Xavier Dupont de Ligonnès : dans la tête du suspect.

In April 2011, relatives and neighbors of the Dupont de Ligonnès family became concerned. The shutters of the couple's home had been closed for several days. On April 21, 2011, during a search of the property, police discovered five bodies buried under the terrace: those of the mother and her four children. Only the body of the father, Xavier Dupont de Ligonnès, was missing. He immediately became the prime suspect in the quintuple murder. Step by step, his route is traced. Soon, the fugitive's trail goes cold. His last sign of life dates back to April 15, 2011, when he spent the night in a hotel in Var. Since then, there has been no trace of Xavier Dupont de Ligonnès. An international appeal is launched.
