Jesus Campos is finally telling his story. 

The security guard who was credited with saving lives during the Las Vegas mass shooting had left the public eye after skipped out on several interviews with major tv networks last week. On Wednesday he will appear on the “Ellen Degeneres Show,” to talk about his experience. 

Campos works at Mandalay Bay Resort and Casino and he was the first person to encounter the mass shooter in Las Vegas on the night of Oct. 1.

Campos was doing a security check on the 32nd floor of the hotel when he discovered that a door to one of the stairwells had been jammed. He called Stephen Schuck, a building engineer to take a look at the jam. Schuck also appeared on the show.

Campos was shot in the leg while walking down the hallway by Stephen Paddock, the gunmen who killed 58 people and injured more than 500 who were across the street at a country music concert.

“As I was walking down [the hallway], I heard rapid fire,” Campos said to DeGeneres. “I took cover and I felt a burning sensation. I went to go lift my pant leg up and saw blood. That's when I called in on my radio that shots were fired.”

Campos, 25, did not challenge the police’s timeline of the events in clips released from the show Tuesday. Campos also did not specify times that events occurred in the interview either.

The timeline of events has changed several times since the shooting.

Clark County Sheriff Joe Lombardo initially said that Campos approached the room and was shot while Paddock was firing on the crowd. Police then said that Paddock shot Campos through his hotel door six minutes before he began firing on the crowd. Representatives from Mandalay Bay disputed that timeline Thursday, according to CNN.

On Friday, Lombardo said that Campos was shot around the same time that Paddock began firing into the crowd.

Intrigue around Campos grew Thursday when he skipped interviews to major news networks including Fox News for Sean Hannity’s show, CNN, NBC, ABC and CBS. He had left the public eye, leading some outlets to say he “disappeared.” It added to the mystery of the deadliest mass shooting in modern U.S. history, a shooting in which police have still not determined a motive.

The clips from the show display that Campos is still visibly upset after the incident. He said that going on Degeneres’ show would be the only public interview that he would give.

“I’m doing better each day,” said Campos. “Just healing mentally and physically.”

Campos was able to tell Schuck to take cover when he arrived on the floor and told a hotel guest to also take cover.

“You being shot in the leg saved so many people’s lives,” said DeGeneres. “We just wanted to celebrate you.”

The show will air at 3 p.m. east coast time.
