Prior to the NamUs launch in 2009, families with missing loved ones had few places to turn in their quest for answers. From 2005 through 2011, NFSTC worked with the National Institute of Justice to develop, deliver and operate the National Missing and Unidentified Persons System.

In 2011, Charles Heurich, program manager and leader of the NamUs team, was named winner of the Samuel J. Heyman Service to America Medals in the Justice and Law Enforcement category. The system was honored for its innovation and creativity in working to solve a major national law enforcement challenge.
