RedactedNarrative: On Friday, September 16, 2016, at approximately 12:50 hrs, a 911 call was received by St. Tammany Parish Sheriff's Office regarding a possible human body floating in Lake Pontchartrain just east of the Lake Pontchartrain Causeway bridge near mile marker#13. At approximately 13:51 hrs, the St. Tammany Parish Sheriff's office special operations division deputies recovered the body of a white male subject, which was found floating face up in Lake Pontchartrain just east of the causeway bridge near mile marker 13. The victim's body was found tangled in rope and fishing line and a type three(3) pfd was also tangled up in the rope on the victim's chest.  The victim's body showed no signs of trauma. A swamped (flooded, but floating in an upright, horizontal position) 14 foot Alweld aluminum vessel (LA xxxx xx) registered to the victim, identified as Victim1 of Pontchatula, LA was found at anchor nearby, between the Causeway spans under turnaround number four. At approx. 16:45 hrs, LADWF agents Sgt#1, Sgt#2, and Sgt#3, arrived at the scene of the swamped vessel(L/L 30 11.988N 90 07 .367W), dewatered and recovered the vessel and brought the vessel to Mandeville Harbor.  It is unknown at this time what caused the vessel to take on water or what circumstances led to the victim entering the water.  There was no alcohol found on the scene, and weather (numerous thunderstorms in the general area) and the size of the victim's vessel could have contributed to this incident. A full autopsy was performed by the St. Tammany Parish Coroners Office Dr#1 on 09-19-2016 at 0900 hrs. The preliminary findings report listed asphyxia due to drowning as the primary cause of the death of Victim1.  Also listed was an enlarged heart and a 75% arterial blockage, as well as mild pulmonary edema.
