30 F.4th 369
4th Cir.2022Background
- Officers stopped Joffrey Perez for an expired temporary tag that Officer Marcel suspected was fictitious; multiple officers including a narcotics detective (Haigler) responded.
- Haigler checked Perez’s license and learned it “should not be good”; Marcel used a laptop to investigate the license while other officers sought registration/VIN; Perez did not provide registration.
- The canine unit was requested early and arrived about 15 minutes into the stop; officers obtained the VIN near the 12-minute mark and learned the plate was fictitious and the car was not registered to Perez.
- After the canine alerted to the driver’s side and trunk, officers searched the vehicle and discovered ~3 ounces of methamphetamine and two firearms; Perez was arrested and the car was to be towed.
- Perez moved to suppress, arguing the officers unconstitutionally prolonged the stop to await the dog sniff and that the district court erred in crediting Marcel despite impeachment; the district court denied suppression.
- Perez conditionally pleaded guilty (reserving the right to appeal the suppression denial) and was sentenced; the Fourth Circuit affirmed the denial of the suppression motion.
Issues
| Issue | Perez's Argument | Government's Argument | Held |
|---|---|---|---|
| Whether officers unconstitutionally prolonged the traffic stop to await a dog sniff | Officers deliberately delayed/license and plate checks to allow canine arrival, abandoning the stop’s mission | The stop reasonably developed into multiple investigations (expired tag, fictitious tag, revoked license); officers’ actions were reasonably related and not unduly long | Affirmed: stop not impermissibly prolonged because inquiries were reasonably related and not completed when the dog arrived; towing meant Perez couldn’t simply leave |
| Whether district court clearly erred in crediting Officer Marcel after impeachment | Marcel’s inconsistent statement on who approached the driver impeaches his entire testimony and undercuts towing justification | District court credibility determinations are entitled to deference; Marcel’s minor inconsistency did not negate his overall credibility or the towing rationale | Affirmed: district court did not clearly err in crediting Marcel; deference to credibility findings upheld |
