Background
Police officers conducted surveillance at Aston Park, a public housing development in Asheville, North Carolina, after the property manager reported drug trafficking activity and individuals “walking around with guns.” Officers observed Jermaine Carson arriving regularly as a backseat passenger in a Toyota Highlander driven by Calvin Washington. During a separate joint operation targeting firearm crimes in downtown bars, an officer spotted the Highlander at a gas station and learned Washington’s driver’s license was suspended. Officers coordinated via radio to stop the vehicle before it reached Aston Park, citing safety concerns.
During the traffic stop, four officers arrived sequentially. Agent Corthell initiated the stop and checked Washington’s identification. Officer Hayes arrived next and, at 11:25:52 p.m., detected the odor of marijuana from the Highlander’s rear driver’s side window and observed a knife and digital scale with white residue inside the vehicle. Officer Escobedo arrived last and immediately recognized Carson. When Escobedo attempted to frisk Carson, he discovered Carson’s pants were weighed down. After Carson stated he had a gun, Escobedo recovered a loaded nine-millimeter Glock pistol.
Carson was indicted for possessing a firearm as a convicted felon in violation of 18 U.S.C. § 922(g)(1). He moved to suppress the firearm, arguing that the traffic stop was unlawfully prolonged beyond its lawful mission and that the frisk lacked reasonable suspicion that he was armed and dangerous. The district court denied the suppression motion, and Carson appealed after entering a conditional guilty plea.
The Court’s Holding
The Fourth Circuit affirmed, holding that neither the prolongation of the traffic stop nor the frisk violated the Fourth Amendment. On the traffic stop issue, the court adopted a three-part temporal test: an unlawful seizure occurs when an officer (1) diverts from the traffic-based mission, (2) in a way that prolongs the stop, and (3) the detour is unsupported by reasonable suspicion. The court held that Carson failed on the third prong because Hayes detected the odor of marijuana at 11:25:52 p.m.—providing independent reasonable suspicion to extend the stop—and any alleged “detours” by Corthell occurred either after or contemporaneously with this detection. The court noted that Corthell’s investigative steps, including checking criminal histories and the vehicle’s registration, could not have been completed in the 30 seconds before Hayes detected the marijuana odor.
On the frisk issue, the court held that two requirements under the Fourth Amendment were met. First, officers conducted a lawful stop of Carson as a traffic stop passenger. Second, under the court’s precedent in United States v. Sakyi, when an officer has reasonable suspicion that illegal drugs are in a vehicle during a lawful traffic stop, the officer may frisk occupants for weapons to ensure safety. Because Hayes detected marijuana, Escobedo had reasonable suspicion to frisk Carson, and the frisk was constitutional.
Key Takeaways
- The temporal relationship between police activities and the development of independent reasonable suspicion is critical; alleged traffic stop detours occurring after or contemporaneously with reasonable suspicion do not unlawfully prolong the stop.
- Under Sakyi, reasonable suspicion that illegal drugs are present in a vehicle during a lawful traffic stop justifies a brief frisk of occupants for weapons.
- Judge Berner’s concurrence questions whether the Sakyi presumption linking marijuana use to dangerousness remains valid given the widespread legalization of marijuana in 47 states and the District of Columbia, the FDA’s reclassification of marijuana to Schedule III, and evolving prosecutorial policies.
Why It Matters
This decision provides important guidance on the temporal mechanics of traffic stop extensions, clarifying that detours occurring concurrently with or after the development of independent reasonable suspicion do not require suppression. For law enforcement, the decision validates the Sakyi framework, allowing frisks based on drug suspicion without requiring specific evidence that a particular individual is armed. However, Judge Berner’s concurrence signals potential future reconsideration of the underlying assumption in Sakyi that marijuana use correlates with dangerousness, particularly in light of the FDA’s 2026 reclassification of marijuana and the legal landscape’s dramatic shift toward legalization.
The decision also reflects broader Fourth Amendment tension: while affirming existing precedent, the concurrence highlights how changing federal policy, state law, and social attitudes toward marijuana may outpace precedent established nearly three decades earlier. This could have significant implications for frisk practices and reasonable suspicion analysis in jurisdictions grappling with marijuana legalization.
