Review: Cattle-napping is a widespread phenomenon in some regions of Russia. Taking this fact into account, the authors of the article study the tactical aspects of criminal intelligence and investigative operations aimed at detecting and investigating the above mentioned criminal infringements. The aim of the research is to develop a set of recommendations for more effective realization of tactical operation “Plea deal” in criminal cases of cattle-napping. The research methodology is based on general and specific research methods, including analysis, synthesis, induction, modeling, the systems method and specific methods of forensics. Plea deals as a procedural institution (chapter 40.1 of the Criminal Code of Russia), aimed at raising effectiveness of fighting organized crime, are used also in criminal cases of cattle-napping. At the same time, the analysis of practical activities and special scientific and methodological works allows the authors to state that up to the present day, no scientifically grounded forensic recommendations for organization and realization of a tactical operation “Plea deal” for such cases have been developed. The article describes the essence and the content of such an operation, and the stages of its realization. The authors formulate recommendations for the optimization of investigation of organized cattle-napping.
