600,000Individuals go missing every year
4,400Unidentified bodies are recovered each year
The Nation's Silent Mass Disaster
The sheer volume of missing and unidentified person cases poses one of the greatest challenges to agencies tasked with resolving these important cases.
Over 600,000 individuals go missing in the United States every year. Fortunately, many missing children and adults are quickly found, alive and well. However, tens of thousands of individuals remain missing for more than one year – what many agencies consider “cold cases”.
It is estimated that 4,400 unidentified bodies are recovered each year, with approximately 1,000 of those bodies remaining unidentified after one year.
NamUs is a national information clearinghouse and resource center for missing, unidentified, and unclaimed person cases across the United States. Funded and administered by the National Institute of Justice and managed through a contract with RTI International, all NamUs resources are provided at no cost to law enforcement, medical examiners, coroners, allied forensic professionals, and family members of missing persons.
