forensic ballistics

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. For forensic ballistics is important to reconstruct the events of the use of firearms. One way of reconstruction is based on the position of spent cartridges relative to surrounding objects. Often required to establish the fact of secondary reflection in the collision of objects sleeves and find a place on the collision who after this microtraces. Goals and objectives.

Introduction. Conducting forensic ballistic investigations often involve changes to the results of which depend on the findings in many ways. According to local legislation, these measurements must meet certain requirements. Theoretical analysis. Analyzed compliance with the diagnostic techniques of forensic ballistic investigations homemade firing device for assigning it to firearms requirements of the Federal Law «On ensuring the uniformity of measurements».

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.

Introduction. The development of small weapon and structurally similar products, their use for criminal purposes force forensic science and practice to make adjustments to the forensic classification system of firearms over and over again. Theoretical analysis. In forensic ballistics, firearms are classified according to their purpose, type, method of production, barrel length, barrel channel device, number of barrels, etc. By the method of manufacture, groups of factory, artisanal and improvised firearms are distinguished.
