South Korea implemented specific legislation titled the Act on Punishment of Crimes of Stalking ( APCS) on October 21, 2021, to address the issue of stalking. This study evaluated the risks associated with stalking incidents in South Korea by reviewing and analyzing legal cases with finalized judgments within the first year of the APCS. Data were collected through a systematic search of the Korean Supreme Court’s Written Judgment Management System database. We identified 193 stalking-related cases between October 21, 2021, and October 14, 2022. These cases were analyzed based on four risk profile criteria: profiles of stalkers and victims, the nature of stalker–victim relationships, motivations behind stalking, and patterns of stalking behavior. Further, we reviewed cases to which the APCS and the Criminal Act applied by analyzing stalker–victim relationships and the stalkers’ underlying motivations to assess the risks associated with stalking. Approximately 16.6% of stalkers were diagnosed with mental disorders, the most common disorder being psychosis. The average age of the victims was 42.84 years, with a higher prevalence of female victims compared to male ones. Predominantly, stalkers were former intimate partners of the victims, with most cases motivated by rejection. Direct contact methods, such as physical approaches, have been observed more frequently than indirect methods, such as repeated unwanted messages, or non-contact behaviors, including surveillance and loitering. The findings provide an up-to-date overview of the under-examined criminal stalking issue in South Korea.
