Race car driver Jason Leffler died from a blunt force neck injury, an autopsy revealed Thursday.
The Delaware County (Pa.) Medical Examiner ruled Leffler’s cause of death was the neck injury he sustained when his car impacted the wall at Bridgeport Speedway in New Jersey during a Wednesday night sprint car race.
New Jersey State Police are still investigating the cause of Leffler’s accident at the .625-mile dirt oval.
Leffler, a versatile driver who won championships in open-wheel divisions and attempted at least one full season in each of NASCAR’s three national series, had to be extricated from the car after striking a wall, New Jersey State Police Sgt. Adam Grossman said.
Leffler made 73 starts in the Sprint Cup Series, finishing last in his final event after completing eight laps Sunday at Pocono Raceway. He won twice in the Nationwide Series and once in the Camping World Truck Series.
The Long Beach, Calif., native was affectionately known as “LEFturn” and had the nickname stenciled above his driver’s side window.
