Swedish Police Achieve 150% Increase in DNA Match Success with New Forensic Tech

Sweden's forensic capabilities have taken a significant leap forward with the introduction of advanced DNA analysis technology, leading to a 150% surge in successful DNA match searches since spring 2025. The National Forensic Centre (NFC) has been at the forefront of this breakthrough, deploying innovative software tools that dramatically enhance the detection and identification of suspects from complex DNA samples.

The journey began in 2022 with the adoption of DNAxs, a Dutch-developed software tailored to analyze mixed DNA traces where samples contain genetic material from multiple individuals. This software has enabled investigators to extract valuable data from previously unusable DNA evidence, as noted by Staffan Jansson from the NFC.

Building on this progress, May 2025 saw the rollout of the Probrank module, which expanded the analytical scope by allowing comparisons against the entire police DNA register, rather than limiting analysis to known suspects. This enhancement has been pivotal, resulting in over 5,800 unique person matches across various investigations. The new technology not only strengthens investigative outcomes but is also believed to contribute to addressing Sweden's rising prison population by identifying suspects who might otherwise have remained at large.

While quantifying the direct effect on convictions remains challenging, the combined impact of DNAxs and Probrank marks a transformative phase for forensic science in Sweden. These advancements boost the police’s ability to solve crimes with complex genetic evidence, signaling a promising future for law enforcement and criminal justice in the country.
