LITTLE ROCK, Ark. (KTHV) - For Amy Harkins, a girls trip in Las Vegas turned into a total nightmare on Sunday as Stephen Paddock opened fire on an outdoor concert killing 59 people and injuring at least 500 more.

Harkins and her friends were at the Chandelier Bar when the shooting happened.

"There was a pedestrian bridge up there, and we heard people [coming]," she said. "There was a disturbance up there. So we were kind of trying to figure out what was going on."

The next thing she knew, people were yelling that there was a shooter. She said everyone thought the shooter was in their hotel at that point. Everyone began to run, glass flying, and she lost her friends in the chaos.

“The only thing I could imagine that would even be close would be if we had no tornado sirens," Harkins said.

She said she ended up in a stairwell with about 50 other people. She said people were in a daze and fearing for their lives.

"Every time someone would walk up the stairs, or down the stairs, we would all shutter and move, shuffle back and forth," she said.

Harkins and her friends were not harmed during the aftermath, but they discussed cutting their Vegas trip short. They decided against leaving and stayed another night. She said she wouldn't let the fear get the best of them.
