The article describes the methodological aspects of the expert investigation of traces of trasological origin in the part of the peculiarities of solving identified problems during the direct investigation of traceable and trace-forming objects. The advantages of the investigation of the volume copies of the bottom of shoes in the laboratory conditions that are made by using a reusable substance “MikroTrack ™” are described.
The aim of the article was to show how the high quality comparative material allows an expert to get the additional forensic information, to get the data about the conditions of formation of traces at the crime scene, obtain the information about the features that the shoes had left. Experimental copies that are made of the tested shoes have many advantages comparing them with the shoes themselves. When investigating a trace-forming object (shoes) that is in the same position and condition, it is difficult to see all the features (detect the sustainable complex of individual features) that it can leave on the trace-forming surface.
The article in details describes the advantages of obtaining samples for the comparative study on reusable substances in the laboratory conditions over other surfaces (sand and soil). The practical usage of the reusable substances allows using the sustainable complex of individual features in the comparative study effectively.
Key words: trace and trace object, complex of individual features, experimental copy, reusable substance, morphological features of the bottom of the shoe.
