RIVER FALLS, Wis. - A Wisconsin man accused of killing his three daughters in River Falls, Wisconsin last July has entered an insanity plea in the case.
Aaron Schaffhausen entered a plea in St. Croix County Circuit on Wednesday of not guilty by reason of mental disease or defect to three counts of first degree intentional homicide and one count of attempted arson.
Schaffhausen is accused of killing 11-year-old Amara, 8-year-old Sophie and 5-year-old Cecilia. All three girls were found tucked into their beds with their throats slit.
Prosecutors also say Schaffhausen doused his home with gasoline and attempted to set it on fire.
