firearms identification

Introduction. Conducting research on identification of handguns Shoot the bullets and shells to the most complex types of forensic ballistic examinations. Glare surface and cylindrical concave surface trace of the striker on the primer sleeve difficult enough for optical microscopic examination. Also relevant is the forensic ballistics problem of obtaining copies of tracks for storing and mailing expert divisions. Experiments al part (procedure).

Introduction. The paper analyzes the effectiveness of the application of the method of successively matching traces (CMS method) and the probabilistic method for substantiating the forensic identity of the overlapping secondary traces on fired bullets. Theoretical analysis. The theoretical foundations of the CMS method and the probabilistic method are considered. It is shown that the second method is formed on the basis of two mutually complementary probabilistic models.
