Police investigation: Mechanical failure led to Jason Leffler crash, death

Jun 21, 2013, 11:26 PM EDT

This was the car Jason Leffler was driving when it suffered mechanical failure, according to a report issued Friday by the New Jersey state police. Reuters

Following more than a week-long investigation, New Jersey state police said the wreck that claimed the life of NASCAR driver Jason Leffler in a June 12 dirt track race in Bridgeport, N.J., was caused by a mechanical problem.

While the report is not fully completed, several findings have come to light to explain much of the reason why Leffler’s car suddenly went out of control and flipped several times before coming to rest. Leffler was taken to a nearby hospital but was pronounced dead less than an hour after the wreck, which occurred shortly after 9 pm ET.

Police believe a torsion stop, which is part of the sprint car’s suspension, somehow broke off and became lodged between a wheel and the steering control system, rendering the car uncontrollable. The car came out of the fourth turn, spun, then hit the outside concrete retaining wall, flipping several times before coming to a rest, as well.

While the report has not determined how fast Leffler was going when the crash occurred, the police report said cars were averaging 135 mph and as high as 150 mph on both straightaways during the course of the race.

The official cause of death, as determined by a local medical examiner, has been ruled blunt-force injuries to Leffler’s neck.

Leffler, 37, was buried Wednesday, one week after the tragedy. He leaves behind a five-year-old son. A trust fund for Leffler’s son has been established by several of Leffler’s fellow NASCAR drivers.

Longtime friend and mentor Tony Stewart, a three-time Sprint Cup champion who also co-owns Stewart-Haas Racing and owns or has partial ownership in several short tracks like the New Jersey facility, said last week in Michigan that the facility was not at fault.

“It was an accident,” Stewart said. “Just like if you go out and there’s a car crash. It’s an accident. Nobody as a track owner wants to go through what happened this week, but it’s not due to a lack of effort on their part to try to make their facilities as safe as possible under the conditions they have.”
