Summary

The Attorney General must keep and run a national system called the National Missing and Unidentified Persons System (NamUs). The National Institute of Justice will manage NamUs, and it can be run through an agreement with an eligible organization. NamUs must serve as a national online clearinghouse and resource center. It must provide a searchable database, free forensic services to help identify people and remains, investigative support for law enforcement, help and training for families, coordination with State and local service providers, and outreach such as help with Missing Person Day events. Money for NamUs can be used to hire staff, build and improve technology, contract for services, and do forensic testing (for example DNA, dental, fingerprints, and anthropology). Funds can train police and medical examiners, help feed data to NCIC and NamUs, report every unidentified deceased person to local authorities, take part in Missing Person Days and DNA collections, run research and analytics, and create a secure nationwide incident-response tool for professionals and families. The changes in this law apply to reports made before, on, or after December 27, 2022.
