After Thousand Oaks shooting, picture emerges of a troubled ex-Marine known to authorities
LOS ANGELES - Before he opened fire at a Thousand Oaks bar, killing 12 people Wednesday night, authorities said, Ian David Long was known among former roommates and neighbors in Newbury Park as an ex-Marine who appeared to be wrestling with mental health problems.
Dressed in black, Long, 28, made the five-mile drive from his home to Borderline Bar and Grill, where he tossed smoke bombs and rained bullets on a crowd of 150 to 200 people about 11:20 p.m., law enforcement officials said.
Authorities said Long carried out the attack armed with a Glock 21 .45-caliber handgun, which he purchased legally in Simi Valley but had apparently 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 he turned the gun on himself after the massacre. Officials have not determined Long's motive in the attack.
