Police say Ian David Long, a 28-year-old ex-Marine machine-gunner, shot and killed 11 people at the Borderline Bar and Grill along with a police officer who responded just before midnight Wednesday.

The video in the media player above is from a previous story.


Police said the officer exchanged gunfire with Long, who was found dead at the scene.

Ventura County Sheriff Bill Ayub said Saturday that an autopsy showed Long fatally shot himself.

Investigators say that based on time stamps, Long posted to Instagram during the attack. The post involved his mental state and whether people would believe here was sane.

Authorities have yet to determine a motive.
