Burns in forensic against

Burns are usually the result of an accident; murder (obvalivanie children, burning using flammable liquids of people are in an unconscious state, and others) and suicide (immolation) are rare. Possible cases of burning of dead bodies or their parts with the purpose of concealment of the crime.
In most cases death from the burn begins on the first day of shock, and during the autopsy find only signs of sudden death. Upon the occurrence of death within a few days after O. find a plethora and swelling the brain and lungs, multiple bleeding and thrombosis in the gastrointestinal tract, sometimes in the kidney, adrenal, dystrophic changes in the parenchymal organs and nerve cells of different departments of the Central nervous system. Described education of acute ulcers stomach and duodenal ulcer. Renal tubules scored haemoglobin cylinders. Local changes on the corpses largely depend on the origin of burns, their extent and the time elapsed from the moment Acting to death.
In case of prolonged exposure to the corpse of a high temperature is charring: upper and lower limbs due to thermal energies, increasing muscle flexed in the joints (the corpse adopts the posture of the boxer"), leather seats bursts, the skin can burn up your muscles and bones, joints shall be opened, the bones become fragile and break easily. Such posthumous skin tears and broken bones are sometimes taken for a lifetime. Can violate the integrity of the skull and formed an epidural hematoma, which sometimes leads to erroneous conclusions about the lifetime of damage to the skull; the internal organs and skeletal muscles become like a scalded, light clay shade.
It is often necessary to solve the question about lifetime or after death origin burn. On prizhiznennoi O. indicate the evidence on blinking eyes when exposed to high temperatures: light (unfinished) folds of skin around the eyes and forehead, undamaged eyeballs and conjunctiva; the presence of soot in the respiratory tract, down to the smallest of the distal Airways; changes in the elastic frame bronchi (with lifetime inhalation of hot air); the presence of carboxyhemoglobin in the blood; the presence of skin bubbles containing exudate and leukocytes; locations scabs network of blood vessels, filled with coagulated blood, and hemorrhages in strings.
Investigation of the corpses of persons exposed to high temperature, should be started with inspection service or its residues. When inspecting the corpse should pay attention to the location of the burns, which may indicate the mechanism of their origin (for example, the direction drips under the action of hot liquids, etc.,). On the surface burned areas can be detected particles of a substance causing the Acting, or the products of its combustion. In the case of charring of the corpse there is a need to identify. For this purpose, use of preserved bones (especially teeth), parts of clothing, shoes and others (see identity). Be sure to conduct additional research: histological, bacteriological (at death from infection), spectral analysis of blood on the carboxyhemoglobin, forensic chemistry (for chemical burns). Non-fatal burns and their consequences (extensive scarring, restricting movement, and others) are qualified in accordance with the rules determining the severity of the bodily injury.
