Michel Paul Fourniret (4 April 1942 – 10 May 2021) was a French serial killer who confessed to killing 12 people in France and Belgium between 1987 and 2003. After he was arrested in June 2003 for the attempted kidnapping of a teenage girl in Ciney, Fourniret confessed to killing nine people — eight females and one male — in 2004, having been informed on by his then-wife, Monique Pierrette Olivier (born 31 October 1948). Fourniret was convicted of seven of these murders on 28 May 2008 and sentenced to life imprisonment without possibility of parole, while Olivier was given life with a minimum term of 28 years for complicity. In February 2018, Fourniret confessed to killing two more women. On 16 November 2018, Fourniret and Olivier were convicted of the murder of Farida Hammiche, the last of the eight women that Fourniret confessed to killing in 2004. Fourniret was given a second life sentence and Olivier was sentenced to a further 20 years of imprisonment.

He wrote to her of his fantasies of raping and murdering virginal girls; she responded that she would "help" him fulfill those fantasies if he killed her husband, although he never committed this murder. After he was released from prison in 1987, they began a relationship. Soon afterward, he began raping and murdering young girls, with Olivier as his accomplice. Murders On 11 December 1987, Fourniret and Olivier drove, in separate vehicles, to Auxerre. Seeing 17-year-old Isabelle whom the couple had seen a day or two earlier and were walking home from school, Olivier stopped to ask Laville to join her in the car and give her directions, which Laville agreed to do.
