Key result
Firing 0.45 caliber ammunition unexpectedly deposits primer-derived gunshot residue deep on bone under the periosteum.
Why the study?
The potential to detect primer-derived gunshot residue on bone to differentiate gunshot trauma from blunt trauma and establish gun-to-target distance was unexplored.
The detection of primer-derived gunshot residue on bone provides a potential method to differentiate gunshot trauma from blunt trauma and establish maximum gun-to-target distance for remote shootings.
GSR under periosteum after soft-tissue transit may confound forensic wound analysis; leaves open mechanisms of deep primer residue deposition.
Pork ribs with intact muscle tissue were used in an experimental attempt to identify bullet wipe on bone at distances from 1 to 6 feet with 0.45 caliber, full metal jacket ammunition. This resulted in the unexpected finding of primer-derived gunshot residue (GSR) deep within the wound tract. Of significance is the fact that the GSR was deposited on the bone, under the periosteum, after the bullet passed through a Ziploc bag and c. 1 inch of muscle tissue. It is also important to note that the GSR persisted on the bone after the periosteum was forcibly removed. The presence of primer-derived GSR on bone provides the potential to differentiate gunshot trauma from blunt trauma when the bone presents an atypical gunshot wound. In this study, the presence of gunshot primer residue at a distance of 6 feet demonstrates the potential for establishing maximum gun-to-target distance for remote shootings.

Berryman et al. (2010) studied Gunshot trauma. 0.45 caliber, full metal jacket ammunition fired at 1 to 6 feet was evaluated on Presence of primer-derived gunshot residue (GSR) on bone. Firing 0.45 caliber ammunition at distances of 1 to 6 feet resulted in the unexpected deposition of primer-derived gunshot residue deep within the wound tract on the bone under the periosteum.
