As part of the investigation into the assassination of Estelle Mouzin in 2003, the former wife of serial killer Michel Fourniret, Monique Olivier, will be confonted, this Tuesday afternoon, to several of her former fellow prisoners in who she had confided in the death of the girl, announced her lawyer, Me Richard Delgenes.

After the death of Michel Fourniret, last May, at the age of 79, Monique Olivier is now the only one able to help solve the riddles left by her ex-husband during his hearing at the Paris judicial court by the judge Sabine Khéris instruction.

The body always wanted

The magistrate is responsible for investigating the death of Estelle Mouzin, 9 years old, who disappeared from Guermantes (Seine-et-Marne) on the evening of January 9, 2003. A few months before her state of health deteriorated, Michel Fourniret had recognized with the judge his role in this case. Last April, Monique Olivier finally confessed to having accompanied her ex-husband on January 11, 2003 in a wood of the Ardennes so that he bury the body. Since June 2020, Sabine Khéris has organized eight search campaigns there to try, sometimes in the presence of the ex-wife of the serial killer, to find the body of the girl, without success.

The purpose of these new hearings and confrontations is to "try to determine a place" where the body would be, said Delgenes.

In 2018, five inmates of Rennes (Ille-et-Vilaine) prison, who said they had heard Monique Olivier confide in her ex-husband's actions, had been interviewed by investigators.

Monique Olivier could also be questioned on Wednesday by the judge on the disappearance of Lydie Logé, 29, in 1993 in Orne, according to Me Delgenes.

Complicity in four murders

While two investigations, from 1994 to 1998 and then from 2004 to 2009, had resulted in dismissals, the investigations were relaunched in 2018 after connections established between the DNA traces from organic compounds found in Michel Fourniret's van and the DNA of Lydie Logé's mother.

Monique Olivier is serving a 28-year security measure in Fleury-Mérogis (Essonne) prison for complicity in four of the murders of “the ogre of the Ardennes”.

She is also indicted, also for complicity, in the disappearances of Lydie Logé and Estelle Mouzin, but also of Marie-Angèle Domece at 19 (1988) and Joanna Parrish at 20 (1990).
