“…This task can be particularly effectively addressed by identifying На умовах ліцензії CC BY 4.0 barrel imprints on the skin's surface, left by the specific firearm used (stamp marks). However, such a morphological feature can only be detected in cases of close-range shots, which occur relatively infrequently [14,15].…”

Spatial 3D modeling has become one of the modern and most accurate evidential methods of research, carving out its niche in various fields of medical science and practice. Therefore, our focus has been on laying the groundwork for its implementation in the process of conducting forensic medical examinations of gunshot injuries, which have garnered significant attention from all forensic physicians, particularly after unprovoked aggression from Russia and the onset of active hostilities in our country. The aim of the study was to improve the forensic medical diagnosis of projectile type in injuries from automatic firearm AKS-74U chambered in 5.45x39 mm caliber by utilizing spatial 3D modeling of specific elements within the wound channel. The entire series of experimental shots was conducted using an AKS-74U firearm, with a bullet caliber of 5.45x39 mm. As the research material, Roma Plastilina Number 1 ballistic clay, manufactured in the USA, was used for conducting standardized ballistic tests according to NIJ (National Institute of Justice) and HOSDB (Home Office Scientific Development Branch) standards. The series of experiments consisted of 15 gunshots; then the physical characteristics of the bullet, main morphological elements of the wound of skin and different portions of wound channel were investigated (195 measurements in general). The morphological features of individual elements within the wound channel were measured using conventional measurement tools, and also after their 3D modeling using graphic editors such as "Agisoft Photoscan" and "3ds max." Direct and strong correlations (ranging from 0.60 to 0.72) have been established between the initial velocity, kinetic energy, specific energy of bullet, and the diameter of the entry wound in 3D modeling, as well as the diameters of the wound channel in its central portion, measured both by conventional measuring tools and based on the results of their 3D modeling (р=0,02). Furthermore, inverse correlation relationships of moderate strength (ranging from -0.63 to -0.66) have been detected between the initial velocity, kinetic energy, specific energy, and the presence of abrasion collar around the entry wound (р=0,03). The created conditions allow to conduct the differentiation in diagnosing the type of projectile, the identification and study of new characteristics of key elements in firearm-related injuries, and improvement in measurement accuracy. They also enhance clarity and objectivity during the execution of forensic medical examinations in cases of combat-related firearm injuries.

“…Suicidal firearm injury resulted in 67,500 deaths worldwide in 2016 that represented 30.5% of firearm deaths [1]. The bullet path in firearm deaths is determined by postmortem radiology and dissection [2]. Generally, the bullet leaves the body through an exit opposite to its entry.…”

Suicidal firearm injuries with bullet embolization following wandering bullet path are infrequent findings where the penetrated bullet could not be detected in the expected location. If this condition exists, one entrance wound will be present without an exit wound. Through necro-radiographs and postmortem autopsy, forensic experts can determine the nonlinear trajectory of the bullet. To understand the internal bullet path properly, forensic experts should interpret the medicolegal investigation results in the context of tissue and ballistics factors. Various medical specialties, including forensic experts, should be aware of the possibility of the nonlinear bullet trajectory and the possibility of bullet embolization in distant sites in order to save lives and/or interpret the collected evidence to support the justice in such uncommon incident.

ZusammenfassungEine retrospektive Auswertung der im Zeitraum von 2009 bis 2018 am Institut für Rechtsmedizin Gießen durchgeführten 5400 Sektionen und Leichenschauen ergab 111 Todesfälle als Folge eines Schusswaffengebrauchs. Diese Fälle wurden hinsichtlich allgemeiner Daten, demografischer Merkmale der Verstorbenen, Schussverletzungen, Todesumstände und -orte, verwendeter Waffen, weiterführender Untersuchungen und etwaiger Täter analysiert.Die Schusstodesfälle verteilten sich auf knapp ein Viertel Homizide, drei Viertel Suizide sowie einen Unfall. Etwa 9 von 10 Schusstoten waren männlich; nahezu drei Viertel der Schusstodesfälle betraf Menschen in der 2. Lebenshälfte. Der häufigste Todesort war sowohl bei Homiziden als auch bei Suiziden das häusliche Umfeld. Ganz überwiegend wiesen die Leichname nur eine einzige Schussverletzung auf; bei den Suiziden lagen nie mehr als 3 Schussverletzungen vor. Die maximale Anzahl von 17 Schussverletzungen fand sich bei 2 Homiziden. Kurzwaffen kamen in zwei Dritteln aller Fälle zum Einsatz, bei den Homiziden deutlich häufiger als bei den Suiziden. Aussagen zum Legalitätsstatus des Waffenbesitzes konnten in etwa zwei Drittel aller Fälle getroffen werden.Aus dem Vergleich mit Datenerhebungen aus rechtsmedizinischen Instituten in Deutschland und anderen Ländern lassen sich teils deutliche regionale Besonderheiten ableiten.
