The aim of the study is to examine the possible directions of integration of the sciences of criminology and suicidology in the recognition of suicide. Material and methods: a systematic analysis of the theoretical foundations of suicide detection in forensic science was carried out. Empirical material archives of investigative units, as well as special literature and the media were used. Results: Based on the provisions of the doctrine of forensic recognition, the idea of creating a technology for obtaining criminal-relevant information, that is not available for direct perception, is proposed through the construction of mental models based on trace information detected at the scene of the incident. The practical examples demonstrate the difficulty of determining the subjective side of a suicidal act by using the existing methods of criminal procedural knowledge. A classification of mental models of suicide and tactical combinations for the recognition of suicide are proposed. Inevitable risks and assumptions in building models are marked. Conclusion. The authors have offered the definition of the content of the terms "forensic recognition" and "forensic recognition of suicide"; structure of the theory of forensic recognition; recommendations for a single tactical operation to identify homicides, suicides and accidents.
