Aaron Schaffhausen already faced murder charges for allegedly killing his three daughters in the River Falls, Wisconsin, home the girls shared with his ex-wife. The new arson charge is punishable by up to 20 years in prison. Authorities say Schaffhausen poured gasoline on the basement floor of the house.

Police are searching roadsides in western Wisconsin for a laptop computer that belonged to Aaron Schaffhausen, the man charged with murdering his three daughters in their River Falls home last week. Police believe Schaffhausen got rid of the computer after the girls were killed and before he turned himself in.

Her uncle says Jessica Schaffhausen is doing "amazingly well" since her three daughters were found dead in their home last week. The family asked news media to stay away from a memorial service for the girls in River Falls. Family members hope it helps bring some closure. The girls' father, Aaron Schaffhausen, is charged with three counts of first-degree murder.
