State v. Callahan, 2022 Ohio 4103

Indicted (Mar. 2016) on multiple counts including eight aggravated murder counts and related specifications arising from deaths of three victims; pleaded not guilty initially.
Plea agreement (Dec. 18, 2017): Callahan pled guilty to three counts of aggravated murder and one count of aggravated burglary; remaining counts dismissed; joint sentence recommendation of 66 years to life adopted by trial court.
No direct appeal was filed following sentencing.
Callahan filed a post‑sentence Crim.R. 32.1 motion (July 2021) to withdraw his guilty plea, alleging ineffective assistance, lack of counsel preparation, and actual innocence; sought oral hearing and later sought to supplement/amend the motion.
Trial court denied the motion and request for an oral hearing (Mar. 15, 2022), finding claims barred by res judicata or unsupported (affidavit self‑serving), and alternatively lacking credibility or evidentiary support; Callahan appealed.

Issue	Plaintiff's Argument (State)	Defendant's Argument (Callahan)	Held
Whether trial court abused discretion by denying hearing on motion to withdraw plea	Denial proper because claims could have been raised on direct appeal (res judicata) and Callahan submitted only a self‑serving affidavit without other evidence showing manifest injustice	Court should hold an evidentiary/oral hearing because allegations (ineffective counsel, actual innocence) warranted development of the record	Held: No abuse of discretion; claims barred by res judicata or unsupported; no hearing required
Whether defense counsel was ineffective for failing to request competency evaluation	Issue waived because not raised below; alternatively, no record evidence showed competency hearing was warranted	Counsel ineffective for not seeking competency evaluation before plea	Held: Overruled as waived on appeal; even if considered, res judicata would bar it and record contains no evidence supporting need for competency hearing
Whether cumulative errors require withdrawal of plea	No cumulative errors amounts to constitutional deprivation; each claim fails on its merits or is barred	Cumulative effect of errors (ineffective assistance, hearing denial, trial counsel preparation) deprived him of constitutional rights	Held: Overruled; no individual errors found, so no cumulative error
