Jeret "Speedy" Peterson, the freestyle skier who won a silver medal at the 2010 Vancouver Olympics, has died, The Salt Lake Tribune reports.

The 29-year-old shot himself in the head in a canyon east of Salt Lake City, officials told the newspaper. Peterson's body was discovered outside his car off of an interstate Monday evening after he left a suicide note and called the police to tell them his location, according to police.

"He called 911 and said he was going to kill himself," Lt. Justin Hoyal, a spokesman for the Unified Police Department, told The Salt Lake Tribune.

Peterson's death came just three days after he was arrested in Idaho on a DWI charge. It was well-known that Peterson battled depression, gambling and alcoholism. He was sent home from the 2006 Turin Olympic games because of a drunken street fight with a friend.

When he won the silver medal for aerials in 2010, it was seen as a victory over his past demons. In addition to that medal, Peterson had also won gold twice, in the 1999 U.S. Junior National Championships and in the 2006 U.S. National Championships. He had not planned on competing in next year's ski season and had been working toward a business degree at Westminster College.
