The State of Florida didn't want this released, but the family of the dead kid finally got a judge to order it public.
The kid was only 14 and the 9 guards beat him for over 30 minutes. In the autopsy, there was an apparent totally bogus coverup attempt by saying the kid died of a rare blood disorder that caused his internal bleeding, when in reality it was from the guards pummeling him.
He had complained of breathing difficulties and collapsed while doing push-ups, sit-ups. The guards felt he was being uncooperative so all the guards went after him when he said he couldn't do any more pushups.
Here's the video link. WARNING: Its really nasty on the little kid.
