Father Charged in 3 Daughters' Deaths in Wisconsin A North Dakota man was charged Thursday with three counts of first-degree intentional homicide in the deaths of his three young daughters in northwestern Wisconsin. Police discovered the bodies of 11-year-old Amara Schaffhausen, 8-year-old Sophie Schaffhausen and 5-year-old Cecilia Schaffhausen in the home they shared with their mother in River Falls on Tuesday. Authorities have not said how the girls were killed, but when police entered the home they noted the first-floor gas fireplace was on and the basement smelled of a flammable liquid they have yet to identify. Investigators said their father, 34-year-old Aaron Schaffhausen of Minot, unexpectedly contacted the girls' mother - his ex-wife - on Tuesday and asked for an unplanned visit with the children. The mother, who wasn't home, agreed and when Schaffhausen showed up at the house the girls' baby sitter left.

No one was home when police arrived at the house and discovered the bodies. Schaffhausen turned himself in late Tuesday afternoon and was being held at St. Croix County jail. His initial court appearance was set for Thursday afternoon. An announcement in The (Springfield, Ill.) Court records show they divorced in January. River Falls Police Chief Roger Leque has said records show what the chief called "an harassment incident" at the house in March 2012 in which the father threatened to harm at least one of the girls. But the chief said police were unaware of any restraining or protection orders. The house stands in a newer subdivision on the east side of River Falls, a city of 15,000 people about 30 miles east of the Twin Cities.
