title: A simple method for collection of gunshot residues from clothing.
abstract: Simple equipment for the sampling of gunshot residue particles from clothing, inside of bags, pockets, etc, is described. Collection was achieved by vacuuming through a double filtration system constructed from a Nucleopore aerosol holder connected to an ordinary vacuum cleaner. The collected particles were examined by scanning electron microscopy. Good results were observed in functional tests of this equipment and the method has been introduced into casework in our laboratory. Various experiments on possible contamination of clothing by GSR particles were performed. The usefulness of clothing as evidence material in searching for GSR particles is discussed.
