BMX star Dave Mirra, once the winningest athlete in X Games history, has reportedly died by suicide. He was 41. 

Mirra was found dead by a self-inflicted gunshot wound in his truck, say police in Greenville, North Carolina, where he had reportedly been visiting friends. He is survived by his wife and two children. 

As a dominating and influential BMX competitor, Mirra inspired countless riders. After winning 24 X-Games medals (including a then-record 14 gold) and landing the first-ever double backflip in the Games' history, Mirra raced rally cars, competed in triathlons, and even won the grueling five-day Race Across America alongside former Tour de France racer Dave Zabriskie and motorcycle racing legends Micky Dymond and Ben Bostrom. 

"I just wish he would have called me," T.J. Lavin, BMX athlete and Mirra's close friend, told TMZ. "I would have jumped on a plane in a second. There's always another way. If anyone needs help, just please get it. I feel sick about this."
