It happened at around 2:30 a.m. on Route 620 in western Fluvanna about a mile north of Route 701. State Police say a 1997 Acura Integra was southbound on Route 620 when it ran off the left side of the road and hit a tree. Police say Keefe was not wearing a seat belt and was thrown from the car. Investigators say alcohol and speed were factors in the crash.
