Philadelphia - Jackass daredevil Ryan Dunn and his passenger died from the impact of the violent car crash and the resulting fire, according to an autopsy report on Tuesday.
The Chester County coroner listed blunt force trauma and thermal trauma as the official causes of death for both men. Toxicology results will take four to six weeks to complete, coroner's office spokesperson Patty Emmons said.
Dunn was known for making viewers cringe and snicker through vulgar stunts with his cohorts in the multimillion-dollar Jackass TV and movie franchise.
Burst into flames
The 34-year-old Dunn and passenger Zachary Hartwell died early on Monday, shortly after leaving a pub in West Chester where Dunn had tweeted a photo of the pair and a third man drinking just hours before the crash. The photo has since been taken down.
A preliminary examination of the crash site suggested that Dunn's Porsche might have been traveling more than 160 km/h in the 89 km/h zone when it jumped a guardrail, flew into a wooded ravine, struck a tree and burst into flames.
The 30-year-old Hartwell was credited as a production assistant for the second Jackass movie.
'Devastated'
Dunn's brother, Eric Dunn, said in an emailed statement to the AP that his family was "devastated".
Mourners placed flowers and took photos at the accident scene in West Chester, while Facebook and Twitter were buzzing on Tuesday with condolences from fans around the world and friends from Hollywood to Chester County.
Among those expressing their sorrow online were Good Charlotte guitarist Benji Madden, reality TV star Brody Jenner and Dunn's Jackass movie and TV cohorts Bam Margera, Stephen "Steve-O" Glover and Jason "Wee Man" Acuna.
