State v. Messner, 419 P.3d 642

Messner was inside a Dillons store for ~8 hours acting confused and picking at his skin; store employee Sally Hermann called police expressing welfare and safety concerns and said he was possibly "meth'd out" and "in no shape to drive."
Officer Sgt. Mickey Farris followed Messner for about a mile as Messner drove away; Farris observed no traffic infractions and initially stopped the vehicle to "check his welfare."
After a brief conversation in which Messner appeared slow and confused but Farris smelled no alcohol and performed no field sobriety tests, Farris asked for and seized Messner’s driver's license to run a wants/warrants check.
The warrant check revealed a suspended license and an outstanding Wichita warrant; Messner was handcuffed and detained while Farris deployed his certified K‑9, which alerted to the vehicle and led to a search revealing methamphetamine and paraphernalia.
Messner moved to suppress the evidence; the district court denied the motion and convicted him at a stipulated bench trial. Messner appealed the denial of suppression.

Issue	Messner's Argument	State's Argument	Held
Was the stop a lawful public‑safety (community caretaking) stop?	Stop lacked specific articulable facts to justify welfare stop.	Tip from identified store employee justified a welfare check.	Yes — court found facts supported an initial welfare stop.
Did the officer exceed the scope of a welfare stop by seizing Messner’s license and running warrants?	Seizing the license and running warrants exceeded a welfare check and converted the encounter into an investigatory detention without reasonable suspicion.	Such actions were permissible to identify and ensure public safety; alternatively, tip could support investigatory stop.	Held: officer exceeded the scope; seizure and warrant check were unlawful.
Could the welfare stop properly morph into an investigatory stop based on observed behavior?	Messner: observed slow speech/movement insufficient to create reasonable suspicion of criminal conduct.	State: observed behavior plus tip supported further investigation (citing cases allowing extension).	Held: observed behavior did not provide reasonable suspicion; stop could not lawfully morph into investigatory stop.
Can the State raise alternate justifications (e.g., preexisting warrant) on appeal?	N/A (defendant opposes)	State attempted to argue for first time on appeal that an untainted arrest warrant would cure the stop.	Court declined to consider the new argument as abandoned for failure to raise below and to brief properly.
