ballistic testing confirmed that the handguns were the weapons used in a gangland murder that had taken place a few weeks previously, for which Riley had been a suspect. Because of the discovery of the concealed and loaded handguns, along with gang paraphernalia, during the vehicle search, police placed Riley under arrest and searched his cell phone without a warrant. The cell phone search yielded information indicating that Riley was a member of the Lincoln Park gang; evidence included pictures, cell phone contacts, text messages, and video clips. Included in the photos was a picture of a different vehicle that Riley owned, which was also the vehicle involved in the gang shooting. Based in part on the pictures and videos recovered from the cell phone, police charged Riley in connection with the gang shooting. Riley moved to suppress the cell phone evidence at his criminal trial, but the judge permitted the evidence to be included. Ultimately, Riley was convicted and the California Court of Appeal affirmed the verdict. That court ruled that the search incident to arrest doctrine permits police to conduct a full exploratory search of a cell phone (even if the search is conducted later and at a different location) whenever the phone is found near the suspect at the time of arrest. Riley then appealed that ruling to the United States Supreme Court. Arrest of Brima Wurie Brima Wurie was arrested in Boston, Massachusetts in 2007 after police observed him participating in an apparent drug sale. Officers seized two cell phones from Wurie's person, and noticed that one of them was receiving multiple calls from a source identified as “my house” on the phone's screen. The officers opened the phone, accessed its call log, determined the number associated with the “my house” label, and traced that number to what they suspected was Wurie's apartment. They then secured a search warrant for Wurie's apartment and, during the ensuing search, found crack cocaine, marijuana, drug paraphernalia, a firearm, ammunition, and cash. Wurie was subsequently charged with drug and firearm offenses and placed on trial. He moved to suppress the evidence obtained from the search of his apartment, but the trial court denied the motion and Wurie was convicted. Wurie appealed to the First Circuit Court of Appeals, which reversed the lower court's decision on the use of phone-related evidence at his trial. The Circuit Court held that cell phones
