Who would I have to contact to assist the boy who was stripped in public by three girls in Florida?

Did he not know the girls, minding his own business, and got attacked for no reason. Or did they all hang together, prank each other from time to time, and this went a little to far. Those scenarios make a big difference. I'm not going to assume we know all the facts. The fact Mom won't press charges, and the Police called it a prank, suggest there is more to it than we know.
