"With an estimated 4,400 unidentified human remains cases every year and close to 100,000 active missing persons cases on any given day, the nation needed a central repository for case records. Therefore, the National Institute of Justice created NamUs, the first national repository for missing persons and unidentified decedent records accessible to law enforcement agencies, medical examiners, coroners and the public. More than 2,000 missing persons cases and more than 5,000 unidentified decedent cases have already been entered into NamUs, and the numbers continue to grow."
