National Integrated Ballistic Information Network (NIBIN)
NIBIN evaluates ballistic evidence to identify shooters and connect a gun to multiple crime scenes.
# 1 – Did you know?
- When a gun is fired, it leaves unique marks on the ammunition casings. Just like a person’s fingerprints, no two firearms leave the same marks on a casing.
# 2 – Did you know?
- Today’s technology takes a 3D image of ballistic evidence and identifies possible matches to evidence from other violent crime scenes, allowing law enforcement to connect separate shooting incidents and help identify those responsible.
