'Jackass' Star Ryan Dunn Autopsy Released

Police estimate Dunn's car was going 130 mph when he crashed.

The initial autopsy of "Jackass" star Ryan Dunn and the passenger killed in an early-morning wreck in rural Pennsylvania on Monday revealed that the two died from blunt-force trauma and the fire that consumed Dunn's vehicle.

According to the Chester County Coroner, Dunn and 30-year-old Zachary Hartwell were both dead before police arrived at the scene of the accident, which occurred around 2:30 a.m. on Monday in West Goshen Township, when the amateur daredevil's 2007 Porsche 911 GT3 swerved off the road and flew through 40 yards of trees before hitting one and bursting into flames.

West Goshen Police Chief Michael Carroll told Radar Online that an accident-reconstruction team was able to determine that the Porsche was traveling at a very high rate of speed — almost 130 mph — when it collided with a guardrail.

"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 was by far the worst I've ever seen."

TMZ reported that, based on the autopsy results, "It seems it was impossible to determine if the two died from the impact of the crash itself or from the fire that resulted."

The coroner also told the site that toxicology results for both men — which would help determine whether alcohol was involved in the crash — would be released in four to six weeks. In the hours before the crash, Dunn was photographed drinking at Barnaby's of America, a bar in West Chester, Pennsylvania, leading some to speculate that he was drunk before the accident occurred. But an employee of the bar told MTV News that he "didn't seem intoxicated."

"He seemed like he was having a good time, hanging out with friends," the employee said. "[He] only had a couple beers here. As far as we're concerned, the biggest thing, our hearts go out to the family and friends, and his loss is a big loss to our community. The biggest thing we're worried about is his friends and family."
