Overview

• Ariane Guillot, 25, was fatally stabbed in daylight on April 18, 2001 in Nice’s Parc de la Colline du Château while walking with her three-year-old nephew, and robbery was quickly ruled out.
• The Pôle des crimes sériels/non-élucidés in Nanterre published a new ‘En quête d’indices’ video showing the crime scene and a 3D model of the knife to prompt tips from the public.
• Reopened work includes fresh genetic testing, technical examination of the wound, morphoanalysis of blood traces, and input from OCRVP psychocriminologists.
• A male DNA profile was recovered at the time, but repeated analyses have not produced a match, and a 2024 custody ended with the individual ruled out.
• Tips will be processed by the OCRVP and Nice judicial police as part of the pôle’s fifth national appeal, which aims to reach residents and visitors who may recall overlooked details.
