U.S. bobsledder Steven Holcomb, who came back from a suicide attempt over impending blindness to win Olympic gold in 2010, was found dead at a training site on Saturday, the U.S. Olympic Committee said, Reuters reported.
Holcomb, 37, was discovered in his room at the U.S. Olympic Training Center in Lake Placid, New York, the committee said in a statement. It gave no further details.
Holcomb, who underwent successful surgery in 2008 to overcome a degenerative eye disease, made history at the Vancouver Olympics when he piloted the U.S. four-man bobsled team, nicknamed "Night Train," to the gold medal.
It marked the first U.S. gold medal in the event since 1948 and the three-time Olympian's comeback from depression over increasing blindness, according to his biography on the Team USA website.
Holcomb took bronze medals in both two-man and four-man bobsled at the 2014 Sochi Games. He also won five world titles among his 10 world championship medals and was a six-time overall world cup champion, winning 60 world cup medals.
The New York State Police, which is handling the case, had no immediate comment on Holcomb's death.
"The entire Olympic family is shocked and saddened by the incredibly tragic loss today of Steven Holcomb,” U.S. Olympic Committee Chief Executive Scott Blackmun said in a statement.
