State v. James, 379 P.3d 626

Defendant and his brother (Collins) met victims (Hamm and Schnippel) to buy marijuana; an altercation occurred, Hamm was hit with a stick, phones ended up on the ground, Collins fled with property, and defendant shot Hamm.
Defendant was charged with multiple crimes including first-degree assault with a firearm, two counts of first-degree robbery with a firearm, unlawful use of a weapon with a firearm (UUW-firearm), and felon in possession of a firearm with a firearm (FIP-firearm); jury convicted on most counts and the trial court imposed upward-departure sentences totaling 338 months.
Collins testified for the state under a cooperation agreement; his trial testimony largely matched prior statements to police except he denied at trial that he and defendant went to the park intending to rob the victims, while a detective testified Collins had earlier said they planned a robbery.
Defense objected when the prosecutor elicited testimony that Collins’s agreement required him to "testify truthfully as given to law enforcement," arguing this was improper vouching; the trial court overruled and denied a mistrial request.
Defendant also argued on appeal that UUW-firearm and FIP-firearm convictions should have merged; he did not raise that merger argument at trial and urged plain error on appeal.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Admissibility/vouching: prosecutor questioned witness about cooperation agreement wording	The inquiry did not improperly vouch; any disputed wording did not amount to impermissible state opinion or affect the verdict	The prosecutor’s question conveyed the state’s belief in Collins’s prior statements and improperly vouched for his credibility	Any error (if vouching) was harmless because Collins’s trial testimony largely matched his prior statements and the disputed point (prearranged intent to rob) would not have changed convictions
Merger of UUW-firearm and FIP-firearm	The state maintained the charges were plausibly distinct and included different elements as charged	Defendant argued the two convictions should merge under ORS 161.067(1) because they arose from a single criminal episode and overlapped in elements; urged plain error	No plain error: merger not required because it was not beyond dispute that the offenses, as charged, lacked differing elements; conviction and sentences affirmed
