Fifteen years on, the Dupont de Ligonnès case still haunts France For more than 15 years, the fate of Xavier Dupont de Ligonnès has remained one of France’s biggest mysteries. The 50-year-old is suspected of having murdered his entire family and burying them in concrete under their home before fleeing the scene. Now, the discovery of an obscure online account – active several years after his disappearance – has reignited speculation that France’s most wanted man may still be alive.
