“…Despite the possibilities provided by modern imaging diagnostics and residue detection techniques, one must not forget their limitations (7,9,16,21,30). When investigating cases of animals shot with small arms, experimental testing and gunshot models may also be used, but these tests and models should be used with caution, as they are unable to reproduce actual shots (13,18,25,28).…”

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 type of ammunition, previously detailed, has the greatest influence on the cavity formed, but the varying ability or tendency of the projectile to fragment or to partially or completely flatten (mushroom) on impact, in combination with the caliber of the projectile and the presence and design of an outer jacket, also significantly affects wound capacity. 2,6 While the shape of the frontal surface of a projectile largely determines the size of the cavity, current measurement techniques are too variable to allow postmortem caliber derivation. 4 Advances in the use and evaluation of computed tomography to characterize cavity dimensions have the potential to improve measurement accuracy such that cavity dimension measurement may contribute data useful for weapon and projectile identification in the future.…”

Projectile injury represents an estimated 14% of reported animal cruelty cases in the United States. Cases involving projectiles are complicated by gross similarities to other common types of injury, including bite wounds and motor vehicle injuries, by weapons and ammunition not commonly recognized or understood by veterinary medical professionals, and by required expertise beyond that employed in routine postmortem examination. This review describes the common types of projectile injuries encountered within the United States, as well as firearms and ammunition associated with this form of injury. The 3 stages of ballistics-internal, external, and terminal-and wounding capacity are discussed. A general understanding of firearms, ammunition, and ballistics is necessary before pursuing forensic projectile cases. The forensic necropsy is described, including gunshot wound examination, projectile trajectories, different imaging procedures, collection and storage of projectile evidence, and potential advanced techniques for gunpowder analysis. This review presents aspects of projectile injury investigation that must be considered in tandem with standard postmortem practices and procedures to ensure reliable conclusions are reached for medicolegal as well as diagnostic purposes.

“…Bodily tissue is impelled outward from the axis of the bullet causing a temporary cavity in elastic tissue that may, if stretched beyond the elastic properties of the tissue, be an additive factor to the permanent wound cavity (Felsmann et al ). The greater the bullet velocity, the further the tissue will move away from the bullet.…”

Wound ballistics is a science that has been gaining attention in wildlife management because of the movement toward non-lead bullets for hunting and wildlife management projects. Wildlife biologists and managers are interested in evaluating new bullet technologies and using traditional bullets outside of their initial design parameters; however, much of the background and science that is involved in a wound ballistic study is outside of a typical wildlife biologist's training. I present a review of major wound ballistic history and background, including theories of how bullets wound and kill, and I review the primary techniques used for wound ballistic research. I found that most of the wound ballistic literature is found in a wide range of publications in both gray and primary literature; however, little work has been published that uses these techniques to investigate wound ballistics for wildlife management. Many of the techniques described for assessing the terminal ballistic for medical, military, and law enforcement purposes can be applied in the wildlife management field. Ó
