A Dunnellon man was killed early Sunday morning in a single-vehicle crash in Crystal River.

The crash happened at 12:29 a.m. on North Citrus Avenue near the intersection of West Red Valley Court.

Troopers say Robert Vance, 47, was driving a 1990 GMC pickup truck north on North Citrus Avenue when, for unknown reasons, he left the road and drove onto the west shoulder.

The pickup truck overturned, and Vance, who was not wearing a seat belt, was ejected from the truck, troopers say.

Vance died from his injuries at the scene of the crash.
