RedactedNarrative: On 12/17/19 at approximately 12:30 a.m., subject  was operating a 14' flat boat. LA-0859-US, with a 25 hp tiller outboard on Pearl River. The vessel had a large amount of rain water accumulated in it from a storm earlier in the night. As subject  accelerated the motor, the was rushed to the stern of the vessel which in turn caused the weighted down stern to submerge in the river. The vessel then capsized and subject was rescued by another boater. All PFD requirements were met and alcohol/drug use is not suspended to be a factor. As of date the vessel is still mostly submerged in the river.
