One of the most common questions encountered by forensic scientists is the determination of a person firing the weapon. In addition to mortality, firearm injuries also cause a massive burden on the health infrastructure, with 282,542 emergency discharges recorded in the USA between 20. Between 19, firearm-related injuries caused the death of 462,043 Americans. The difference in the rates was approximately twice in both cases. Homicide was more common among urban youth than suicide, which was more common in rural youth. In 2016, the second leading cause of death in children and adolescents was firearm-related injuries accounting for 15.4% of all deaths Almost two-thirds of these deaths (59%) resulted from homicide, with just over a third (35%) as a result of suicide. Other studies have estimated over 90 deaths every day caused by firearm-related injuries. Gunshot injuries account for the most homicides in the United States of America, accounting for an estimated 46 deaths every day. Globally, in 2016, 251,000 deaths resulted from firearms injuries caused by events not related to war. It is also essential to identify the path taken by the projectile to help determine the prognosis, workup, and treatment of gunshot wounds. This information can be extremely important in determining the manner of injury, especially in fatal wounds, to assist medico-legal and criminal investigation on whether the injury was suicidal or homicidal.

Gunshot injuries may result in death due to hemorrhage, organ damage, and wound infection. Also, they are required to investigate and deliberate the cause and manner of the injury, the entry and exit characteristics, distance and direction of fire, and the vitality of the wound.

The Forensic Pathologists examining a gunshot wound should document the type, size, shape, site, and location like in any other injury. While the forces causing the temporary cavity act for a brief period, the results could be longstanding. The injuries caused by the projectile can affect the permanent cavity, the damaged tissues along the path followed by the projectile, as well as the temporary cavity, the tissue surrounding the permanent cavity that is subject to temporary forces including radial acceleration, shear, stretch, and compression.

In addition to the injury and the projectile, forensic pathologists must have a working knowledge of the flame, gases, smoke, unburnt powder, metal scrapings, and grease from the barrel that accompanies the projectile and could become embedded in the surrounding skin or the injury tract. The study of these injuries is also called wound ballistics. These injuries are caused by penetration of the body with projectiles ejected from a barrel due to the ignition of gunpowder. Gunshot wounds are complex, violent, traumatic injuries commonly encountered in forensic practice.
