颈部软组织擦挫伤多见于他杀扼颈,抢救所致颈部损伤较为罕见。本文报道一起疑似他杀扼颈的中毒死亡案件,该案件的难点在于判断案件性质,案件的特殊之处在于报案人和知情人均为聋哑人员,沟通较为困难。死者窒息征象明显,同时存在颈部损伤。技术人员通过仔细的现场勘查、尸体检验和理化检验结果分析,并结合调查情况进行现场重建,确定了死者颈部损伤是在他人抢救死者时挤压死者颈部形成,排除了死者系被他人扼颈死亡的情况,从而确定了死者的死亡方式并非他杀,死者的死亡原因为可待因、地芬诺酯中毒死亡,最终排除了刑事案件。通过对该案案件性质的分析,为今后法医实践中判断死亡方式和案件性质提供参考。

The jugular parenchyma bruise/contusion is more commonly caused from homicidal throttling, rarely from life rescue. This paper reports a case of poisoning death yet being suspicious of homicide, focusing on the difficulty to judge the genuine causation of the case. For the case, both the informant and insider are deaf, therefore inconvenient to talk with, perplexing to render the discovery that the dead is obvious of suffocation sign and neck injury. Through on-site careful investigation, postmortem examination and physical/chemical test when combined with scene reconstruction, the victim was confirmed of death from overdosing codeine and diphenoxylate, and the neck injury being formed by other people to rescue him. Through this case, some referential cognition may be provided for judging the death cause and case origin in forensic practice.
