Las Vegas Security Guard Who Approached Shooter Tells His Story on 'Ellen': 'I'm Going Better Each Day'

"I'm doing better each day, slowly but surely. Just healing mentally and physically," he revealed during what he said would be his only public public comments on what happened.

Campos told Degeneres he remembers walking up one flight of stairs to inspect a room that had an open door on the 32nd floor, but had to call for an engineer since the door to the floor was jammed.

When he got on the 32nd floor, the gunman opened fire, striking Campos in his leg. At the time, the security guard didn't know where the bullets were coming from.

"As I was walking down, I heard rapid fire, and at first I took cover," he said. "I felt a burning sensation. I went to go lift my pant leg up and I saw the blood. That's when I called it in on my radio that shots had been fired, and I was going to say that I was hit, but I got on my cell just to clear the radio traffic so they could coordinate the rest of the call."

As Stephen Schuck, the hotel's maintenance worker, came to inspect the metal bracket, he heard Campos shout to take cover just as the shooter opened fire in the hallway again. Schuck appeared on "Ellen" as well.

"Within milliseconds if he didn't say that I would've got hit," Schuck said. "[The bullets] were passing behind my head. I could feel the pressure."

In what has become the deadliest shooting in modern U.S. history, 58 people were killed and more than 500 people were injured at the Route 91 Harvest Festival in Las Vegas Oct. 1.

"I just want to mention all the people that assisted that night, whether it was metro, the FBI, the community, especially coming together to help everyone in need, the first responders, even the people that got called in to assist in hospital," Campos said. "Everything puts pieces together on how everyone came together to help that night even in the darkest hour."

Both men specifically told DeGeneres they wouldn't accept money from the talk show, but Ellen gave Schuck VIP tickets to meet the Indianapolis Colts and Campos received season tickets for the Oakland Raiders once they move to Vegas. In addition, Shutterfly donated $25,000 to the GoFundMe page dedicated to the victims of the Vegas shooting.
