Whether it's a dismemberment, a cremated corpse, or a case involving skeletal remains, the key to solving any case that involves forensic anthropology is identifying the source of the body.
Essentially, the pivotal question, "who is he," is the foundation of solving such cases.
Just like doctors at grassroots hospitals, ordinary grassroots forensic doctors primarily rely on instruments and equipment for identification.
Of course, high-end forensic experts won't start boiling water right away either.
Normally, DNA is tested first; they'll attempt to retrieve fingerprints, and if there are none, they'll look for any unique markings such as fingerprints or medical identifiers like steel plates and screws.
Generally speaking, it is believed that having steel screws implanted in a regular hospital is the most effective proof of identity for an ordinary person.
