kriminalisticheskie TRASSOLOGIYA
- Forensic doctrine of a certain group of tracks.
Studied KT should be distinguished from other signs that show the outward signs they have left things. In the formation of the object involves two tracks, one of which
- Sledoobrazuyuschy object and another -sledovosprinimayuschy.
External signs sledoobrazuyuschih objects:
1) The shape and size of the object as a whole;
2) the shape and magnitude of the individual elements of the contact surface.
They are displayed in the following in a modified form. Depending on the quantity and quality of display signs sledoobrazuyuschy object can be attributed to a particular class, genus or species.
KT is developing scientific and technological means and methods of detection, capture and trace-study maps for the purpose of
sledoobrazovaniya determination mechanism. Scientific classification should be carried out by dividing them into several types for logical reasons:
1) the type of energy impact on sledovosprinimayuschy object;
2) localization of the footprint on the surface sledovospri- Nima object;
3) the degree of deformation sledovosprinimayuschego object;
4) direction of movement of the object relative sledoobrazuyuschego sledovosprinimayuschego.
The traces can be formed by mechanical changes under the influence of heat, resulting
recovery or oxidation processes. By the form traces of the impact of energy are divided into mechanical, thermal and chemical effects.
According to the impact zone are divided into the following local and peripheral effects. As a result, deformation sledovosprinimayuschey surface can form two kinds of tracks. If the hardness exceeds the hardness of the object sledoobrazuyuschego sledovosprinimayuschego, formed the bulk tracks.
track formation occurs under
the impact of countervailing forces. When sledoobrazuyuschy object affects sledovosprinimayuschuyu surface without lateral displacement, the contact is static. In this form static tracks. If the subject moves sledoobrazuyuschy
relatively sledovosprinimayuschey
surface formed dynamic traces.
In forensic practice should be subdivided:
1) to fingerprints;
2) footprints;
3) Evidence of hacking tools and instruments;
4) the following means of transport and so on.
