RILEY v. CALIFORNIA

Opinion of the Court

source identified as "my house" on the phone's external screen. A few minutes later, they opened the phone and saw a photograph of a woman and a baby set as the phone's wallpaper. They pressed one button on the phone to access its call log, then another button to determine the phone number associated with the "my house" label. They next used an online phone directory to trace that phone number to an apartment building.

When the officers went to the building, they saw Wurie's name on a mailbox and observed through a window a woman who resembled the woman in the photograph on Wurie's phone. They secured the apartment while obtaining a search warrant and, upon later executing the warrant, found and seized 215 grams of crack cocaine, marijuana, drug paraphernalia, a firearm and ammunition, and cash.

Wurie was charged with distributing crack cocaine, possessing crack cocaine with intent to distribute, and being a felon in possession of a firearm and ammunition. See 18 U. S. C. §922(g); 21 U. S. C. §841(a). He moved to suppress the evidence obtained from the search of the apartment, arguing that it was the fruit of an unconstitutional search of his cell phone. The District Court denied the motion. 612 F. Supp. 2d 104 (Mass. 2009). Wurie was convicted on all three counts and sentenced to 262 months in prison.

A divided panel of the First Circuit reversed the denial of Wurie's motion to suppress and vacated Wurie's convictions for possession with intent to distribute and possession of a firearm as a felon. 728 F. 3d 1 (2013). The court held that cell phones are distinct from other physical possessions that may be searched incident to arrest without a warrant, because of the amount of personal data cell phones contain and the negligible threat they pose to law enforcement interests. See id., at 8-11.

We granted certiorari. 571 U. S.____ (2014).
