Shots fired from close range leave tell-tale marks called stippling, or tattooing. These marks are discolorations of the skin caused by burning gunpowder. Evidence of contact with hot gunpowder can be seen just above the “V” opening of the shirt (the blackened area) in the photograph above. The person who wore this shirt was the victim of a shooting at close range—less than a foot away—with a 9mm pistol. Notice there’s no hole in the back of the shirt. No hole, no exit wound. The bullet stayed in the body even from a shot at this short distance.
The next photograph (post autopsy) - *WARNING. REAL GUNSHOT WOUND - GRAPHIC *- is of the wound the victim received in the upper image.
The wound is round and neat, and it’s approximately the diameter of an ink pen. It’s not like the ones we see on television where half the guy’s body is blown into oblivion or beyond by a couple of bullets from a hero’s gun. Sometimes exit wounds are nearly as small as the entrance wound. The amount of damage and path of travel depends on the type ammunition used and what the bullet struck as it makes it way through the body. I’ve seen officers who easily mistook exit wounds for entrance wounds, at first glance. A close examination reveals stark differences. Exit wounds normally present pieces of avulsed flesh angled slightly away from the wound. Normally, there’s also no trace of gunshot residue around the outside of the wound.
In the picture below, the hot bullet entered the flesh leaving a gray-black ring around the wound. The tiny black dots are the stippling, or tattooing.
The impact of the bullet and gases striking the tissue also left a distinct bruising (ecchymosis) around the wound.
Contact wounds caused by the barrel of a gun touching the skin when the weapon is fired may present the imprint of the muzzle. The wounds sometimes show an abrasion ring (a dark circle around the wound) that’s caused as the hot gases from the weapon enters the flesh. The force of the gas blows the skin and tissue back against the gun’s muzzle, leaving the circular imprint.
