LONGVIEW, Wash. (AP) -- A 21-year-old Special Olympics softball player from Longview has died after collapsing during a regional tournament in Olympia, Wash.

The Daily News of Longview reports that Charles T. Huff died of a heart attack.

Just minutes before he collapsed in the dugout at LBA Park Saturday, Huff had hit a single. His stepfather, Tyler Johnson, was on the field coaching when several people yelled there was a medical emergency.

Olympia Fire Department medics tried to revive Huff but were unsuccessful. He was pronounced dead at St. Peter's Hospital.

Huff, who was born with Down syndrome, graduated from high school this year. His softball team had won their first game of the day and was leading their second game when Huff collapsed. The rest of the game was called off.
