Abstract
|
|
|
The gross features of entrance wounds are critical points in the discrimination of range of gunshot injury and thereby in the investigation of manner of death. The incidence of gunshot injuries are extremely low in this country, and there have
been
only
few studies, related to the patterns of gunshot injury.
We performed an experimental study using porcine skin and five kinds of guns to document the objective characteristics of entrance according to the range of fire.
@ES The results were:
@EN 1. The entrances of M16A1 rifle showed characteristic six and three directional blackening in radial fashion due to muzzle breaks in the cases of contact and close-contact gunshot, respectively. These radiation blackening disappeared at 5cm
range.
2. The blackening of gunshot by rifles markedly decreased in the range of 15 to 20cm and no blackening was observed in the 50cm range in the cases of K-2 rifle. In the 100cm range gunshot, only bullet effects were observed in both M16A1 and K-2
rifles.
When clothes were applied over porcine skin, the blackening disappeared at 20cm range.
3. In the cases of pistols and revolver, the size of blackening corelated with the diameter of muzzle and blackening markedly decreased at the 5cm range and disappeared at 50cm range.
The present data would be used as adjunctive and objective criteria of gunshot injury investigation in Korea.
