Gunman who killed 12 died from self- inflicted gunshot

THOUSAND OAKS, Calif. — An autopsy determined that the gunman who killed 12 people at a Southern California bar died from a self- inflicted gunshot, police said Saturday.

Ian David Long, a 28year- old ex- Marine machine- gunner, shot and killed 11 people at the Borderline Bar and Grill in Thousand Oaks and a police officer who responded just before midnight Wednesday. The officer exchanged gunfire with Long, who was found dead at the scene.

Ventura County Sheriff Bill Ayub said an autopsy determined Long fatally shot himself.

Authorities have yet to determine a motive and are exploring all possibilities. Among them is whether Long believed a former girlfriend might have been at the bar, which was filled with about 150 people on its popular college night that attracts students from several nearby schools.

Former Sheriff Geoff Dean, whose last day on the job was Friday, said investigators believe Long targeted the bar but don’t know why. At least a halfdozen people interviewed by The Associated Press who described themselves as regulars at the bar don’t ever recall seeing Long there.

Authorities described an attack of military efficiency. When Long shot his .45caliber pistol, he killed. All of the injured suffered cuts, bruises and other minor injuries in frantic attempts to escape the gunfire.

Based on time stamps, investigators say, Long posted to Instagram during the attack. The post involved his mental state and whether people would believe he was sane.
