Ryan Dunn doing 130mph at time of fatal crash?

Ryan Dunn was reportedly speeding before his fatal car accident on Monday.

The 34-year-old Jackass star, who died when his Porsche crashed at 3am local time at Route 322 and New Street in West Goshen Township, was allegedly travelling at 130mph just beforehand.

An accident reconstruction team has determined the speed of the crash after inspecting the scene of the incident, according to TMZ.

Officials have also claimed that Dunn's car collided with a rail, crashed into the woods and then burst into flames.

A police eyewitness told the publication that the accident was the "worst" he has ever seen, adding that he has "never seen a car destroyed in an automobile accident the way this car was, even before it caught on fire".

Since the tragedy, Dunn's Jackass co-stars have taken to Twitter to express their grief. Johnny Knoxville referred to him as his "brother", while Steve-O said that he will "really miss him".

The passenger who also died in Dunn's car accident has since been named as his 30-year-old friend Zachary Hartwell.
