There was a large crowd at the Route 91 Harvest Country Music Festival when gunfire rained down from the 32nd flood of the Mandalay Bay Hotel and Casino on the Las Vegas Strip at about 1 a.m. EST.

Country music star Jason Aldean was performing at the time. Also on stage at the time was Jake Owen, who told CNN Monday morning that he and other performers heard the gunshots and fled the stage and went to their nearby tour bus.

"It was just chaos," Owen said. "People just started scrambling."
