| Summary: | <pre><strong>Introduction and purpose. </strong>Electroshock devices are a type of </pre><pre>non-lethal weapon and are widely used. The systematized data </pre><pre>concerning the forensic medical assessment of injuries caused by </pre><pre>electric shock devices are extremely limited. The purpose of the </pre><pre>study was to increase the efficiency of forensic assessment of </pre><pre>injuries caused by electroshock devices by using the methods of </pre><pre>elemental analysis, namely, X-ray fluorescence spectral analysis. </pre><pre><strong>Methods.</strong> During the experiment, the electric discharges were </pre><pre>applied to the skin flaps using electric shock devices under two </pre><pre>conditions, namely, in close contact of the ESD electrodes with </pre><pre>the skin and from a distance of 3-5 mm. A macroscopic study of </pre><pre>skin changes obtained due to the electric impact of electric shock </pre><pre>devices was carried out, as well as X-ray fluorescence spectral </pre><pre>analysis to establish qualitative and quantitative indicators of the </pre><pre>chemical elemental composition of the studied objects. </pre><pre><strong>Results.</strong> It was found that under the condition of causing damage </pre><pre>from a distance the formation of macroscopically visible changes </pre><pre>resembling the typical electric burn was observed. No increase in </pre><pre>the concentration of chemical elements (metals) is determined in </pre><pre>all samples of biological material after the impact of electric </pre><pre>discharges of ESD in this condition. Under the condition of close </pre><pre>contact of the electrodes of electric shock devices with the surface </pre><pre>of the skin no macroscopically distinguishable lesions were found </pre><pre>on the skin. The XRF spectral analysis revealed metal deposits in </pre><pre>the areas of skin flaps that were subject to ESD. </pre><pre><strong>Conclusion. </strong>The XRF spectral analysis can be useful tool for </pre><pre>objective confirmation of the action of electroshock devices.</pre> |
