Study Notes
Forensic Firearm Examination
- Involves examining firearms and bullets found at crime scenes to establish connections between bullets, weapons, and individuals.
- Specialists utilize forensic processes to link specific bullets to their respective firearms, aiding in criminal investigations.
Techniques Used in Forensic Examination
- Obliterated serial numbers can be raised and recorded to identify the weapon's registered owner.
- Fingerprint analysis can be conducted on firearms and cartridges to find potential suspects.
Bullet Analysis
- Unique striations, or marks, on a bullet are created by the rifling inside a firearm's barrel as the bullet spins when fired.
- These rifling patterns are crucial for linking expended ammunition back to a specific weapon, providing important forensic evidence.
Limitations of Striation Evidence
- Striations on bullets are individualized, making them unique to each weapon, but they may change slightly after each round fired.
- To preserve the integrity of striation analysis, forensic ballistics examiners limit test firings to no more than five shots from a weapon found at a crime scene.
