Abstract

Based on the discussion of environmental criminology, this study aims to identify the distance criminals journey to commit crimes. Verifying how much a criminal moves to commit a crime has the advantage of predicting the distance and helping the police investigation. According to the results of the study, sex crimes showed the highest density within 2km of the criminal's residence, and after that, they gradually decreased. As a result of OLS regression analysis, it was confirmed that the distance of movement of a crime varies not only according to the characteristics of the criminal but also according to modus operandi such as the relationship between the criminal and the victim, whether the body is inserted, and whether coercive means are used. In addition, as a result of the potential class analysis of criminal methods, there was a difference in the distance of movement of sex crimes according to the potential (group) type of sex crimes. Finally, by synthesizing the results, the development direction of geographic profiling required for evidence-based policing and limitations were discussed due to the problem of analysis data.
