Monique Olivier, the ex-wife of serial killer Michel Fourniret, was heard in Paris court on Thursday. "The stake is the starting point of the official opening of the Fourniret runway" in the investigation into the disappearance of Estelle Mouzin, in 2003, according to the lawyer Monique Olivier.

The ex-wife of the serial killer Michel Fourniret, Monique Olivier, was heard Thursday at the Paris court by the investigating judge investigating the disappearance of Estelle Mouzin in 2003, it was learned from of his lawyer. Monique Olivier was to be interrogated by Judge Sabine Khéris, who recently recovered the investigation initially conducted in Meaux, on the alibi of her ex-husband on the day of the disappearance of the girl in 2003, in Guermantes (Seine-et- Marne), according to Richard Delgenes.

The serial killer had said he had called his son to wish him a birthday from his home in Sart Custinne, Belgium, the day of the disappearance, which seemed to exclude his presence in Guermantes. An appeal attested by telephone records. Monique Olivier, who had initially confirmed that his former companion had made this call, seems to have recently returned to this version.

Michel Fourniret has always disputed his involvement in the Mouzin case

"Is this alibi going to stand up to Monique Olivier's hearing, I'm not sure, we'll see," the lawyer told reporters. "I think the challenge is the starting point for the official opening of the Fourniret runway" in the Estelle Mouzin affair, said Delgenes. "I know that we expect this hearing a particular revelation".

While 9 years old, Estelle Mouzin disappeared on January 9th, 2003 while returning from the school to Guermantes, village located 250 km from Sart-Custinne. His body was never found and the many tracks considered by the investigators gave nothing. At the beginning of 2007, the police had for the first time dismissed in this case "the ogre des Ardennes", sentenced to life for eight murders.

Six years later, the expertise of thousands of hairs and hair taken from her car had also not found traces of the girl. Michel Fourniret's lawyer had then recalled that his client denied any connection with the case. Interviewed by the investigators at the end of 2017, Fourniret had once again claimed to have "nothing to do with the case" Mouzin. Faced with the police officers of the Versailles PJ, who had already heard three times in the past on this issue, he always challenged his involvement every time, told AFP a police source.
