Perhaps a crucial turning point in this affair.
The Dijon Court of Appeal, where the case has been investigated since 1987, announced on Wednesday that it would authorize new expertise, in particular DNA.
Request made by the lawyers of Jean-Marie and Christine Villemin, in the hope of finally clarifying the assassination of little Grégory, more than 36 years after the facts.
On December 16, the lawyers of Jean-Marie and Christine Villemin, had pleaded to ask for new expertise, in particular focused on DNA, the only one capable, according to several players in the case, of solving one of the most enigmatic various facts French criminal annals.
Nine DNA traces taken from anonymous mail
Previous genetic expertise had not yielded anything but, still determined to bring out the truth about the death of their child, the Villemin relied on the search for "kinship DNA", a method that allows to link a genetic fingerprint with 'others from the same family and listed in the National Automated DNA File (FNAEG).

Grégory's parents wanted the research to focus on nine DNA traces taken from anonymous letters, a syringe and the clothes of the child, found dead on October 16, 1984 in the waters of La Vologne, in Docelles (Vosges).
The “kinship” method, practiced in France since 2012, has made it possible to resolve several “cold cases”, such as the Élodie Kulik case, raped and murdered in 2002, or the case of the rapist in Sénart (Essonne), confused in 2015, 20 years after the first attacks.
An interminable affair
Christine and Jean-Marie Villemin also requested new genetic samples from several people as well as the use of a "genetic robot portrait", which makes it possible to determine the color of a person's hair or eyes.
Already rich in twists and turns, the case had a new thunderclap in 2017 with the indictment of Marcel and Jacqueline Jacob, the great-uncle and the great-aunt of Grégory then aged 72, and Murielle Bolle, 48 years at the time and key figure in the affair.
These three indictments were canceled in May 2018 on procedural points.
