“…4), one will find residue deposits in the surrounding folded tissue. Depending on the ammunition used, there will also be thermal damage in the path of the projectile through the tissue due to the gas temperature [5,7]. With relative close-range shots one will, as expected find deposits of the scattered tip (Fig.…”

The histological staining technique using rhodizonate is also effective for the determination of the firing distance by examining the distribution and intensity of the staining reaction. The differentiation between absolute close-range shots and long-range shots is generally possible without any doubt. The method is not recommended for routine examinations but it is very useful for cases lacking the possibility to investigate smoke and powder deposits in a criminalistic manner, i.e. surgical skin biopsies of hospitalised victims and skin highly altered by the effects of fire, water or by post-mortem decomposition.

“…This component would result in the creation and subsequent expansion of gaseous material within the wound cavity. Heat from a bullet is generally considered to have little effect in ballistic wounding (24,26), with “bullet burns” instead thought to be owing to gas of combustion from the firearm, but further research is needed to clarify whether the thermal component has a role in wounding.…”

: Gunshot backspatter comprises biological material expelled backward through bullet entry holes. Crime scene investigators analyze backspatter patterns to infer wounding circumstances. An understanding of the mechanism of backspatter generation, and the relationship between spatter patterns and bullet and tissue characteristics, would enhance the predictive value of such analysis. We examined soft‐tissue ballistic wounding responses to determine the underlying components and how these might be relevant to the generation of backspatter. We identified five mechanistic components to ballistic wounding (elastic, viscous, crushing, cutting, and thermal), each related to mechanical disciplines (respectively, solid mechanics, fluid mechanics, fracture mechanics, rheology, and thermodynamics). We identified potential roles for these five components in backspatter formation and provide a scenario whereby a sequence of events incorporating these components could lead to backspatter generation and expulsion. This research provides a framework for the mathematical representation, and subsequent computational predictive modeling, of backspatter generation and pattern formation.

“…Exsiccation of the tissue deposits may increase the adhesive forces to the jacket and also represents favourable conditions for the conservation of DNA. Exsiccation is caused by the hot surface of the bullet, which is thought to briefly reach temperatures of approximately 100-200°C (Sellier 1982;Marty et al 1994).…”

STR-based individualisation of biological deposits on bullets after perforation of tissue, can identify the person injured or killed by a particular bullet and comparison with the firearms used can identify the weapon and thus possibly the person who did the shooting. In this study, the effect of subsequent impacts on intermediate targets such as loss of cells was investigated by amplification of mitochondrial (mt) DNA. Bovine tissue was perforated and the 9 mm Luger FMJ bullets were recovered from the bullet collector. The mt cytochrome-b (cyt-b) gene could be amplified by the polymerase chain reaction (PCR) from 14 out of 15 bullets. Examination with a scanning electron microscope (SEM) and an energy-dispersive X-ray spectrometer (EDS) demonstrated the presence of minute dried tissue deposits on all bullets (n = 10) but was not able to establish preferential locations. In a series of 25 gunshots, various intermediate targets (glass, wood, car metal, gypsum board, asphalt) were perforated/impacted following perforation of tissue and the cyt-b gene could be typed from all bullets. It is concluded that subsequent impacts on intermediate targets do not eliminate enough biological deposits to render DNA analysis impossible and that the amplification of mtDNA is a useful additional method.
