THOUSAND OAKS, Calif. (AP) - UPDATE, 9:00 am: - Authorities have identified the suspect in a mass shooting at a Southern California bar as 28-year-old military veteran Ian David Long.
Ventura County Sheriff Geoff Dean says Long is believed to have killed himself late Wednesday at the Borderline Bar and Grill in the city of Thousand Oaks.
Dean says his department had several previous contacts with the former Marine including a call to his home in April, when deputies found him acting irate and irrationally.
The sheriff says a mental health crisis team was called at that time and concluded that Long did not need to be taken into custody.
Dean says the other prior encounters were a traffic accident and an incident when he was the victim of a battery at a bar.
Long was found dead in the Borderline Bar and Grill after 12 people were shot to death late Wednesday.
UPDATE, 8:00 am : 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.
The official declined to provide any other details, speaking on condition of anonymity for lack of authorization to publicly discuss the investigation.
Authorities and witnesses say the gunman wore dark clothing and didn't say anything as he fired inside the bar. Hundreds of people fled, some breaking windows and jumping out of second-floor windows to escape.
A sheriff says 13 people are dead, including a sheriff's sergeant and the gunman, after a shooting inside a crowded Southern California bar late Wednesday.
Ventura County Sheriff Geoff Dean says sheriff's Sgt. Ron Helus responded to the scene and was shot after he entered the building. He died at a hospital early Thursday.
Authorities did not say how the gunman died.
Dean says about a dozen others were shot and wounded. No other information on the victims was immediately known.
Ventura County Sheriff's Office Capt. Garo Kuredjian said 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. Police said hundreds were inside when the shooting occurred.
The suspect has not yet been identified, but a law enforcement source described him as a 29-year-old man to the Los Angeles Times. The source told the newspaper the man drove his mother’s car to the bar, was armed with a handgun and had some kind of smoke device with him.
Investigators are still working to determine a motive. The FBI is working with local law enforcement on the investigation.
