Dave Mirra, BMX Pro and Host of MTV's Challenge, Dead of Apparent Suicide

Dave Mirra, an X Games champion who hosted two seasons of MTV’s Real World/Road Rules Challenge from 2001 to 2002, was found dead in his truck in Greenville, N.C., on Thursday.

The 41-year-old biker died of an apparently self-inflicted gunshot wound, according to TMZ Sports, though police are still looking into his death.

In addition to his work on MTV, Mirra was the subject of a series of video games, including Playstation’s Dave Mirra Freestyle BMX. He also made special appearances on Punk’d — in which Ashton Kutcher tricked him into thinking he was in trouble with the IRS — and The Late Show with David Letterman.

MTV mourned the loss of the former Challenge host on Twitter:

Mirra is survived by his wife, Lauren, and two children.
