On February 19, 1976, 18-year-old student Neil Jordan "Bishop" Liebeskind opened fire with a sawed-off 12-gauge shotgun at the Computer Learning Center, an independent computer school in Santa Monica. After killing one student and wounding seven others in a classroom, he fled to the parking lot. Security guards for a television crew nearby overheard the shooting, so they ran to the school and ordered Liebeskind to surrender. The gunman instead shot and wounded one of the security guards, so they returned fire and severely wounded him. At his trial, Liebeskind was found not guilty by reason of insanity. He was subsequently sent to a mental hospital.
