Traumatic Gunshot Wounds

In a hit-and-run fatality, a study of the injuries may help identify the vehicle. The points of impact on a body are particularly important and clothing must be closely examined for paint chips and parts of the vehicle that may be transferred on impact. Bumper impact sites on the legs should be measured from the heel. This may indicate the bumper height. A bumper fracture is often triangular in shape with the apex of the triangle pointing in the direction that a vehicle was moving. If a driver...

Stippling Gunshot

When the firing pin of a weapon strikes the primer, the resulting explosion ignites the gunpowder.

The presence and location of primer elements on the hands help to indicate who may have fired the weapon in question. Gunpowder comes out of the muzzle in two forms. 1....

Circumstances Surrounding Death

Harris Line Seen Ray

Identifications may be impossible to make based on the few remains discovered at the scene however, the circumstances in which the remains are discovered may allow an identification to be made. For example, if only a few pieces of a body are located in a burned-out house, an identification cannot be made based on any scientific testing. But, if the owner of the house was last seen in the house, or if there is no other reason to believe the remains are those of someone else, a pre- FIGURE 2.2...

Occasionally, marine life, more often in salt water, may feed on the skin of the face, especially around the mouth, nose,...

Shotgun Injuries

Loosecontact Shotgun

Unlike handguns and rifles which have lands-and-grooves cut on the inside of their barrels, shotguns have a smooth bore. Lands-and-grooves cause specific identifying features rifling on projectiles as they pass along the barrel. These markings allow examiners to test-fire weapons and compare test-fired bullets to those discovered in bodies. Since shotguns have no lands-and-grooves, their projectiles cannot be positively matched to those found at the scene or inside a body. A shotgun cartridge...

It is also common for this process to occur in winter months if the environment is warm. It is possible for an entire body to mummify in a only a few days to weeks. Once a body is in this...
