THE USE OF 3D MODELING IN FORENSIC EXPLOSIVE EXPERTISE

Abstract

The article is devoted to a new promising method suitable for use in one of the varieties of forensic explosive expertise – situational expertise on the fact of an explosion. In order to solve the problem of establishing the nature and type of explosion, it is necessary to analyze all the damage to build-ings and objects at the scene of the incident in order to determine the center of the explosion and its location. Such studies are situational modeling or situational expertise. The rapid development of information technologies makes it possible to create 3D models of the scene of an incident and use them to conduct situational studies, significantly increasing the effectiveness of operational and investigative actions, and, ultimately, brings real benefits in the investigation of crimes. The article shows the possibilities of using 3D modeling technologies to establish the dynamics of fire development, followed by the establishment of the explosion center and its technical cause, us-ing the example of a real incident - an explosion in the port of Beirut on 04.08.2020. The use of 3D modeling technologies and animation capabilities allows to visualize information about the circumstances of the explosion, which was obtained on the basis of collecting, summarizing and analyzing information obtained from various sources (protocols of the inspection of the place of advent, diagrams, plans, photo and video recordings, witness statements and other documents, as well as expert opinions).
