In April 2011, a quiet home in Nantes, France concealed a crime that would haunt investigators for more than a decade.
Beneath the patio, police discovered the bodies of Agnès Dupont de Ligonnès and her four children, carefully wrapped and buried. There were no signs of forced entry. No struggle reported by neighbors. And one person was already gone.
Xavier Dupont de Ligonnès — husband, father, and the family’s only surviving member — had vanished.
In the days following the murders, Xavier withdrew cash, traveled across southern France, and was last seen on surveillance footage walking toward a remote mountain area. What happened next remains unknown. No body was ever found. No confirmed sightings followed.
Was this a meticulously planned escape? A final act of suicide? Or one of the most successful disappearances in modern criminal history?
In this episode of Three Voices One Crime, we reconstruct the timeline leading up to the murders, examine Xavier’s psychology and financial collapse, and trace every confirmed movement before he disappeared — leaving behind six graves and a question that still has no answer.
