Xavier Dupont de Ligonnès Case: Stunning Twist as the Fugitive May Have Posted Messages as Late as Six Years After the Family Murders
A new investigation by Ouest-France, published on Monday, June 1, says a previously overlooked account on a Catholic forum may have been used by Xavier Dupont de Ligonnès years after he vanished in 2011. The account, called “Epsilon,” reportedly remained active until 2017 in Nantes, adding a new twist to one of the most enduring criminal mysteries in France.
Dupont de Ligonnès has long been known to have posted on cite-catholique.org under the usernames “Chevy” and later “LIGO.” His final messages under the LIGO profile were published just days after the bodies of his wife and four children were discovered in Nantes. Those posts had already made the forum an important source in the investigation into the quintuple murder.
The latest findings focus on a third profile, “Epsilon,” which investigators and amateur researchers say shows striking similarities to the earlier accounts. Ouest-France says the account’s writing style was examined using stylometry, a method that compares authors’ habits in syntax, vocabulary, punctuation, recurring expressions and argumentation. According to the newspaper, the analysis covered 6,500 forum profiles.
The similarities cited include repeated phrases, identical turns of expression, and unusual punctuation patterns, including frequent question marks and exclamation marks. The account also used expressions such as “CQFD” and “Liste non exhaustive,” which were said to echo habits seen in the writings linked to Dupont de Ligonnès. The newspaper also says the forum posts were compared with private writings found in the investigation file.
One element stands out in particular. A handwritten letter attributed to Dupont de Ligonnès in 2008 reportedly discussed contradictions in the Bible involving three figures from the Old Testament: Baescha, Jojakin and Achazia. According to Ouest-France, the “Epsilon” account later published messages focused specifically on those same three biblical figures, at a time when no other forum member had discussed them.
Ouest-France says no other profile among the thousands analyzed showed the same level of convergence with the writing attributed to the fugitive. While the findings do not amount to proof, they add a new layer to the unresolved case and will likely fuel fresh speculation about whether Dupont de Ligonnès may have survived beyond 2011.
The disappearance of Xavier Dupont de Ligonnès remains one of the most closely followed criminal cases in France. With no confirmed trace of him found since the events in Nantes, any new lead draws intense public attention. This latest report does not close the case, but it may reopen debate over his possible movements after the murders and whether the man sought by French police continued to communicate online under another identity.
