'Jackass' star Ryan Dunn and passenger Zachary Hartwell, were killed Monday in Pennsylvania after Dunn's Porsche went off the road, hit a guardrail and careened into the woods where it caught on fire.

According to the L.A. Times, the official coroner's report confirms that blunt force trauma and thermal trauma were the official causes of death in the accident.

After an accident reconstruction, Police Chief Michael Carroll told RadarOnline.com that the Porsche 911 was going "about 130 mph" when the accident happened in a reported 55-mph zone.

"I've never seen a car destroyed in an automobile accident the way this car was even before it caught on fire," Carroll said. "The automobile actually came apart. It was unbelievable and I've been on a lot of fatal accident scenes. This is by far the worse I've ever seen."

Although there has been heavy speculation as to whether the group's night of partying had a direct influence on the fatal crash, the tragedy has been labeled an 'auto accident' rather than a 'DUI,' pending the results of a toxicology report, which will be available in four to six weeks.
