The National Missing and Unidentified Persons System (NamUs)

Overview of NamUs:

On any given day in the United States, there are between 80,000 and 90,000 individuals actively reported missing to the National Crime Information Center (NCIC). It is estimated that there are also between 13,000 and 40,000 unidentified decedents recovered throughout the United States, with an additional 1,000 unidentified decedents being added to this number each year. The missing and unidentified person problem in the United States has been deemed our nation's silent mass disaster.

The National Missing and Unidentified Persons System (NamUs) is a powerful, free tool to assist law enforcement officers, medical examiners, coroners, allied criminal justice professionals, and the family members of missing persons in resolving these cold cases. NamUs combines online database technology with forensic and analytical resources to solve long-term missing and unidentified person cases. NamUs resources also include a team of expert Regional System Administrators (RSAs) who assist users with case management and biometric support services. The online databases contain detailed case information that allows for searching using a wide variety of identifiers, such as physical features, dental records and tattoos, while protecting sensitive case data which is restricted and only viewable by medical examiners, coroners, law enforcement, clearinghouse personnel, and other allied forensic specialists.

Visit the Laboratory of Forensic Anthropology web page for more information.

Training and Analysis:

The NamUs Training and Analysis Division provides analytical support and training to NamUs stakeholders throughout the United States. Analytical resources include NCIC offline searches, NamUs database searches for potential matches between missing and unidentified persons, and searches of both public and law enforcement sensitive databases for information to assist in the location of persons reported missing, family members for DNA collections, and next of kin. NamUs also partners with the Federal Bureau of Investigation's Violent Criminal Apprehension Program (ViCAP) to coordinate ViCAP resources and share case information.

NamUs works with law enforcement agencies across the country and can assist with outreach or provide any needed technical assistance. NamUs also provides free training related to the NamUs databases and other resources.
