polygraph interview. Davis preserved this issue
    by raising it in his application and motion to enlarge or reconsider. The district
    court considered the claim and denied his application.            Davis argues that
    statements obtained through his polygraph interview violated his Miranda11 rights;
    therefore, defense counsel had an obligation to seek a suppression hearing prior
    to trial to exclude the evidence.
    On July 22, 2009, Davis agreed to submit to a polygraph examination.
    Before the interview began, Davis was given a form that described his rights. He
    was asked a series of questions to confirm that he understood his rights. Davis
    11   Miranda v. Arizona, 
    384 U.S. 436
     (1966).
    29
    read aloud the last paragraph of the form titled “Certification,” which included the
    statement “I wish to continue without an attorney. I am here of my own free will. I
    can now leave this room by merely telling [the polygraph administer] that I wish to
    leave.”     Davis signed and dated the form.      Davis understood his rights as
    demonstrated during the examination—during a particularly accusatorial line of
    questioning, Davis stated that he wanted a lawyer, and the interview stopped. The
    evidence indicates that the examiner apprised Davis of his Miranda and Sixth
    Amendment rights; Davis understood these rights and voluntarily continued with
    the interview. No obvious Miranda violation occurred; therefore, it was not an
    essential duty for counsel to seek a suppression hearing prior to trial to exclude
    the evidence.
    Further, defense counsel competently objected to introduction of the
    evidence. At trial, the polygraph examiner, Steven Peterson was called as a
    witness, and the State sought to introduce a video recording of the interview.
    Defense counsel objected, arguing, “polygraphs cannot be introduced in court.”
    The State responded that they were not admitting any polygraph results, just the
    video recording of the interview. Defense counsel’s objection was overruled.
    Defense counsel requested voir dire of the witness and elicited testimony from
    Peterson that made clear to the court that prior to the interview, Davis had received
    a pamphlet that stated that the results of the polygraph were not admissible in
    court. Defense counsel argued the evidence should not be admitted because
    Davis had agreed to the interview believing it would not be used against him,
    affecting the voluntariness of his statements for the purposes of trial. The court
    overruled defense counsel’s objection and admitted the evidence. We find that
    30
    counsel fulfilled his constitutional duty by objecting to introduction of the evidence
    and making a competent argument to the court.
    D.     Prior Bad Acts
    Lastly, Davis argues, “testimony regarding an arrest of a dismissed charge
    was improperly admitted as clear proof of a prior bad act at trial.” This issue was
    raised on direct appeal as both an evidentiary challenge and alternatively, as a
    claim of ineffective assistance of counsel. Because we found the evidentiary issue
    preserved, we addressed it on direct appeal and found no abuse of discretion. See
    Davis, 
    2017 WL 108278
    , at *8 & n.11.           Therefore, Davis cannot prove the
    necessary breach or prejudice to succeed in his ineffective assistance of counsel
    claim on this basis.
    V.     Conclusion.
    For the above reasons, we affirm the denial of postconviction relief.
    AFFIRMED.
