You mean to tell me it’s nearly NINE years later...and we still haven’t finished sifting through the rubble?
Even well after the collapse[s], some below-ground cavities that had been used for utility and infrastructure purposes were paved over without being searched for remains.
I believe this is the material that was sifted through.
The active search for the dead ended at the site in 2002 after a massive cleanup of 1.5 million tons of debris. About 20,000 pieces of human remains were found, but the DNA in thousands of those pieces was too damaged by heat, humidity and time to yield matches in the many tests forensic scientists have tried over the years.
More than 40 percent of the 2,749 Sept. 11 victims in New York have never been identified.
