Martin Dumollard was a French serial killer condemned to the guillotine after having been arrested and charged with the deaths of maids from 1855 to 1861. His victims were approached in Lyon by Dumollard, who offered them a nice house in Côtière. Convinced, they would eventually follow him and, during their wanderings on foot, he attacked them. All twelve assaults or attempted assaults occurred in the late 1850s and early 1860s until that of Marie Pichon on May 28, 1861. He was quickly arrested, along with his wife and accomplice, Marie-Anne Martinet, who stole the personal belongings and used them for resale. Their trial took place from January 29 to February 1, 1862: Dumollard was sentenced to death and his wife, twenty years of penal labour. This affair, which preceded that of Joseph Vacher by about thirty years, had a great repercussion in France; it is often considered one of the first cases of a serial killer in France. Dumollard is notably mentioned in Les Misérables by Victor Hugo.
