562 F. App'x 726
10th Cir.2014Background
- Agent Semmerling stopped Westhoven on Highway 80 in southern New Mexico about 40-45 miles from the border after noticing unusual travel patterns and driving behavior.
- Westhoven’s truck had Arizona plates, tinted windows, and a route that suggested avoidance of border checkpoints; she drove through a remote smuggling corridor.
- Agent Semmerling observed a stiff posture, two cell phones, nervousness, and route choices that implied possible smuggling; he conducted a registration check and learned of no warrants but a prior shoplifting conviction.
- Westhoven was detained, asked to step out of the vehicle, and a canine unit sniff was requested; the dog alerted to marijuana in the truck.
- Search of the truck after the sniff recovered marijuana, leading to an arrest and a federal indictment for possession with intent to distribute marijuana; the district court denied suppression and Westhoven pled guilty conditioned on appeal.
- The panel determined oral argument was unnecessary and affirmed the suppression ruling on appeal.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether there was reasonable suspicion to stop Westhoven | Westhoven | Semmerling relied on innocent explanations | Stop supported by reasonable suspicion |
| Whether there was reasonable suspicion to extend detention for a canine sniff | Westhoven | Additional evidence justified detention | Detention for canine sniff was reasonable under totality of circumstances |
| Whether the detention amounted to a de facto arrest requiring probable cause | Westhoven | Detention was investigatory not arrest | Detention was not a de facto arrest; probable cause not required for canine sniff |
