Birthday, Family & and Marriage

Monique Olivier was born on October 31, 1948 (age: 74 years, as of 2023), in Pont-Sainte-Maxence, a small town in northern France. Her parents were Roger Parrish and Pauline Murrell, a railway worker, and Pauline Murrell, a housewife. She had three siblings: Hudson, Lucie, and Thibault. According to her brother Hudson, she was a shy and introverted child, who suffered from a lack of affection from her parents. She was also bullied at school for being overweight and wearing glasses.
She married her first husband, Pierre, when she was 19 years old. They had a kid name, Selim Olivier, but the marriage was unhappy and abusive. She divorced Pierre in 1982 and moved to the Ardennes region with her kids. She worked as a nurse and a carer for the elderly and lived a lonely and isolated life.
In 1986, she responded to an ad in a Catholic magazine, looking for a pen pal. The ad was placed by Michel Fourniret, who was serving a prison sentence for raping several women. She and Fourniret began to exchange letters and soon developed a twisted relationship. In their correspondence, they allegedly made a pact: Fourniret would kill Monique’s ex-husband, and she would help him find young virgins to rape and murder.
Monique married Fourniret in 1989, while he was still in prison. She was waiting for him at the gate when he was released in October 1987. They moved to a house in Sart-Custinne, Belgium, where they lived with her children and Fourniret’s son from a previous marriage.

A Reign of Terror

Monique Olivier and Michel Fourniret embarked on a reign of terror that lasted for 16 years. They targeted young women and girls, mostly hitchhikers, students, or runaways, who they lured into their van or their house. Fourniret would rape and strangle them, while she would watch or assist him. They would then dispose of the bodies in remote locations, such as forests, lakes, or cemeteries.
Some of their victims were:
- Isabelle Laville, 17, who disappeared on December 11, 1987, in Auxerre, France. Her remains were found in 2006.
- Fabienne Leroy, 20, who was abducted on August 28, 1988, in Châlons-en-Champagne, France. Her body was found the next day.
- Jeanne-Marie Desramault, 22, who vanished on March 18, 1989, in Charleville-Mézières, France. Her remains were found in 2004.
- Elisabeth Brichet, 12, who went missing on December 20, 1989, in Namur, Belgium. Her remains were found in 2004.
- Natacha Danais, 13, who was kidnapped on November 21, 1990, in Rezé, France. Her body was found two days later.
- Céline Saison, 18, who disappeared on May 16, 2000, in Charleville-Mézières, France. Her remains were found in 2003.
- Mananya Thumpong, 13, who was abducted on May 5, 2001, in Sedan, France. Her remains were found in 2003.
Monique Olivier played a crucial role in the crimes, as she would act as a bait or a reassurance for the victims, who would not suspect a woman of being involved in such atrocities. She would also help Fourniret to restrain, drug, or dispose of the victims. She later claimed that she was afraid of her husband, and that he threatened to kill her or her children if she did not obey him.
Arrest, Trial, and Conviction
Monique Olivier and Fourniret were arrested in June 2003, after a 13-year-old girl managed to escape from Fourniret’s van in Ciney, Belgium. She gave the police his license plate number and described Olivier as his accomplice. The police searched their properties and found evidence linking them to several unsolved cases. Olivier initially denied any involvement, but later confessed and implicated Fourniret in exchange for a reduced sentence. She also agreed to cooperate with the investigators and show them where some of the bodies were buried.
Olivier and Fourniret were tried and convicted in 2008 for the murders of seven girls and young women. Olivier was sentenced to life imprisonment with a minimum term of 28 years for complicity, while Fourniret was given life imprisonment without the possibility of parole. In 2018, they were both given additional sentences for the murder of Farida Hammiche.
Olivier received 20 years and Fourniret another life sentence. In 2021, they were both found guilty of the murder of Joanna Parrish and the kidnapping of Estelle Mouzin. Olivier was given another 20 years and Fourniret a third life sentence. Fourniret died in May 2021, while Olivier is still serving her sentence in Fleury-Mérogis prison.
Public Perception and Media Portrayal

Monique Olivier’s role in Fourniret’s murders has been the subject of much debate and controversy. Some have argued that she was a victim of Fourniret’s manipulation and domination and that she acted under his influence or out of fear. Others have claimed that she was a willing and active participant and that she shared his fantasies and motives. Olivier herself has given contradictory statements about her involvement and responsibility. She has expressed remorse and regret for some of her actions, but also justified and minimized others. She has also accused Fourniret of lying and hiding other crimes from her.
Olivier’s personality and psychology have also been analyzed by various experts and journalists. Some have described her as a cold, calculating, and narcissistic woman, who enjoyed playing the role of a mother and a nurse, while secretly helping her husband kill innocent girls. Others have portrayed her as a fragile, insecure, and dependent woman, who suffered from low self-esteem, depression, and suicidal tendencies, and who was unable to resist Fourniret’s charm and authority.
Olivier’s story has been the subject of several books, documentaries, and TV shows. The most recent one is the Netflix series “Monique Olivier: Accessory to Evil”, which was released in March 2023. The series features interviews with Olivier, Fourniret, their lawyers, prosecutors, investigators, psychologists, journalists, and some of the victims’ families. The series explores Olivier’s background, relationship with Fourniret, participation in his crimes, and current situation in prison. The series also raises questions about Olivier’s credibility, motives, and remorse, and whether she can ever be forgiven or redeemed.
