A Wisconsin judge has set a July 15 sentencing date for Aaron Schaffhausen, the man who pleaded guilty to killing his three daughters in the girls' River Falls home.

A jury found last week that Schaffhausen, 35, was legally sane when he killed 11-year-old Amara, 8-year-old Sophie and 5-year-old Cecilia on July 10. Although the 12-member jury unanimously agreed that Schaffhausen suffered from a mental disease or defect at the time, they found that it did not prevent him from knowing what he did was wrong or from controlling his actions.

That means Schaffhausen will be sentenced to prison instead of a mental institution at the sentencing hearing before St. Croix County Circuit Court Judge Howard Cameron.

Schaffhausen faces a mandatory sentence of life in prison for each daughter's death. The judge could decide to make him eligible for extended supervision after he serves at least 20 years, but could also decide he will get no chance at release.
