Police in River Falls, Wis., asked for the public's help Friday in finding a laptop computer that might belong to Aaron Schaffhausen, the man charged with killing his three daughters on Tuesday.
The laptop and case may have been abandoned on the side of the road or in a ditch between the family's house and Baldwin, Wis., police said. The laptop is a Sony VAIO in a Targus laptop bag.
Police believe Schaffhausen, 34, might have disposed of the laptop before he turned himself in to police about 4:45 p.m. Tuesday. He might have driven on roads east or north of the family's home in the 2700 block of Morningside Avenue in River Falls in a blue 2012 Chevrolet Cruze with California license plates, the news release said.
Authorities did not say what might be on the laptop, how they know about it and why Schaffhausen was driving a car with California plates.
Anyone finding it is asked to call the police at 715-425-0909.
Schaffhausen was charged Thursday in St. Croix County District Court with three counts of first-degree intentional homicide in the deaths of his daughters, Amara, 11; Sophie, 8, and Cecilia, 5. The two oldest girls' throats were slit. Cecilia was strangled and her throat was slit also.
According to charges, Schaffhausen unexpectedly texted and called his ex-wife, Jessica Schaffhausen, Tuesday asking if he could visit their children, who lived with her. The couple had divorced in January; he was living in Minot, N.D.
She granted him permission, and he arrived at the home about 1:30 p.m. A baby sitter left after consulting with Jessica Schaffhausen.
