Dunn and a passenger in his 2007 Porsche died after the car left
the roadway and burst into flames, West
Goshen Township
police said. The crash occurred near the Philadelphia
suburb of West Chester.
The 34-year-old Dunn appeared on MTV shows "Jackass"
and "Viva La Bam" and the three "Jackass" big-screen
adaptations. He also was the star of his own MTV show, "Homewrecker,"
and hosted "Proving Ground" on the G4 cable network.
According to a biography posted on his website, Dunn was born in
Ohio and moved at age 15 to Pennsylvania, where he met Bam Margera on
his first day of high school.
Dunn, Margera, Christopher Raab (known as Raab Himself) and
Brandon DiCamillo, under the moniker CKY for "Camp Kill Yourself,"
started making videos that featured them skateboarding and performing stunts.
Dunn was working as a welder and at a gas station when Johnny
Knoxville, a friend of Margera's through the skateboarding circuit, asked the
crew to allow their videos to be part of the series "Jackass," which
became a hit on MTV and ran from 2000 to 2002.
A phone message left for Dunn's manager wasn't immediately
returned.
The passenger who died in the crash had not yet been
identified, police said.
