A French serial killer’s ex-wife has been sentenced to a second life term in prison for her part in two murders and a kidnapping.

Monique Olivier, 75, is already in prison after she was convicted in 2008 for her part in Michel Fourniret’s kidnappings, rapes, and murders, according to the BBC.

Olivier was convicted this week in the rapes and murders of Joanna Parrish, 20, in 1990 and Marie-Angèle Domèce, 18, in 1988 as well as the kidnapping of 9-year-old Estelle Mouzin in 2003. Mouzin’s body has never been found. Her ex-husband, who died in prison in 2021, confessed to those murders before his death.

Fourniret ultimately confessed to killing 12 people in France and Belgium between 1987 and 2003 and was convicted on seven deaths, all women or girls, in 2008 and one more in 2018. The 12th person was reportedly a man who has never been identified.

Fourniret was initially arrested in 2003 after a failed attempt to kidnap a 13-year-old girl, but neither he nor Olivier gave up any information under extensive questioning. A year later, Olivier went back to police and told them about the murders and her role in helping lure the victims.

Olivier’s initial sentence in 2008 gave her the possibility of parole after 28 years, and she and Fourniret were ordered to pay 1.5 million euros as “moral compensation” to the families of the victims. Fourniret was given no possibility of parole.

Joanna Parrish’s father, Roger Parrish, said after the trial that the family had “waited a long time.”

“[Olivier’s] presence alone would’ve gained the confidence of all the victims, who would never have believed a woman could’ve been such a part of such an appalling and depraved act.”

The new sentence for Olivier carries the possibility of parole in 20 years.
