criminalization of the timber industry poses a threat to the economic and envi-ronmental security of our state. In the Directive of the Ministry of Internal Af-fairs of the Russian Federation of December 1 , 2010 "On the priority areas of activity of the Department of Internal Affairs and the Ministry of Internal Af-fairs of Russia, the FMS of Russia in 2011" it is noted that the Ministry of In-ternal Affairs of Russia considers as one of the priority areas of activity of the internal affairs bodies the organization of countering shadow processes at for-estry enterprises, the identification and documentation of economic and tax crimes at enterprises and organizations engaged in logging activities. But, as the analysis of practice shows, despite the measures taken, the operational sit-uation at the LPC facilities continues to be difficult. The high market value of timber and timber products, the constant growth of income received as a result of timber smuggling, the possibility of legalization of criminally obtained funds in order to legitimize the possession, use and disposal of these funds, determines the constant criminal interest of a fairly wide range of persons in such illegal activities. One of the conditions for effective counteraction to money laundering and improving the effectiveness of the detection, disclosure and investigation of these crimes is the close interaction of the investigator with the bodies carry-ing out the ORD, the inquiry. Improving the forms of interaction taking into account the specifics of the crime is the need of practice and the task of foren-sic science. Materials and methods: collection, analysis, processing of theoretical and empirical material were carried out on the laws of dialectical materialism using general scientific methods of scientific cognition and empirical research, such as analysis, generalization, systematization, formalization, description, comparison, methods and rules of formal logic, etc., as well as methods of cognition of legal reality, such as: analysis of legislation, analysis criminal cas-es. Results of the study: the conclusions aimed at improving the effective-ness of the interaction of the investigator and the body of inquiry in the identi-fication, disclosure and investigation of cases of laundering of criminal pro-ceeds are formulated. Typical forms are considered, criminalistic recommenda-tions are formulated to improve the efficiency and effectiveness of the interac-tion of the investigator and the bodies carrying out the ORD, the inquiry. Conclusions and conclusions: the specifics of the investigation of cases on the legalization of funds obtained as a result of timber smuggling and predi-cate crimes involve the implementation of a large number of investigative ac-tions and ORMs, which, depending on the current situation of the investiga-tion, are selected by the investigator and represent a program of activities to obtain criminally significant and evidentiary information, in which great im-portance is attached to issues of ensuring close and effective interaction of the investigator and the bodies of inquiry, improvement of the mechanism of its implementation.
