目的 研究亲密关系命案中涉及伪装死因及方式等行为发生频数、与死亡性质的相关性、法医学特征以及与真实死因的对应关系,提高亲密关系命案中伪装行为的法医学认识.方法 在 100 例已破亲密关系命案中,利用卡方检验分析伪装行为与亲密关系、死因、致伤工具、损伤程度、抵抗伤、死亡时间等要素的相关性,分析伪装死因与真实死因之间的对应关系.结果 100 例亲密关系命案中,22 例涉及伪装行为.10 例伪装"自杀"案件中,伪装死因6例(60%);在12个"意外"案件中,伪装死因10例(83.33%).伪装方式在"自杀"案件中出现3例(30%);"意外"案件仅出现1例(8.3%).扼死案例中伪装死因的比例相对较高(35.71%,10/28).损伤程度轻的案例中,伪装死因的比例较高(15/46).无抵抗伤的案例中,伪装死因的比例为 23.19%(16/69).在真实死因中,扼死最常被伪装.结论 亲密关系不会影响伪装死因及方式等行为的发生及分布.伪装"意外"性质的案件数量多于"自杀"案件.扼死、投毒等杀人手段由于不容易留下明显的损伤,容易被伪装成自杀、他杀.
Forensic analysis of staging behavior in 100 intimate partner homicides
Objective To investigate the frequency of staging behaviors involved in intimate partner homicide cases,as well as their correlation with the nature of death,medico-legal characteristics,and their correspondence with real causes of death.In order to improve the forensic understanding of staging behaviors in intimate partner homicide cases.Methods Using 100 investigated intimate homicides,forensic elements were statistically analyzed.The Chi square test was used to analyze the correlation between staging behavior and intimate partners,cause of death,injury weapons,time of death,degree of injury,resistance injury,postmortem intervals,and other specific elements and the occurrence of staging behavior.The corresponding partner between staging cause of death and real cause of death was clarified.Results Among the 100 intimate partner homicides,22 involved staging behaviors.Out of 10 cases of"staging"suicide,6 cases(60%)were attributed to staged causes of death.Among the 12"accidental"cases,there were 10 cases(83.33%)of staged causes of death.Staging manner of death appeared in 3 cases(30%)of"suicide"cases,and there was only one in"accidental"case(8.3%).The proportion of staged causes of death in strangulation cases was relatively high(35.71%,10/28).In cases with mild damage,the proportion of staging causes of death is higher(15/46).In cases without defense injuries,the proportion of staged causes of death was 23.19%(16/69).Among the true causes of death,strangulation in homicide was most commonly staged.Conclusion Different relationships of intimate partners did not affect the occurrence and distribution of staging behaviors.In cases involving staging behavior,the number of cases with staging as"accidental"nature of death is higher than that of"suicide"cases.The deaths with minor surface injuries such as strangulation and poisoning can be easily staging as suicide or accident.
