In December 2003, two young men decided to go shooting in the countryside near Montpellier, France. One accidentally shot the other. Upon crime scene examination and autopsy of the victim experts observed, at the right thorax, two round wounds, distanced 5mm from each other, presenting typical characteristics of entry wounds of bullets shot from a distance. Because of the presence of two clear cut round wounds, the Procurator suspected voluntary homicide. However, thanks to the balistics expertise, the authors concluded that all fragments belonged to a unique projectile, 22 Short caliber (Remington cartouche) of the frangible type. The barrel of the rifle infact presented an imperfection where the screw was fixed on the frontsite. The screw had obviously been changed, and the new screw was longer and therefore extended into the barrel, causing a small obstacle to the bullet when exiting the barrel. Shooting tests were performed, allowing the authors to conclude that a single bullet had fragmented before entering the body into two fragments. This lead the Procurator to consider the lesions consistent with an accident.
2003年12月,两名年轻男子决定在法国蒙彼利埃附近的乡村进行射击活动。其中一人意外射中了另一人。在对犯罪现场进行勘查以及对受害者进行尸检时,专家们在受害者右胸部发现了两处圆形伤口,彼此相距5毫米,呈现出远距离射击子弹入口伤口的典型特征。由于存在两处清晰的圆形伤口,检察官怀疑这是一起故意杀人案。然而,经过弹道学鉴定,作者得出结论,所有碎片都属于一颗独特的子弹,即易碎型的.22短弹口径(雷明顿弹壳)。事实上,步枪的枪管在准星固定螺丝处存在瑕疵。螺丝显然被更换过,新螺丝更长,因此伸进了枪管,导致子弹离开枪管时遇到一个小障碍。进行了射击测试,作者据此得出结论,一颗子弹在进入身体前就已分裂成两块碎片。这使得检察官认为这些损伤与一起意外事故相符。
