MOLECULAR-GENETIC STUDY OF DNA OF MATERIAL EVIDENCE OF BIOLOGICAL ORIGIN FOR HUMAN IDENTIFICATION

This study is devoted to the analysis of data on the use of modern high-precision genetic research (genotyping) of certain material evidence of biological origin in the course of forensic medical examination for identification of a person in criminal proceedings or in cases related to the identification of persons during military operations and mass migration. The author paid attention to some issues of modern methods of examination of sweat, saliva, urine, hair and nails, which are now widely used in the practice of a forensic expert and a lawyer both in the medical and biological laboratory of the Bureau of FFI and in private structures Genotyping of the listed objects, which is being implemented in everyday expert practice, can give a clear answer when conducting identification of a person, and the questions of «compliance» or «non-compliance» of samples in these cases disappear. Modern research methods also include the use of gas chromatography-mass spectrometry to detect drugs and other substances, as well as trace elements in the submitted hair samples for identification research. Such knowledge about traditional research and the latest capabilities of modern high-tech diagnostics of various biological samples is very relevant in the practical activities of forensic experts and lawyers at the present stage.
