Johnson City Police say a man died in Gray, Tennessee after his pick-up truck veered off of the road and hit a tree.

Police tell us James Bonsor was not using his seat belt and was pronounced dead at the scene on Carol Creek Road.

A witness told police that Bonsor was driving the speed limit but when he veered, he did not press the brakes or swerve his car to try to stop the crash.

Police believe there is a possibility that Bonsor suffered a medical problem that may have led to the crash.
