Murder of Estelle Mouzin

Her mother reported the fact she was missing to the local police station shortly after 7:00 p.m.[3] Her disappearance sparked huge media coverage all over the country.

However, after consideration, the police discounted Fourniret because he seemed to have an alibi — namely, a phone call was made from his home at the time of Estelle Mouzin's disappearance.

The scope of the inquiry, led by the Commissioner Jean-Marc Bloch, was unprecedented; more than 130 persons were interrogated by the police and all the houses of the city were searched.

[12][13] On 23 January 2020, Michel Fourniret, in front of judge Sabine Khéris, asserted that his memory "got the better of him", but that he had to be "considered guilty" of Estelle Mouzin's disappearance.

She added that Michel Fourniret had made reconnaissance sightings in the days preceding the abduction, and that one evening he returned from his hunt stating that he had spotted "a beautiful little target".

On 21 August 2020, the lawyer of Olivier declared that his client had been indicted for "complicity" and affirmed that her ex-husband Michel Fourniret had kidnapped Estelle Mouzin on the 9 January 2003 and took her to Ville-sur-Lumes in the Ardennes, “to sequester her” and “that he had raped and strangled her”.

[15] In May 2023, French authorities sought to indict Olivier on charges of being involved in Mouzin's kidnapping and the murders of Joanna Parrish and another woman named Marie-Angele Domece.
