Gardner, 22, was shot early Sunday morning as he sat in the passenger seat of a friend's Infiniti after the friend honked his horn at a Chevrolet Tahoe that was being driven erratically on Interstate 380 in San Bruno, California Highway Patrol investigators said.
Somebody in the Tahoe responded to the beep with a burst of gunfire, investigators said. One of those bullets tore through the back of Gardner's seat and into his head, according to his mother, Karen Gardner, who on Monday made the decision to end life support and donate her son's organs.
