Typological Approach Features in the Investigation of Serial Sexual Crimes

The article presents the results of testing the typology of serial sexual killers developed by O.D. Sitkovskaya and L.P. Konysheva, on the materials of criminal cases on detected serial crimes of a sexual nature. The study confirmed the presence of the main psychological features specific to each type of criminals, and the possibility of applying the classification for the investigation of other sexual crimes. In addition, mixed types are identified that combine the signs of two and three types of criminal behaviour. Confirming the main hypothesis of the study, the authors of the article consider it necessary to study further the individual psychological characteristics of criminals belonging to mixed types. As a retrospective analysis of the materials of criminal cases has shown and the regular practice of psychological support of the investigation of crimes of a sexual nature confirms, it is the attackers of a mixed type behaviour that are most difficult to identify through the traditional investigative methods.
