Ryan Dunn (Far Left) Zachary Hartwell (Far Right)

Jackass star Ryan Dunn died early Monday morning in Pennsylvania when his Porsche flipped, crashed and burned. Police initially withheld the identity of his passenger, but have since revealed that it was Zachary Hartwell of West Chester, Pennsylvania.

According to local Pennsylvania news reports, the car careened off the road, flipped over a guardrail and crashed into the woods before bursting into flames. The force of the 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. The bodies were severely burned. Police were able to identify Dunn through his tattoos and hair. Crash Photos.

Hartwell, 30, was a production assistant for Jackass 2 and a stunt car driver in Bam Margera‘s 2009 film, Minghags. He was a former Navy Gunner’s Mate who served two tours of duty in Iraq. He married his wife Rachel in October 2010.

Margera became enraged after movie critic Roger Ebert played the blame game with a few controversial Twitter missives.
