HUDSON, Wis. (AP) — A jury on Tuesday rejected an insanity defense by a Wisconsin father who admitted killing his three young daughters last July, ruling that the man had a mental defect but still understood what he was doing was wrong.
Aaron Schaffhausen, 35, had earlier pleaded guilty in St. Croix County Circuit Court to three counts of first-degree intentional homicide and one count of attempted arson. But he had maintained he was not responsible for killing 11-year-old Amara, 8-year-old Sophie, and 5-year-old Cecilia because of a mental illness.
Jurors deliberated for about 3½ hours before reaching their verdict.
Evidence in the case showed Schaffhausen texted his ex-wife Jessica on July 10 to ask for an unscheduled visit with the girls. She consented but said he had to be gone before she got home because she didn't want to see him. The girls' baby sitter told investigators the children were excited when he arrived. The baby sitter left. He called his wife about two hours later, saying: "You can come home now, I killed the kids."
Police arrived to find the girls lying in their beds, their throats slit and their blankets pulled up to their necks. White T-shirts were tied around their necks. Prosecutors said Aaron did that to keep their blood off his own clothes as he put them in bed. Cecilia also showed signs of strangulation.
In his closing argument Tuesday, prosecutor Gary Freyberg told jurors that Schaffhausen was a manipulator who knew what he was doing and wanted to punish his ex-wife in the worst way imaginable.
"These children did not have to die. They died because their father made a choice," Freyberg said. "He chose to kill them and betray everything that a parent stands for because he was jealous and angry."
Defense attorney John Kucinski countered to jurors that Schaffhausen has a rare mental disorder, rooted in a deep dependency on his wife. Kucinski said the only way Schaffhausen believed he could "solve" that problem was to commit suicide or homicide.
He cited a defense expert who testified the crime was a case of "catathymic homicide," evident by months of unwanted fantasies or desire to kill his girls, followed by a violent act — then a feeling of relief.
"There is nobody involved in this case that deserves an iota of blame because they could not know how ill his mind is," Kucinski said. "None of this is anybody's fault ... you just look at the guy and he doesn't look as sick as he is."
Trial testimony showed that in the months leading up to the killings, Schaffhausen told several people he had thoughts of killing his girls. His ex-wife, Jessica, testified that in March 2012, he called her from Minot, N.D., where he was working, and told her he "wanted to drive down there and tie me up and make me pick which child he killed and make me watch while he killed them."
He also called Jessica repeatedly, sometimes up to 30 times a day, and threatened to kill the man she was dating.
One of his co-workers, Jeremy Michels, wrote in an email to police after the killings that Schaffhausen had said things like: "I want to go kill my kids, then my ex-wife. After her, I will go to the man's house she is sleeping with, kill him, cut his head off, put it on a stake in my front yard and then I will sit back and have a beer."
Michels testified that Shaffhausen also talked about killing his family and when Michels said that was crazy, Schaffhausen responded, "Is it really?" Schaffhausen also once told him, "I'll pay you to kill her," Michaels testified.
Schaffhausen declined to testify at the trial. But the defense played a recording of his interview with police in the hours after the slayings.
During the first two hours of the video, he is silent. In the final hour, he broke down crying as an investigator asked him about tucking the girls into their beds. Later, he is seen on the videotape saying, "I don't know what I want; I don't know what I need. I want my girls back; I want a lot of things. Can you give them to me? Then quit offering the world like you have the keys." He later said, "I need help."
Under Wisconsin law, to reach a verdict of insanity, only 10 of 12 jurors had to find evidence showing Schaffhausen suffered from a "mental disease or defect" that led him to lack the capacity either to appreciate the wrongfulness of his conduct or conform his conduct to the requirements of law.
