Bullets 'Ricocheting Off the Stage': Country Star Jake Owen Describes Las Vegas Shooting

Las Vegas Concertgoer: 'It Was Like Fish in a Barrel'

Recording artist Kaya Jones was in a nearby bar when a shooter opened fire on the Route 91 Harvest Festival in Las Vegas, killing 50 and injuring more than 400.

The gunman, who has been identified as 64-year-old Stephen Paddock, began shooting at concertgoers with an automatic weapon from the 32nd floor of a nearby hotel before killing himself.

Jones, a former Pussycat Doll, was on stage with Big & Rich before the shooting started.

"For every entertainer, it was just gut-wrenching because the whole point in what we do is to unite people, to bring people together, to get them away from their pain at home," she told "Fox & Friends."

Jones said she thinks "every single performer feels responsibility in some way" for the tragedy.

She revealed there was an FBI agent on his honeymoon at the bar. He was given a gun by someone and stood guard by the door.

Jones said a friend's wife and baby were on the same floor of the Mandalay Bay as the shooter, but luckily they were unhurt, she said.

"Every color, creed, religion was in that audience," Jones said. "There are souls that are gone ... my heart is with their families."
