The Gwinnett County police are investigating a fatal car accident that occurred before dawn Thursday on Buford Drive at the entrance lane to I-85 South.

A blue 2000 Honda Accord driven by Daniel Walker, 29, of Buford failed to negotiate a curve and headed straight into a field, striking a tree. Walker was not wearing his seat belt and died on the scene. Investigators believe alcohol consumption may be a contributing factor in the accident.
