HUDSON, WI (WSAU) - A psychiatrist says the man who killed his three daughters was mentally aware of his actions.
The sanity trial of Aaron Schaffhausen began it’s third week Monday. Prosecution witness Dr. Erik Knudson testified Monday that after Schaffhausen killed the girls, he drove around aimlessly while getting rid of items that could connect him to the crimes. Knudson says Schaffhausen's action shows he was "capable of conforming his conduct."
Aaron Schaffhausen pleaded guilty to murdering 11-year-old Amara, 8-year-old Sophie, and 5-year-old Cecilia Schaffhausen last year, but claims he’s not responsible because of a mental illness. Jurors will determine his sanity.
In the sanity trial, the defense has the burden of proof to show Schaffhausen was insane and it does not require a unanimous jury. Ten of the twelve jurors have to find him insane.
