• Troubled ex-Marine was known to authorities
Before he opened fire at a Thousand Oaks bar, killing 12 people Wednesday night, Ian David Long was known among his neighbors in Newbury Park as a troubled ex-Marine who appeared to have serious mental health problems, authorities said.
Dressed in black, Long, 28, made the five-mile drive from his home to the Borderline Bar and Grill, where he tossed smoke bombs and rained bullets on a crowd of 150 to 200 people, law enforcement officials said.
Authorities said Long carried out the attack armed with a Glock 21 .45-caliber handgun, which he bought legally in Simi Valley but had appar- ently modified with an extended magazine.
Ventura County Sheriff Geoff Dean said Long was found dead of an apparent gunshot wound in an office inside the bar. Authorities suspect that he killed himself. Dean said officials discussed whether he suffered from posttraumatic stress disorder.
Dean said his department had had several interactions with Long, including a visit to his home in April for a complaint of disturbing the peace. Deputies at the time said Long was irate and acting irrationally, Dean said. They called in mental health professionals to evaluate him, and they concluded that he didn’t need to be taken into custody. Long was the victim of a battery at a different Thousand Oaks bar in January 2015, Dean said.
Neighbor Richard Berge, 77, said Long was known to kick holes in the walls of the ranch-style house on Fowler Avenue where he lived with his mother.
“She’s a very sweet woman, but she had a lot of problems with the son,” Berge said. “I just know he tore the house up.”
On Thursday morning, a green light, commonly used to honor military veterans, in a decorative fixture at the house, illuminated the driveway.
According to the U.S. Marines, Long served between 2008 and 2013 and was a machine gunner. He was stationed in Afghanistan from 2010 to 2011.
He received standard military honors including the Navy Unit Commendation, the Navy Meritorious Unit Commendation, the Combat Action Ribbon and the Marine Corps Good Conduct Medal. In 2011, he attained the rank of corporal. His last post was at Kaneohe Bay in Hawaii.
After leaving the military, Long enrolled in 2013 at Cal State Northridge, where he studied athletic training. He left school in 2016 without graduating, according to the university.
Blake Winnett, a set builder from Simi Valley, said he lived with Long for about two years after they met in 2013. They roomed together in Simi Valley and later in Reseda while Long attended college.
Winnett recalled his former roommate as quiet – almost reclusive, keeping to himself and adhering to routines.
“He wasn’t outgoing or talkative,” Winnett said. “He kept to himself, always had his earbuds in. He went to the gym, went to class, or rode his motorcycle.”
Long was known to keep a handgun at the home he and Winnett shared with a few other roommates. It didn’t strike Winnett, a gun owner himself, as unusual.
