How does the DNA Databank work?

DNA evidence is collected from a crime scene, and analyzed by a forensic laboratory accredited in DNA testing. A scientist develops a DNA “profile” and uploads it to the state DNA Databank. That profile is then run against the convicted-offender DNA profiles in the State Databank to determine if a match exists. In addition, profiles from other unsolved cases are compared against it to identify serial crimes. The profile is uploaded to the Federal DNA Index System for comparison with DNA profiles from other states. DNA profiles remain in the Federal Databank and are regularly searched against new profiles as they are added to the system.
