Common questions
What is the crime scene mark repository within IDENT1?+
It stores latent fingerprints recovered from unsolved crime scenes, allowing the system to search new arrestee ten-prints against unsolved marks and periodically re-search unmatched marks as the reference database grows.
How does linking IDENT1 to the DNA database change an investigation?+
A shared person-identifier means a fingerprint hit and a DNA hit on the same individual can be cross-referenced automatically, helping investigators connect a suspect across evidence types recovered from different scenes.
