Document Summary

Gunshot wounds can be classified in two manners: penetrating creating an entrance wound but not an exit wound. Projectile must be recovered from body to confirm this: perforating creates both an entrance and exit wound. As distance of barrel increases from the skin, gas diminished and only unburned powder and bullet can penetrate skin. Stippling: created by unburned powder on skin around defect produced by bullet. If gunpowder is on someone, the weapon was close to that person when it was fired. Gunshot exit wounds are typically lacerated, not always larger than entrance wounds. Directionality: direction from which bullet enters and traverses the body. Entrance wounds: are generally round due to being fired from a rifled barrel: rotation of bullet during flight causes wound to be round or elliptical. Exit wounds: are generally irregular in shape: alterations are made to bullets affect the probability of exiting. Gun powder is most likely to be at the entrance wound.
