“…It has been proven that the type of tissue is one of the factors that affects the features of the formation of the soot pattern around the incoming gunshot damage, and in general affects the deposition of additional factors of the shot, forming specific characteristics, even allowing to identify the type of firearm that was used [4,18,26].…”

Annotation. The spread of non-lethal firearms among different sections of the population of Ukraine and the increase of their varieties available for sale is another modern challenge for forensic examination. In this regard, there is an urgent need to study the characteristics of injuries caused by the newest types of traumatic guns, taking into account such a factor as clothing. The purpose of the study was to determine the features of the shape and size of damage defects caused by shots from “Fort 12R” and “AE 790G1” pistols from different distances depending on the covering material of the human body simulator. To achieve the goal, 120 gelatin blocks (60 for each gun) were shot, divided into 4 subgroups according to the coating: bare blocks, covered with cotton fabric, denim fabric, leatherette. Shots were fired from contact range, 25 and 50 cm. Subsequently, damage description and statistical processing of the obtained results were carried out in the licensed statistical package “Statistica 6.0”. When analyzing the reliability of differences between the studied groups in the assessment of the area of the defect, mostly significant differences (p<0.05-0.01) were found both between different subgroups of blocks and between the corresponding groups of guns. Analysis of the defect shape indicator revealed both significant differences (p<0.05-0.01) and trends to differences (p<0.076) in all studied groups, except within the subgroup where bare blocks were used. Thus, the identified differences in the shape and area of defects allow us to use them to solve the issue of identification of shots from “Fort 12R” and “AE 790G1” pistols at close range, 25 and 50 cm distances and help to improve the understanding of the role of clothing in gunshot injuries. In further research, it is advisable to perform a comparative analysis using data on additional factors of the shot.

Purpose The aim of this systematic review was to provide a comprehensive overview of micro-CT current applications in forensic pathology, anthropology, odontology, and neonatology. Methods A bibliographic research on the electronic databases Pubmed and Scopus was conducted in the time frame 01/01/2001–31/12/2021 without any language restrictions and applying the following free-text search strategy: “(micro-computed tomography OR micro-CT) AND (forensic OR legal)”. The following inclusion criteria were used: (A) English language; (B) Application of micro-CT to biological and/or non-biological materials to address at least one forensic issue (e.g., age estimation, identification of post-mortem interval). The papers selected by three independent investigators have been then classified according to the investigated materials. Results The bibliographic search provided 651 records, duplicates excluded. After screening for title and/or abstracts, according to criteria A and B, 157 full-text papers were evaluated for eligibility. Ninety-three papers, mostly (64) published between 2017 and 2021, were included; considering that two papers investigated several materials, an overall amount of 99 classifiable items was counted when referring to the materials investigated. It emerged that bones and cartilages (54.55%), followed by teeth (13.13%), were the most frequently analyzed materials. Moreover, micro-CT allowed the collection of structural, qualitative and/or quantitative information also for soft tissues, fetuses, insects, and foreign materials. Conclusion Forensic applications of micro-CT progressively increased in the last 5 years with very promising results. According to this evidence, we might expect in the near future a shift of its use from research purposes to clinical forensic cases.
