Intensive gunshot residues at the exit wound: an examination using a head model.

The autopsy findings of intensive gunshot residues at the exit wound after a gunshot wound in the head led to an experimental investigation to clarify the mode of origin and intensity of these gunshot residues on the inner surface of the exit wound. For this purpose a simple skull/brain model was prepared. The results of the examination showed that with weapons of the same calibre distinct gunshot residues should be expected at the exit wound.
