Victim was in his father's paddle boat fishing about 25 yards North of Dad's dock.  Victim's Mom was on dock.  Victim had PFD on but not fastened.  Victim fell out of the paddle boat and began to swim toward a dock located about 25 yards to the Northeast of where he entered the water.  As he swam, his pfd came off.   Victim had a broken arm and was having trouble reaching dock.  Mother jumped in to try to rescue him but before she reached him, he went under the surface and did not come back up.  Divers located his remains some 3 hours later in about 20' of water and about 20' from neighbor's dock.  Victim had been drinking and had a history of seizures.
