Olympic snowboarding medallist Jeret Peterson has been found dead in Utah.
The 29-year-old was found with a single gunshot wound to his head close to Salt Lake City. A police spokesman said a suicide note had been found at the scene.
Peterson had been arrested on Friday for speeding and drink-driving.
The American won silver at the 2010 Vancouver Games after finishing ninth at the 2002 Salt Lake City Games and being sent home from the 2006 Turin Games for a drunken altercation with a teammate.
The CEO of the American ski team, Bill Marolt, said: "Today is a sad day in our sport. Jeret was a great champion who will be missed and remembered as a positive, innovative force on not only his sport of freestyle aerials, but on the entire US Freestyle Ski Team family and everyone he touched."
