RIVER FALLS, Wis. — A run and walk in the western Wisconsin community of River Falls has raised nearly $50,000 for a proposed playground dedicated to the memory of three girls who were slain by their father.

The Tri Angels 5K at Hoffman Park on Saturday honored the three Schaffhausen sisters— 11-year-old Amara, 8-year-old Sophie, and 5-year-old Cecilia. Organizers say it drew 1,250 participants.

Jessica Schaffhausen says summers spent at Hoffman Park are among her favorite memories of her daughters. She says they would walk from their home past the park to the library and home again.

Prosecutors say the girls' father, Aaron Schaffhausen, killed them last year in an act of revenge against his ex-wife. He tried to claim insanity. He was sentenced Monday to life in prison with no chance of parole.
