Abstract

Experiments were conducted to assess the effect of machine washing or brushing of clothing items on Gunshot Residue (GSR) patterns (gunpowder residues, lead, and copper, deposits) around bullet entrance holes. Results show that those treatments decrease considerably the amount and density of GSR. However, for close shooting distances not all of the GSR deposits are removed. Remaining patterns may be visualized by specific color reactions and used for shooting distance estimation.

摘要

开展了实验，以评估对衣物进行机洗或刷洗对子弹入口孔周围枪火残留物（GSR）模式（火药残留、铅和铜沉积物）的影响。结果表明，这些处理方法会大幅减少GSR的数量和密度。然而，对于近距离射击，并非所有的GSR沉积物都会被清除。剩余的模式可通过特定的颜色反应显现出来，并用于估计射击距离。
