The pro biker, who hosted MTV's The Challenge from 2004-05, posted to his Instagram twice the day he was found dead. (Both Instagrams seem to be screenshots of previous posts.) The first, a photo of what appears to be Mirra and his wife, was captioned: "My rock! Thank god."
"Considered an icon in the pro-BMX world, Mirra, was instrumental in bringing the sport to the City of Greenville, which now is home to more than 20 professional BMX riders," Greenville Police said.
"We mourn the loss today of a great friend and wonderful human being who touched the lives of so many around the world with his gift," said Greenville Mayor Allen Thomas. " He called Greenville, North Carolina home and was as humble a guy talking with kids on a street corner about bikes as he was in his element on the world stage. A young life with so much to offer was taken too soon."
The police department added that Mirra's family "would appreciate privacy during this very difficult time."
