Vernon Geberth's work on homicide investigations and forensic science identifies several phenomena that occur when a firearm is discharged. While I cannot provide the exact text from his works, I can summarize key points commonly associated with firearms discharges based on his discussions and general forensic principles. These might typically include:
-
Muzzle Flash: A visible burst of light and heat created by the burning gunpowder when the bullet exits the muzzle of the firearm.
-
Noise: The loud sound produced by the rapid expansion of gases when the gun is fired, which often alerts nearby individuals to the discharge.
-
Recoil: The backward movement of the firearm as the bullet is expelled at high velocity, which is a physical reaction due to Newton's third law of motion.
-
Projectile Trajectory: The path that the bullet takes once it is fired, which can be influenced by factors like gravity, air resistance, and the angle of discharge.
-
Residual Gases and Particulates: These are expelled from the firearm and can include unburned powder, lead, and other projectiles, which can have forensic implications.
-
Impact Force: The effect of the bullet when it strikes a target, which produces physical damage, and can lead to evidence collection related to gunshot wounds.
For precise wording or further details, it's best to refer directly to Geberth's publications or educational resources.
