“…This case clearly demonstrates that modern imaging techniques are an excellent diagnostic tool in the work of veterinary experts. X-ray images (2,5,6,9,14,22) remain the primary tool for a veterinarian who assesses gunshot wounds. It makes it possible to exclude a gunshot when anatomopathological changes observed during an external visual examination of the animal suggest such an eventuality (17).…”

“…Contemporary technology makes it possible to diagnose cases of animals having being shot even when there are no bullets or pellets in the body or when the animal's body has been destroyed (e.g. burnt); We are able to detect microscopic fragments (residue) of bullets with masses measured in nanograms (3,4,6,15,19,24,27). Despite the possibilities provided by modern imaging diagnostics and residue detection techniques, one must not forget their limitations (7,9,16,21,30).…”

Post-mortem diagnosis of gunshot injuries in an osprey: A case report

The shooting of protected species, especially rare animals, is regarded as a priority issue by law enforcement authorities. In such cases, an expert veterinarian is required not only to confirm the death of the animal as a result of shooting, but also to provide a precise description of the shot. In cases of shootings with pellet bullets, such a description is particularly difficult. The evaluation of the gunshot wounds of an osprey (Pandion haliaetus) delivered to the Veterinary Medical Centre at the University of Poznań called for the use of a variety of diagnostic techniques. A preliminary assessment confirming the shot was based on an X-ray photo. Computed tomography (CT) was used for in-depth diagnostics, providing a spatial representation of bullet stopping points and fragments. The shot caused a lower leg bone fracture. This damage upset the anatomical structure of the animal's limb, which made it impossible to establish the wound channel by CT. Therefore, full shot characteristics could only be made only after a classical post-mortem examination. This examination facilitated the use of modern imaging diagnostic techniques. The use of mixed diagnostic techniques enabled us to determine the number of shots, the type of ammunition used and the direction from which the shot was fired. On the one hand, this case illustrates the possibilities offered by modern imaging diagnostic techniques and, on the other hand, it shows that the classic post-mortem examination remains a primary diagnostic tool for veterinary forensic experts. This is especially important when preparing forensic veterinary opinions in high-priority law enforcement cases. .

“…The occurrence of environmental particles similar in composition to GSR has been reported in the literature. Particles similar in shape, size, and elemental profile have been identified in brake linings and their wear products , firework particles , and welding fume particles (please note: none of the particles presented in are consistent with Modern Western ammunition types, unless heavy metal free). Environmental and occupational origins need to be considered when interpreting the significance of GSR particle detection, particularly when only small populations are found.…”

A review of the literature concerning the fate and behavior of gunshot residue (GSR) is presented. A number of concomitant parameters including firearm and ammunition type, plume and GSR material characteristics, travel distances, chemical composition and GSR morphology are critically discussed in relation to their effects on the distribution and deposition, transfer and persistence processes of GSR. The underlying mechanisms associated with such processes are also considered. Knowledge of these processes on GSR materials could provide valuable information concerning scene preservation and subsequent forensic sampling. The number of GSR particles deposited can vary significantly with each firearm discharge, highlighting the potential to produce distinctive data in each individual case. With the continual development and compositional changes of new ammunition types, further evaluation of the effect these processes may have on GSR evidence and their possible influence on the interpretation of the analytical results should be given due consideration.

“…Few researches have indicated the chances of having GSR-like objects, in cases which are not linked to criminal offenses, this leads to a number of false positives. Instances of which include car brake pad particles, vehicle hybrid airbags, fireworks, and particles from the welding process (Bueno and Lednev 2014;Abrego et al 2012;Taudte et al 2014;Brozek-Mucha 2015).…”

Background This review represents many significant methods of chemometrics applied as data assessment methods originated by many hyphenated analytical techniques containing their application since its origin to today. Main body of the abstract The study has been divided into many parts, which contain many multivariate regression methods. The main aim of this study is to investigate the chemometrics tools used in GSR (gunshot residue) or forensic ballistics. Short conclusion As a final point, the end of part of this review deals with the applicability of chemometric methods in forensic ballistics. We select to give an elaborate description of many significant tools established with their algorithm in admire of utilizing and accepting them by researchers not very aware with chemometrics.
