RedactedNarrative: The vessel owner stated that on 10/13/18 at about 2:45 AM, she and subject1 were sleeping, onboard, the listed vessel, (DL 3008 AL, 1977 Marine Traveler), when they were awakened by the sound of the smoke alarm. Owner stated that the vessel was anchored just inside of French Creek, which is just off of the Black Warrior River in Marengo Co. Alabama. Owner stated that she grabbed a handful of items and that she and Subject1 exited the vessel and climbed on board a small dinghy and paddled away. Owner contacted Marengo Co. 911, who in turn contacted Marine Patrol Trooper (Reporting Officer). Trooper responded and found both occupants in the dinghy, holding onto a No Wake Zone Buoy, which was about 40 yards away from the burning vessel. Trooper observed the vessel fully engulfed in flames. Trooper assisted owner and Subject1 in getting into his patrol boat and pulling the small dinghy onboard. Trooper transported both occupants to the Demopolis Yacht Basin (Kingfisher Bay Marina). Trooper returned to the scene of the vessel fire and remained there until the vessel fire was completely extinguished. There was concern about the fire contacting the wooded shoreline, which was about 10 feet away. At approximately 6:00 AM, the fire burned out. The vessel sank in the shallow water, with little of the vessel remaining visible. It was noted that neither Owner nor Subject1 were injured and that Subject1 stated that the fire appeared to have started behind a wall, which contained electrical connections.    Note: Owner and subject1 are both Australian Citizens.
