Olympic track cyclist Catlin died of an apparent suicide on March 8, the Associated Press reported.
The 23-year-old athlete earned a silver medal with the women's pursuit team at the 2016 Rio De Janeiro Games.
Per the AP, Minnesota native Catlin was found dead in her California home.
Her father, Mark Catlin, told the competitive cycling magazine Velo News that the Olympian died by suicide.
"There isn't a minute that goes by that we don't think of her and think of the wonderful life she could have lived," he told the sports outlet. "There isn't a second in which we wouldn't freely give our lives in exchange for hers. The hurt is unbelievable."
