So many of Jackass star Ryann Dunn's friends and fans have expressed deep regret at his passing.

Finally, they know the cause of Dunn's untimely demise.

The culprit?

A lethal combination of intoxicated driving and speeding

Police reports have revealed that Dunn, who died in a car accident in Pennsylvania Monday night had twice the legal limit of alcohol in his blood-system, according to the Associated Press.

Pennsylvania's legal state blood-alcohol level is .08, and Dunn's was .196 at the time of his death.

Police reported that Dunn's vehicle was also travelling well over 100mph in a 55 zone when he died.

There is an uproar over cineaste Roger Ebert's tweet in response to the event:

Some 19 hours ago, @ebertchicago (Roger Ebert) tweeted:

Friends don't let jackasses drink and drive.

Ryan Dunn's fans have lashed out against Ebert in response to what they believe was an insensitive, untimely comment that didn't value Ryan Dunn's life and the loss thereof.

Mothers Against Drunk Driving (MADD) has yet to issue a statement on Dunn's death, analysts say because of the backlash against Ebert for speaking up too soon after the tragedy.
