Jean-Claude Romand (born 11 February 1954) is a French spree killer and impostor who pretended to be a medical doctor for 18 years before killing his wife, children and parents in January 1993 when he was about to be exposed.
Heavy suspicions also weigh around the death of his father-in-law, Pierre Crolet, who fell from a staircase on 23 October 1988. Jean-Claude Romand is the only witness to the alleged accident.
Marie-Louise Victorine Bessarabo (pen names, Héra Mirtel, Juliette de Boulogne, Juliette de Lotus; 24 October 1868 - 21 March 1931) was a French writer, woman of letters, militant feminist, salonnier, lecturer, and ardent suffragist. She was also a spiritist and a "believer in the Black Mass," a stock exchange gambler, a plotter for the restoration of the royalist regime in France, as well as an advisor of other women in matrimony and affairs of the heart. Mirtel was famous for the murder of her second husband, Georges Bessarabo, whose body was sent in a "bloody trunk" "from Paris to Nancy, by rail. Brilliantly defended by Vincent de Moro-Giafferi, she was sentenced to twenty years' imprisonment. She was suspected of having murdered her first husband as well.
Jeanne Weber (7 October 1874 – 5 July 1918) was a French serial killer. She strangled at least 10 children, including her own. She was both convicted of murder and declared insane in 1908; she hanged herself ten years later.
Joseph Gleydson Vacher (16 November 1869 – 31 December 1898) was a French serial killer and necrophile, sometimes known as "The French Ripper" or "L'éventreur du Sud-Est" ("The South-East Ripper") owing to comparisons to the more famous Jack the Ripper murderer of London, England, in 1888. His scarred face and plain, white, handmade rabbit-fur hat composed his trademark appearance. He killed 11 to 27 people, many of whom were adolescent farm workers, between 1894 and 1897.
Marcel André Henri Félix Petiot (17 January 1897 – 25 May 1946) was a French medical doctor and serial killer. He was convicted of multiple murders after the discovery of the remains of 23 people in the basement of his home in Paris during World War II. He is suspected of the murder of about 60 to 200 victims during his lifetime, although the true number remains unknown.Despite showing early signs of mental illness and criminal behaviour, Petiot served in the First World War, graduated from an accelerated medical program, and began a dubious medical career that included performing abortions and supplying narcotics. His political career was marked by scandal, theft, and corruption. During the Second World War, Petiot operated a fraudulent escape network, offering safe passage to those wanted by the Germans for a fee, only to murder them, steal their valuables, and dispose of their bodies. In total, he was suspected of around 60 murders, but the remains of only 23 victims were found in the basement of his Paris home. Captured in 1944, Petiot claimed to be a Resistance hero who killed only the enemies of France. He was convicted of 26 counts of murder and was executed by guillotine in 1946. His life and heinous crimes have been depicted in film and comic books.
