Thousand Oaks bar shooter had 5 unused high-capacity magazines

Investigators say the number of victims from the mass shooting at the Borderline Bar and Grill in Thousand Oaks this month could have been much higher based on the amount of ammunition the gunman carried.

But authorities said they were no closer to figuring out why 28-year-old Ian Long killed 12 people than they were the day of the Nov. 7 attack.

Investigators said at the first news conference since the week of the shooting, there’s no evidence Long was radicalized or that he was targeting an ex-girlfriend at the bar. Officials had said they were looking into the possibility that he was targeting her.

Long, who killed himself, posted on social media about whether people would think he was insane.

Ventura County Sheriff Bill Ayub says he fired more than 50 rounds during the shooting, using a .45-caliber semiautomatic pistol, but he had seven 30-round high-capacity magazines with him. Five of those magazines, or 150 bullets, hadn’t been used. Such magazines are illegal to buy and possess in California but can easily be purchased in neighboring states.

Ayub also revealed that Long had a folding knife with him and a coroner's official said one victim had been stabbed in the neck, in addition to having several gunshot wounds.

Ayub says attached to Long's gun was a flashlight with a laser sight and Long threw multiple smoke grenades into the crowd during the shooting which contributed significantly to the chaos and confusion inside.
