Firearms / Toolmarks
These analysts examine firearms and ammunition for operating features and defects. Bullets and cartridge casings may possess unique characteristics that help identify the firearms from which they were fired or suggest the make and model of the weapon. Gunshot residue and patterns are examined to determine the proximity of a firearm muzzle to a victim. Tools used during the commissions of crimes may leave unique, identifiable marks on surfaces that may link suspects to crimes. Specialists in this area of examination can also restore serial numbers that have been altered on metallic surfaces such as firearms, automobile engines, etc.
