PS08 - Crime Scene Investigation and Coordination
Deparment/unity chief - Forensic Department "Signal-Image-Speech", IRCGN
The National forensic institute of the french gendarmerie (IRCGN) has within its staff a group specialized in the freezing of a scene, whether it's a criminal or an accident one.
One mean of this group is to create a specific “Geographic Information System (GIS)” for each scene. This solution help the IRCGN experts to have a best understanding of the scene and have the capability to analyse in the same system all of the data.
Indeed, a GIS tool represents a precious help in forensic and more specifically in the management of a crime or accident scene, even complex.
The goal is to provide a low cost solution which centralize the data collection from a scene, and visualize this scene and all its evidences without a specific tool. With all these elements, the GIS can improve the analysis of all the evidences between them, their links and with the environment.
The heart of this tool is a free GIS software (QGIS), allowing to organize all the acquired data, in a database. These data, which concern the scene configuration and all its evidence, can be of two kinds : geographical (position of the evidences) and/or attribute (nature of evidences, analyzed/not analyzed, etc...). This database can be updated, regarding the expertises analysis results, but also requested to help investigators or the forensic coordinator in their judicial investigations.
The forensic experts and forensic coordinator have a tool, centered on a GIS solution, which help them to collect, centralize, organize and analyze many kind of informations about evidences from a crime or accident scene. This tool can help investigators to take into account a very complex scene, with a large numbers of evidences and analysis, and thus contribute to the truth manifestation.
