A comparative study of 174 homicidal and 105 suicidal sharp force deaths in the Stockholm area is presented in order to identify variables of importance in the differentiation between homicides and suicides. In homicides, a significantly (p < 0.05) higher number of cut and stab wounds were seen in the head, upper and lower extremities and a significantly higher number of vertical stab wounds were found in the chest. Lower numbers were seen in the wrist and the crook of the arm. When counting the injured areas, irrespective of the number of injuries, abdominal wounds and horizontal chest stab wounds were also significantly more often found in victims of homicide. Injuries to the back and to the genitals were not seen in suicides. The suicide victims were significantly older and had significantly lower blood alcohol levels. A new variable pointing at a statistically significant difference between homicides and suicides was found: In homicides, stab wounds with a horizontal axis of entrance wound in the chest was found to be less common than those with a vertical axis. Other variables studied were prevalence of defence and tentative wounds, farewell notes and suicidal ideation, earlier parasuicides, venue, gender of the victims and the types of sharp objects used.
本文对斯德哥尔摩地区174例他杀和105例自杀锐器伤致死案例进行了对比研究，以确定在区分他杀和自杀方面具有重要意义的变量。在他杀案例中，头部、上肢和下肢的切割伤和刺伤数量显著更多（p < 0.05），胸部的垂直刺伤数量也显著更多。手腕和肘部的伤口数量较少。在计算受伤部位时，无论受伤数量多少，腹部伤口和胸部水平刺伤在他杀受害者中也明显更为常见。自杀案例中未发现背部和生殖器受伤情况。自杀受害者年龄显著更大，血液酒精含量显著更低。发现了一个表明他杀和自杀之间存在统计学显著差异的新变量：在他杀案例中，胸部伤口入口轴为水平的刺伤比垂直轴的刺伤更少见。研究的其他变量包括防御伤和试探伤的发生率、遗书和自杀意念、既往自杀未遂史、案发地点、受害者性别以及所用锐器类型。
