Bones on rooftop may be from 9/11 victims

Construction workers have found bone fragments that may be the remains of those who died in the World Trade Center attacks on the roof of a neighboring skyscraper damaged on September 11, 2001, a city official said Tuesday.
The fragments, handed to the office of the city's chief medical examiner who will establish whether they are human and try to identify them, were found during work to dismantle the Deutsche Bank building.
The 41 story building was struck by falling debris when the Twin Towers collapsed and has been vacant ever since, pending a decision on how to safely demolish it.
Ellen Borakove, director of public affairs for the city's Office of the Chief Medical Examiner, said less than 10 small fragments had been found on the roof over the past week."We don't know yet if they are human. We have to do some further examination to determine that," Borakove said, adding those tests could take about a week."If they do turn out to be human, we will have to see if we can extract DNA to see if we can identify them," she said.
