One parent told FOX 2 that people were "shocked" that gunfire interrupted the "peaceful" setting.

"I was pretty shocked. I think all of us were. It's horrifying, to think in this peaceful, green setting, the final push of this race - to see and hear that." Fred Ackerman told the outlet.

Ackerman said that despite there being dozens of people around at the teen sporting event, no one spotted the alleged shooter.

"No one saw the shooter," he said. "There were dozens and dozens of people, there were boaters and people walking around on the trail. The police don't know where the shots came from, but they do know it was a gun."
