The National Missing and Unidentified Persons System (NamUs) is a national centralized repository and resource center for missing persons and unidentified decedent records. NamUs is a free online system that can be searched by medical examiners, coroners, law enforcement officials and the general public from all over the country in hopes of resolving these cases.
The Missing Persons Database contains information about missing persons that can be entered by anyone; however before it appears as a case on NamUs, the information is verified. NamUs provides a user with a variety of resources, including the ability to print missing persons posters and receive free biometric collection and testing assistance. Other resources include links to state clearinghouses, medical examiner and coroner offices, law enforcement agencies, victim assistance groups and pertinent legislation.
The Unidentified Persons Database contains information entered by medical examiners and coroners. Unidentified persons are people who have died and whose bodies have not been identified. Anyone can search this database using characteristics such as sex, race, distinct body features and even dental information.
The newly added UnClaimed Persons database (UCP) contains information about deceased persons who have been identified by name, but for whom no next of kin or family member has been identified or located to claim the body for burial or other disposition. Only medical examiners and coroners may enter cases in the UCP database. However, the database is searchable by the public using a missing person's name and year of birth.
When a new missing persons or unidentified decedent case is entered into NamUs, the system automatically performs cross-matching comparisons between the databases, searching for matches or similarities between cases.
NamUs provides free DNA testing and other forensic services, such as anthropology and odontology assistance. NamUs' Missing Persons Database and Unidentified Persons Database are now available in Spanish.
