In 2001 in the East of France, a passenger car was used as a weapon to impact a bicycle and kidnap a female teenager. The investigators interpreted first the scene as a hit and run accident. After a certain time, they reconsidered their initial assessment as a crime after taking into account some forensic traces and facts. Some specialists of the forensic Vehicle department of the IRCGN Laboratory (Institut de Recherche Criminelle de la Gendarmerie Nationale in France) examined the crime scene after the event. They searched the scene for forensic traces; collected them and analysed them to exploit their clue potential.
In a first step, different forensic traces were thus analysed in order to identify the offender vehicle: debris of automotive headlights, automotive paint chip and polymer transferts on the victim’s bicycle, tyre prints, skidmarks on the road. In a second step, after identifying the offender vehicle, a road accident analysis was conducted by the road accident analysis expertise unit of the IRCGN’s vehicle department, in order to determine the vehicle handling in the pre-crash phase and its impact speed. In addition to the kinematics reconstruction work, this study enables us to supervise other close topics like mechanical diagnosis and further exploitation of some traces. Matter and morphological approaches were notably applied to study a system of skid marks on the road at the scene.
