National DNA Index System
National DNA Index System (Forensic Science)
The National DNA Index System (NDIS) is an electronic resource of DNA profiles designed to aid in criminal investigations as well as searches for missing persons at the national level. Established in response to the Violent Crime Control and Law Enforcement Act of 1994 and operated by the Federal Bureau of Investigation (FBI), NDIS represents the highest level in the Combined DNA Index System (CODIS) hierarchy. CODIS, which began as a pilot project in 1990, represents a database of DNA profiles collected by law-enforcement agencies across the United States. CODIS is a computerized DNA profile processing system that provides law-enforcement agencies with the ability to search electronically for DNA profile matches. The CODIS hierarchy includes support at the national (NDIS), state (State DNA Index System, or SDIS), and local (Local DNA Index System, or LDIS) levels. DNA profiles from the state and local levels constitute NDIS.
The primary purpose of NDIS is to assist in criminal investigations across state and local levels by providing an electronic database containing DNA profiles from participating laboratories across states. NDIS offers law-enforcement agencies in different states the opportunity to search for possible matches between suspected or convicted criminals and DNA profiles obtained from the scenes of unsolved crimes. This index system also enables the identification of serial offenders.
