SALT LAKE CITY — A Utah judge has dismissed domestic violence and assault charges against Olympic gold-medal skier Picabo Street.

Street was facing misdemeanor charges after prosecutors say she threw her 76-year-old father down the stairs and locked him in the basement during a fight at her home near Park City. Her lawyer says the 44-year-old Street was defending herself during the Dec. 23 incident.

Prosecutors last week moved to drop the charges, saying the matter shouldn’t be handled in court but instead reviewed by a state office that investigates elder abuse.

A judge closed the case Monday.

Prosecutors did not return messages seeking comment but Street’s lawyer Joe Wrona says statements from the skier’s mother and father made it clear she was acting in self-defense.

Street won a gold medal at the 1998 Winter Olympics in the women’s super-G.
