Forensic Analysis of Gunshot Wounds

A type of gunshot wound that shows an outward beveling of tissue. This means that the bullet's exit wound is larger than its entry wound.

A method used to preserve a bullet hole in clothing for forensic analysis . It involves carefully removing the clothing around the hole without folding or creasing the fabric.

This test is used to detect the presence of gunpowder residue on a person's hands. A positive test involves the presence of blue flecks, indicating nitrates from gunpowder.

A type of explosive that burns rapidly, producing a lot of gas but not a strong detonation.

A chemical compound that provides oxygen for the rapid combustion of gunpowder, acting as the oxidizer in the reaction.

The main features of a cartridge, which streamline the handling and use of ammunition. They include convenience, ease of loading, and protection from degradation. However, preventing priming compound loss is NOT a primary purpose.

The different parts of a cartridge case, including the bottleneck, case neck, case body, case shoulder, and straight-walled portions.

A mixture of nitrates, usually potassium nitrate, charcoal, and sulfur. This is used for the propulsion of bullets and shots in firearms.

Gunpowder that is designed with multiple holes to increase surface area. This allows for faster and more controlled burning.

A type of bullet designed for piercing armor, often made of hardened steel or tungsten.

A bullet that is made of an explosive or flammable material, designed to ignite upon impact with a target.

The component of a primer that contains the chemicals responsible for the initial combustion of the cartridge.

A type of primer where the priming mixture is located in a recessed cup in the center of the cartridge's base.

Markings that are left on a cartridge case during the firing process. These marks can be unique to a specific firearm.

Bullets that are made of lead, the simplest and most common type.

A type of bullet with explosives in the tip for target ignition.

Marks (striations) left on a bullet due to the rifling in a firearm barrel. These grooves are unique to each individual barrel and can be used to match bullets to guns.

The physical diameter of a firearm's barrel, measured from land to land (the raised portions between the grooves).

A bullet designed to create a larger wound channel by producing hydraulic jetting when it passes through tissue.

This refers to the marks that are left on a cartridge case when it is extracted from the chamber of a firearm.

A type of bullet that has a jacket made of a plated gilding metal, which protects the bullet and ensures it remains intact while being propelled towards its target.

A bullet designed to break apart upon impact, creating a spray of smaller fragments.

Locations where markings are made on pistol cartridges. They provide crucial evidence for forensics.

A systematic approach to examining firearm evidence, involving steps like analysis (assessing characteristics), comparison (finding matches), evaluation (weighing findings), and verification (confirming results).

A type of explosive that detonates or explodes rapidly, producing a powerful shockwave.

A type of bullet that leaves a trail of smoke or fire when it is fired, used to assist in tracking the bullet's path in the air.

A method of examining firearm evidence, using scientific principles to determine if a specific weapon fired a particular bullet or cartridge case.

A firearm, such as a rifle or shotgun, designed to be fired from the shoulder.

The energy possessed by a bullet as it exits the barrel of a firearm. It is a measure of a bullet's destructive potential.
