The body of a man was found in a workshop at the back of his home, a metal pipe embedded in his chest. In the immediate vicinity of the body, among various tools, was a machine containing a holster hit of lead shot evoking a mole-trap-type "taupe gun" (mole gun). The findings at the scene and the presence of a metal tube, sinkers, and a flock in the chest are in favour of the use of a homemade firearm. The autopsy and CT scan revealed atypical ballistic thoracic trauma responsible for a dilaceration of both the heart and thoracic aorta that caused the death. The autopsy also found a contused wound at the back of the skull without intracranial lesion, which may be due to the fall of the victim after the thoracic trauma. There is no other traumatic lesion and in particular no lesion of seizure, constraint, or defense. Toxicological analyses revealed the presence of alcoholic impregnation at the time of death. These findings, confronted with the expertise of a balistician, made it possible to understand how the victim used a mole gun to cause these lesions. A metal tube was used as a cannon to aim more surely at the heart but also as a means of triggering the propulsion mechanism of the trap without having to stretch out the arm. The tube, thinner than the barrel, had disengaged from its tip to be embedded with the lead shot in the chest of the victim.
在其家后院的一个车间里发现了一具男子尸体，一根金属管嵌入其胸部。在尸体附近，除了各种工具外，还有一台机器，里面装有一管铅弹，这让人联想到一种捕鼹鼠用的“诱捕枪”（鼹鼠枪）。现场的发现以及胸部的金属管、坠子和一团羽毛都表明使用了自制枪支。尸检和 CT 扫描显示，非典型的弹道性胸部创伤导致心脏和胸主动脉撕裂，这是死亡的原因。尸检还在后脑勺发现一处挫伤伤口，但没有颅内损伤，这可能是由于受害者在胸部创伤后摔倒所致。没有其他创伤性损伤，特别是没有癫痫、约束或防御性损伤。毒理学分析显示死亡时存在酒精浸渍。这些发现，再加上弹道专家的专业知识，使人们能够了解受害者如何使用鼹鼠枪造成这些损伤。金属管被用作大炮，以更准确地瞄准心脏，同时也作为触发陷阱推进机制的手段，而无需伸出手臂。由于管子比枪管细，所以从其尖端脱离，与铅弹一起嵌入受害者的胸部。
