A 53-year-old man was found dead after a fire at his residence had been extinguished. Although a pistol was recovered beside the body, external examination was unable to indicate any gunshot wound because of severe charring of the body. Postmortem computed tomography (CT) scan performed prior to autopsy suggested an entrance gunshot wound in the posterior pharynx with loss of soft tissue and an internal bullet path through the right anterior and posterior parts of the occipital bone. Autopsy revealed an entrance gunshot wound with hemorrhage in the soft tissue of the posterior pharynx, massive contusion of the right occipital lobe, and subarachnoid hemorrhage in the right temporal lobe, both occipital lobes and the superior surface of the left cerebellar hemisphere, thus being consistent with the findings of postmortem CT. A carboxyhemoglobin concentration of 5% in blood from the cadaver was consistent with the lack of soot deposition from the larynx to the bronchus. These observations confirmed that death had been caused by an intraoral gunshot resulting in severe brain damage, before the body had been burned.
一名53岁男子在其住所火灾扑灭后被发现死亡。尽管在尸体旁找到了一把手枪,但由于尸体严重烧焦,外部检查无法发现任何枪伤。尸检前进行的尸检计算机断层扫描(CT)显示,咽后部有一处枪伤入口,软组织缺失,子弹内部路径穿过枕骨右前部和后部。尸检发现咽后部软组织有枪伤入口伴出血,右枕叶大量挫伤,右颞叶、双侧枕叶及左小脑半球上表面蛛网膜下腔出血,与尸检CT结果一致。尸体血液中碳氧血红蛋白浓度为5%,与从喉部到支气管没有烟灰沉积相符。这些观察结果证实,死亡是由口内枪伤导致严重脑损伤所致,发生在尸体被焚烧之前。
