After investigation, Liu Moumou was unmarried and lived alone for a long time. In 2004, he was sentenced to criminal punishment due to trivial disputes and armed retaliation for harming others. Before the incident, there were conflicts with others due to trivial matters, which led to a psychological imbalance, and he injured two young women who had never known each other with a knife. In addition, it was verified that Liu Moumou was not mentally ill and had full capacity for criminal responsibility. On August 13, Liu Moumou was arrested by the procuratorial agency on suspicion of intentional homicide. (Edited by Zeng Chen)
