This is a pretty sad tale- construction workers in New York have found what appear to be bone fragments from the victims of 9/11. They were discovered on the Deutsche Bank building which was hit by falling debris when the Twin Towers collapsed- the building has been vacant ever since. It was only in February of this year that the effort to identify the victims from remains was halted.
The statistics are pretty awful- of 2,749 victims only 292 full bodies were ever recovered. Perhaps some of these newly found remains can be ID'd by DNA testing. It must be terrible for the families of those whose remains have never been identified at all- I can't begin to imagine what that must be like, but it seems to me that it would be as if their loved ones had just vanished from the face of the Earth.
