Thirteen people are dead after a shooting at a bar in a Los Angeles-area suburb.
The gunman, identified as 28-year-old David Ian Long, walked up to the building, shot a security guard, stepped inside, shot several employees, and opened fire inside the bar, Ventura County Sheriff Geoff Dean said.
Long also fired at police officers when they arrived, killing a deputy sheriff identified as Sgt. Ron Helus, Dean told reporters on Thursday morning. Helus died in a hospital.

Long, the shooter, was a 28-year-old veteran of the US Marine Corps. He used a Glock 21 .45-caliber handgun, Dean said.
Authorities believe he shot himself. They have not found a motive.
Up to 15 other people were injured and taken to hospitals, Dean added. The names and identities of the victims have not been released.

The shooting began about 11:20 p.m. PT at the bar, which is in Thousand Oaks, a suburb about 45 miles northwest of Los Angeles.
The gunman had been “down with a gunshot wound” when officers entered the building, Dean said, adding that there was “blood everywhere.”
Some witnesses described seeing a smoke grenade go off, but Dean said officers did not find any such devices in the bar.
Video footage showed police officers standing outside the bar for up to an hour after their initial arrival. Other footage showed civilians carrying out injured people from the bar and tending to them.
Officers from the FBI Joint Terrorism Task Force and the Bureau of Alcohol, Tobacco, Firearms and Explosives went to the scene.
