The research article considers that the investigation of the scene is one of the most important and primary investigative actions, which begins the entire course of the investigation of a criminal offense, and the quality of which directly affects the effectiveness of the solving and investigation of the crime.
The analysis of understanding of the concept of “forensically significant information” by individual scientists, as well as its types and sources is carried out.
Attention is focused on the fact that a successful examination of the place of a criminal offense depends on the correct preparation of the investigator for its conduct. The analysis of scientific sources allows us to state that along with a fairly complete consideration of the issues in terms of the organizational and tactical aspects of the inspection of the scene of a criminal offense, there is a certain gap regarding the protection of the scene. This issue is of an unconditional practical significance and relevance, in particular for avoiding damage and destruction of material objects associated with the circumstances of the crime.
Therefore, the purpose of this paper is to highlight the results of the study and development work carried out by the State Research Institute of the Ministry of Internal Affairs of Ukraine to create several prototypes of a mobile tent and a special set of protective screens to ensure the safety of forensically significant information during investigative (search) activities.
Analysis of the tactical and technical characteristics of protective equipment of both domestic and foreign production showed that they are very different. There are the tents that are very simple to manufacture and operate; in particular, they do not even have side walls. In turn, there are multifunctional and complex tents, which make it possible to preserve 98% of natural light, provide conditions for research, including the identification of various traces using cyanoacrylate, and even shield the action of wireless communication devices (smartphones, tablets, devices GPS, etc.).
The created samples of protective equipment were the result of a search for optimal characteristics, in particular, the properties of the fabric cover and frame materials. Based on the analysis of the samples of tents and protective screens existing in domestic and foreign markets, as well as the requirements to the forensic support department of the Main Investigation Department of the National Police of Ukraine, including number to its mobility.
Key words: forensically significant information, criminal offense, protection of trace information, special means and devices, tent, protective screen.
