Prosecutor: Dad was sane when he killed girls

Prosecutors say a Wisconsin man who has admitted he killed his three young daughters was in control of his actions and decided that a “selfish desire for revenge” was worth more than his girls’ lives.

Jurors are weighing whether Aaron Schaffhausen was legally sane when he killed 11-year-old Amara, 8-year-old Sophie and 5-year-old Cecilia in their River Falls home last July.

During closing arguments Tuesday, prosecutor Gary Freyberg told jurors that Schaffhausen was in control of his actions, and that he is a mean, callous person — but not legally insane.

Defense attorney John Kucinski said earlier that Schaffhausen has a rare mental disorder, rooted in a deep dependency on his wife.

Schaffhausen has pleaded guilty to three counts of first-degree intentional homicide, but he maintains he’s not responsible.
