What happened
Marcel Lychau Hansen became known as “Amagermanden” after investigators connected him to a long series of sexual attacks and murders around Copenhagen.
The investigation
DNA comparison across old and newer crime scenes was crucial in establishing links that had gone unrecognized for years.
What the courts or investigators concluded
Hansen was convicted of multiple violent offenses including murder and rape and received a life sentence.
Why the case remains significant
The case is a major Danish example of how DNA databases and cold-case comparison can reveal that crimes separated by many years were committed by the same offender.
Case context
Crime by Region organizes cases geographically so readers can move from one file to other investigations from the same country. For unresolved or contested cases, the wording above reflects the distinction between confirmed events, investigative theories and findings actually established in court.
