1. Because in the past 36 years, 200,000 people were killed and over 40,000 bodies haven't been identified, so Fredy Peccerelli and his team are on a mission to help I.D. all the unknown bodies.
2. They extract DNA from the bodies through the bones, then compare it to the DNA of a living family member to make sure the victim''s body belongs to that family.
3. They used it by searching through the military documents to find victims.
