Common questions

Why is a BPN assigned to every fragment rather than only to intact bodies?+

Mass-fatality scenes involving blast, fire, or transport disasters often fragment remains, and separate fragments may belong to different individuals or the same one. Assigning a BPN to each fragment as found preserves the ability to later reassociate fragments to a single identity through DNA or other matching, rather than losing that link at recovery.

How does the BPN system help prevent double counting of victims?+

Because each BPN records the exact find location and associated effects at recovery, reconciliation teams can distinguish separate fragments of one individual scattered across a scene from fragments belonging to different individuals, reducing the risk of counting one person's remains as multiple victims.
