State v. Partin, 2013 Ohio 2858

Late-night December 10, 2011: 911 callers reported shots fired; neighbor Ferdinand Sneed observed someone firing from a kitchen window and later identified John Partin in court as the shooter.
Police surrounded the house; occupants refused to exit for ~2 hours until SWAT arrived; occupants were arrested; gunshot residue was found on Partin's hands.
Partin was indicted for having weapons while under disability (based on a juvenile adjudication for felonious assault on an officer) and obstructing official business; he pled not guilty and proceeded to a jury trial.
During cross-examination, Sneed read from his prior statement that he “could not make out faces”; it was revealed a detective had shown Sneed photos after the standoff, allegedly only to identify a shirt emblem, but the detective did not follow formal photo-identification procedures nor disclose this to the prosecutor.
Defense moved for a mistrial based on nondisclosure of the photo showing; the trial court denied the mistrial but offered defenses options (e.g., calling the detective) which defense declined; jury convicted on both counts and court sentenced Partin to community control and a suspended term.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether denial of mistrial was an abuse of discretion	State: error could be cured; no material prejudice; other evidence supported ID	Partin: nondisclosed photo showing tainted in-court ID; mistrial required	Denial affirmed — no abuse; no material prejudice; curative measures available and not pursued by defense
Whether jury instruction on using prior juvenile adjudication was plain error	State: instruction limited use to determine legal disability and identity for that limited purpose	Partin: instruction misstated law by telling jury to use prior adjudication to decide "identity of the person who committed the offense" causing confusion	Not plain error — instruction imperfect but, read as whole and with admonitions, not prejudicial; jury presumed to follow instructions
Whether trial counsel provided ineffective assistance by failing to object to instruction	State: counsel’s performance reasonable; no reasonable probability of different outcome	Partin: failure to object was deficient and prejudicial	Denied — Strickland standard not met; no prejudice shown
Whether the photographic showing warranted suppression or other remedy	State: detective acted in good faith to identify shirt emblem; error was inadvertent and curable	Partin: photo showing was an improper identification procedure and nondisclosure undermined ID reliability	Court: error inadvertent; less drastic remedies available; not sufficient for mistrial or reversal
