Fifteen years after the Nantes killings, the mystery surrounding Xavier Dupont de Ligonnès remains unsolved. Gilles Galloux, a former police officer specialized in cybercrime, is determined to uncover the truth behind Ligonnès's disappearance. He presents a theory suggesting that Ligonnès meticulously planned his survival and escape to America rather than ending his life as many believe.

Galloux is described as a robust figure with a distinctive appearance, and he might soon become just as recognized as the fugitive he seeks. His insights and experiences from three and a half decades in law enforcement lend credibility to his claims. He outlines how Ligonnès could potentially have altered his identity and sustained his life hidden away, despite the extensive manhunt and media coverage over the years.

The implications of Galloux's theory challenge the prevailing narrative about Ligonnès's fate and provoke further investigation into the possibility of his continued existence. If true, this could mean that the key to solving one of France's most infamous mysteries lies across the Atlantic, opening a complex dialogue on issues of identity and evasion in the age of digital surveillance.
