State v. Ilk, 422 P.3d 1219

On April 15, 2015 Michael Ilk shot Hadassah Pereslete and Tyler Wilson; both survived with serious injuries. Ilk was arrested shortly after at the police station.
Ilk claimed self-defense; the State presented eyewitness testimony, physical evidence (multiple 9mm casings and extensive bullet damage to Wilson’s truck), and argued Ilk fired into the truck while windows were closed.
Defense pointed to a single .45 casing at the scene, gaps in the State’s forensic work, and complained the State failed to produce daytime crime-scene photos Detective Rhodes said he likely took a day or two after the shooting.
District Court instructed the jury with conduct-based definitions of the mental states “knowingly” and “purposely” rather than result-based definitions applicable to Attempted Deliberate Homicide and Aggravated Assault.
Jury convicted Ilk of two counts of Attempted Deliberate Homicide and two counts of Aggravated Assault. Ilk appealed, arguing erroneous jury instructions and a Brady violation for nondisclosure of the photographs.

Issue	Ilk's Argument	State's Argument	Held
Whether giving conduct-based definitions of "purposely" and "knowingly" was reversible error	Instruction lowered State’s burden for result crimes and prejudiced Ilk	Court should give conduct instructions; prosecutor at times argued in result-terms	Error to give conduct-based definitions, but harmless; conviction affirmed
Whether failure to disclose Rhodes’ daytime photos violated Brady	Photos were favorable, suppressed, and likely would have changed outcome	Photos may not exist; if they did they would have been in State’s open file and not outcome-determinative	Assuming photos existed and were suppressed, nondisclosure was not material; no reasonable probability of a different outcome
