Introduction
A primary element in the analysis of many shooting incidents is distance determination—the distance from the gun muzzle to the entry wound. The criteria most commonly used in this determination is the presence or absence of gunshot residue, the pattern diameter, and the type and distribution of gunshot residue. However, common protocols fail to consider the effect that hair may have upon the deposition of gunshot residue. There have been recent cases in which the absence of gunshot residue on the scalp was classified as evidence of a distant-range gunshot when other evidence supported a close-range gunshot.
