497 P.3d 832
Utah Ct. App.2021Background:
- Ogden police stopped Antonio Ruiz after a report of a firearm disturbance; Ruiz exited a car parked in an apartment lot and denied weapons on his person.
- Officers conducted an exterior K-9 sniff using Odin; three vehicle windows were partially open by about one foot.
- While walking the dog along the driver-side, Odin paused, changed behavior, dropped to all fours, and spontaneously jumped through the partially open driver window into the car.
- Odin spent ~30 seconds inside, stared at the center console (a trained alert), then exited; officers searched and found rolling papers and a loaded handgun under the driver’s seat.
- Ruiz moved to suppress the evidence claiming a Fourth Amendment violation from Odin’s entry; the district court found the leap was unprompted and denied suppression.
- Ruiz pleaded guilty conditionally, preserving appeal; the Court of Appeals affirmed the denial of the motion to suppress.
Issues:
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether a K-9’s unprompted leap into a car during an exterior sniff violated the Fourth Amendment | Ruiz: Odin’s entry into interior was a warrantless search; officers should have restrained or prevented the dog and training encouraged entry | State: Odin acted instinctively after detecting odor; officers did not open windows or encourage entry so no facilitation occurred | Court: Affirmed. Dog’s entry was instinctive (following scent); officers did not facilitate; search did not violate Fourth Amendment |
