The investigation of the deaths of an elderly couple found in a small hotel room that was tightly sealed and heated by an open flame gas heater is presented. Autopsy and toxicologic studies did not reveal a definitive cause of death. Subsequent research and an experiment to duplicate the conditions support the contention that the cause of death was hypoxia due to oxygen depletion by the gas flame.
Embolization is a well-recognized phenomenon in medicine and forensic pathology and generally involves formed blood elements, bone, air, amniotic fluid, or more exotic items such as bullets. We report the embolization of a chain-saw link. The case demonstrates how, without complete autopsy and investigation, a penetrating sharp-force injury could be misdiagnosed and a false conclusion as to the commission of a crime could occur. Although the forensic literature is replete with examples of bizarre emboli, from bullets to suspected crystals of methylmethacrylate, a literature review failed to find a single case of penetrating chain-saw-link injury as a cause of traumatic death. Most reports of chain-saw incidents cite accidental injuries to hands and arms or dramatic facial injuries due to entrapment and recoil (1,2). One fatality occurred from a skull fracture and cerebral injury when a 19-year-old man fell onto a saw.
This paper presents a brief review of the results of research in the area of electrical skin injuries. It also includes a case report of a 5-year-old girl noted on her admission to the hospital to have injuries to the skin of her chest and left arm. Histological examinations demonstrated that the skin lesions were segmental and showed necrosis and inflammation. Deposits of calcium salts distinctly located to collagen fibers were observed below the regenerated epidermis at the periphery of two skin lesions of the chest wall, in the lower part of dermis at the periphery of a skin lesion of the left arm, and within connective tissue adjacent to elastic arteries and peripheral nerves from the thoracic cavity. The pattern of calcification localized to collagen fibers and situated both superficially and deeply in the skin in a zone of viable tissue close to necrotic tissue is characteristic of electrically induced lesions. Although there have been reports of deposition of calcium salts on collagen fibers after application of calcium salts in high concentration at the skin surface, the collagen calcification in the pattern observed in this patient is probably diagnostic of electrical injury.
