'Jackass' star Ryan Dunn died early Monday in a Pennsylvania car crash, police confirmed. April Margera, the mother of a fellow 'Jackass' dare devil, Bam Margera, told a local radio station and later TMZ that Dunn was killed in the car wreck that also left one other, who has yet to be identified, dead. He was 34.

"Today I lost my brother Ryan Dunn," said 'Jackass' boss Johnny Knoxville in a statement. "My heart goes out to his family and his beloved Angie. RIP Ryan , I love you buddy."
