The aim of this study was to make a head start with unveiling transnational spatial patterns in offending. To that end, data are used from DNA profile exchange between The Netherlands and eighteen other EU member states that have implemented EU legislation on forensic cooperation. Information was collected on all DNA stains entered into the database, including the region in The Netherlands where the stain was secured, the type of crime, and how many matching DNA profiles had been identified in each of the other eighteen countries. The results suggest that currently the profiles of offenders who are active in other Prüm countries make up for about 4 percent of all DNA stain profiles in the Dutch DNA database. The highest share of cross-border matches is found in the southeastern part of The Netherlands, where The Netherlands borders one of the most densely populated regions of Germany.
