ST. JAMES PARISH - Police say a man was killed in a freak accident involving a boat and two trucks on a St. James Parish highway.

According to the Louisiana State Police, 49-year-old David Burvant of Slidell was traveling southbound on LA 18 at the time of the crash, around 1 p.m. Monday. Police say a truck towing a boat was traveling in the northbound lane of the highway at the same time. 

For reasons still under investigation, the trailer carrying the boat detached from the vehicle, crossed the center line, and struck Burvant's vehicle. Burvant was wearing a seatbelt, however sustained critical injuries and was taken to an area hospital where he was later pronounced dead.

Police do not believe impairment was a factor in the crash. The accident remains under investigation.
