Estimating Muzzle To Target Distance From The Physical Characteristics Of A Bullet Hole In Different Wood Substrates, Alan Lee
Student Theses
Determining the muzzle to target distance of a firearm discharge is an integral part in crime scene reconstruction. Shooter distance is most often estimated using the Modified Griess test, which can be used to visualize gunshot residue (GSR) patterns around bullet holes. However, this test has a 3- to 5-feet range limit as the plume of GSR particles can only travel a certain distance past the muzzle. The purpose in this study was to develop a new method that overcomes this range limitation by analyzing the physical damage characteristics of a bullet hole. Test fires were conducted with a .22 …
