Thousand Oaks: At least 12 people were killed, including a policeman, at a bar in Thousand Oaks, California.
At least 200 people were reportedly in the Borderline Bar and Grill during the attack.
Officials say the suspect was found dead inside and has not yet been identified. They still do not know his motive for the shooting.
According to reports, the suspect could use smoke grenades and at least one weapon, described as a semi-automatic pistol by witnesses.
The victim told the local KTLA channel: “We just fell to the ground, we heard a lot of screams. My friend is a DJ, so she cut down the music, we just heard a lot of chaos. ”
Another insider witness, Taylor Whittler, said: “I was on the dance floor, and I heard shots, so I looked around, and then suddenly everyone shouted 'Down!'”
"It was a huge panic, I was trampled, I kind of stayed on the floor until some guy grabbed me and pulled out."
It is reported that people fled from the bar, using chairs to knock out windows.
Sherrif Jeff Dean described the scene inside the bar as "terrifying" and said that "blood is everywhere."
Sergeant Ron Helus, who later died in hospital, tried to enter in the midst of the attack when he was shot several times.
Husband and father, he was a policeman for 29 years and was due to retire next year.
“This is woe for us all, he died a hero, he came in to save lives, save other people,” said Sherrif.
The number of injured is being clarified since many from the site of the tragedy were delivered to hospitals by friends and acquaintances.
