DNA databases are proving to be a powerful tool in solving crimes, as seen in the recent Louvre heist case. French authorities used the database to track down suspects within under a week, thanks to DNA left behind by the thieves. The system has grown significantly since its inception in 1998 and now includes profiles from over 4.4 million individuals. This widespread database allows investigators to access not only European but also international DNA databases.
The French DNA database is similar to the US Combined DNA Index System, with some key differences. While both systems contain millions of profiles, France’s database has a more restricted approach, focusing on convicted offenders and those suspected of serious crimes. In contrast, the US system includes crime scene DNA profiles as well as data from consumer genealogy databases.
The growth of these databases is largely due to their effectiveness in solving cold cases and other high-profile crimes. A recent example is the use of DNA in linking a suspect to an attempted rape committed over two decades ago. The French judicial system’s reliance on DNA has also led to improvements in forensic investigation techniques, with some experts predicting that DNA will play an increasingly crucial role in future investigations.
However, concerns have been raised about the potential misuse of these databases and the impact on individuals’ privacy rights. France is currently considering legislation to allow access to private foreign companies specializing in genealogical testing for serious crimes left unsolved for over 18 months.
