RIVER FALLS, WI (WTAQ) - Over $30,000 were donated on the first day that a bank in River Falls opened a memorial fund for the three young sisters murdered this week. The Minneapolis Star-Tribune said children emptied their piggy banks, seniors gave $20 bills, and others wrote checks. Bank president Jeff Johnson expects more donations Friday and tomorrow – which are normally his bank’s busiest days. Johnson says he’s not surprised by all the outpouring of support for the Schaffhausen family. He said River Falls is a close-knit community, and people look out for each other when things go wrong. Cecilia, Sophie, Amara Schaffhausen had their throats slit on Tuesday at their mother’s home in River Falls. Their father, 34-year-old Aaron Schaffhausen of Minot North Dakota, allegedly killed the girls after his ex-wife Jessica allowed him to have a private visit with them. He’s in jail under a two-million dollar bond. Besides the bank fund, a restaurant in Hudson raised another 30-thousand for the family – and collection jars are abundant there. Jessica said she appreciated all the support – and when the time is right, the family will use the donations to honor the youngsters in the best way possible. She said the family approved the bank’s memorial fund and the selling of bracelets by Amara’s former soccer team. But the Schaffhausens are discouraging other memorabilia and T-shirt sales or fund-raising Web sites.
