More difficult is the processing of the event by those who can only guess how their dear ones died. There were many who were trapped in pockets of rubble, literally buried alive. How much more agonizing to think of a husband, wife, son or daughter dying slowly this way.
I know a priest who was called to the scene to give last rites. He was warned by the firemen, "Father, don't expect to find whole bodies." He went through, as on a battlefield, blessing limbs, skulls, feet, hands. Then he came upon a finger with a wedding band. At that point he broke down completely and had to leave the scene.
