RIVER FALLS, Wis. (AP) – The western Wisconsin house where a father killed his three daughters last year will be dismantled.  Instead of being demolished, the River Falls house will be taken apart piece by piece, starting Monday. Salvageable items will be donated to Habitat For Humanity.  The Leader-Telegram reports the property eventually will be bulldozed and sold. Proceeds will be donated to a playground in honor of the slain girls.  Affinity Plus Federal Credit Union of St. Paul, Minn., held the note on the home. Dave Larson of Affinity Plus tells KARE-TV the decision was made after discussions with Jessica Schaffhausen, the girls’ mother.  Prosecutors say Aaron Schaffhausen killed the girls in an act of revenge against his ex-wife. He claimed he was insane but was sentenced to life in prison without parole.
