A study was conducted to assess the influence of a possible contamination of the victim's clothing by gunpowder residue on the estimation of shooting distance. The study was focused on the scenario in which the contamination might be caused by the surface on which the shot victim could fall. Contamination of two types of textile was examined after contact with two types of surfaces. One round was fired above those surfaces (the line of firing parallel to the surface) prior to the contact. It was found that few gunpowder residue particles could be transferred to the clothing. These findings should be taken into account when interpreting results for shooting distance estimation in cases when a minute quantity of gunpowder residue particles is found around the bullet entrance hole.
一项研究旨在评估枪击受害者衣物上可能因与射击表面接触而沾染火药痕迹对射击距离推断的影响。研究主要集中在以下场景:枪击受害者倒下的表面可能会造成衣物沾染。在与两种表面接触之前,先在这些表面上方射击一轮(射击线与表面平行)。研究发现,仅有少量火药痕迹颗粒会转移到衣物上。在弹着点周围发现少量火药痕迹颗粒时,在解释推断的射击距离结果时,应考虑到这些发现。
