HUDSON, Wis. – Prosecutors may send two mental health experts to assess a man accused of killing his three daughters in the girls' River Falls home last summer, a judge ruled Wednesday.

Aaron Schaffhausen entered an insanity plea in the case last month, and prosecutors last week asked for a hearing to clarify rules surrounding mental health interviews from the state's hired experts.

Defense attorney John Kucinski agreed Wednesday that he wouldn't be present during the interviews, but he argued Schaffhausen shouldn't be subjected to more than one by prosecutors' experts.

Judge Howard Cameron said Wisconsin state law sets no limits.

Prosecutor Gary Freyberg, arguing by speaker phone from Madison, said the state would send two experts separately.

Schaffhausen, 35, is facing three counts of first-degree intentional homicide in a trial scheduled to begin April 1.
