In the paper the authors present results of the postmortem examination of the burnt body of an unidentified young man NN, who was suspected of being kidnapped, held in custody and finally burnt. During the autopsy dental identification was carried out and its results were compared to the dental card of the chosen man. Toxicological examinations of alcohol, CO, drugs and medicines were negative. Additionally, for individual identification, the analysis of blood DNA polymorphism was carried out in the following loci: CSF1PO, TPOX, TH01, F13A01, VWA, F13B, HPRTB, D16S539, D7S820, D13S317 (STR systems), D1S80 and also DQA1, LDLR, GYPA, HBGG, D7S8, GC. The results of the DNA polymorphism in the deceased were compared to those obtained in putative parents. Statistical analysis of the obtained results of the DNA analysis allowed to find out that the man NN was the son of H.E. and R.E. This comprehensive medico-legal examination allowed for identification of the deceased.
