Ep 51 - Karen Greenlee, and Terrible Twins

Summary: A necrophile is a person who is sexually attracted to corpses. Nine out of ten necrophiles are men. It is extremely rare for a woman to indulge in necrophilia: Karen Greenlee was one of them. She was caught after stealing a body on its way to a funeral in 1979. What happens if one identical twin commits a horrible crime, but points the finger at the other? How do police know they have got the right or wrong man?
