OCALA, Fla. -

Authorities say a 15-year-old girl is dead following a crash while racing at Bubba Raceway Park near Ocala.

Niokoa Johnson was injured Saturday evening while driving a race-ready Nissan Sentra. She died Sunday after being flown to UF Health Shands Hospital in Gainesville.

Marion County Sheriff's officials say this was Johnson's first time on the track. She was the only driver on the track when the crash occurred and was unconscious when worked pulled her from the vehicle.

Witnesses told the Ocala Star-Banner that Johnson was making a second lap when she apparently lost control of the vehicle and crashed into a concrete barrier.

The sheriff's office is looking into the crash as an accidental death investigation.
