State v. Stonecypher, 508 P.3d 1230

Idaho State Police Cpl. Seth Green stopped Paul Stonecypher’s pickup on I‑90 for equipment/license issues (missing mudflaps, no plates, altered temporary tag).
During the stop (about eight minutes), Green observed furtive movement and noted all three occupants displayed physical signs consistent with recent drug use.
Officer saw a torch lighter and a handkerchief with a rolled item in the cab and a high‑end walkie‑talkie on the visor; the occupants gave a travel story involving visiting a COVID‑sick relative that Green found suspicious.
License/warrant check returned clear; Green persisted in questioning, summoned a K‑9, and the dog alerted to the vehicle.
A search revealed >3.5 lbs marijuana, >200 g methamphetamine, drug paraphernalia, firearms, and ammunition.
The district court denied Stonecypher’s suppression motion (finding reasonable suspicion early in the stop); Stonecypher appealed and the Idaho Supreme Court affirmed.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether extending the traffic stop to allow a K‑9 sniff after license/warrant checks cleared was supported by reasonable suspicion of drug activity	Officer had specific, articulable facts (furtive movement, physical indicators of intoxication, paraphernalia, walkie‑talkie, suspicious travel story) supporting reasonable suspicion to prolong detention	Facts had innocent explanations (torch lighter for cigars, prescription medication side effects, walkie‑talkie nonfunctional); extension violated Rodriguez and the Fourth Amendment	The totality of the circumstances supplied reasonable suspicion to extend the stop for a K‑9 sniff; suppression denial affirmed
