## Facts

- An officer observed that the license plate on a Lincoln Town Car driven by Marcus Thornton was registered to a different vehicle model.
- Before the officer stopped the car, Thornton parked and exited the vehicle.
- The officer approached Thornton, spoke with him, and obtained consent to search Thornton’s person.
- The officer found two bags of marijuana and a large amount of crack cocaine in Thornton’s pockets, arrested him, handcuffed him, and placed him in the patrol car.
- The officer then searched the Lincoln’s passenger compartment incident to the arrest and found a handgun under the driver’s seat.
- Thornton was charged with federal drug and firearms offenses and sought suppression of the handgun as the product of an unconstitutional warrantless search.

## Issues

1. Whether the Fourth Amendment permits a search of a vehicle’s passenger compartment incident to a lawful custodial arrest when the arrestee is a “recent occupant” and the officer first confronts him after he has exited the vehicle.

## Decision

- The Supreme Court affirmed.
- The Court held that the rule authorizing passenger-compartment searches incident to arrest applies to lawful arrests of vehicle “occupants” and “recent occupants,” even when the officer’s first contact occurs after the suspect leaves the vehicle.
- The Court rejected a limitation that would make the search depend on whether the officer initiated contact while the suspect was still inside the vehicle.
- Concurring opinions questioned whether the traditional search-incident rationales justified the breadth of the rule when the arrestee is secured and unable to access the car.
- The dissent argued the decision expanded warrantless vehicle searches beyond the justifications of officer safety and evidence preservation.

## Legal Principles

- A lawful custodial arrest of a vehicle occupant or recent occupant permits a contemporaneous search of the vehicle’s passenger compartment incident to arrest.
- The permissibility of the search does not turn on whether the officer first engaged the suspect while the suspect was inside the car or after the suspect exited.
- “Recent occupant” status depends on the arrestee’s temporal and spatial relationship to the vehicle at the time of arrest and search, not on the moment of initial police contact.
- The search-incident doctrine is justified by concerns for officer safety and preservation of evidence; some Justices would limit vehicle searches incident to arrest to circumstances where it is reasonable to believe the vehicle contains evidence of the offense of arrest.

## Conclusion

The Court held that, following a lawful custodial arrest of a person who has recently occupied a vehicle, police may search the vehicle’s passenger compartment incident to arrest even if the officer first confronted the person only after the person exited the vehicle.
