Dunn was killed along with another passenger when the Porsche GT3 he was driving crashed in suburban Philadelphia at 3am on Monday morning, with police claiming that speed could have been in factor in the accident.
Dunn's fellow Jackass star, Johnny Knoxville, took to Twitter to express his sadness over the 34-year old's death, stating: "Today I lost my brother, Ryan Dunn. My heart goes out to his family and his beloved Angie. RIP Ryan. I love you buddy."

Jason 'Wee-Man' Acuna then added on the social networking site: "I miss you, bud. You were always a happy kick-ass dude!"
David England, who also starred in Jackass, tweeted: "I love you Ryan. I'm gonna miss you bad."
Speaking of Ryan's death, Van Toffler, president of MTV Networks Music/Film Group, stated: "We are devastated by the tragic loss of Ryan Dunn — a beloved member of the MTV family for more than a decade,"


This has been strongly denied by his friends and bar staff, with one onlooker telling our US Team that Dunn "wasn't too drunk to drive."
An employee of the establishment where Dunn was drinking also added that Ryan: “didn’t seem intoxicated. He was himself. He seemed like he was having a good time, hanging out with his friends.”
