Marcel Petiot was a French doctor who was suspected of killing over 60 people. Petiot served in World War I, but was discharged after he injured his own foot with a grenade. After the war, Petiot turned to medicine, and completed an accelerated medical program designed for war veterans. He moved to Villeneuve-sur-Yonne, a commune in Northern France. Petiot quickly gained a reputation of dubious practices after performing illegal abortions and supplying patients with narcotics, which he was also suspected to be abusing himself. Despite this, Petiot became mayor of Yonne, but was soon accused of theft.
