This study was subjectively designed to analyze the issued thirty-three events to find out the perceived type of stress and level of stress in schizophrenic murder. And then, we examined the seven main murder patterns of schizophrenic murder. The stress perceived in homicidal schizophrenics were divided into nine stress factors such as conflicts with parents or family members, failure and frustration in occupation, not promoted, marital discords, unrealistic contents of thought. and so on. Especially, dominant stress factors happened before murdering were conflicts with parents or family members and unrealistic contents of thought. The murder methods of schizophrenic were characterized with several factors such as the pattern of murder, tools used, victims' body-condition, people targeted and peculiarities. Specifically, there were over-killing modes with tough tools such as the kitchen knife and hammers placed at home, the family members or parents targeted, the deep scars intensively distributed on the head and chest, the peculiarities like the eyeballs extracted from the face and amputated cord of victims' ankles, largely many defensive scars existed on arm and wrist, and so on. Based on these results, schizophrenic murders previously may experience a few murder-triggering stresses for a long time and revealed their own killing methods
