Methods .The data were collected in 52 schizophrenia patients and 41 non-schizophrenia patients with a history of homicide. All subjects were interviewed in a semi-structured interview for evaluating the characteristics of homicidal behavioral. Software SPSS16.0 was used to compare the characteristics of homicide behavior and capacity of criminal liability between the two groups. Results .The differences were statistically significant between the two groups concerning the abnormal behavior prior to offense, criminal incentives and premeditation, crime concealment, motives, self-protection after offense, capacity for responsibility, stage of disease, personality traits and previous illness( P ＜0. 05 ). Multivariate logistic regression analysis suggested that criminal premeditation and self-protection after offense were positively correlated with the capacity of criminal liability, whereas the abnormal behavior and stage of disease were in negative correlation with the liability. Conclusion: The characteristics of homicidal behavior differ greatly between patients with schizophrenia and non-schizophrenia patients. Therefore, pre-trial assessments of the capacity of criminal liability should take into consideration of criminal premeditation, self-protection after offense, abnormal behavior and stage of disease.
