The aim of this study was the genetic identification of Nazi repression victims. Human remains were found in 2011 in the area of former military training ground BRUS in Lodz. Genetic tests were performed upon the request of the Departmental Commission for the Prosecution of Crimes against the Polish Nation of the Institute of National Remembrance in Lodz. The research material was provided by the Institute of Archaeology (University of Lodz). It consisted of bones and teeth which were exhumed from mass Grave No 7. As a reference material we used a buccal swab collected from the putative son of one of the victims. Genomic DNA was extracted from the skeletal samples using the PrepFiler BTA Forensic DNA Extraction Kit. DNA was amplified using the AmpFlSTR Identifiler Plus PCR Amplification Kit and analyzed using an AB 3500 genetic analyzer. The obtained results showed 12 male genetic profiles. The analysis excluded paternity of 10 investigated victims. The genetic data of the remaining samples did not allow for paternity settlement.
