Grégory Villemin (24 August 1980 – 16 October 1984) was a French boy from Lépanges-sur-Vologne, Vosges, who was abducted from his home and murdered at the age of four.

[6] At 5:30 pm, Gregory's uncle Michel Villemin informed the family he had just been told by an anonymous caller that the boy had been taken and thrown into the River Vologne.

[8] At 9:00 pm, Grégory's body was found in the Vologne with his hands and feet bound with rope and a woollen hat pulled down over his face.

[16] In December 2008, following an application by the Villemins, a judge ordered the case reopened to allow DNA testing of the letters, the rope found on Grégory's body, and other evidence.

[4] On 14 June 2017, based on new evidence, three people were arrested: Grégory's great-aunt and great-uncle, as well as an aunt—the widow of Michel, who died in 2010.

[19] In a farewell letter to a local newspaper, Lambert cited the increasing pressure he felt as a result of the case being reopened as the reason for ending his life.

[21] However, the statements Bolle made while not in custody remain in the file, including the initial allegations against Laroche that she subsequently retracted.

[23] The murder and investigation have been the subject of several documentary series including The Curse of the Vologne (France 3 2018) and Who Killed Little Gregory?

The writer Marguerite Duras (played by a chain-smoking Dominique Blanc) is depicted in a particularly damning light, as she insinuates herself into the investigation by accusing the mother of the crime, based on no evidence except her own fabricated psychological theories, helping to whip up a judicial witch-hunt.
