Danish police solve decade-old rape case using genetic genealogy techniques

Danish police have cracked a nearly decade-old rape case using advanced DNA technology, reports national broadcaster DR. The 2015 assault on an 89-year-old woman had remained unsolved until investigators applied a method called kinship searching, which identifies potential suspects by matching crime scene DNA with profiles of close relatives in police databases.

The case was on the verge of exceeding the statute of limitations when the breakthrough occurred. The technique, relatively new in Danish law enforcement, analyses genetic material from old evidence to trace family connections, even when the perpetrator’s DNA is not directly on file.

While the report highlights this specific case, it raises broader questions about the expanding use of DNA technologies in Danish policing. Authorities have not disclosed further details about additional genetic investigation methods now in use.
