Tactical Aspects of Using Odor-Based Biodetection to Raise the Informational Value of the Drug Trafficking Investigation Process

Purpose: based on the analysis of the current state of the use of such bio-detectors as search dogs in the police department, to establish the need to develop tactical solutions aimed at fixing the facts of the signaling behavior of search dogs during investigative actions (searches) on crimes in the field of drug trafficking to increase the information content of the investigation process. Methodology: the methodological basis of the work is presented by such methods as description, analysis, historical method, comparative legal analysis. Conclusion: fixing the fact of detecting odorous traces of narcotic drugs and psychotropic substances that remain in places where narcotic drugs and psychotropic substances were stored by criminals earlier, but were moved, for subsequent use in the investigation when establishing "virtual" episodes of criminal activity. Scientific and practical significance: improvement of tactical techniques, procedural consolidation of "virtual" episodes, providing for the fixation and detailed description in the protocol of the investigative action of information about places where narcotic drugs could previously be in order to increase the information content of the investigation process of crimes in the field of drug trafficking. The fixation of these circumstances in conjunction with other sources of information will allow to objectify information about the duration and scope of criminal activity of the organized criminal group (C).
