Prosecutors anticipate a North Dakota man accused of killing his three daughters will plead not guilty by reason of mental disease or defect.
Aaron Schaffhausen faces three counts of first-degree intentional homicide and one count of attempted arson in the deaths of his daughters, 11-year-old Amara, 8-year-old Sophie and 5-year-old Cecilia. Police found the girls dead in their River Falls home last month.
Assistant Attorney General Gary Freyberg wrote in court filings that he believes Schaffhausen will enter a not guilty plea by reason of mental disease or defect when he's arraigned next week.
Schaffhausen's attorney, John Kucinski, told the Eau Claire Leader-Telegram newspaper several weeks ago that he plans to show Schaffhausen was delusional and depressed before the slayings. He declined to comment when reached by telephone Thursday.
