Marcel Petiot

French multiple homicide. He was arrested 31 October 1944 and convicted of the mass serial murders of 27 people, confessing to the murder of 67. During WW I while in the Army, 1917, he stole drugs and sold them to addicts. While practicing medicine at Villeneuve he became Mayor of the town. During WW II he killed 63 Jews, claiming that he would help them escape. He injected them with poison, a supposed immunization against foreign disease. He then put them in a windowless concrete room he had had constructed to order and watched them die through a peep-hole.

Stinking black smoke pouring from his chimney worried neighbors who alerted police and the fire department. They found bones of 27 corpses. Petiot convinced the authorities that the bodies were those of collaborators who had been executed by the Resistance. His local reputation was so good that he was believed until the war ended in August 1944. After the fall of Paris, the truth was discovered. After his arrest and trial, he was given the death sentence on 4 April 1946 and executed by guillotine on 25 May 1946, 5:07 AM Paris, France.
