A year ago, 58 people were shot dead at a country music festival in Las Vegas, the worst mass shooting in modern United States history, and several of the patrons in the California bar had also been at the Nevada concert. At least 12 people were killed.
Long reportedly shot a bouncer or security guard outside and forced his way into the bar, witnesses said. "I don't know her name, but (she) is someone I make small contact with and I say hi every time".
Kayla Simmons said she was inside the bar when shots were fired directly behind her. Bullets continued as she managed to escape outside into the parking lot.
Ventura County Sheriff Geoff Dean named the suspect as Ian Long, aged 28.
Helus was one of the first on the scene and was struck multiple times when he went through the front door, the sheriff's office said.
Deputies were called to Long's house in response to a disturbance in April, 2018 and "felt he might be suffering from PTSD", he said.

"I have nothing to believe there is any terrorism link but we will certainly look at that option", he said.
Dean said that officials found a Glock.45-caliber handgun at the scene.
Matt Wennerstron, a 20-year-old college student, said the shooter apparently had a 10-15 round magazine on his gun.
"We have not found any type of assault rifle inside the location", he said.
Investigators have not established a motive for the shooting, and knew of nothing that connected Long to the shooting site.

President Donald Trump said in a tweet Thursday morning that he was "fully briefed" on the shooting. "And that's what's really blowing my mind, it's a really safe area".
But most agree that there was a shooting and many people fled the bar and grill.
