You would think that a man who lives in Miami surrounded by water and plays with remote control boats in the water would also know how to live with the water. At the very least, own a life vest.
In the course of the day spent playing with his radio controlled boat in a lake, he decided to hop in an inflatable raft when the toy boat stalled mid lake.
Another toy boat (toy boat, toy boat. Say that three times fast) ran into the inflatable raft, puncturing it. It deflated, sending the man on board, over board.
As he did not know how to swim, he drowned. The detective investigating called it a fluke.
