Danish police are sending the first three test cases with DNA evidence to be compared against American genealogical databases as part of a new process enabled by legislation from 2025.
Danish police have taken a significant step in utilizing American genealogical databases by sending their first three test cases containing DNA evidence for comparison. This initiative follows legislation passed by the Folketing in 2025, which allows the police to access commercial databases in certain cases, a process referred to as genetic genealogy. The aim is to provide law enforcement with a powerful tool that could lead to breakthroughs in difficult cases that are otherwise challenging to solve.
Police director Lene Steen expressed optimism regarding this new procedure, highlighting its potential to enhance investigative capabilities. Previously, Danish police have only been able to match DNA evidence from crime scenes with their internal registries. This added capability to analyze DNA against a broader range of genealogical data may link suspects to crime scenes through familial connections, offering new leads in cold cases and unsolved crimes.
The chosen test cases will serve as a practical trial for the agreed-upon process, ultimately guiding future decisions on the expanded use of DNA evidence in investigations. With the successful implementation of this method, there may be significant implications for criminal investigations in Denmark, potentially increasing the rate of case resolution and improving overall public safety.
