A law enforcement official says authorities have identified the gunman and the handgun he used to kill 12 people at a Southern California bar.
The official told The Associated Press the man was 29 years old and deployed a smoke device and used a .45-caliber handgun when he opened fire inside the Borderline Bar & Grill late Wednesday in Thousand Oaks, north of Los Angeles.

ORIGINAL STORY (4am) --
A sheriff's captain says at least 11 people -- including a responding deputy -- were shot late Wednesday when a suspect opened fire in a Southern California bar filled with college students.
Ventura County Sheriff's Office Capt. Garo Kuredjian said at a news conference early Thursday that the wounded sheriff's deputy was taken to a hospital. He could not immediately provide information on the extent of the victims' injuries or if any others had been hospitalized.
The sheriff's spokesman says the first reports of shots fired came around 11:20 p.m. at the Borderline Bar & Grill in Thousand Oaks, which is about 40 miles west of Los Angeles.
The bar's website says its hosts "College Country Night" every Wednesday. Witnesses said many of those inside were college students.
