A deceptive case of gunshot entry wounds -- beware of frangible bullets

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.
