State v. McGuire, 2018 Ohio 1390

On March 16, 2016, David McGuire shot his cousin (Mac) in the legs/groin outside McGuire’s East Cleveland residence; Mac later died from gunshot wounds.
McGuire was indicted on aggravated murder, murder, felonious assault, and having weapons while under disability; firearm specifications were attached to Counts 1–3.
During trial, defense learned two responding officers wore body‑worn cameras but no footage was produced; the East Cleveland Police Department could not locate the recordings.
Defense also discovered during trial that Officer Kenneth Bolton (first responder) was under investigation for unrelated misconduct; defense argued the state failed to disclose impeachment material about Bolton.
The trial court denied mistrial motions but gave a jury instruction permitting adverse inferences from the State’s failure to preserve/provide the body‑camera recordings; jury convicted on all counts and specifications.
On appeal McGuire argued Brady/Giglio violations based on (1) nondisclosure of Bolton investigation and (2) loss/nonpreservation of body‑camera footage; the court affirmed convictions and sentences.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether nondisclosure of an unrelated investigation into Officer Bolton violated Brady/Giglio	State: No Brady violation because information was publicly available and Bolton was not called as a witness	McGuire: Failure to disclose impeachment material about Bolton deprived him of fair trial	Held: No Brady/Giglio violation — information was publicly accessible (defense discovered it) and Bolton did not testify, so impeachment disclosure obligations did not apply
Whether loss/nonpreservation of body‑worn camera footage violated due process (Brady/Youngblood line)	State: Could not disclose what it did not possess; prosecutor made efforts to obtain footage	McGuire: Footage could have shown a different body position and supported self‑defense; loss prejudiced his defense	Held: No due‑process violation — defendant did not show bad faith by police in failing to preserve footage and could not show materiality or prejudice given medical/expert and testimonial evidence inconsistent with self‑defense
Whether the cumulative effect of both alleged failures warranted relief (mistrial or reversal)	McGuire: Combined nondisclosures undermined confidence in outcome	State: Issues are distinct and neither individually nor cumulatively meet Brady/Youngblood standards	Held: Cumulative argument rejected; court considered issues separately and affirmed conviction
