The father accused of killing his three daughters in their River Falls, Wis. home entered an insanity plea on Wednesday, according to officials.
Aaron Schaffhausen previously had a Dec. 14 deadline, set by St. Croix County circuit court Judge Howard Cameron, but failed to enter a not guilty plea by reason of insanity at that time. Kuscinski told the River Falls Journal he hadn’t received all the evidence to make a decision in December.
