RedactedNarrative: On October 13, 2018 at 4:10 pm, I was notified of a boat fire which occurred on the Alabama River approximately 20 miles North of the Selma City Landing in rural Dallas County, AL.  At 5:40 pm I reached the owner of the vessel via telephone.  Subject informed me that at approximately 11:00 am on October 13, 2018 he was jumping off the battery on his Triton 150 bass boat (V1), from his trolling motor battery.  He mentioned he had to jump the battery on his vessel (V1) several times previously that morning.  At this particular instance, he noted after he jumped the battery, he stowed the jumper cables in the rear of the Triton 150 (V1), inside the stern''s storage area.  He then stated he manuevered V1 onto plane and noted smoke coming from under the driver''s console.  He then stated he went back to the stern and opened the compartment where the cables were stowed and noted flames coming from the compartment.  He also stated that subject2 was wearing a PFD during the incident.  He left V1 at the scene where it burned to the water line and sunk.
