SAN BERNARDINO, Calif. The FBI has not said what it was looking for in a raid early Saturday at the home next door to where San Bernardino shooter Syed Farook’s family used to live in Riverside, California. Neighbors said authorities with guns drawn broke windows and used a cutting torch to get into the garage. A neighbor said an old friend of Farook’s lives in the house. A law enforcement official said that more than three years ago, that person bought two high-powered rifles later used in the shooting. But authorities haven’t been able to talk to him because he checked himself into a mental hospital after the attack. The official was not allowed to discuss the investigation publicly and spoke on condition of anonymity. The FBI has said the man is not a suspect in shootings, though they want to question him.
