RAPID CITY, S.D. — A flat-track motorcycle racer from Black River Falls died last week from injuries he sustained during a crash Aug. 7 at Black Hills Speedway in Rapid City, according to a release from the American Motorcyclist Association American Flat Track series.

Alec Muth, 22, "succumbed to his injuries" on Thursday despite "the immediate action of first responders and the best efforts of the very experienced staff at Rapid City Regional Hospital," according to the release.

Muth was a member of the Black River Falls Fire Department. The department wrote a tribute to Muth on its Facebook page, saying he loved motorcycle racing "just about more than firefighting."

The Harley-Davidson Black Hills Half-Mile was held the night of Muth's accident at the Black Hills Speedway in conjunction with the Sturgis Motorcycle Rally.
