Modernity to hope to solve a 36-year-old affair.
As revealed by Le Parisien in December, a stylometric expertise took place in the context of the Grégory Villemin affair, in order to identify the crows author of several anonymous letters gravitating in the investigation.
According to France Info radio, this expertise has just been added to the investigation file.
"I confirm the payment of this stylometric expertise in the file", indicates, without further details, the Attorney General of Dijon Thierry Pocquet du Haut-Jussé.
According to another information, relayed this time by our colleagues from 20 Minutes and confirmed with the Parisian, this stylometric expertise would have made it possible to identify Jacqueline Jacob, the great-aunt of little Grégory, as the main author of these anonymous letters.
A "hoax" according to the Jacob couple
In 2017, graphology expertises, which analyze handwritten writings, attributed a letter from 1983 to Jacqueline Jacob, Grégory's great-aunt.
She and her husband Marcel had been indicted but this procedure was canceled in May 2018 for procedural flaw.
Last December, Le Parisien announced the identification of a person in the new expert report.
The Jacob couple once again denied, in an interview with the local press in January, that they were the crows.
The defense of the Jacob couple recently described the new stylometric expert report as a "hoax", even before seeing the conclusions.

Stylometry, already used in American courts but not in France, studies the vocabulary, syntactic structures, the length of sentences… in order to determine the author of a text.
This expertise was carried out in Switzerland and aims to identify the crows who had written anonymous letters threatening the parents of little Grégory, found at 4 years old with bound hand and foot in Vologne (Vosges) on October 16, 1984.
Confirming the entry into the file of the expertise, François Saint-Pierre, one of the lawyers of Christine and Jean-Marie Villemin, the parents of Grégory, was very circumspect.
"We remain extremely cautious as to the interpretation which can be made of this report and the consequences which could be drawn from it", he warns.
Kinship DNA or the resolution of several "cold cases"
The Gregory case, investigated at the Dijon Court of Appeal, was recently relaunched, the justice having accepted in January new DNA expertise requested by Christine and Jean-Marie Villemin.
This concerns in particular research in “DNA of kinship”, making it possible to link a genetic fingerprint with others, resulting from the same kinship.
The research in "DNA of kin" aims to verify the conformity of the genetic fingerprints with those present in the National Automated File of the genetic fingerprints (FNAEG).
In recent years, it has made it possible to resolve several “cold cases” (closed cases), in particular the Élodie Kulik case, raped and murdered in 2002.
