The laboratory of forensic science, directed by Christel since February 2023, is like a fortress, a secure building of 11,000 m² spreads over 5 levels. The facility houses 170 employees, including experts specializing in various fields like genetic fingerprinting, papillary revelation, and ballistics.
The main objective of the forensic police is to link crime scenes with their perpetrators by analyzing evidence collected on-site, known as “seals.” The director explains that the analysis times vary, with some being processed quickly, while others can take months due to the volume of evidence.
After several years leading the laboratory, Christel firmly believes that no perfect crime exists. Criminals often leave traces behind, such as DNA or fingerprints. She recalls a case where a husband murdered his wife, dismembered her, and traveled on vacation, leaving a crucial piece of evidence on the trash bag.
Sometimes, investigations lead to evident clues, like a military suspect leaving his pullover at the crime scene. However, criminals can also mislead investigators by planting false evidence, like a cigarette butt. Despite the intrigue surrounding forensic science in TV shows like “CSI,” Christel stresses that the reality is both true and false, noting that French forensic experts do not work in the same dramatic fashion as TV portrays.
