Ogre of the Ardennes: Michel Fourniret
He's known worldwide as the "Ogre of the Ardennes." Frenchman Michel Fourniret's exploits terrorized Europe in the 1980s and '90s as he kidnapped, raped and murdered nine young women in a reign of terror across France and Belgium. When he attempted to kidnap his 10th victim, his wife refused to conceal his sickness any longer. She went to authorities. Fourniret was arrested, convicted and sentenced to life in prison where he remains today.
