Why are firearms examinations important in criminal investigations?

Firearms examinations are crucial in criminal investigations primarily because they provide evidence that can link a weapon to a suspect. When a firearm is recovered from a crime scene, forensic experts can analyze ballistic fingerprints, which include unique markings left on bullets and cartridge casings when a gun is fired. This analysis allows investigators to trace the firearm back to the suspect who may have used it in the crime.

Moreover, firearms examinations can also reveal other important information, such as whether a firearm has been fired recently or if a bullet found at a crime scene matches a specific weapon. This strong connection between the firearm and a suspect can significantly bolster the case against an individual and provide essential leads for investigators.

While establishing a timeline of events, assessing proper storage of firearms, and determining legality can be part of a broader investigation, they do not directly contribute to establishing a connection between a suspect and a crime scene, which is the primary importance of firearms examinations.
