The gunman who killed 12 people at a country music bar in Southern California went on social media during the attack and posted about his mental state and whether people would believe he was sane, a law enforcement official said Friday.
Also, one of the possibilities investigators are looking into is whether gunman Ian David Long believed his former girlfriend would be at the bar, the official said.
Authorities have not determined a motive for Wednesday night’s rampage at the Borderline Bar and Grill.
The official was briefed on the investigation but not authorized to discuss it publicly and spoke to The Associated Press on condition of anonymity. The official would not give additional details on what the 28-year-old former Marine posted on his Facebook and Instagram accounts.
A second law enforcement official said that when Long was inside the bar, he apparently stopped shooting and posted to Instagram, based on the time stamps of the posts. Ventura County Sheriff’s Capt. Garo Kuredjian also said he didn’t know the content of the posts.
Neither Facebook nor Instagram responded to a request for comment Friday. Long’s social media accounts have been taken down.
