The National Missing and Unidentified Persons System, NamUs, is the first national online repository for missing persons records and unidentified decedent cases. It was launched in July 2007 by the Office of Justice Program’s National Institute of Justice.

NamUs is made up of two databases: (1) records of unidentified decedents (select "Unidentified Decedents”) and (2) missing persons reports (select “Missing Persons”).

Currently, the unidentified decedents database is searchable and available for medical examiners and coroners to upload their cases. The search capability of the missing persons database is in development; the site currently provides resources on State clearinghouses, medical examiners and coroners, law enforcement, victim assistance resources, and legislation.

In 2009, the two databases will be linked. Families, law enforcement agencies, medical examiners and coroners, victim advocates, and the general public will be able to search for matches between missing persons and unidentified decedent records.
