According to TMZ, police estimate the car had been doing nearly 130mph before it careened off the road and into a wooded area in the early hours of Monday morning.
Both Dunn and his passenger, now identified as Zachary Hartwell were dead upon arrival at the scene.

Police Chief Michael Carroll said it was the ‘worst’ accident he’s come across and that he’s ‘never seen a car destroyed in an automobile accident the way this car was…even before it caught on fire.’
On whether alcohol played a part in the crash, the toxicology reports won’t be released for four to six weeks.
Meanwhile Robert Ebert who soon after the tragedy tweeted ‘Friends don’t let jackasses drink and drive’ has since said he ‘was probably too quick to tweet’ about the accident.

After coming under fire from Jackass star Bam Margera for it he apologised on his blog for his comment:
‘To begin with, I offer my sympathy to Ryan Dunn’s family and friends, and to those of Zachary Hartwell, who also died in the crash,’ he wrote. ‘I mean that sincerely. It is tragic to lose a loved one.
‘I also regret that my tweet about the event was considered cruel. It was not intended as cruel. It was intended as true.’
He continued: I have no way of knowing if Ryan Dunn was drunk at the time of his death.
‘I don’t know what happened in this case, and I was probably too quick to tweet. That was unseemly.’
However he did defend the sentiment of his argument: ‘I do know that nobody has any business driving on a public highway at 110 mph, as some estimated - or fast enough, anyway, to leave a highway and fly through 40 yards of trees before crashing.’
