Gunshot residue, ten years later.
Gunshot residues may be central to a competent reconstruction of a shooting incident. When a young boy was shot in the neck by a playmate using a .22-caliber single-action revolver, permanent paralysis from mid-thorax downward ensued. Ten years later the victim sued the importer, the vendor, the German manufacturer, and the shooter's family. Investigative reports indicated "horseplay" and questionable emergency medical team care. Depositions were contradictory. The entry wound, removed at surgery, was fixed and processed for slides. The histopathologist referred to "black pigment granules" in the wound track. The 10-year-old slides and block were retrieved. The coverslip was removed from a representative slide that was examined under the scanning, x-ray dispersive microscope. The black granules contained amounts of lead, barium, and antimony far beyond any normal range. The firing range had to have been no greater than 6-12 in (15.24-30.48 cm). The case was promptly settled out of court.
