The Dupont de Ligonnès affair continues to fascinate the crowds ... The publication during the summer by the magazine  Society  of a long investigation on the subject has revived the enthusiasm of Internet users for this news item. Xavier Dupont de Ligonnès, suspected of having killed his wife and four children in Nantes in April 2011, has never been found, today giving rise to many hypotheses as to whether he is still alive.

On YouTube, a real business has been created around this affair, with specialized channels on the subject accumulating millions of views. Numerous Facebook groups have also been created to try to resolve the matter. The participants exchange evidence, hunches and press articles, in an attempt to advance the investigation.

Comments, analyzes and hypotheses ...

Driven by the success of Society , the community of the Facebook group "Xavier Dupont de Ligonnès: Inquiry and Debate" has experienced a considerable influx of new subscribers in recent days. This group has garnered thousands of new members since the publication of the Society article , reaching nearly 9,000 subscribers today. On this Facebook page, amateur investigators share online their comments, analyzes and hypotheses about Xavier Dupont de Ligonnès (XDDL).

“I think his accomplice is not a relative, but more of a person he had to pay for not speaking. As a result, this person will surely never speak for fear of reprisals ”, explains one of the Internet users. "I do not imagine him in Europe, the affair made a lot of noise here, and he would not have taken this crazy risk to be recognized", explains another assiduous member of this group "of reflection and investigation ".

When Facebook reveals information

Among the flood of comments and hypotheses, sometimes very far-fetched, information has already been revealed by Facebook groups, in particular concerning Agnès, the wife of Xavier Dupont de Ligonnès. "They made it possible to exhume the messages of Agnes who complained about her couple on forums and those of her husband on the cite-catholique.org site, with methods sometimes bordering on legality", explains Thibault Raisse , one of the authors of the Society's investigation .  Information has also emerged, in particular on the psychology of Xavier Dupont de Ligonnès. A sign of this success, police officers have also joined these Facebook groups, as have journalists working on the subject.

This phenomenon does not only affect the Xavier Dupont de Ligonnès affair. Other unsolved crimes have aroused the interest of Internet users in recent years, such as the case of little Grégory. Since the broadcast on Netflix at the end of November of the documentary series Grégory, which looks back on the kidnapping and assassination in 1984 of Grégory Villemin, Internet users have reopened Facebook groups to try to solve this case, which has never been clarified. .
