Peculiarities of identification of the corpses of unknown persons

Important for identification of a person are also features of the external structure of the head and face, described by a forensic medical expert system of verbal portrait and fixed with the help of photography. For the purposes of identification of the unknown deceased person it is advisable to make a plaster mask of a face. It is recommended to pay attention to facial asymmetry, since most people have one half of the face is slightly narrower and higher, and another wider and less in height, therefore distinguish between "left" and "right" types skull asymmetry.
Among private physical signs of great importance is the condition of the teeth and jaws, because it sufficiently individually and, importantly, is investigated in detail and recorded in the medical documents in a person's life. It is necessary to investigate and fix the following characteristics: 1) features of joining the teeth, determining the type of the bite; the number of teeth, missing teeth and the condition of the wells or the free edge of the jaw in place of a missing tooth; the size of the teeth; dental overlay; 4) pathological changes (localization and depth of caries and other); traces of treatment (fillings, the material from which they are made). If there dentures celebrate its type (removable and non-removable), the location, the design and the material from which it is made. In the study of the corpses of unknown persons recommended radiography jaws, removal of prosthetic devices for further research, as well as the manufacture of schematic drawings of dental rows and pictures of the teeth.
A comparative study for establishing the identity of the deceased or missing person produces, as a rule, a forensic expert with the research assistance of two groups of criteria : 1) installed in the forensic medical study of the corpse of the unknown man; 2) characterize the missing person. These features reveal investigative bodies (on the basis of the descriptions, medical documents, films, photos and other) and provide the expert.
You can select a comparative study produced by x-ray, photos, data, medical records, and other materials.
A comparative study on radiographs are of great importance. It is known that the bones are many signs that a significant portion of which depends on age, sex, profession, lifestyle, diseases, traumas, i.e. have individual character. Some of these signs appear on x-rays.
The study started with a separate study x-rays produced during the life of the missing person: determine the part of the body, displayed on the radiograph, the projection direction (right or left). Then produce x-rays of the relevant part of the body of the unknown person (possibly the same projection, with the same distance, and with the same rigidity of x-rays). Then carry out a comparative study either directly on the box, or photo prints obtained with x-rays.
The comparison is made on the external contours, shape and size of bones and bone formations, the nature of the structure is compact and cancellous bone, post-traumatic and pathological changes in bone tissue.
A comparative study on the photos is also important to identify the victim. Use photos of the head (s)made upon human life, and pictures of the head (s) of the corpse of the unknown. A necessary condition is the manufacture of post-mortem photos in the same scale and the same foreshortening, which made photos. The comparison is produced by the method of verbal portrait: is a description find the photos of the signs of the appearance, and then compare them with each other.
As a method of identification of the subject of the use fotocamera - mapping photos skull corpses and missing people. It is in combination (single photo) images of the head and skull with markup certain points (benchmarks) in the skull and pictures. Comparison of conformity of the skull and pictures of the head produced by coincidence (or mismatch) targets, paths of soft tissues and bones, the thickness of the soft tissues in the mouth (Fig. 101).fotocamera identification by skull
