Using a smoke bomb and a handgun, the hooded Marine combat veteran dressed all in black opened fire during college night at the country music bar in Southern California, killing 12 people and sending hundreds fleeing in terror before apparently taking his own life, authorities said. The gunman was later found dead at the scene.
"We believe he shot himself", Ventura County Sheriff Geoff Dean said.
"When (he) started to reload, that's when we got people out of there and I didn't look back", Wennerstrom said. "This doesn't happen anywhere else on planet Earth".
Multiple people were seen being led out of the bar by deputies.
The gunman was tall and wearing all black with a hood over his head and his face partly covered, witnesses told TV stations at the scene. 'They broke the window'.

A law enforcement officer said the suspect used a.45-caliber handgun, created to hold a magazine of 10 rounds. It's unclear whether the magazine was legally purchased.
Three of the deadliest mass shootings in U.S. modern history have occurred since October 2017.
People wait in line to donate blood outside LaReina High School after a mass shooting by a lone gunman at a bar in Thousand Oaks, California, US November 8, 2018. He and a California Highway Patrol officer were the first to arrive at the bar just before 11:30 p.m. PST (0730 GMT) to confront the gunman.
No fatalities have been reported and the Ventura County Star said that at least four ambulances were at the scene to treat the victims. Information on the extent of the victims' injuries has not yet been released. Borderline features country music, and Wednesday was "college night" that drew many young people to the bar. Once safely outside, the uninjured hugged and awaited word about those still inside.
A few weeks after the Vegas shooting, the bar held a benefit concert for five people from the area who were killed, and now-eerie social media posts show a number of survivors holding up a "Route 91" sign inside the bar at a six-month anniversary event. "One bar stool and straight through a window", he told reporters.
Police have identified the suspected killer as 28-year-old Ian David Long, a former Marine.More news: Judge loses reelection, so he sets all the defendants free
Dean said Long was known to officers through a minor traffic collision and was a victim of a battery incident at a different bar.
Police have not identified a motive. Dean told reporters that there was no indication the suspect was targeting bar employees. Investigators are working out the details of what transpired, Dean added.
Dean said police had previous run-ins with Long, including a call to his home where he was acting irrationally. A crisis intervention specialist was called to his house and talked to him, but left without taking him into custody, Dean said.
Police on Thursday were searching Long's house in Newbury Park, near Thousand Oaks, where he reportedly lived with his mother.
Helus was on the phone with his wife Karen when he got the call that there was a shooting. That Sheriff's Sergeant died in the hospital. "Thank you to Law Enforcement", the president said in another tweet.
