Twelve people, including a sheriff’s deputy, were killed after a gunman opened fire at a bar in Thousand Oaks, California, late Wednesday, authorities confirmed early Thursday. The shooter is also dead.
A neighbor who said he knew the gunman who killed 12 people Wednesday night in a shooting at Borderline Bar & Grill told KABC-TV that the suspect lived with his mother and that she was worried about him.
“He wouldn’t get help,” Richard Berge told the news station.
Deputies identified the gunman as Ian David Long, a 28-year-old former U.S. Marine.
Tom Hanson, who lives next door to Long’s mother, told The Associated Press that he called police six months ago when he heard banging and shouting coming from his neighbor’s home.
Ventura County Sheriff Geoff Dean said authorities had made contact with Long before Wednesday’s shooting, including responding to a call to his home in April. Deputies said they found him acting irate and irrationally.
The sheriff said a mental health crisis team was called at that time and concluded that Long did not need to be taken into custody.
Long served in the Marines from August 2008 until March 2013 as a machine gunner. He earned the rank of corporal in August 2011. He also earned several awards during his time in the Corps, including a Combat Action Ribbon and a Marine Corps Good Conduct Medal.
Officials with the Marine Corps said Long was deployed to Afghanistan for seven months, from Nov. 16, 2010, to June 14, 2011. He was assigned to the 2nd Battalion, 3rd Marine Regiment, Third Marine Division in Kaneohe Bay, Hawaii.
Deputies said the 28-year-old former U.S. Marine who opened fire on a crowd gathered Wednesday at Borderline Bar & Grill used a Glock 21 .45-caliber gun that was modified with an illegal extended magazine.
Ventura County Sheriff Geoff Dean said the gun used by Ian David Long was designed to hold a magazine of 10 rounds, with one additional round in the chamber.
