Monique Olivier and Michel Fourniret were placed in custody Tuesday as part of an investigation into the disappearance of Lydie Logé, on December 18, 1993 in the Orne. The investigation was reopened in 2018 by the Argentan public prosecutor, considering that there was "a small probability" that the serial killer was involved.

Serial killer Michel Fourniret and his ex-wife Monique Olivier are both in custody as part of an investigation into the disappearance of Lydie Logé on December 18, 1993, in Saint-Christophe-le-Jajolet, France. Orne, AFP learned Wednesday from the prosecutor of the Republic of Argentan, Hugues de Phily. Monique Olivier was placed in police custody on Tuesday at 2 pm and Michel Fourniret at 3 pm in the Central Office for the Repression of Violence against Persons (OCRVP) in Nanterre.

"A small probability"

Last May, the prosecutor confirmed to AFP the reopening of this investigation in 2018 because there was a "small probability" that the serial killer Michel Fourniret was at the origin of the disappearance of Lydie Logé. "It has been possible to establish a link between DNA traces from organic compounds found in Michel Fourniret's van and the DNA of the family of the missing person" but "the probability of a link is small", investigative techniques and the age of materials, he said. This was shown in February 2019 the results of the examinations ordered by the prosecution for the purpose of comparison of DNA in a preliminary investigation opened in June 2018 by the prosecutor of Argentan, requested by the OCRVP .

The probability of a link with Michel Fourniret is "very tenuous because we are on a technique based on mitochondrial DNA" and not nuclear DNA with which we can have certainties "to almost 100% "he warned. "From where my very great reserve, it is the only" element which the investigators have to feed "Assumption Fourniret which appears for the first time in 2018, had insisted the magistrate.

Two investigations, two non-places

This disappearance has already been the subject of two investigations, from 1994 to 1998 and from 2004 to 2009, both of which resulted in non-occurrences. The investigators had favored the close family circle. Suicide, voluntary disappearance or not, "nothing allowed to privilege a track", specified then the prosecutor.

Michel Fourniret was sentenced in 2008 to life imprisonment for seven murders of young women or girls between 1987 and 2001, preceded by rape or attempted rape. On November 16, 2018, he was again sentenced to life for the 1988 assassination of Farida Hammiche.
