The man accused of killing his three daughters in River Falls, Wis. last July isn't expected to enter a guilty plea until Thursday, WCCO reports.
Aaron Schaffhausen's plea was expected Wednesday at hearing in St. Croix County Circuit Cout, but was delayed.
According to his public defender, John Kucinski, Schaffhausen maintains he is not responsible for the crimes by reason of insanity.
The change of plea would allow the trial to consist of a single phase involving Schaffhausen’s state of mind. Otherwise there would be a criminal phase followed, if necessary, by an insanity phase.
Last month the judge ordered Schaffhausen to submit to multiple psychiatric evaluations.
Schaffhausen is charged with murdering his 11, 8 and 5-year-old daughters last summer in the River Falls home where they lived with his ex-wife.
