The autopsy results for NASCAR driver Jason Leffler show that a blunt force neck injury is what killed him in that horrific sprint car crash in New Jersey last night.
Leffler's car flipped and impacted the wall at Bridgeport Speedway last night. He was extricated from the car and transported to the hospital, but died from his injuries shortly after 9 PM yesterday evening.
An investigation is still ongoing as to the cause of the crash.
