Jackass star Vincent "Don Vito" Margera has died at age 59. Vincent, the uncle of Bam Margera, passed away early Sunday morning, TMZ reported. Bam's mother confirmed the news to TMZ. Vincent reportedly died after he had slipped into a coma last month from the effects of kidney and liver failure over the course of a few years. His condition had been worsening in recent weeks. Vincent appeared on MTV's Jackass -- and the Jackass movies that were released in theaters later on -- as well as Viva La Bam, a TV series which debuted in 2003 and concluded in 2006. The Jackass family just recently lost Ryan Dunn in June 2011 from a tragic car crash in Pennsylvania when he was turning 38.
