An Interesting Gunshot Residue Pattern

The presence of lead, copper, and antimony (Sb, Cu, and Pb) was shown on the left back and right palm by use of anodic stripping voltammetry (ASV). These data are consistent with a cross overhand held weapon (left over right). The use of ASV for gunshot residue (trace elements) is an alternative approach in that it allows observation of the entire three element (Sb, Cu. Pb) pattern.
