RAPID CITY, S.D. (AP) — Authorities say they've that one of the participants in a mock Old West gun battle in South Dakota fired live ammunition instead of using blanks, wounding three tourists.

More than 100 people attended the show a week ago staged by the Dakota Wild Bunch re-enactors, who perform several times a week in Hill City, a tourist town in the Black Hills.

The ammunition shattered a 65-year-old Minnesota woman's fibula a bone in the lower leg. A 48-year-old Pennsylvania man and a 52-year-old Nebraska man were also wounded.

The Pennington County Sheriff Kevin Thom was to release a statement with more details later Friday.

There was no immediate comment from re-enactors. On their Facebook page, the group has said they are not allowed to bring live rounds to their performances.
