    On brief: Dennis Oteng, pro se.
    APPEAL from the Franklin County Court of Common Pleas
    BRUNNER, J.
    {¶ 1} Defendant-appellant, Dennis Oteng, is presently serving a sentence of 18
    years to life for the shooting death of Kingsley Owusu. Oteng appeals an October 8, 2019
    order of the Franklin County Court of Common Pleas denying his postconviction petition
    following a hearing. We affirm on the merits, finding that, in the absence of testimony by
    a key witness to resolve significant disparities between that witness' recorded statement
    taken soon after the shooting and his later affidavit, the trial court did not abuse its
    discretion in finding that Oteng had failed to establish in the postconviction hearing that
    his counsel's performance was ineffective and therefore unconstitutionally deficient. We
    also find that the trial court did not abuse its discretion in allowing an assistant prosecutor
    to testify at the hearing or in holding the hearing in the absence of the key witness where
    the witness was apparently deliberately absent, where the hearing had already been
    No. 19AP-763                                                                               2
    continued once due to the witness' absence, and where Oteng took no steps to subpoena or
    otherwise compel the witness' presence. We overrule all of Oteng's assignments of error.
    I. FACTS AND PROCEDURAL HISTORY
    {¶ 2} On January 15, 2013, a Franklin County Grand Jury indicted Oteng for the
    murder of Kingsley Owusu. (Jan. 15, 2013 Indictment.) The Grand Jury found probable
    cause to indict on two alternative charges, murder and felony murder, each with a firearm
    specification. 
    Id.
     Oteng pled not guilty on January 18, 2013. (Jan. 18, 2013 Plea Form.)
    {¶ 3} During the month of April 2014, the trial court held a jury trial on the case.
    He was found guilty on all counts, and after merging the felony counts, the trial court
    sentenced Oteng to 15 years to life consecutively with a 3-year gun specification, for a total
    of 18 years to life.
    {¶ 4} Oteng appealed. (June 11, 2014 Notice of Appeal.) On direct appeal, we
    affirmed Oteng's conviction and stated the following to be the facts of the case, based on
    the trial court record:
    In the early morning hours of January 5, 2013, Kingsley Owusu
    was shot and killed in the parking lot of the Filipino Center on
    Westerville Road in Columbus, Ohio. The victim's best friend,
    Benjamin Appiah, described the events that lead to Owusu's
    death as follows. In the late evening of January 4, 2013, Owusu
    and his friend Gab[riel Basoah], also known as G-money,
    picked him up at home and traveled to Lounge 62 in
    Westerville. When they arrived at Lounge 62, they ran into a
    friend by the name of David Aseidu who was at the lounge with
    his friend Andrea d'Almeida. Appiah testified that he and all
    these other individuals hale from the West African nation of
    Ghana. He described the Ghanaian community in Columbus
    as a fairly tight knit group, and he stated that most members of
    the community know each other.
    At Aseidu's suggestion, the group of five left Lounge 62 and
    headed to the Filipino Center to attend a New Year's party co-
    hosted by Appiah's former girlfriend, Alexis Wellington, and
    her best friend, Helen Mamo. According to Appiah, he and
    Wellington had dated "on and off" for approximately one and
    one-half years prior to that time. (Tr. 335.) Appiah was also
    aware that appellant was the father of Wellington's six[-]year[-
    ]old daughter, Michelle.
    When they arrived at the party, [Basoah] parked his vehicle at
    the back of the parking lot. Aseidu, who was traveling with
    No. 19AP-763                                                                       3
    d'Almeida, parked their vehicle closer to the main entrance of
    the Filipino Center. Appiah testified that he exited the vehicle
    and began walking toward the main entrance, just behind
    Owusu and [Basoah]. As [Basoah] and Owusu crossed the
    parking lot, a man by the name of Yaw Boayke confronted
    Owusu and began yelling at him in an "angry tone." (Tr. 353.)
    [Basoah] stepped between the two and then struck Boayke in
    the face with his forehead. The two men fell to the ground
    wrestling before Appiah was able to pull [Basoah] off of Boayke.
    When Boayke returned to the Filipino Center, he was bleeding
    from the mouth, and he told Mamo that [Basoah] had head-
    butted him. By this time, Appiah had entered the Filipino
    Center to check out the party, while [Basoah] and Owusu
    waited outside. Appiah then saw appellant and "his crew" of
    four or five men rush past him toward the parking lot. (Tr. 371.)
    Appiah recognized a man he knew as Daniel, also known as
    D.J., and another man he knew as Stevenson following
    appellant out the main entrance.
    At that point, Appiah went out to the parking lot where he saw
    appellant approaching Owusu with a handgun raised and
    pointed at him. Appiah got between Owusu and appellant in
    an effort to diffuse the situation. When he turned away from
    appellant to face Owusu, he saw that Owusu was holding a
    small handgun. Appiah pleaded with his friend to give him the
    gun. He told Owusu "[l]et's just leave the scene." (Tr. 370.)
    According to Appiah, Owusu handed him the gun.
    At that moment, Appiah heard a [gunshot] ring out behind
    him, and he began running toward the main entrance of the
    Filipino Center to get away. When he reached the entrance, he
    realized Owusu was not with him. Concerned for his friend,
    Appiah turned to head back outside, but he was momentarily
    delayed by a security guard. When Appiah made it outside, he
    saw appellant and Owusu facing one another about arms[']
    length[] apart with appellant pointing a handgun at Owusu.
    Appiah testified that he was standing about ten feet away from
    the two men with a clear view when he saw appellant fire a shot
    at Owusu.
    According to Appiah, the shot struck [Owusu] in the upper
    body, and he immediately fell to the ground. Appellant then
    rushed over to Owusu and began kicking him in the head.
    When appellant broke off his assault and ran, Appiah tried to
    fire a shot from Owusu's gun, but it jammed. Appiah ejected
    two live shells from the gun and then began running after
    No. 19AP-763                                                                           4
    appellant, shooting the gun in the air as appellant fled the
    parking lot in his black BMW.
    Owusu died as a result of a single gunshot wound to the chest.
    Columbus Police arrested appellant on January 6, 2013, at the
    home of his friend Kwame Kusi.
    State v. Oteng, 10th Dist. No. 14AP-466, 
    2015-Ohio-1231
    , ¶ 2-9 ("Oteng I").
    {¶ 5} Subsequently, on Oteng's appeal of the trial court's denial of postconviction
    relief, we again reviewed the entire record and also stated:
    The police recovered a single .380 handgun, two live .380
    rounds, six spent 9 mm shell casings, and two spent .380
    casings at the scene. (State's Ex. A; State's Ex. A-1.) Ballistics
    analysis revealed that two 9 mm casings were ejected by one
    firearm, four 9 mm casings were ejected from another, and the
    two .380 casings were spent by a third weapon. (Tr. at 318;
    State's Ex. S-2.) The .380 casings could neither be excluded nor
    identified as having been fired in the gun recovered at the scene
    (which Appiah testified was the one he used). (Tr. at 317, 320,
    395; State's Ex. S-2; State's Ex. A-1.) That gun also did not fire
    the fatal bullet recovered from Owusu's body. (Tr. at 317, 320;
    State's Ex. S-1.)
    Appiah was the only witness (out of 19 State's witnesses) who
    testified that he saw Oteng shoot Owusu. (Tr. at 375-76.)
    Appiah admitted that he initially lied to the police about
    whether he possessed and fired a gun on the night of the
    shooting. (Tr. at 394-97.) He explained that he lied because he
    was on probation. (Tr. at 396-97.) Although Appiah testified
    that Oteng was standing squarely in front of Owusu when
    Oteng fired, the coroner testified that Owusu was shot in the
    shoulder from the right side at a slightly downward angle. (Tr.
    at 416-20, 469-70.) The coroner explained that the bullet
    passed through the right shoulder at a downward angle into the
    right pleural cavity, passed right to left through the fifth
    thoracic vertebra inflicting a crush injury to the spinal cord,
    then punctured the left lung, and came to rest in the left pleural
    space. (Tr. at 449-50, Autopsy Report at 2, introduced as part
    of State's Ex. P.)
    Basoah, Boayke, and Appiah were all tested for gunshot residue
    ("GSR") the evening of the shooting and all three tested
    positive. (Tr. at 76-77, 104-05, 745-47; State's Ex. R-1.)
    Testimony established that Oteng fled immediately in his BMW
    and the BMW was recovered the next day. (Tr. at 151, 160-63,
    389.) But even though testimony also established that GSR
    No. 19AP-763                                                                       5
    could have been transferred to the car by Oteng's touch and
    even though testimony of an expert suggested that it would
    have lingered within the car until the car was cleaned or driven
    with the windows down, the BMW was not tested for GSR. (Tr.
    at 151, 160-63, 752-55, 788.) Oteng's clothing was tested and
    tested negative for GSR. (Tr. at 762; State's Ex. R-2.)
    Other than Appiah, five lay witnesses testified about the events
    on the evening Owusu was shot. One witness testified that he
    heard the shooting but did not see it. (Tr. at 192-93.) He said
    that he put on his glasses and looked out of his van after he
    heard the shots. 
    Id.
     He saw a man with a gun kicking someone
    lying on the ground but explained that he could not identify
    anyone because it was too dark. 
    Id.
     Another witness, who saw
    the confrontation from about 12 feet away, testified that Oteng
    was the one kicking Owusu in the head as Owusu lay prostrate.
    (Tr. at 255-56, 274.) But that same witness testified that she
    saw both of Oteng's hands during and after the kicking and he
    was not holding a gun. (Tr. at 276-78, 280-82.) Another
    witness testified that both Oteng and Appiah shot their guns
    before Owusu was shot and that she did not know who shot
    Owusu. (Tr. at 553, 570.) A final witness indicated she was
    inside when the shooting happened and did not see any shots
    fired. (Tr. at 638-39.) She indicated that someone she knew as
    "Daniel" or "DJ" screamed to Oteng, "you shot him, get in the
    car." (Tr. at 644, 647-48.) However, she admitted when she was
    initially interviewed by the police in the aftermath of the
    shooting, she told the police at least four times that Basoah was
    the only one who had been shooting a gun and she did not
    mention DJ's alleged exclamation. (Tr. at 697-98, 724-29.) A
    final witness testified that he had warned Oteng not to go to the
    party because he knew Oteng and Owusu were not on good
    terms. (Tr. at 813-14.) He said Oteng telephoned him at 2 a.m.
    on the night of the shooting and said that he had "shot him,"
    which the witness assumed meant that Oteng was confessing to
    having shot Owusu. (Tr. at 816-18.) The witness went on to
    testify, however, that when he saw Oteng in person the next
    evening, Oteng asserted that a lot of people had been shooting
    at the party and that he did not shoot Owusu. (Tr. at 821-23,
    833.)
    On April 24, 2014, a jury found Oteng guilty of all counts.
    (Apr. 24, 2014 Verdict Forms.) During a May sentencing
    hearing, the trial court merged the two murder and felony
    murder counts and sentenced Oteng to serve 15 years to life for
    murder plus 3 consecutive years for the firearm specification,
    No. 19AP-763                                                                                               6
    for a total sentence of 18 years to life in prison. (Tr. at 988, 990;
    May 14, 2014 Jgmt. Entry at 2.)
    State v. Oteng, 10th Dist. No. 18AP-58, 
    2018-Ohio-3138
    , ¶ 4-8 ("Oteng II").
    {¶ 6} In his direct appeal, Oteng raised ten assignments of error. Oteng I at ¶ 12.
    Among other arguments, Oteng maintained that his trial counsel had performed
    ineffectively due to a failure to review certain jail calls, failure to insist on the employment
    of an interpreter to translate jail calls for the jury, failure to object to hearsay testimony,
    and failure to object to improper comments and questions by the prosecutor. 
    Id.
     at ¶ 86-
    92. On March 31, 2015, a panel of this Court overruled all his assignments of error,
    including the ineffective assistance of counsel arguments, and affirmed the conviction. 
    Id.
    in passim.
    {¶ 7} After litigation of a motion for a new trial and an attempted appeal to the
    Supreme Court of Ohio, Oteng filed a postconviction petition and amended postconviction
    petition (together with a motion for leave to amend) seeking to vacate or set aside the
    conviction. (Aug. 17, 2017 Postconviction Petition; Jan. 3, 2018 Am. Petition, attached to
    Jan. 3, 2018 Mot. for Leave.) In these documents, Oteng asserted a single claim, that he
    was deprived of his right to conflict-free counsel when his trial counsel, Javier Armengau,
    represented him despite an undisclosed conflict of interest and when Armengau failed to
    call witnesses necessary to his defense. Specifically, Oteng argued that because Armengau
    had been indicted for several serious offenses,1 Armengau would not have wished to defend
    Oteng vigorously due to a desire to curry favor with the State. (Aug. 17, 2017 Postconviction
    Petition.) Oteng also argued that Armengau failed to call an exonerating witness and
    attached the affidavit of Seth Mensah in which Mensah swore that he personally witnessed
    the shooting. (Mensah Aff., Ex. D., attached to Jan. 3, 2018 Am. Petition.) Mensah averred
    that "[t]he person who shot Mr. Owusu was not Dennis Oteng. I did not even see Mr. Oteng
    with a firearm." 
    Id.
     Mensah stated that the shootout was between "G-Money [Basoah] and
    Ben Appiah" and that Oteng was inside the Filipino Center when the shooting occurred. 
    Id.
    Mensah further averred that he told the police this information and that he had attempted
    to contact Armengau but his contact attempts had gone unanswered. 
    Id.
    1 Armengau was indicted in Franklin County in May 2013 for three counts of kidnapping, one count of public
    indecency, three counts of gross sexual imposition, six counts of rape with specifications, and five counts of
    sexual battery. (Ex. A, attached to Aug. 17, 2017 Postconviction Petition.)
    No. 19AP-763                                                                             7
    {¶ 8} The trial court denied Oteng's initial petition without a hearing and did not
    mention or explicitly rule on his motion to amend his petition or the amended petition,
    itself. (Jan. 3, 2018 Decision & Entry.) On an appeal from that decision, we reversed,
    modified the trial court's decision to grant leave to amend, and remanded so that the trial
    court could reconsider the matter in light of the amended petition and Mensah's affidavit.
    Oteng II at ¶ 28.
    {¶ 9} On remand, the trial court issued a briefing schedule on the amended petition
    and the parties briefed the matter. (Sept. 5, 2018 Briefing Schedule; Sept. 10, 2018 State's
    Memo. Contra; Oct. 3, 2018 Oteng's Reply.) Based on the briefing, the trial court scheduled
    a hearing. (Feb. 5, 2019 Hearing Scheduled.) The trial court continued the hearing once
    on its own motion and once more when Mensah failed to appear to testify. (Mar. 7, 2019
    Continuance; May 22, 2019 Continuance; June 14, 2019 Hearing Tr. at 5, filed Jan. 13,
    2020.) On the third scheduled date, June 14, 2019, the trial court held an evidentiary
    hearing on the petition and amended petition for postconviction relief. (June 14, 2019
    Hearing Tr.)
    {¶ 10} At the outset of the hearing, Oteng's counsel noted that Mensah had, once
    again, failed to appear for the hearing. Id. at 4. Counsel explained that Mensah's absence
    was apparently a deliberate choice by Mensah and that Mensah indicated he had received
    threats from the police. Id. Oteng's attorney did not request a further continuance of the
    hearing on the record or a warrant to secure Mensah's presence, but did request that the
    proceeding "be left open" so that Mensah could provide testimony whenever he might be
    located. Id. The State denied knowledge of any police threats, indicated that the police
    were not looking for Mensah and likely were not even aware of the hearing. Id. at 5. Neither
    the State nor the court expressly addressed on the record Oteng's request that the hearing
    be "left open."
    {¶ 11} Two witnesses ultimately testified in the hearing. The first to testify was
    Oteng. Oteng testified that he hired his trial counsel, Javier Armengau, in 2013 and that
    Armengau did not disclose that he was under indictment. (June 14, 2019 Hearing Tr. at 9.)
    Oteng said that, had he been aware of Armengau's legal situation, he would not have hired
    him. Id. at 9-10. He explained that not until after the trial was concluded, did he become
    aware of Armengau's personal legal troubles and begin to understand, in hindsight, that he
    No. 19AP-763                                                                               8
    had not been represented properly. Id. at 13-14. Specifically, he testified that Armengau
    was ineffective in failing to follow up on Mensah's attempts to contact counsel and in failing
    to call Mensah as a witness at trial. Id. at 19-21. He also added that Armengau made the
    incorrect decision during trial to refrain from calling Oteng's girlfriend as a witness and
    that, had she been called, she would have testified that Oteng had not possessed a gun. Id.
    at 21-23.   However, Oteng also admitted that Armengau cross-examined the State's
    witnesses against him and successfully proved that the witnesses had changed their stories
    about what happened. Id. at 16-17. Oteng also admitted he was unaware that Armengau
    had been prosecuted by the Ohio Attorney General's Office rather than the Franklin County
    Prosecutor's Office. Id. at 12.
    {¶ 12} The second and final witness to testify was the lead prosecutor in Oteng's
    trial. Id. at 24-25. The prosecutor testified that he provided both an audio recording of a
    statement given by Mensah and an informational summary prepared by the interviewing
    officer to Oteng's counsel in discovery. Id. at 25-26. Both recording and summary were
    introduced as exhibits at the hearing. (State's Exs. A-A1.) In the recorded statement,
    Mensah explained that he was at the party for 40 minutes before it was shut down (due to
    the shooting). (State's Ex. A1 at 5:10-5:15, 6:45-6:59.) Mensah said he was inside the party
    and heard the shots but did not know who fired shots. Id. at 5:05-5:42. He stated that he
    saw Oteng at the party, but that they were in different places and he and Oteng did not
    interact that evening. Id. at 7:00-7:22. At some point, Oteng left and Mensah did not see
    him after that point. Id. at 7:00-7:12. The prosecutor admitted that he did not know if
    Mensah and Armengau had communicated.              (June 14, 2019 Hearing Tr. at 31-32.)
    However, the prosecutor stated that it was his observation that Armengau seemed to have
    been "on his game" during the trial and did a good job. Id. at 29-30.
    {¶ 13} On October 8, 2019, the trial court issued a decision denying the petition and
    amended petition for postconviction relief on the merits. (Oct. 8, 2019 Entry.) In its
    decision, the trial court noted that the hearing had been continued once due to Mensah's
    failure to appear and that Oteng's counsel had requested a continuance of the June 14, 2019
    hearing when Mensah again failed to appear. Id. at 2. The trial court noted the lack of
    indication that Mensah had been subpoenaed in denying the continuance and proceeding
    in Mensah's absence. Id. The trial court in its decision recounted the evidence presented
    No. 19AP-763                                                                             9
    in the hearing and concluded that the evidence did not show that Armengau provided
    ineffective assistance to Oteng such that his Sixth Amendment right to counsel would have
    been violated. Id. at 2-7. It therefore denied the petition (and the amended petition) on
    their merits. Id. at 7.
    {¶ 14} Oteng now appeals.
    II. ASSIGNMENTS OF ERROR
    {¶ 15} Oteng alleges three assignments of error for review:
    [1.] The trial court abused its discretion when it denied
    Petitioner-Appellant Dennis Oteng's post-conviction petition
    on insufficient findings on ineffective assistance of counsel and
    a conflict of interest against Attorney Javier Armengau in
    violation of the Fifth, Sixth, and Fourteenth Amendment to the
    U.S. Constitution and Art. 1 Sec. 10 of the Ohio Constitution.
    [2.] The trial court abused its discretion when it denied
    Petitioner-Appellant Dennis Oteng's post-conviction petition
    after sufficient evidence was submitted at an evidentiary
    hearing of Attorney Javier Armengau infectiveness and a
    showing of a conflict of interest which warranted the conviction
    to be vacated.
    [3.] The trial court abused its discretion when the court over
    defense counsel's objection allowed the State prosecutor's
    office to call an assistant prosecutor to testify at the evidentiary
    hearing in violation of Ohio Prof. Cond. Rule 3.7.
    We address the third assignment of error first, resolving the issue of the evidence before
    the trial court before reviewing its conclusions on the evidence.
    III. DISCUSSION
    A. Third Assignment of Error - Whether the Trial Court Abused its
    Discretion in Permitting the Lead Prosecutor in the Trial to Testify
    {¶ 16} "Generally, '[t]he admission of evidence is within the discretion of the trial
    court.' " Shaw v. Underwood, 10th Dist. No. 16AP-605,

    {¶ 17} Oteng argues that the trial court abused its discretion in permitting the lead
    prosecutor in his trial to testify during the postconviction hearing on the topic of
    Armengau's efficacy. (Oteng's Brief at 19-22.) Specifically, he argues that the trial court
    erred in that it permitted the attorney to violate Ohio Rule of Professional Conduct 3.7. 
    Id.
    {¶ 18} Rule 3.7(c) provides, "[a] government lawyer participating in a case shall not
    testify or offer the testimony of another lawyer in the same government agency, except
    where division (a) applies or where permitted by law." Division (a) of the rule states:
    (a) A lawyer shall not act as an advocate at a trial in which the
    lawyer is likely to be a necessary witness unless one or more of
    the following applies:
    (1) the testimony relates to an uncontested issue;
    (2) the testimony relates to the nature and value of legal
    services rendered in the case;
    (3) the disqualification of the lawyer would work substantial
    hardship on the client.
    (Emphasis sic.) Prof.Cond.R. 3.7(a). In this case, a government lawyer (with the Franklin
    County Prosecutor's Office) defending the State in Oteng's postconviction hearing offered
    the testimony of another government lawyer in the same government agency. Prof.Cond.R.
    3.7(c).
    {¶ 19} The Rules of Professional Conduct are not rules of evidence and the authority
    to govern the bar and adjudicate violations of such rules lies solely with the Supreme Court
    of Ohio. State ex rel. Buck v. Maloney, 
    102 Ohio St.3d 250
    , 
    2004-Ohio-2590
    , ¶ 7-8.
    Exclusion is sometimes a proper consideration when, for example, issues of privilege or
    work product are raised (which can also implicate the rules of conduct). See generally
    Squire, Sanders & Dempsey, L.L.P. v. Givaudan Flavors Corp., 
    127 Ohio St.3d 161
    , 2010-
    Ohio-4469. But we have not found any precedent for the proposition that a violation of the
    No. 19AP-763                                                                                     11
    rule at issue in this case should result in an order of exclusion on appeal. In fact, out-of-
    district precedent is to the opposite effect. See State v. White, 4th Dist. No. 19CA715, 2019-
    Ohio-4562, ¶ 32-33.
    {¶ 20} This situation implicates a circumstance where an agency (in this case, the
    Franklin County Prosecutor's Office) is both an advocate for its position and the substantive
    witness in favor of that position. See Prof.Cond.R. 3.7, comments [2]-[5]. However, the
    testimony offered here related to the nature of legal services rendered by opposing counsel
    in the trial that was at issue in the postconviction hearing. Prof.Cond.R. 3.7(a)(2). The
    comments to Rule 3.7 make clear that one of the important considerations underlying the
    rule is the avoidance of confusion for the factfinder. Prof.Cond.R. 3.7, comments. The
    testimony at issue was offered at a postconviction hearing before the trial court in support
    of the professional competence of defense counsel during the underlying trial,
    commensurately reducing the significance of this witness’s testimony.
    {¶ 21} We note that the same factfinder on postconviction relief, the trial court, also
    had the opportunity to observe and evaluate Oteng's counsel's performance during the trial.
    For the purpose of avoiding confusion for the factfinder, we find little to no likelihood of
    confusion in these circumstances.
    {¶ 22} While we do not render a judgment on any alleged violation of Prof.Cond.R.
    3.7(a)(2), based on the rule's purpose and the evidence in the record, we find no reversible
    error in the trial court's permitting the lead trial counsel for the State at trial to testify at the
    hearing on Oteng's motion for postconviction relief about his defense counsel's
    performance at trial. Thus, we overrule Oteng's third assignment of error.
    B. First and Second Assignment of Error - Whether the Trial Court Erred
    in Failing to Find that Armengau was Ineffective Due to a Conflict of
    Interest
    {¶ 23} The Ohio Revised Code provides:
    Any person who has been convicted of a criminal offense * * *
    and who claims that there was such a denial or infringement of
    the person's rights as to render the judgment void or voidable
    under the Ohio Constitution or the Constitution of the United
    States * * * may file a petition in the court that imposed
    sentence, stating the grounds for relief relied upon, and asking
    the court to vacate or set aside the judgment or sentence or to
    grant other appropriate relief.
    No. 19AP-763                                                                                 12
    R.C. 2953.21(A)(1)(a). This postconviction relief process is a collateral civil attack on a
    criminal judgment. State v. Steffen, 
    70 Ohio St.3d 399
    , 410 (1994). "It is a means to reach
    constitutional issues which would otherwise be impossible to reach because the evidence
    supporting those issues is not contained" in the trial court record. State v. Murphy, 10th
    Dist. No. 00AP-233, 
    2000 WL 1877526
    , 
    2000 Ohio App. LEXIS 6129
    , *5 (Dec. 26, 2000);
    see also, e.g., State v. Carter, 10th Dist. No. 13AP-4, 
    2013-Ohio-4058
    , ¶ 15. "If the court
    does not find grounds for granting relief, it shall make and file findings of fact and
    conclusions of law and shall enter judgment denying relief on the petition." R.C.
    2953.21(H). "If * * * the court finds grounds for relief * * * it shall make and file findings of
    fact and conclusions of law and shall enter a judgment that vacates and sets aside the
    judgment in question, and, in the case of a petitioner who is a prisoner in custody, shall
    discharge or resentence the petitioner or grant a new trial as the court determines
    appropriate." 
    Id.
    {¶ 24} Because the trial court is in the best position to view and weigh testimony,
    when we consider a trial court's determinations based on evidence obtained during a
    postconviction hearing, we defer to the trial court's findings and apply an abuse of
    discretion standard. State v. Gondor, 
    112 Ohio St.3d 377
    , 
    2006-Ohio-6679
    , ¶ 46-58. Thus,
    we should not reverse a discretionary finding following a hearing if it is supported by
    competent, credible evidence. Id. at ¶ 58. Yet, as ever, "we note that no court has the
    authority, within its discretion, to commit an error of law." (Citations omitted.) Chandler,
    
    2013-Ohio-4671
    , at ¶ 8; see also Liggins, 
    2016-Ohio-3528
    , at ¶ 18.
    {¶ 25} In this case, the constitutional right Oteng claims was violated was his right
    to counsel under the Sixth Amendment to the U.S. Constitution. (Oteng's Brief at 5-18.)
    Specifically, he argues that although he had counsel, his attorney (Armengau) had a conflict
    of interest that rendered him ineffective. 
    Id.
    {¶ 26} In cases involving the representation of multiple defendants, the Supreme
    Court has stated, "[w]here there is a right to counsel, the Sixth Amendment to the United
    States Constitution also guarantees that representation will be free from conflicts of
    interest." State v. Dillon, 
    74 Ohio St.3d 166
    , 167 (1995), citing State v. Gillard, 
    64 Ohio St.3d 304
    , 312 (1992). Relying on United States Supreme Court precedent, this Court has
    previously held:
    No. 19AP-763                                                                               13
    "* * * Prejudice is presumed when counsel is burdened by an
    actual conflict of interest. * * * Given the obligation of counsel
    to avoid conflicts of interest and the ability of trial courts to
    make early inquiry in certain situations likely to give rise to
    conflicts * * * it is reasonable for the criminal justice system to
    maintain a fairly rigid rule of presumed prejudice for conflicts
    of interest. * * * Prejudice is presumed only if the defendant
    demonstrates that counsel 'actively represented conflicting
    interests' and that 'an actual conflict of interest adversely
    affected his lawyer's performance.' * * *"
    State v. Foster, 10th Dist. No. 90AP-05, 
    1990 WL 174008
    , 
    1990 Ohio App. LEXIS 4911
    , *9-
    10 (Nov. 6, 1990), quoting Strickland v. Washington, 
    466 U.S. 668
    , 692 (1984). More
    recently, the Supreme Court of Ohio has explained, "[i]n order to satisfy a Sixth
    Amendment claim of ineffective assistance of counsel," based on a conflict of interest, a
    defendant "must demonstrate that an actual conflict of interest adversely affected his
    counsel's actual performance." State v. Jackson, 
    149 Ohio St.3d 55
    , 
    2016-Ohio-5488
    ,
    ¶ 102; see also Cuyler v. Sullivan, 
    446 U.S. 335
    , 348-50 (1980).
    {¶ 27} Though Oteng relies on the principles involved in these cases, his argument
    is somewhat different. (Oteng's Brief at 6.) He argues that, although Armengau was not
    engaged in representing another defendant whose interests were opposed to Oteng's,
    Armengau's own legal difficulties were such that a conflict arose. Id. at 6-13. That is, "Oteng
    [has] argued that because Armengau had been indicted for several serious offenses,
    Armengau would not have wished to defend Oteng vigorously due to a desire to curry favor
    with the State." Oteng II at ¶ 10.
    {¶ 28} A pending criminal or ethical case against a defense attorney by the same
    prosecutor's office or in the same jurisdiction as the attorney's client's case, under certain
    circumstances can create a conflict of interest. See, e.g., State v. Dean, 
    127 Ohio St.3d 140
    ,
    
    2010-Ohio-5070
    , ¶ 21-23, 71; United States v. De Falco, 
    644 F.2d 132
    , 133-36 (3d Cir.1979).
    As the Third Circuit put it in De Falco:
    The adversary system of the common law, as distinguished
    from the inquisitorial system of the civil law, is regarded in the
    Anglo-American tradition as the surest method of arriving at
    the truth when facts are disputed, and for discerning the proper
    legal precepts to be applied to those facts. These goals are to be
    achieved by the healthy and forceful presentation of partisan
    viewpoints. Although the ultimate decision is always the
    responsibility of the jury and the judge, our system can prosper
    No. 19AP-763                                                                              14
    only when lawyers, as officers of the court, are able to develop
    the fullest dimensions of the cause being heard. "[The lawyer's]
    principal responsibility is to serve the undivided interests of his
    client. Indeed, an indispensable element of the effective
    performance of his responsibilities is the ability to act
    independently of the government and to oppose it in adversary
    litigation." Ferri v. Ackerman, 
    444 U.S. 193
    , 204, * * *
    (December 4, 1979). If there is any constraint on counsel's
    complete and exuberant presentation, our system will fail
    because the basic ingredient of the adversary system will be
    missing. The essence of the system is that there be professional
    antagonists in the legal forum, dynamic disputants prepared to
    do combat for the purpose of aiding the court in its quest to do
    justice. Therefore, if any circumstance impedes the unqualified
    participation by an attorney, the adjudicatory function is
    inhibited, ultimately threatening the object of that function,
    justice in the cause at hand.
    De Falco at 136. The Third Circuit explained why a pending criminal prosecution against
    an advocate by his adversary sometimes could disrupt that process:
    It is essential that the advocate owe no fealty that conflicts, or
    even appears to conflict, with the paramount ethical loyalty he
    owes his client. The competent advocate must stand tall * * *
    and assert his [or her] client's contentions without fear or favor.
    This is not the posture a defendant in a criminal case assumes
    as he goes, hat in hand, to negotiate a plea bargain with his
    adversary. Nor is it the posture a defendant assumes as he
    appears before the trial court following a plea of guilty to beg
    the mercy of the court before sentence is pronounced.
    
    Id.
    {¶ 29} From the record of Oteng's postconviction hearing it is clear that Armengau
    was prosecuted by the Ohio Attorney General's Office rather than the Franklin County
    Prosecutor. (June 14, 2019 Hearing Tr. at 12.) We note that, regardless of the office or title
    of the legal representative, the party pressing prosecution and whose interests were sought
    to be vindicated by the prosecution, was the State—the same party that was pursuing the
    prosecution of Oteng. State v. Oteng, Franklin C.P. No. 13CR-224; State v. Armengau,
    Franklin C.P. No. 13CR-2217. Moreover, the jurisdiction and venue of both prosecutions
    (Franklin County Common Pleas Court) was the same. In other words, Armengau was
    simultaneously litigating against the State in Franklin County on behalf of Oteng while
    being prosecuted by the State in Franklin County for multiple serious felonies. Thus, it
    No. 19AP-763                                                                                15
    could be possible to argue that Armengau could have experienced a divided loyalty between
    his duty to vigorously represent his client against the State and his personal wish to avoid
    antagonizing either the court (that would conduct his trial and sentence him) or the State
    (which sought to convict and imprison him). It is also undisputed, based on the evidence
    presented during the hearing, that Oteng was not made aware of the possible conflict until
    after the representation was concluded. (June 14, 2019 Hearing Tr. at 9-14.)
    {¶ 30} We need not reach that determination, however, because Oteng could not
    prevail in his Sixth Amendment argument unless he also established that the actual conflict
    "adversely affected his counsel's actual performance." Jackson, 
    2016-Ohio-5488
    , at ¶ 102;
    see also Cuyler, 
    446 U.S. at 348-50
    . Finding no abuse of discretion, we agree with the trial
    court's determination that Oteng failed to meet this burden. (Oct. 8, 2019 Entry at 4-7.) In
    the course of this appeal and prior appeals in this case, we have conducted a thorough
    review of the trial transcript, and we find no testimony or findings of the trial judge that
    would show the trial court abused its discretion in finding that Armengau performed
    effectively in Oteng's trial. Id.; June 14, 2019 Hearing Tr. at 29-30. Even Oteng admitted
    that Armengau cross-examined and managed to prove that each of the State's witnesses
    had altered their stories and had essentially lied. (June 14, 2019 Hearing Tr. at 16-17.)
    {¶ 31} Notwithstanding the evidence of Armengau's generally good performance at
    trial, the facts stated by Mensah in his affidavit if credited could lead to a different
    conclusion on Armengau's representation in that Mensah asserts that he was a potentially
    exonerating witness whom Armengau ignored. (Mensah Aff., Ex. D., attached to Jan. 3,
    2018 Am. Petition.) That is, Mensah in his affidavit asserts that he observed the shooting,
    could identify the shooters, could exonerate Oteng, previously related all of this to police,
    and attempted to relate it to Oteng's counsel:
    On January 5, 2013, I was at the Filipino Center on Westerville
    Road in Columbus, Ohio and observed Kingsley Owusu being
    shot and killed in the parking lot. The person who shot Mr.
    Owusu was not Dennis Oteng. I did not even see Mr. Oteng
    with a firearm. The men responsible for shooting Mr. Owusu
    were two men I knew as G-Money and Ben Appiah. They both
    arrived with Mr. Owusu and had a shootout with other people
    at the Filipino Center. Mr. Oteng was inside the Center when
    the shooting occurred. * * *
    No. 19AP-763                                                                                  16
    After hearing that Mr. Oteng was charged with the crime, I
    attempted to contact his attorney, Javier Armengau, and relay
    the information I knew about the shooting. However, Mr.
    Armengau never returned my messages. I also told police
    detectives this information.
    (Mensah Aff., Ex. D., attached to Jan. 3, 2018 Am. Petition.) However, Mensah's recorded
    statement, obtained near the time of the shooting, contradicts many of his assertions by
    affidavit. The recorded statement reveals that Mensah told the police that he was inside the
    party and therefore only heard, but did not see, the shooting, and did not know who the
    shooter was. (State's Ex. A1 at 5:05-5:42.) The recording also shows that Mensah admitted
    that he saw Oteng at the party, but did not interact with him and then saw him leave. Id. at
    7:00-7:22. While that recorded statement does not present such facts that would make
    Oteng's innocence impossible, it stands in sharp contrast the clearly exonerating assertions
    of Mensah's later affidavit.
    {¶ 32} Rather than appear and offer evidence at the postconviction hearing to
    resolve this conflict and support the claims made in the affidavit, Mensah twice failed to
    appear. (June 14, 2019 Hearing Tr. at 4-5.) The trial court also pointed out that, once the
    hearing was scheduled, Oteng could have subpoenaed Mensah for the hearing under Civ.R.
    45 to require his presence. (Oct. 8, 2019 Entry at 2.) Oteng did not do this. Nor was
    evidence beyond an inadmissible statement by counsel offered to show that Mensah had
    been intimidated by law enforcement into avoiding the hearing. Id.; June 14, 2019 Hearing
    Tr. at 4-5, in passim. Given what was before the trial court: Mensah's conflicting counts of
    the events that led to the death of the victim, Kingsley Owusu, and the fact that Mensah did
    not appear to testify to resolve the conflict and permit the trial court to judge his credibility,
    we do not find an abuse of discretion in the trial court's ruling that Oteng had not proven
    Armengau's performance was adversely affected.
    {¶ 33} Oteng also appears to argue that the trial court acted improperly in failing to
    continue the hearing to allow Mensah the opportunity to appear or to allow the defense the
    opportunity to prove that Mensah was being intimidated by the police. (Oteng's Brief at 15-
    16.) The hearing had already been continued once for the purpose of permitting Mensah to
    appear and the docket does not reflect that any attempt was made to subpoena Mensah for
    the second hearing or take other legal steps to ensure his presence. (June 14, 2019 Hearing
    No. 19AP-763                                                                               17
    Tr. at 4-5; Docket in Franklin C.P. No. 13CR-224.) Under the circumstances, the trial court
    properly acted within its discretion in proceeding with the hearing.
    {¶ 34} We overrule Oteng's second and third assignments of error.
    IV. CONCLUSION
    {¶ 35} The trial court did not abuse its discretion in allowing an assistant prosecutor
    to testify at a hearing on Oteng's postconviction petition or in holding the hearing in the
    absence of a key witness where the record shows that witness was deliberately absent,
    where the hearing had already been continued once due to this witness' absence, and where
    no steps were taken to subpoena or otherwise compel this witness' presence, thus denying
    the trial court the opportunity on postconviction review to see and hear the live testimony
    of the witness in order to resolve the apparent disparity between his recorded statement
    taken soon after the shooting and his later-created affidavit and to judge his credibility. The
    trial court did not commit reversible error in finding that Oteng had failed to establish that
    his counsel's performance was unconstitutionally deficient. We affirm the judgment of the
    Franklin County Court of Common Pleas.
    Judgment affirmed.
    NELSON, J., concurs.
    SADLER, P.J., concurs in judgment only.
