Coroner Karl Addis says 14-year-old Jesse Logan Hannah died at the Oconee Medical Center shortly before 5 a.m. Friday.
Highway Patrol Trooper Billy Elder says Hannah and three other teens were traveling on state Highway 24 when a Westminster police officer tried to pull them over shortly before 3:30 a.m. just east of Westminster.
Elder says the teens drove off and the officer chased them. The car ran off the road and overturned. Hannah and two 16-year-old males were thrown from the vehicle. A fourth teen in the vehicle was not hurt.
There was no word on the condition of the two teens who were hurt.
Addis said an autopsy was planned Friday.
