The horrifying car crash that killed Jackass star Ryan Dunn was inevitable as the alcohol level in his blood was twice the legal limit, according to Pennsylvania state police.

When Dunn crashed his Porsche 911 GT3 into a patch of trees at over 130mph on early morning Monday, he had a blood alcohol of 0.196 percent or more than twice the state's legal limit (0.08), the police said.

No other substances were found in his blood other than the alcohol, West Goshen Police Chief Michael Carroll said. Speed may have been a contributing factor to the accident, police said.

The crash killed Dunn and his friend (and former Navy SEAL) Zach Hartwell died instantly in the car crash. Before their death, Dunn, Hartwell and some other members of the Jackass crew, were drinking heavily at a suburban Philadelphia bar Barnaby's in the wee hours before the crash.

Autopsy report said both Dunn and Hartwell died of blunt and thermal trauma. The accident took place approximately at 2:38 a.m. on Route 322 in the area of Pottsdown Pike.

The police also said Dunn had a prior DUI conviction. He also had 23 driving citations before his death. Among them were citations for speeding and careless driving, driving an unregistered vehicle, driving without a license, two parking-related transgressions and a criminal mischief-damage to property citation.

Barnaby's manager said Dunn didn't look drunk on the night of the crash. The manager, who refused to give his name, said the bar is cooperating with the police.

Jackass costar Bam Margera's mother April, who loved Dunn as her own son, was shocked by the news and told NBC 10 that she always warned Dunn not to overspeed and drive dangerously.

He (always) drove too fast and I yelled at him all the time about that, April said.
