Number of matches

The Institute of Forensic Medicine at the University of Zurich compares the DNA profiles with the Swiss DNA database and analyses the results on behalf of the federal authorities. The evaluation results are then sent via a secure data line to fedpol’s AFIS DNA Services division, which operates the DNA database. The Biometric Identification division then supplements the pseudonymised results with the corresponding personal and case data, and transmits the full report to the requesting authority.

If a personal profile matches traces from the scene of a crime it is known as a “match”. DNA matches play an important role in investigating many types of offences. In relation to the total number of registered cases, there is a considerably higher number of DNA matches connected to serious offences such as homicide or robbery, as opposed to offences such as theft or damage to property.

In 2019, CODIS turned up 5 000 matches, distributed over the following type:
