Abstract

|
Because an electrical burn is lack in some of the electrocution, informations gathering from the death circumstances and witnesses are of great importance in the investigation of the electrocution death.
An electrical burn occurs ordinarily in th3 contact area of the skin to the electrode. exhibiting punched-out or crater-like lesion with central carbonization. Histologically denaturation of collagen fibers in the dermis due to heat results in pale blue stainability in H-E staining in addition to multiple blister formation in the epidermis, microblisters in the epidermal squamous cells and the characteristic palisading pattern of epidermal nuclei.
The location of the electrical burn should be ascertained in order to determine the fatal electrical circuit.
An electrical burn without carbonization should be differentiated from a heat burn and a contusion. Because of lack of palisading appearance of the epidermal nuclei in the heat burn it can be easily differentiated. Usually the color of the contusion is deep blue-red in contrast to the bright red color of the electrical burn, and the margin of the contusion is less obvious than that of the electrical burn.
Investigation of Death Due to Fall
In relation to the height and circumstances, the following situations encompassed are in the category of falling; a fall in the plain, a fall from the considerable height without intervention during the fall, a fall from considerable height with intervention during the fall like a fall from stairs, and diving in shallow water.
The major cause of death in the fall from the plain is the head injuries. Therefore, in the investigation of the falling death, painstaking attention should be paid to search an injury or injuries of scalp, skull, meninges, and brain.
In the falling death from considerable height, injuries are usually demons ratable in the contact parts of bodies to the plain and to other substances during fall as well as in the organs or tissues bearing the falling force. So every injury is to be ascertained in order to reconstruct the falling situation.
The major injuries of diving death in the shallow water is cervical fracture or dislocation.
