The family of Joanna Parrish, including her parents and boyfriend, left a Paris court as Monique Olivier, widow of serial killer Michel Fourniret, recounted the murder of Joanna in 1993. Olivier described her role in luring Joanna into a van and the subsequent attack by Fourniret, who had an obsession with virgins. Olivier, on trial for her involvement in the kidnapping and murders, expressed regret for her actions. The court was shown photos of Joanna before and after her murder, and Olivier claimed to be haunted by the victims' faces. The trial revealed that Fourniret and Olivier had already begun their murder spree by the time they encountered Joanna, who had advertised her services as an English tutor. Olivier is serving a life sentence with a minimum of 28 years for other murders, while Fourniret died in 2021.

Monique Olivier, once perceived as a victim of her ex-husband Michel Fourniret, is now facing a new trial for her complicity in the murders of Estelle Mouzin, Marie-Angèle Domèce, and Joanna Parrish. The public is less familiar with Olivier, who played a significant role in Fourniret's heinous crimes. Her involvement and her own distinct cruelty have been overshadowed by her husband's actions. The trial, which has garnered intense media attention, revisits the couple's crimes and Olivier's deceptive appearance, which masked her role as a sexual criminal and possibly one of the worst in France.

Monique Olivier, the ex-wife of French serial killer Michel Fourniret, has been found guilty of complicity in the murder of British student Joanna Parrish and two other French victims. Olivier, who admitted to the accusations, was sentenced to life imprisonment with a minimum term of 20 years. The trial, which lasted three weeks, concluded with a panel of judges and jurors taking over 10 hours to reach a verdict. Fourniret, known as the 'Ogre of the Ardennes,' was previously jailed for life for the murder of seven other girls and young women. He died in 2021 before he could be tried for the murders of Parrish and two other victims. The trial highlighted the couple's modus operandi, with Olivier luring victims into their vehicle, making them less suspicious. The verdict brings a sense of justice to the victims' families, who have waited decades for this outcome.
