JENNINGS, LA (KPLC-TV) - Charles Deese, the coroner for Jeff Davis Parish, confirms that Jayce Dupuis - whose body was found in Jennings on Thursday - died from a single gunshot wound to the head.
Jayce Dupuis, 21, was last seen alive early Sunday morning in Jennings.
Crews had been searching by foot and water for Dupuis near the area where the Jeff Davis Parish Sheriff's Office recovered a wrecked truck driven by him the day he went missing.
Police said an unnamed passenger drove the busted truck to that area and attempted to ditch the truck in the body of water.
After five days, authorities found Dupuis' body on Thursday, underneath railroad tracks located between his home and the area where investigators found his truck.
Authorities have also not released any information about the passenger who was with Dupuis on the night of the accident.
There is also no word on whether a gun found near the scene was the gun that was used in the shooting.
The investigation remains ongoing.
