Mourning the Still Missing - "Of the 2,823 people believed killed in the attack, 1,102 have been identified, about 300 through DNA alone. About 19,550 body parts have been recovered, some through the sifting process at a Staten Island landfill. New York City officials said the sifting will continue and the identification process will go on for months. Those parts that cannot be identified will be retained, in case new techhnology makes it possible someday. In the meantime, families have held memorial services and planted trees in lieu of funerals and burials."
