'Jackass' star Ryan Dunn dies in car crash

"Jackass" star Ryan Dunn, who along with his cast mates made Americans cringe and snicker through vulgar stunts in their multimillion-dollar TV and movie franchise, was killed early Monday in a fiery car crash. He was 34.

Dunn, a daredevil who gained notoriety for diving into a sewage tank and performing other unsavory stunts, was driving his 2007 Porsche in suburban Philadelphia when it careered off the road, flipped over a guardrail and crashed into the woods before bursting into flames. A passenger was also killed, and speed may have been a factor in the crash, West Goshen Township police said. The force of impact shattered the vehicle into several twisted and blackened pieces, leaving the Porsche 911 GT3 unrecognizable except for a door that was thrown from the crash and not incinerated. A 100-foot-long tire skid marked where the car left the roadway.

Both Dunn and his passenger were severely burned. Police said they were able to identify Dunn through his tattoos and hair, but the identity of his passenger was still unknown. Dunn appeared on MTV shows "Jackass" and "Viva La Bam" and the three "Jackass" big-screen adaptations. He also was the star of his own MTV show, "Homewrecker," and just began hosting the show "Proving Ground" on the G4 cable network. AP
