CODIS(mp) (Combined DNA Index System for Missing Persons): Also known as the National Missing Person DNA Database (NMPDD), CODIS(mp) is a database specifically designed to assemble data on missing persons and unidentified human remains cases. It was created in 2000 by the FBI using existing portions of the CODIS database. The searchable database includes information on nuclear and mitochondrial DNA obtained from unidentified remains, relatives of missing persons, and personal reference samples. Having both types of DNA profiles maximizes the potential for a successful identification.
