NEW YORK (AP) -- About 300 human bone fragments have been found in recent days on the roof of a skyscraper badly damaged by the collapse of the World Trade Center, officials said Thursday.
Workers have been removing toxic chemicals and trade center dust from the former Deutsche Bank building before they begin dismantling it floor by floor. They found 10 bone fragments on the roof when the cleanup began last fall and 80 more in recent weeks.
Two fire department battalion chiefs and retired firefighters joined in the search for remains this week after some relatives of people killed in the attacks of Sept. 11, 2001, complained that recovery experts should help the construction workers.
Recovered remains are taken to a DNA lab, and those that are identified are turned over to families. Those that can't be identified will be stored at a World Trade Center memorial.
