French Investigators Dismiss US Lead Despite Texas Sighting Reports

French investigators have dismissed the American lead in the Dupont de Ligonnès case, citing a lack of tangible evidence, despite a Brewster County, Texas, Sheriff's Office appeal and an alleged 2020 sighting in the region. A retired French police officer has published a book claiming the suspect is alive in the US, a theory French authorities do not currently support.

The essentials

French investigators reject the US lead, despite a Texas sighting report and a retired officer's book claiming otherwise.

French investigators have rejected the American lead in the long-running search for Xavier Dupont de Ligonnès, stating there is no tangible evidence to support the theory that he is living in the United States.

Dupont de Ligonnès is suspected of killing his wife and four children in Nantes in April 2011 before disappearing. He has been the subject of an international manhunt ever since, including a mistaken arrest in Scotland in 2019.

Despite the French position, a Brewster County, Texas, Sheriff's Office appeal was issued to locate him, following an alleged sighting in 2020 of a man matching his description accompanied by a black Labrador. A retired French police officer, Gilles Galloux, has published a book asserting that Dupont de Ligonnès is alive and residing in the United States.

The divergence between American law enforcement action and French investigative conclusions highlights the unresolved nature of the case.

Texas Sheriff Acts While French Authorities Remain Unconvinced

The Brewster County Sheriff's Office issued a formal appeal to locate Dupont de Ligonnès following an alleged 2020 sighting of him with a black Labrador. A retired French police officer's published book supports the US theory. These developments suggest active interest in the American lead at a local law enforcement level, independent of the French investigative position.

French Investigators Find No Solid Basis for US Theory

French investigators have formally rejected the American lead, citing an absence of tangible evidence. The case has already produced one major investigative error — a wrongful arrest in Scotland in 2019 — which may inform the caution French authorities are applying to the Texas sighting claims. The official French stance remains skeptical of the US-based theory.
