The authors illustrate a peculiar case of murder-suicide committed with a homemade firearm loaded with 12-gauge cartridges (buckshot). The structure and function of this handcrafted firearm were simple but effective: an iron tube did duty as a barrel in this primitive firearm. The cartridges (modified by winding sticky tape around the external surface of the base) were inserted down one end of the tube (serving as the breech). A second iron tube with a larger diameter (so as to be able to run over each of the preloaded barrels) and with a jutting, cone-shaped metal wedge soldered to the base, was used as a rudimental firing pin. After loading the "barrel" with the modified cartridge, the gunman would ram the "firing pin" tube violently down to fire the shot. Autopsy of the woman's body showed the presence of 3 gunshot wounds caused by buckshot, while the man had a single buckshot wound in the head. Subsequent ballistic investigations enabled reconstruction of the event (typical of murder-suicide) and the functioning of the firearm, demonstrating its lethal nature, remarkably easy handling, and simplicity of production.
作者阐述了一起用装有12号霰弹（散弹）的自制枪支实施的谋杀自杀特殊案例。这支手工制作的枪支结构和功能简单却有效：在这支原始枪支中，一根铁管充当枪管。弹药筒（通过在底部外表面缠绕胶带进行改装）从管子一端（充当枪膛）插入。另一根直径更大的铁管（以便能够套在每个预装的枪管上），底部焊接有突出的锥形金属楔块，用作简易撞针。在“枪管”装入改装后的弹药筒后，枪手会猛烈向下撞击“撞针”管来开枪射击。对女性尸体的尸检显示有3处由霰弹造成的枪伤，而男性头部有一处霰弹伤。随后的弹道调查得以重现该事件（典型的谋杀自杀）以及枪支的运作情况，证明了其致命性、极易操作和制作简易。
