United States v. Ross
United States Supreme Court
456 U.S. 798 (1982)
Acting on an informant's tip, D.C. police stopped and searched Ross's (defendant's) car, finding a bullet on the driver's seat and then a gun in the glove compartment; after arresting Ross, officers opened the trunk with his keys and found a brown paper bag containing what appeared to be drugs, and a later station-house search of the trunk uncovered a zippered leather pouch containing cash. Ross moved to suppress the contents of both containers; the trial court denied the motion and he was convicted, but the en banc court of appeals reversed, vacating the conviction based on greater privacy expectations attached to the containers.
Whether a police search of closed containers discovered inside a vehicle during a warrantless vehicle search violates the Fourth Amendment when probable cause justifies a search of the containers.
