Reconstruire

Situer des évènements dans le temps est une question essentielle en science forensique, de même que le transfert et l'identification. En effet, si une personne déclare avoir été sur les lieux d'un crime à un autre moment que l'évènement en question, la trace laissée (transfert) sur les lieux par cette personne (identification) perd toute signification. La pertinence de la trace est donc étroitement liée à la notion de temps. Les difficultés rencontrés lors de l'étude de la datation de différents type de traces ont crées une controverse mondiale sur la validité des méthodes proposées jusqu'ici, particulièrement en regard de la responsabilité de l'expert scientifique face à la justice. Si l'on considère la récurrence de cette problématique en sciences forensiques, une approche systématique ainsi qu'une meilleure compréhension fondamentale de la détermination de l'âge d'une trace est définitivement nécessaire. Cela représente un grand défi, puisque les processus de vieillissement sont influencés par plusieurs facteurs qui peuvent considérablement accélérer ou ralentir le vieillissement. Ceux-ci devront être étudiés de manière approfondie et peuvent être classés en trois groupes principaux : (i) la composition initiale de la trace, (ii) le type de substrat sur lequel se trouvent les traces, et (iii) les conditions de stockage. Pour ces raisons, l'objectif est donc plus de déterminer un intervalle de temps durant lequel la trace a été déposée, plutôt qu'une date précise. Finalement, une interprétation des résultats selon une approche probabiliste (par ex. basée sur une inférence de type Bayesienne sous deux hypothèses alternatives) semble la plus appropriée. Le développement de cette approche globale fait l'objet d'un ambitieux programme de recherche soutenu par le Fonds National Suisse de la Recherche Scientifique.
