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, who was killed early on Monday in a fiery car crash was driving his 2007 Porsche in suburban Philadelphia when it careened off the road, flipped over a guardrail and crashed into the woods before bursting into flames.
The force of impact shattered the vehicle into several twisted and blackened pieces, leaving the Porsche 911 GT3 unrecognisable except for a door that was thrown from the crash and not incinerated. Both Dunn and Hartwell were severely burned. Police said they were able to identify Dunn through his tattoos and hair.
A passenger, Zachary Hartwell, 30, was also killed, and speed may have been a factor in the crash, police said.
A few hours before the 3am crash, Dunn tweeted a picture of himself drinking with two friends. The photo has since been removed. According to court documents, Dunn was charged in April 2005 with driving under the influence after crashing his car about 3.22 kilometres north of Monday's crash site.
Dunn was a daredevil who gained notoriety for diving into a sewage tank and performing other unsavoury stunts.
