France
Nearly fifteen years after his disappearance, the Dupont de Ligonnès affair has taken a new turn. A witness appeal issued in the United States is reviving speculation around one of France’s most wanted fugitives.
On March 25, 2026, authorities in Brewster County, Texas, released a public appeal following a report considered credible.
A man resembling Xavier Dupont de Ligonnès was allegedly seen near the Mexican border, in a remote area of southern Texas.
According to local officials, the individual was accompanied by a black dog, possibly a Labrador, a detail that quickly drew attention.
Notably, the reported sighting dates back to 2020, but has only recently been made public as part of renewed investigative efforts.
Authorities are now urging anyone who may recognize the man or have relevant information to come forward.
Missing since April 2011, after the bodies of his family were discovered in Nantes, Xavier Dupont de Ligonnès has never been found.
Over the years, hundreds of reported sightings have surfaced worldwide, none of which have led to a confirmed breakthrough.
This latest American lead aligns with a long-standing theory: that he may have fled abroad, possibly to the United States — a country he was familiar with.
While this new development has reignited media attention, investigators remain cautious.
At this stage, no concrete evidence confirms that the man seen in Texas is the fugitive.
Some theories still suggest he may have died shortly after his disappearance, although no definitive proof has ever been established.
