National DNA Data Bank

The National DNA Data Bank (NDDB) maintains a collection of more then half a million DNA profiles. These profiles help investigators across the country solve crimes and help identify human remains. Regardless of police jurisdiction, the main goal of the NDDB is to help support criminal and humanitarian investigations by:

  • linking crimes together where there are no suspects
  • helping identify suspects
  • eliminating suspects where there is no match between a crime scene DNA profile and a convicted offender's DNA profile
  • determining if a serial offender is involved
  • identifying a victim of a crime
  • identifying human remains and assisting investigators, coroners and medical examiners to find missing persons
  • eliminating a voluntary donor from the focus of an investigation
