Methodological aspects of diagnostic (situational) research of fire-fighting damage of multilayer automobile glass

Abstract

In the article methodical aspects of diagnostic (situational) investigation of gunshot injuries of multi-layer automotive glass are considered. Forensic diagnostics is a process of investigating the properties and state of an object (situation) in order to establish the changes that have occurred in it, the causes of these changes and their relation to the committed crime. According to the authors, it can be argued that in forensic expertology, the methodological issues of modern diagnostic (situational) forensic studies have been developed to a lesser extent, which is explained by the rapid technological development of society and some lag in the introduction of innovative technical means in the practice of specialized expert institutions. Establishing the facts and circumstances of the use of firearms for damage to vehicles requires systematic consideration of all the main aspects of forensic diagnostics: its general methodology, diagnostic tasks that arise in the course of expert research, methods and methods for their solution. The authors analyzed the problematic issues of improving the methodology of forensic-ballistic research in this field. The ways of increasing the effectiveness of the existing methodology and developing a new private methodology are identified through the use of modern methods and technical means of research. The expediency of using specialized software and hardware complexes during the examination of multi-layer automotive glass is shown. The effectiveness of application of specified methods and tools in the mentioned information systems for diagnostic and situational expert studies is analyzed. It has been established that complex wave processes occur in multi-layered automotive glasses with non-plastic deformations due to viscoenergic objects, the investigation of which requires from the forensic expert not only special knowledge in the field of forensic expertise, but also knowledge in related fields such as materials science, material resistance, physical optics, theoretical Mechanics. The methodology for studying multilayer automotive glass should be built on the development of the idea that it is necessary to strengthen the experimental stage of forensic ballistic research by conducting an expert experiment. Achieving the objective results of forensic examination of firearm injuries of multi-layer automotive glass obtained using the methods proposed by the authors to improve the current methods and develop new specific methods requires effective application of modern methodological approaches and innovative technical means.
