RedactedNarrative: On March 25, 2019 at approximately 1:45 p.m. Lt. and I, Senior Agent, responded to a boating incident at Dubuisson Lake in St Landry Parish. Subject was preparing to load his 14 foot Alumacraft vessel (LA9947 FY) with a 24 HP Mercury outboard with tiller steering.  The capacity plate stated the maximum horsepower was 15 hp.  Subject backed away from the dock to line up with his trailer.  While reversing in choppy water (6" - 12" waves), Subject's vessel started swamping, causing the bow of the vessel to rise.  Subject jumped out of his vessel approximately thirty to forty feet from the launch, but he was unable to swim back to land.  Subject's body was recovered and he was not wearing a PFD.  No alcohol and/or drug use was suspected.  There were no other occupants onboard the vessel.
