This study was conducted to explore how to approach and prevent crimes that have no identifiable connection between the crime and the victim while causing serious harm including mass stabbing in Korea. As a result of literature review, such violence is defined as a targeted violence overseas, and various efforts have been reported to counter it. This type of crime does not occur random, but occurs in pursuit of a specific target with intentions and plans, and that various warning behaviors appear in the process of perpetrator moving toward and preparing for the violent act. In addition, it was found that threat assessment and management are being studied and introduced in various countries to detect such warning behavior, evaluate threat of concerned individual or circumstance, and intervene proactively based on them. The necessity of introducing a threat assessment and management system for preventive intervention of domestic targeted violence were discussed.
