RedactedNarrative: On the evening of July 20, 2016 at approximately 1800 hours, I, Sgt., was flagged down by a passing motorist in Butte La Rose.  The individual stated that he had just came from Bayou Benoit boat landing and observed a subject who had wrecked his boat and was wanting to fight.  I notified dispatch and headed that direction.  Senior Agent informed me that he was not very far from that area and he would be there when I arrived. 
  
  When we arrived on scene, the overturned vessel was at the landing with the operator nowhere to be found. Shortly thereafter, a female arrived stating that she was looking for her fiancée, who had been involved in a boat wreck.  I ran the numbers on the boat registration and it came back to subject.  As the fiancée and I attempted to located Operator, S/A and bystanders retrieved the sunken vessel, loaded it on a trailer, and towed it to Region IV office.  (The boat, motor and trailer were assigned seizure tag #78952 and logged in as evidence).  I eventually made contact with Operator by telephone.  He stated that he was headed to the hospital so we agreed to meet there.  Operator did not show up at the hospital and numerous phone calls went unanswered.  I eventually located Operator at his residence approximately 5 hours after the incident.  Operator initially was somewhat incoherent due to suspected head trauma.  Operator had a bruise on his left shin and scratch near his right knee.  He was brought to the hospital where he was allegedly diagnosed with a concussion. 
  
  The following day after re-interviewing Operator and investigating the scene of the incident, it was determined that operator was headed west in Grand Bayou in a 15' Stratos.  He failed to negotiate a slight turn to starboard resulting in the port stern quarter of the vessel striking the base of a cypress tree located near the water's edge.  It is believed that after this initial contact, the vessel's bow was redirected hard to port resulting in Operator (who was wearing PFD and kill lanyard) being ejected. 
  
   Some time later, a passing Good Samaritan observed an overturned vessel and Operator standing in waist deep water.  The vessel and Operator were brought to Bayou Benoit landing where Operator apparently hitched a ride to his residence in New Iberia where I eventually met him at approximately 2300 hours.
