NamUs stands for the National Missing and Unidentified Persons System. It is a free online database in the United States that helps law enforcement, families, and the public find missing persons and identify unidentified remains. The system aims to provide a centralized resource for sharing information about cases across different jurisdictions. Launched in 2007, NamUs is managed by the U.S. Department of Justice. It includes detailed case information, such as descriptions, photographs, and circumstances surrounding disappearances or unidentified remains. The platform encourages collaboration among agencies and the public to help resolve these cases effectively.
