(Hudson, WI) – The three daughters allegedly killed by their father in River Falls, Wisconsin, died from having their throats slashed. Homicide charges were filed Thursday against the girls’ father, 34-year-old Aaron Schaffhausen, in what prosecutors call the worse case they’ve ever seen. The victims: five-year-old Cecilia, eight-year-old Sophie and 11-year-old Amara were found dead Tuesday, tucked into their beds, blankets up to their necks. Schaffhausen and his wife had recently divorced and police say the girls happily rushed to the door when Schaffhausen showed up for a suprise visit. He later called his wife and told her she could go home now because he had killed their daughters.
