GOLETA, Calif. (AP) — A drive-by shooter went on a nighttime rampage near a Santa Barbara university campus that left seven people dead, including the attacker, and seven others wounded, authorities said Saturday.The gunman got into two gun battles with deputies Friday night in the beachside community of Isla Vista before crashing his black BMW into a parked car, Santa Barbara County Sheriff Bill Brown said.Deputies found him dead with a gunshot wound to the head, but it wasn’t immediately clear whether he was killed by gunfire or if he committed suicide, he said.A semi-automatic handgun was recovered from the scene near the University of California, Santa Barbara. Investigators know the gunman's name, but Brown said he couldn't release it pending notification of relatives.“We’re analyzing both written and videotaped evidence that suggests that this atrocity was a premeditated mass murder,” Brown said.A disturbing YouTube video posted that shows a young man describing plans to shoot women appears to be connected to the attack, police said. Officials would not say whether the person in the video was a suspect in the shooting.In the video, posted Friday, the man sits in a black car and looks at the camera, laughing often, and says he is going to take his revenge against humanity.
