## Facts

- A Wyoming Highway Patrol officer stopped a car for speeding and a faulty brake light.
- During the stop, the officer saw a hypodermic syringe in the driver’s shirt pocket, and the driver admitted he used it to take drugs.
- The officer developed probable cause to search the car for contraband and searched the passenger compartment.
- The officer searched a purse in the car that passenger Sandra K. Houghton claimed was hers.
- The search of the purse revealed drug paraphernalia and methamphetamine; Houghton was arrested and charged with drug offenses.
- The trial court denied a motion to suppress, reasoning that probable cause to search the vehicle permitted searching any container inside that could hold the sought contraband; Houghton was convicted.
- The Wyoming Supreme Court reversed, holding that when officers know or should know a container belongs to an uninvolved passenger, it is outside the search scope absent a specific opportunity for concealment.
- The U.S. Supreme Court granted review and reversed the state court.

## Issues

1. Whether, when police have probable cause to search a car for contraband, the Fourth Amendment permits a warrantless search of a passenger’s personal container found in the car that could conceal the object of the search.
2. Whether the scope of a vehicle search supported by probable cause depends on container ownership or individualized suspicion of the passenger.

## Decision

- The Court reversed the Wyoming Supreme Court in a 6–3 decision.
- The Court held that officers with probable cause to search a car may inspect passengers’ belongings found in the car that are capable of concealing the object of the search.
- The Court rejected an ownership-based limitation that would exclude clearly identified passenger property from the permissible scope of the search.
- The Court concluded that passengers, like drivers, have a reduced expectation of privacy in property transported in automobiles and that a clear rule allowing container searches better serves effective enforcement.

## Legal Principles

- Under the automobile exception, probable cause to search a vehicle authorizes a warrantless search of containers within the vehicle that may conceal the object of the search.
- The scope of a probable-cause vehicle search does not turn on whether a container belongs to the driver or a passenger.
- The Fourth Amendment does not require officers to determine ownership of containers inside a vehicle as a prerequisite to searching them when probable cause exists to search for contraband.
- Administrative burdens and concealment risks may be considered in assessing reasonableness; a rule permitting searches of all capable containers is constitutionally reasonable under the automobile exception.

## Conclusion

When police have probable cause to search a vehicle for contraband, the Fourth Amendment permits them to search any container in the vehicle that could conceal the object of the search, including containers belonging to passengers, without requiring individualized suspicion directed at the passenger.
