Several people inside the Borderline Bar and Grill in Thousand Oaks, Calif., were also at the Route 91 music festival last October, when gunman Stephen Paddock killed 58 and injured hundreds of others.
Nicholas Champion was among those who survived both shootings and spoke about his experience to CBS News.
In April, Champion spoke about surviving the Las Vegas shooting in an interview with Billboard Magazine.

“Firefighting has been something Ive been interested and wanted to do for a long time. Its something I had been setting myself up for, and then after the event, it really went into overdrive. What I saw and experienced at Route 91 reaffirmed that I want to be a firefighter,” he said.
Another witness of the California shooting, Brendan Kelly, also said he was at the Las Vegas massacre.

Authorities: 13 dead in shooting at California bar
THOUSAND OAKS, Calif. — The mourners gathered to hold hands, to sing and to wonder how one of the safest cities in America could become a killing zone.
Hundreds of people gathered Thursday evening to remember the dozen people shot and killed by a Marine veteran at the packed Borderline Bar & Grill the night before.
It was a scene of horror enacted in many places around the country in recent months, but never before in Thousand Oaks.

Terrified patrons who had gathered for the weekly line dancing and college night hurled barstools through windows to escape or threw their bodies protectively on top of friends as shots erupted. Twelve people were killed including Ventura County sheriffs Sgt. Ron Helus, a 29-year veteran nearing retirement who responded to reports of shots fired and was gunned down as he entered the bar.
"When I told her (his wife) that we had lost her hero, I said to her: Because of Ron, many lives were saved," Dean said. "And she looked at me through her tears and she said: He would have wanted it that way."

The dead also included a man who had survived last years massacre in Las Vegas, Telemachus Orfanos, 27.
"I dont want prayers. I dont want thoughts," his mother, Susan Schmidt-Orfanos, said earlier. "I want those bastards in Congress — they need to pass gun control so no one else has a child that doesnt come home."

"Im super upset that it happened in our home and I feel awful for the families that have to go through this," Merrill said at the vigil. She escaped from the Borderline bar when the shooting began, hurting her knee as she ran onto a loading dock.

“The Cal Lutheran community is filled with sorrow over the violent events that took place last night a few miles from campus in Thousand Oaks.

California shooting: Ex-Marine apparently acted alone, says FBI
The killer, Ian David Long, 28, was a former machine-gunner and Afghanistan war veteran who was interviewed by police at his home last spring after an episode of agitated behaviour that authorities were told might be post-traumatic stress disorder.
Twelve people died when a person opened fire at the Borderline Bar and Grill in Thousand Oaks late Wednesday night. The gunman also died at the scene. More than 20 others were injured in the attack. Heres what we know about the victims so far. This story will be updated as more information is confirmed.
Dressed all in black with his hood pulled up, Long opened fire with a handgun with an illegal, extra-capacity magazine. He shot a security guard outside the bar and then went in and took aim at employees and customers, authorities said. He also used a smoke bomb, according to a law enforcement official who was not authorized to discuss the investigation publicly and spoke on condition of anonymity. He apparently killed himself as scores of police converged on the nightspot.
Many of the estimated 150 patrons at the Borderline dived under tables, ran for exits, broke through windows or hid in the attic and bathrooms, authorities and witnesses said.

Matt Wennerstrom said he instinctively pulled people behind a pool table, and he and friends shielded women with their bodies after hearing the shots. When the gunman paused to reload, Wennerstrom said, he and others shattered windows with barstools and helped about 30 people escape. He heard another volley of shots once he was safely outside.
“Weve all been up watching the news, listening to police scanners, praying, calling our parents,” freshman Pari Cribbins said. She had her arm around another student who was at the Borderline Bar on Wednesday night, but who was too shaken to talk about it.
"All I wanted to do was get as many people out of there as possible," he told KABC-TV. "I know where Im going if I die, so I was not worried."
A video posted on Instagram after the shooting by one of the patrons shows an empty dance floor with the sound of windows shattering in the background. As a silhouetted figure comes through a doorway, the camera turns erratically and 10 gunshots ring out.
Telemachus Orafnoss mother confirmed his death to ABC7. He survived the Las Vegas shooting, according to his mother, before being killed Wednesday night. She called for gun control in response to the shootings.

"I looked him in his eyes while he killed my friends," Dallas Knapp wrote on his post. "I hope he rots in hell for eternity."
Earlier, people stood in line for hours to give blood, although some found it hard to get to the donation site because of a wildfire that erupted not far away and closed down a major freeway.
All morning, people looking for missing friends and relatives arrived at a community centre where authorities and counsellors were informing the next-of-kin of those who died.
Jason Coffman received the news that his son Cody, 22, who was about to join the Army, was dead. Coffman broke down as he told reporters how his last words to his son as he went out that night were not to drink and drive and that he loved him.
It was the nations deadliest such attack since 17 students and teachers were killed at a Parkland, Florida, high school nine months ago. It also came less than two weeks after a gunman massacred 11 people at a synagogue in Pittsburgh.
“Then we hear the shots stop or pause, at that point I knew he was reloading and there was not much he was going to be able to do so I jumped up, looked further down along the back of the bar — it’s all glass.
Democratic Gov.-elect Gavin Newsom, in his first public appearance since winning office on Tuesday, lamented the violence that has returned to California.
Matt Wennerstrom is being hailed a hero after saving at least 30 people during a shooting in Thousand Oaks, Calif., Wednesday night that left 13 people dead by throwing a bar stool through a window so civilians could escape.
"Its a gun culture," he said. "You cant go to a bar or nightclub? You cant go to church or synagogue? Its insane is the only way to describe it. The normalization, thats the only way I can describe it. Its become normalized."
“And then after we had gotten everyone, the few boys that were shuffling people through, we basically jumped out the window and then just pushed everyone down the side along the fence towards the parking lot.”
President Donald Trump praised police for their "great bravery" in the attack and ordered flags flown at half-staff in honour of the victims.
A sheriffs unit and two highway patrol officers responded to the calls for help. Ventura County Sgt. Ron Helus and a patrol officer went in through the front door, at which point Helus was struck multiple times with gunfire. The patrol officer rescued Helus out of the line of gunfire, but Helus later died from his injuries.
Authorities searched Longs home in Newbury Park, about 5 miles (8 kilometres) from the Borderline bar, for clues to what set him off.
Police identified the suspect in the shooting as Ian David Long, 28. He was a student at California State University at Northridge who last attended in 2016, the school confirmed. He was also a U.S. Marine Corps veteran, according to authorities. Police had met with him earlier this year but he wasnt arrested.
"Maybe there was a motive for this particular night, but we have no information leading to that at all," the sheriff said.
Long was in the Marines from 2008 to 2013, rose to the rank of corporal and served in Afghanistan in 2010-11 before he was honourably discharged, the military said. Court records show he married in 2009 and was divorced in 2013.

Authorities said he had no criminal record, but in April officers were called to his home, where deputies found him angry and acting irrationally. The sheriff said officers were told he might have PTSD because of his military service. A mental health specialist met with him and didnt feel he needed to be hospitalized.
