Implementation of modern three-dimensional modeling methods in the process of forensic medical investigation of gunshot injuries caused by medium caliber automatic firearms.

Abstract

We draw attention to three-dimensional (3D) modelling, which current researchers are increasingly incorporating into the forensic medical examination process of firearm injuries. The aim of the study. To implement the three-dimensional spatial reconstruction of gunshot injuries into the process of their forensic investigation by studying morphological signs of injuries, caused by medium caliber automatic firearms (Czech CZ83 automatic pistol). Material and methods. We used the Czech CZ83 automatic pistol loaded with 7.65×17mm browning as a medium caliber firearm. The ballistic clay Roma Plastilina No. 1, manufactured in the USA for bench ballistic tests, was used as a target and a gunshot trace reconstructing material. The series of experiments consisted of 15 gunshots; then the main morphological elements of the skin wound, subcutaneous adipose tissue of the pig and the entry, middle and exit wound channels were investigated, i.e. they were photographed, subjected to photogrammetry and converted into the three-dimensional format with the help of graphic design software “Agisoft PhotoScan” and “3ds max”.
