There's no word on motive yet, just grim facts: Curtis Adams, a 21-year-old active-duty sailor pulled over after 2am Saturday to help what he perceived to be a stranded driver in Mountain View, Calif. San Diego police said the Good Samaritan was "immediately shot" upon exiting his car, reports the Times of San Diego. Police have arrested a suspect in the shooting: Brandon Acuna, 21. He faces charges of first-degree murder and second-degree burglary.
NBC San Diego reports Adams was in the car with his girlfriend heading southbound on Interstate 15; she called 911 around 2:20am to report the shooting. The car Acuna was in promptly took off, and he was later apprehended when the California Highway Patrol sighted the car and alerted San Diego police. Police say that 10 minutes before allegedly shooting Adams, Acuna shot at a man in Mount Hope who saw him trying to break into his car. (Tragedy for these twins who tried to help a driver.)
