摘要
本文介绍1例用塑料扎带扎(勒)颈致人窒息死亡的案例。死者为一青少年女性,独自登山时与家人失去联系,次日尸体在山上被发现。死者双手、双脚及颈部见塑料扎带捆扎,去除扎带后,颈部暴露一宽0.8cm的环形条状闭合索沟。死者颜面部轻度淤血,球睑结膜点片状出血,口鼻部与气管见较多蕈样泡沫,颈部索沟皮下及肌肉未见显著出血;镜下检验见颈部索沟皮肤角质层减少、细胞间距变窄、细胞及细胞核变长,肺淤血、出血,心间质灶性出血、部分心肌纤维断裂呈波浪样变,大脑细胞水肿、神经元缺氧性改变等;理化检验未检见常见毒物。综上分析,死者符合塑料扎带扎(勒)颈窒息死亡。通过死者口鼻部及气管较多蕈样泡沫,颜面部淤血、出血程度较轻等征象分析,颈部扎带未能完全闭合双侧颈动、静脉及气管,说明死者死亡过程持续时间较长。此外,本案利用胃内容物消化程度等指标推断的死亡时间与嫌疑人供述的作案时间存在数小时差异,通过查阅相关文献发现,利用胃内容消化程度推断死亡时间在个别案件中存在较大误差,其原因与个人体质、现场环境、饮食情况等因素有关,提示法医同行在利用早期尸体现象推断死亡时间时不能过度依赖单一指标,要尽可能综合案情、现场环境、饮食情况、个人体质等因素分析。
This article introduces a case of asphyxial death caused by using plastic ties to tie(strangle)the neck.The deceased was a teenage female who lost contact with her family while climbing the mountain alone.The body was found on the mountain the next day.The deceased’s hands,feet,and neck were tied with plastic ties.After removing the ties,a 0.8cm wide circular closed cable groove was exposed on the neck.Mild congestion on the face of the deceased,patchy bleeding on the bulbar conjunctiva,more mushroom-like foam in the mouth,nose and trachea,no significant bleeding under the neck sulcus and muscles;Forensic histopathology revealed a decrease in the stratum corneum of the cervical sulcus skin,narrowing of cell spacing,elongation of cells and nuclei,pulmonary congestion and bleeding,focal interstitial bleeding in the heart,wave like changes in some myocardialfibers,edema of brain cells,and hypoxic changes in neurons;No toxic substances such as ethanol,barbital,phenobarbital,scobarbital,and tetramine were detected in the physical and chemical tests.Based on the above analysis,the deceased was found to have died from asphyxia due to external compression of the neck caused by plasticties.According to the analysis of signs such as more mushroom-like foam in the mouth,nose and trachea of the deceased,congestion in the face and mild bleeding,the neck bandage failed to completely close bilateral carotid arteries,veins and trachea,indicating that the death process of the deceased lasted for a long time.In addition,there is a difference of several hours between the estimated time of death using indicators such as the degree of digestion of gastric contents in this case and the time of crime confessed by the suspect.Through reviewing relevant literature,it was found that there is a significant error in using the degree of digestion of gastric contents to estimate the time of death in individual cases,which is related to factors such as personal constitution,on-site environment,and dietary conditions,It is suggested that fore
