HUDSON, Wis. - A jury on Tuesday rejected an insanity defense by a Wisconsin father who admitted to killing his three young daughters last July, finding he had a mental defect but still understood he was doing something wrong when he slashed his girls' throats, then tucked their bodies into bed.
Aaron Schaffhausen, 35, faces a maximum penalty of life in prison with no parole when he is sentenced. The St. Croix County Circuit Court jury deliberated for about 3 1/2 hours before reaching its unanimous verdict.
Schaffhausen pleaded guilty earlier to three counts of first-degree intentional homicide and one count of attempted arson. But he maintained he wasn't responsible for killing 11-year-old Amara, 8-year-old Sophie and 5-year-old Cecilia because of a mental illness.
The jury was tasked with weighing Schaffhausen's sanity. Prosecutor Gary Freyberg said jurors found "the truth of the case."
"He was guilty. He was sane. And the jury got it right," Freyberg said. He called the killings a "brutal, brutal series of crimes" and added: "He understood what he was doing. He said he was going to do this, and he went out and did it."
Flint Watt, an uncle of Schaffhausen's ex-wife Jessica, said the family views the verdict as one step in a long recovery.
"Aaron's going to be spending a long time, I think, thinking about what he's done," Watt said. Some of Jessica's family members sighed and quietly cried as the verdict was read.
Defense attorney John Kucinski said he would appeal. He said Judge Howard Cameron instructed the jury on motive when it wasn't relevant. He also said the judge shouldn't have denied the jury's request to have expert reports in the room as they deliberated.
