A Photoluminescence Technique for Detection of Gunshot Residue
When a suspect has been apprehended following a shooting, detection of gunshot residue on his hands may provide significant evidence in the investigation. The determination of the firing distance (distance from weapon to target) by the distribution of gunshot residue around a bullet hole is also useful in various gunshot investigations. We describe here the results of a preliminary study of the application of photoluminescence techniques to gunshot residue detection. The key objective in this study was to develop a rapid, reliable, and convenient method of detection for use in the crime laboratory.
