A jury said the Wisconsin father accused of killing his three daughters had a mental illness or defect when he committed the crime. However, the jury believes Aaron Schaffhausen knew what he was doing and therefore has rejected his insanity plea.
The final witness in the Aaron Schaffhausen sanity trial, a prosecution psychiatrist, took the stand Monday, testifying that Schaffhausen was sane when he committed the murders.
In the first hours of jury selection in Aaron Schaffhausen’s insanity trial, a prospective juror raised her hand and said she could not be impartial. She said she believed Aaron Schaffhausen had to be insane because of the crime he had committed; stabbing to death his daughters ages 11, 8 and 5.
