Earlier on Ryan Dunn's twitter, there was a picture of his and some buddies drinking (so this must have been a drink'n'drive accident). I wouldn't be surprised if this was a joke because I feel like the Jackass crew would do something like this.
But if it is in fact true, REST IN PEACE RYAN!
i just found this on ew.com Link
crashed his porche in West Goshen. if its a joke then its going a bit too far.
RIP to Dunn.
Also shame that Ryan died, he was my favourite in Jackasses.
