Child disappearance case revisited

Mathieu Haulbert vanished on June 25, 1983, when he was 10 years old, after leaving a small village in the Verdon area. His disappearance remains unsolved and is now classified as a "cold case" under the jurisdiction of Nanterre.

Parents' long quest for answers

For Mathieu's parents, Lise and Philippe Haulbert, the case represents the final chance to see their decades-long search for answers reach a conclusion. They have tirelessly pursued leads and advocated for renewed attention to their son's disappearance.

Media revival of the case

The case was recently mentioned in an extract from the documentary Affaires sensibles on October 31, 2026. The program is known for revisiting unresolved criminal cases and bringing them back into public and investigative focus.

Cold case division efforts

Nanterre's cold cases division continues to review old cases with new investigative techniques and evidence. This approach has led to the resolution of several long-dormant cases in recent years, offering hope to families like the Haulberts.
