11. Erna Petri
At first, Erna Petri seemed totally harmless. She was coming home from work when she spotted six children, all Jewish, alone at the side of the road. The children had escaped from a train heading towards Sobibor extermination camp and Petri offered them shelter and food. But little did they know that she was married to an SS officer.
Once at home, Petri fixed the children a hearty meal. After they had gotten settled, Petri rounded the children up and led them to a desolate spot in the woods. She shot and executed all six children at point-blank range. After the war, Petri was convicted of murder and sentenced to life in prison by the East German government. Her husband was sentenced to death.
