Abstract:
Objective To study the relationship between GSR and firing distance, and to discuss whether the relationship can be used to estimate the firing distance. MethodsShotting porkets with "5.4" hand gun at the firing distance of 5, 10, 15, 20, 30, 40, 50, 60, 70, 80, 90, 120cm respectively, then observing the distributing and element of GSR with SEM/EDX and finally building the equation of regression. ResultsThe relationship between the quantity of GSR and firing distance is linear and the equation is built. When the firing distance is from 10 to 90cm, the result is preferably. ConclusionWe can estimate the "5.4"hand gun firing distance through testing GSR around gunshot wounds.
