Serial Killer Marcel Petiot Helped the Allies & Secretly Murdered Dozens
Marcel Petiot (full name Marcel André Henri Félix Petiot) was a Parisian doctor, spy, and a serial killer responsible for as many as 60 deaths. He was recruited by a U.S. spy agency known as the Pond. Petiot, a former mental patient, gathered intel about German military operations but also used his office for nefarious purposes. He tricked patients by telling them he’d help them travel to Argentina and gave them a “vaccine” for the trip that was cyanide. In 1943, the Gestapo suspected Petiot created a real escape route and arrested him. Less than a year later, Paris police found the remains of dozens of victims in his apartment basement. Following the war, he was tried and sentenced to death by guillotine.
