Signs of stay of the corpse in the water

Rapid cooling of the body. In the water, especially cold, the body temperature of a corpse is reduced significantly faster than stay in the air, and depends on the water temperature. Time of stay of a corpse in the water and the prescription of death on the temperature reduction is difficult to determine, because the patterns are not installed.
Pale skin. When released into the water with a temperature below the temperature of the body of dead body skin vessels contract, which is what causes the pale skin. At the same time there is a reduction of muscles, straightening hair, which leads to the emergence of so-called goose skin. This also reduces the scrotal skin and the skin of the breast. These symptoms may occur when drowning in cold water and penetration of a corpse in the water soon after the time of death.
Grey shade of purple cadaveric spots is determined by the number emulsionnoj blood.
The pink color of the skin around the edges of corpse spots occurs because under the influence of water epidermis is loosened, that facilitates the penetration of oxygen, which oxidize hemoglobin.
Maceration. Within a few hours after a stay of a corpse in the water is celebrated pearl-white color of the face, the Palmar surface of the hands and the plantar surface of the foot. Within 1-3 days wrinkled skin all the palm of the hand cleaners" (Fig. 13), and in 5-6 days - stop.

By the end of the week begins Department of the epidermis, and by the end of the 3rd week swollen, loose and wrinkled epidermis can be removed as gloves (hence the name "gloves of death"). A certain influence on the dynamics of maceration also provides the mineral composition of the water environment (fresh, salty, sea). Clothing on the body, gloves on his hands and shoes delays the development of maceration.
In practice (at the decision of a question on stay of a corpse in the water taking into account growth in the process of maceration) you can use the data in the table. 4.

In the water develops the rotting corpses with the formation of putrid gas emissions, under the influence of which the corpse might pop up, even if it was bound cargo weighing up to 30 kg
Due to the loosening of the skin (about two weeks) hair loss begins and by the end of the month, especially in warm water, there may be full "alopecia". At that, unlike lifetime hair loss on the scalp of a corpse well defined wells from the lost hair. The possibility of hair loss for long stays of a corpse in the water must be considered when there is a need to identify the corpse.
It should be borne in mind that the water may be placed in the body of a man after inflicting deadly mechanical damage to conceal the crime. The corpse is usually clearly visible injuries from blunt or sharp objects, firearms, poisoning of some poisons and other
The main issue is detected on the corpse mechanical damage is the establishment of their origin (lifetime, posthumous). Corruption in the water lifetime of origin in the form of abrasions, contused wounds, injuries to the bones of the code and the base of the skull can occur when jumping into the water from impacts on the rocks, piles and other items. Damage in the form of compression fractures of the cervical vertebrae usually occur when jumping into the water upside down in shallow water. Therefore, in all cases of drowning need to make control cuts back of the neck for the study of soft tissues and vertebrae. The body of the person in the water can be exposed during the life of the action of propeller screws and underwater wings of river and sea vessels and other
Posthumous damage can be caused poles, poles, and other objects used for the detection of a corpse in the water. In the study of the corpse can be found injuries in the chest, abdomen and limbs, as well as fractures of the ribs, arising from the carrying out of artificial breath.
The corpses floating in the water, can cause various damages animals, inhabiting reservoirs: raki, water rats, sea rays, crabs and other types of damage caused leeches, forming multiple T-shaped surface wounds on the skin of a corpse.
Some species of algae can settle on the corpse. The development cycle of these algae using forensic Botanical expertise you can install the sample period of stay of a corpse in a specific area of the water body.
When examining the dead at the scene (after removing the corpse from the reservoir) draws attention to the presence of foam around his mouth and nose, maceration of the skin, marked damage that may occur in vivo or posthumously and be of different origin, including in the provision of first aid at artificial respiration (bruises on the arms, sadnenia on anterolateral surfaces of the chest). Along with the corpse to the morgue send a sample of water from a reservoir from which you extracted the corpse (not less than 1 l) for further identification of plankton to compare it with plankton, which may be discovered during examination of a corpse in the morgue. There are objects that hold the body on the water surface (life belts and others) or, on the contrary, immersive (stones, objects bound to the body or in a pocket). Describes the state of the service, the presence of particles of sand or algae.
At movement of a corpse in flowing waters, especially in the mountain rivers, on the body can be detected signs of starosti for shoes, clothing, skin, nails, and even on the bones of the skeleton. Depending on the topography and features a bottom (sharp stones, snags, and other) when you move the corpse over water it can be mechanically removed clothing and body caused significant damage, even to dismemberment.
