State v. Oteng, 2020 Ohio 6939

Background

In January 2013 Kingsley Owusu was shot and killed outside the Filipino Center in Columbus; Dennis Oteng was arrested, tried in April 2014, convicted of murder with a firearm specification, and sentenced to 18 years to life.
The prosecution relied largely on witness Benjamin Appiah, while physical evidence was mixed (multiple shell casings from different calibers; .380 casings not conclusively linked to Oteng).
Oteng later filed a postconviction petition claiming his trial counsel, Javier Armengau, labored under an undisclosed conflict (Armengau faced separate criminal indictments) and was ineffective for failing to call Seth Mensah, whose affidavit purportedly exonerated Oteng.
Mensah’s contemporaneous recorded statement to police contradicted his later affidavit: the recording indicated he was inside the party, heard shots, did not see who shot Owusu, and had seen Oteng earlier but not interact with him.
At the postconviction evidentiary hearing Mensah twice failed to appear; the State introduced Mensah’s recorded statement and the lead trial prosecutor testified; Oteng testified about the alleged conflict and failures by counsel.
The trial court denied relief; the appellate court affirmed, holding Oteng failed to show an actual conflict that adversely affected counsel’s performance, and that the court did not abuse its discretion in permitting the prosecutor’s testimony or in proceeding without Mensah.

Issues

Issue	Oteng's Argument	State's Argument	Held
Whether Armengau’s pending indictments created a conflict of interest making counsel ineffective	Armengau’s criminal exposure created divided loyalty; Oteng would not have hired him had he known	Any potential conflict did not demonstrably affect counsel’s actual trial performance	No reversible error; Oteng failed to show an actual conflict that adversely affected performance
Whether counsel was ineffective for failing to call Mensah as an exonerating witness	Mensah’s affidavit asserted he saw the shooters and would have exonerated Oteng	Mensah’s contemporaneous recorded statement contradicted the affidavit; Mensah did not testify at the hearing to resolve the conflict	Trial court reasonably credited record evidence and denied relief because Mensah’s live testimony was absent and affidavit conflicted with earlier statement
Whether it was improper for the prosecutor who tried the case to testify at the postconviction hearing (Prof.Cond.R. 3.7)	Testimony by a government lawyer about opposing counsel violated Rule 3.7 and tainted the hearing	Testimony related to nature/value of legal services and was permissible; rule violations, if any, are disciplinary matters, not automatic exclusion	No reversible error; court permissibly allowed prosecutor’s testimony under rule’s allowances and context
Whether the court abused discretion by holding the hearing without Mensah present	Court should have continued the hearing or compelled Mensah to testify given claimed intimidation	Mensah was deliberately absent, had already caused a continuance, and defense did not subpoena him; proceeding was within the court’s discretion	No abuse of discretion; defense did not take steps to compel Mensah and the court had already continued once
