Hemorrhagic petechiae in the conjunctiva and the skin have been related to type of suspension and body height of the victims of hangings. In 265 cases of hanging, we retrospectively examined whether petechiae relate to type of suspension, body weight and height, body mass index (BMI), age, sex, type and thickness of the ligature, and blood alcohol content. The type of suspension was divided into completely suspended, incompletely suspended, and found with feet touching the ground. There was no significant difference in the frequency of petechiae between the feet touching the ground and complete suspension, and they were therefore considered as one group (complete suspensions). Incomplete suspensions had more (58.7%) petechiae than the complete suspension group (30.2%). Statistical analysis showed that incomplete suspension was significantly stronger related to the development of petechiae than complete suspension. Body mass index was the only variable able to add information to the type of suspension. In victims of incomplete hangings, high BMI yielded 2.58 times higher probability of developing petechiae than low BMI. These findings suggest that body size may contribute to the development of petechiae in hangings.
结膜和皮肤的出血性瘀点与绞刑受害者的悬吊类型和身高有关。在265例绞刑案件中，我们回顾性研究了瘀点是否与悬吊类型、体重和身高、体重指数（BMI）、年龄、性别、绳索类型和粗细以及血液酒精含量有关。悬吊类型分为完全悬吊、不完全悬吊和双脚着地被发现。双脚着地和完全悬吊的瘀点出现频率无显著差异，因此将它们视为一组（完全悬吊）。不完全悬吊的瘀点出现比例（58.7%）高于完全悬吊组（30.2%）。统计分析表明，不完全悬吊与瘀点形成的相关性显著强于完全悬吊。体重指数是唯一能为悬吊类型增加信息的变量。在不完全绞刑的受害者中，高BMI出现瘀点的概率是低BMI的2.58倍。这些发现表明，体型可能与绞刑中瘀点的形成有关。
