NamUs 2.0 Database stores records of three case types: missing persons, unidentified persons (living and deceased), and unclaimed remains. It stores detailed biometric coding/classifications (e.g., dental and fingerprints) with associated high-resolution image files. NamUs staff assist with the acquisition and entry of biometric information, and forensic subject-matter experts perform secondary review of all biometric information to ensure accuracy and completeness. Authorized local, state, tribal, and federal law enforcement officers, as well as medical examiners, coroners, and allied forensic specialists can enter, manage, and view sensitive information. Public users can make missing person entries, which are vetted with appropriate criminal justice agencies prior to publication. The NCIC contains 21 files (7 property files and 14 person files), which include the Missing and Unidentified Person files. The NCIC stores detailed biographic data that can be associated with biometric systems, such as the Next Generation Identification System, the National Dental Image Repository, and the Combined DNA Index System. All authorized agencies can access NCIC through their appropriate state or federal Criminal Justice Information Services (CJIS) Systems Agency (CSA). Access is not available to the public. Potential matches between the Missing and Unidentified Person files are automatically generated and sent via daily system messages to the investigating agency and record-owning agency.
