The location of a gunshot entrance wound as well as the wound path trajectory are the main findings that help to determine the position from which a weapon was fired and thus distinguish firearm suicides from homicides and accidents. We present a case of a 28-year old man, who was found dead in his car. Because of an unusual position of the firearm, which was clamped into the steering wheel, and an unclear entrance/exit wound, an autopsy was performed. The deceased showed typical signs of a contact shotgun wound to the head with an entrance wound in the right temporal region and an exit wound in the midface. With the help of gunpowder attachments and a muzzle imprint at the entrance site, a wound channel from the right lower posterior part of the temporal region to the left anterior part of the mid-facial region could be reconstructed. The stellate wound in the midface was assessed as an atypical exit wound. The cause of death was a contact shotgun shot to the right temple with a consequent central regulatory failure due to extensive brain injury. The manner of death was concluded to be a suicide.
枪伤入口的位置以及伤口弹道轨迹是有助于确定开枪位置从而区分枪支自杀、他杀和意外事故的主要发现。我们报告一例28岁男性,其被发现死于车内。由于枪支被夹在方向盘上的不寻常位置以及入口/出口伤口不明确,遂进行了尸检。死者呈现典型的头部接触式霰弹枪伤体征,右侧颞部有一入口伤口,面部中部有一出口伤口。借助入口处的火药附着物和枪口印记,可重建从颞部右下后部至面部中部左前部的伤口通道。面部中部的星芒状伤口被判定为非典型出口伤口。死因是右侧太阳穴接触式霰弹枪射击,随后因广泛脑损伤导致中枢调节功能衰竭。死亡方式判定为自杀。
