Takeaway
In short, this case rejects a fixed time limit for Terry stops: a 20-minute detention may be reasonable when officers diligently pursue a prompt investigation and the circumstances, including the suspect's conduct, cause the delay.
DEA Agent Cooke observed a pickup truck with a camper shell and a Pontiac traveling together near the North Carolina coast, an area under surveillance for drug trafficking. The pickup appeared heavily loaded, its camper windows were covered, and the vehicles later sped through a campground road after a marked state patrol car joined the surveillance. Cooke and Officer Thrasher attempted to stop both vehicles.
Sharpe stopped the Pontiac, but Savage's pickup passed between the Pontiac and Thrasher's patrol car and continued down the highway. Thrasher pursued and stopped the pickup. He detained Savage while Cooke, unable initially to contact Thrasher, obtained help from local police to remain with Sharpe and then went to find the pickup. About 15 minutes after Thrasher stopped Savage, Cooke arrived, compared Savage's documents with Sharpe's license, observed that the truck was heavily loaded, and smelled marihuana through the camper window. He opened the camper, found burlap-wrapped bales of marihuana, and arrested Savage, Sharpe, and the Pontiac passenger.
The District Court denied suppression, and the defendants were convicted of possessing marihuana with intent to distribute. The Fourth Circuit assumed that the initial stops rested on reasonable suspicion but held that Savage's approximately 20-minute detention and Sharpe's 30-to-40-minute detention were too long to qualify as Terry stops. It treated the stops as de facto arrests unsupported by probable cause and ordered suppression. After a remand for reconsideration in light of United States v. Ross, the Fourth Circuit again reversed on the detention ground. The Supreme Court granted review and reversed.
