The gunman who killed 12 people last week at a Southern California bar died from self-inflicted gunshot, an autopsy has found.
The Sheriff announced the results on the autopsy on 28-year-old former Marine Ian David Long who went on a shooting rampage on Wednesday night at the country music Borderline Bar and Grill.
Police say when Long was inside the bar, he apparently stopped shooting and posted to Instagram, based on the time stamps of the posts.
Long, a former machine gunner who served in Afghanistan, opened fire with a handgun during college night at the bar, then killed himself as scores of police officers closed in.
As investigators worked to figure out what set him off, President Donald Trump blamed mental illness, describing the gunman as "a very sick puppy" who had "a lot of problems".
Several people who knew Long a decade ago as a high-schooler in the suburb of Thousand Oaks said in interviews that he made them uncomfortable, sometimes through aggressive behaviour.
