Insanity defense: Six notorious cases when it worked
And also by killing people.
Gein ultimately confessed to murdering two women -- Mary Hogan in 1954 and Bernice Worden in 1957. After Worden's body was found strung up as if she was a deer, Gein was arrested, but he was subsequently found to be criminally insane and locked up in a mental health facility.
Eleven years later, authorities tried again, putting Gein on trial for Worden's murder. He was found guilty, but he was ordered to spend his life sentence at a mental hospital. He died in 1984, but his horrifying influence continues to linger to this day.
