Xavier Dupont de Ligonnès: Cold-case pioneer faces 'recent life evidence' of suspect

A French prosecutor instrumental in establishing a cold-case unit will participate in a television program focusing on the enduring mystery of Xavier Dupont de Ligonnès. Jacques Dallest, an honorary magistrate and creator of the Nanterre cold-case division, is set to appear on M6's "Appel à témoins" on June 2.

The program promises to unveil "recent evidence of life" concerning the fugitive, who disappeared 15 years ago after the murders of his wife and four children. The show also claims to have found "key, sensible, and credible witnesses." Dallest, author of "Sur les chemins du crime" and "Cold-case, un magistrat enquête," believes that corroborating testimonies on the show could advance the justice in this complex case.

The Xavier Dupont de Ligonnès affair remains one of contemporary France's most significant enigmas. Two primary theories persist: suicide or an elaborate flight abroad. Dallest's involvement underscores the continued public and judicial fascination with the case, highlighting the persistent questions surrounding the suspect's whereabouts and fate.
