Description

one

The invention relates to forensic medicine and forensic science, can be used to identify the identity of corpses that do not have a horny layer of skin on their fingers.

A known method of obtaining a fingerprint imprint on a corpse by imprinting it on a glass slide, followed by photographing {ji.

However, the known method does not allow to obtain a print from macerated corpses without a stratum corneum.

The purpose of the invention is to obtain an imprint of macerated corpses devoid of the stratum corneum.

This goal is achieved by the fact that, according to the method of obtaining a fingerprint imprint on a corpse by applying an imprint to a glass slide, and then photographing it, the print is applied to a glass slide previously treated with ammonium chloride vapor.

The method is carried out as follows; at once.

First, the hands of the corpse are separated from the forearms at the level of the radiocarpals joints, and they are placed in running water for 2 hours to remove foreign inclusions and stratifications (sand, or filaments, dead cells of the stratum corneum, etc.). Then each finger is stamped with a pencil, stitching a square of ordinary photographic paper with dimensions of 11 cm with numbers from 1 to 10 on it. After that, the mark + 1 fingers are placed in running water again

"5 to remove foreign particles, and the finger pads are dried with a gauze pad. Then prepare the slides by applying a layer of ammonium chloride on them.

20 The number of glasses prepared depending on the number of fingers. After applying a layer of ammonium chloride on the slides, fingerprints are produced and then photographed. PRI me R. Police officers raised the body of an unknown man with signs of violent death in a state of deep-seated rotten changes, with the horny layer of skin completely torn off, as a result of which any of the previously known methods could not be fingerprinted. By the forensic expert, the hands are separated from the corpse of an unknown at the level of the radiocarpal articulations for possible restoration of the finger pattern and obtaining high-quality fingerprinting. The hands of the right and left hand of a person received for examination are devoid of the stratum corneum of the skin, covered with an insignificant layer of silt. To remove the sludge, the hands are placed in cold running water for 12 hours. After that, the hands are dried with a gauze pad and the fingers are separated from the hands at the level of the phalangeal joints and marked from 1 to 10 (marking is done by stitching small fingers to the skin of each finger). square a photo of a paper with a serial number, putting fingers on marked paper, etc.). The pad of each finger is carefully drained with a gauze pad. In order to obtain a fingerprint print, take 10 glass slides, one of the surfaces of which is fumigated with ammonium chloride vapors. To obtain vapors, dry ammonium chloride powder is placed in a glass pipette with a diameter of at least mm and with an extended end up to 20-30 mm long. The transition point to the constricting part is heated over the flame of the alcohol burner until white smoke appears from the narrow end of the pipette. With the appearance of smoke, the wide end of the pipette is brought to the researcher's mouth and exhaled air is slowly and evenly blown into the pipette, thereby increasing the output from the pipette ammonium chloride vapors, which are evenly thin layers applied to a glass slide at an angle of 5 to the ammonium chloride vapor stream. The process of applying a layer of ammonium chloride is carried out for 1 minute depending on the state of the pattern of the actual skin layer of the person. The process of making an imprint on the glass surface with ammonium chloride is carried out by selecting the thickness of the ammonium chloride layer from barely noticeable to more concentrated to obtain a clear image of the finger pattern. In this case, for each finger, it is carried out within 3 times the repeated removal of a layer of ammonium chloride from the glasses with a gauze pad, washing off the layer from the pad of the finger with water and drying it. The resulting prints are photographed in the usual way. After all the operations, the identity of the corpse found in the well was established. The proposed method allows to obtain a fingerprint of a fingerprint from macerated corpses devoid of the stratum corneum and to identify individuals. The method of obtaining a fingerprint imprint on a corpse by imprinting it on a glass slide and then photographing it, in order to obtain an imprint from macerated corpses devoid of the stratum corneum, the impression is applied to an object glass pretreated with ammonium chloride vapor.
