"Like anything else you’re going to have knuckleheads to try to ruin everything and our job is to eradicate the knuckleheads," Sheriff Mike Chitwood told FOX35 Orlando.

The sheriff’s chopper pilot spotted an unconscious man bleeding from his head on the stage and moved in to render aid, authorities told the station. With help from some partygoers, deputies were able to get the man to the helicopter.
