The parents of a man who has admitted killing his three young daughters testified about their son's troubled childhood and mental health issues as the second week of his sanity trial got underway in western Wisconsin.
Roger Schaffhausen testified his son, Aaron Schaffhausen, was a rebellious and belligerent teen who had some "run-ins with the law." The elder Schaffhausen says his son stole a gun, brought it to high school and was expelled.
KARE-TV reports Sue Schaffhausen testified Monday that her son became extremely depressed when he and his wife, Jessica, broke up. She also testified that mental illness was an issue for other members of her family.
Schaffhausen has pleaded guilty to killing 11-year-old Amara, 8-year-old Sophie and 5-year-old Cecilia at their house in River Falls last July.
