Counting the bodies don’t always work, that’s the scary part. You don’t know recovered body fragments belong to how many people in a huge disaster, unless these parts are undisputable like heads, hearts and so on.
The initial count is always an estimation of how many went missing, with confirmed body parts forensically identified via examiniation or DNA tests, the death toll gets corrected.
Sometimes the missing person won’t be confirmed dead for months or even years, in which case a “presumed death” is announced by court for legal proceedings.
