The diagnosis of death as a result of starvation is established on anthropological measurements, visual appearance of the deceased on external and internal examination, microscopic analysis, laboratory testing, and exclusion of other causes of death. Herein, we present our findings on a case of 95‐year‐old man who died of starvation. After the diagnosis of starvation was established by traditional forensic medicine methods, we have conducted retrospective segmental analysis of stable carbon (δ13C) and nitrogen (δ15N) isotope ratios in hair sample. This method reveals periods of starvation through decrease in δ13C and increase in δ15N along the strand of hair. Our analysis revealed the decrease of 0.6 ‰ in δ13C during the last 10–12 weeks prior to death, similar as reported in other investigations. Also, a decrease of 0.7 ‰ in δ15N during the last 8–10 weeks prior to death was determined that was different than observed in previous studies. 相似文献

Although certain air weapons attain muzzle velocities comparable to some firearms, their successful use for committing suicide is rarely seen. Herein, we report a case of a young female died shortly after urgent admission to the hospital with penetrating gunshot wound to the chest. The autopsy revealed perforation of the pericardium and two perforative defects to the right heart ventricle. Injury was inflicted by a 0.177 caliber pellet, fired from an air rifle found near her body. Investigation ruled the death as suicide. The used air rifle fired the pellet with the energy density of 1.9 J/mm2, substantially above the threshold for inflicting injury. The pellet penetrated through two layers of cotton fabric and several layers of tissue to inflict fatal injury to the heart. In addition, we provide an insight into the wounding potential of air weapons, which illustrates the need for greater caution in handling those devices. 相似文献
