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.
