Ryan Dunn was going 130 mph in his Porsche at the time of the crash that killed the Jackass star and his passenger, according to the West Goshen police.

Police Chief Michael Carroll told reporters an accident reconstruction team determined the speed of the crash after inspecting the scene. Dunn's car collided with a guardrail at high speed, crashed in the woods and burst into flames.

The crash was so catastrophic it prompted Carroll to say it was the worst accident he had ever seen, saying he's never seen a car destroyed in an automobile accident the way this car was ... even before it caught on fire, TMZ reported.

Dunn, 34, and his passenger, Zachary Hartwell, 30, both of West Chester, Pennsylvania, died of blunt and thermal trauma in the pre-dawn hours on Monday, after a night of drinking with friends.

Both were pronounced dead on the scene by the Chester County Coroner's Office.

Toxicology test on their bodies are being conducted and will be released by the West Goshen Township Police Department upon receipt of the written report of the findings.
