Abstract: The subject of the study is the patterns of detection, fixation, preliminary research, the use of criminally significant information and means of processing it in order to identify, disclose, investigate and prevent crimes, as well as the creation of technical means, techniques, recommendations, automated information systems (AIS) optimizing the investigation and disclosure of crimes based on the knowledge of these patterns. The author examines in detail the issue of creating automated crime investigation techniques – a type of information decision support systems. Special attention is paid to the components (databases) of AIS and their content. The author comes to the conclusion that one of its components is the database "Targeting". The functioning of this component and the automated system as a whole should be based on the provisions and laws of forensic science. The methodological basis of the research is represented by the universal dialectical method of scientific cognition, general scientific methods of empirical and theoretical cognition, private scientific methods (formal logical, modeling), as well as special scientific methods (structural criminalistic, etc.). The main conclusions of the study are the definition of the main (basic) structural component of the automated crime investigation methodology - "Targeting". This database should include two blocks: 1) a block of circumstances to be established and proved during the investigation of crimes with the possibility of data entry by the investigator, which will allow specifying these circumstances, taking into account the investigation he is conducting; 2) a block providing the definition of goals in the investigation of non-obvious crimes. At the same time, the system of goals formed according to the crime under investigation is fixed in the AIS as a separate file, with the possibility for the investigator to access its contents and adjust the system of goals taking into account the progress of the investigation. This will make it possible to make a breakthrough in the creation of automated investigation techniques.

Abstract: A high-quality investigation of a crime is impossible without the use of technical means and achievements in the field of information technology. The object of the research of this scientific article is the use of information technologies in the investigation and disclosure of crimes, the subject is the patterns of this activity. The purpose of the scientific article is to determine the directions of the use of information technologies in the investigation of crimes, their characteristics, as well as to establish the reasons that slow down this process and identify priority tasks, the solution of which will eliminate these obstacles. When determining the directions of using information technologies in the investigation, the author was guided by the components (aspects) of crime investigation activities (cognitive, certifying, organizational). It is noted that the process of integrating information technologies into the investigation of crimes is a complex construction of a digital system of criminal justice, which will optimize the activities of the investigator by increasing the efficiency of working with information.
The methodology of the conducted research is determined by its purpose and objectives. It is based on a systematic approach to the study of the use of information technology in the investigation and disclosure of crimes. The research methodology used when writing a scientific article was implemented using the following methods: structural and substantive analysis of scientific papers devoted to the topic of this study; logical (when presenting all the material, formulating conclusions, suggestions and recommendations); comparative legal (criminal procedure legislation, regulatory legal acts) and other research methods.
