955 F.3d 825
10th Cir.2020Background
- At 1:45 a.m. Utah trooper stopped Mayville for speeding (71/60). Trooper observed the driver hunching and acting slow/confused and the driver could not produce registration.
- Trooper Tripodi asked dispatch to run license/warrant checks and a Triple I (Interstate Identification Index) criminal-history check; he also requested a narcotics detector dog. Tripodi continued filling out citation paperwork while waiting for responses.
- A second trooper arrived with a dog; after Mayville initially refused, he was ordered out, patted down, and the dog performed a free-air sniff. The dog alerted to narcotics about 19 minutes after stop began.
- Search revealed methamphetamine, heroin, a meth pipe, two guns (one with silencer), and a scale; Mayville was arrested and indicted on drug and firearms charges.
- Mayville moved to suppress, arguing the Triple I check and related conduct unlawfully prolonged the stop in violation of Rodriguez v. United States; the district court denied suppression (also found reasonable suspicion of impairment as an alternative). Mayville pled guilty reserving appeal; Tenth Circuit affirmed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether running a Triple I criminal-history check through dispatch unlawfully extended the traffic stop beyond its mission under Rodriguez | Tripodi’s Triple I request was unrelated to the speeding stop and unlawfully prolonged the detention to enable investigation of unrelated crimes | Running a criminal-history check is a negligibly burdensome officer-safety precaution; using dispatch was reasonable given out-of-state license and limited in-car database | Court held the Triple I check was a permissible safety-related inquiry and did not unreasonably prolong the stop. |
| Whether the dog sniff and subsequent search were fruit of an unlawful seizure | Dog sniff occurred after an unlawful extension and thus any evidence seized must be suppressed | The sniff occurred contemporaneously with diligent completion of the stop’s tasks (and dispatch’s response) so evidence was admissible | Court held the sniff and search were contemporaneous with a reasonably diligent stop, so suppression was not warranted. |
