State v. Carson, 2019 Ohio 4550

Carson hired a carpet installer, Quincy White, who worked in Carson’s flooded basement; Carson later suspected items were stolen after seeing White and another man near a car with an open trunk.
White left during lunch; Carson allegedly confronted White, then later, according to White, pointed a chrome revolver at him and shouted, causing White to fear he would be shot.
Police body-camera footage captured Carson telling an officer White accused him of pointing a gun; when asked if he owned a gun Carson refused to answer. No firearm was recovered.
Carson testified he did not own a gun, denied threatening White, and asserted White fabricated the gun story to avoid a theft accusation; Carson’s family corroborated his denial of violence and gun ownership.
At trial, the prosecution elicited testimony that Carson had a diagnosis of depression; the court admitted that testimony over defense objection. The court also sustained an objection when defense counsel asked White whether he would lose his job if convicted of theft.
A jury convicted Carson of aggravated menacing (R.C. 2903.21); Carson appealed arguing the verdict was against the manifest weight of the evidence and that the court erred on the two evidentiary rulings.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether conviction for aggravated menacing was against the manifest weight of the evidence	State: White’s eyewitness testimony that Carson pointed a gun and said he would shoot was credible; supervisors corroborated that White reported the incident live	Carson: White lied about the gun to avoid a theft accusation and protect his job; credibility dispute favors Carson	Held: Not against manifest weight—jury reasonably believed White; evidence supported conviction
Admissibility of testimony that Carson had a depression diagnosis	State: Relevant to credibility and to explain purported erratic/paranoid conduct	Carson: Irrelevant, unfairly prejudicial, and improper character evidence without expert linkage	Held: Trial court abused discretion admitting it, but error was harmless—no material prejudice to Carson
Exclusion of testimony that White would lose his job if convicted of theft (motive to lie)	State: Question called for speculation and was properly excluded	Carson: Exclusion prevented showing motive to fabricate the theft-then-gun narrative	Held: Exclusion proper (speculative) and not materially prejudicial—defense elicited other motive evidence
