France's Most Wanted Aristocrat May Have Been Spotted in Texas After 13 Years

One of France's most wanted men, Xavier Dupont de Ligonnès, may have been spotted in Texas years after he vanished. The aristocrat is suspected of killing his wife and four children in Nantes in 2011. Despite numerous reported sightings, his whereabouts remain unknown. The case began in April 2011 when the bodies of Agnès Dupont de Ligonnès and her four children were discovered buried beneath a concrete terrace at their Nantes home. Xavier, the husband and father, had disappeared without trace. Investigators initially considered whether he had taken his own life or fled the country.

Over the years, more than 1,700 sightings of Dupont de Ligonnès have been reported to French authorities. One tip led to a detention in Scotland, but the man held was later confirmed not to be him. Another report placed him at a convent in Doubs, France, though nothing was verified.

In 2020, Brewster County Sheriff Ronny Dodson revealed that a local resident had met a man matching Dupont de Ligonnès' description in South Brewster County. The account mentioned a black Labrador, a detail that aligned with past reports. The sheriff's office even posted a public appeal on social media, asking for witnesses who might have seen him.

Retired French police officer Gilles Galloux has long believed Dupont de Ligonnès could be hiding in the US, particularly in Texas. However, as of March 2026, French judicial authorities in Nantes have not confirmed any specific follow-up on the Texas reports. Standard procedures involve cross-checking tips through Interpol and local investigations, but no official verification has been made public. The search for Xavier Dupont de Ligonnès continues over a decade after the murders. While sightings persist, including the 2020 report in Texas, authorities have yet to confirm his location. The case remains open, with French officials still pursuing leads.
