Human remains thought to be from victims of the Sept. 11 attacks have been discovered by utility workers removing rubble from manholes where the World Trade Center once stood, a city official said on Friday (October 20). Ellen Borakove, a spokeswoman for New York's chief medical examiner, said human remains were recovered and experts would be trying to identify those remains. She said the office would run DNA tests in hopes of matching the parts with profiles gathered since the attacks. Local media reports said a few arm and leg bones as well as identification cards had been found on Thursday (October 19), but Borakove would not confirm that. More than five years after the attacks, 1,150 of the 2,749 victims of the New York attack have either not been identified or recovered. Families of victims have called repeatedly for a thorough search of the grounds by independent investigators. "I have to say today that I am sick, I am disgusted, I am outraged, but I am not surprised" said Sally Regenhard whose son was one of those who died in the 9/11 attacks. "Over the last several years, I and other family groups have been asserting the fact that human remains remain at Ground Zero," she said. The remains were found near a spot where families read aloud the names of relatives killed in the attacks at commemoration ceremonies each Sept. 11. New York Mayor Michael Bloomberg's office did not immediately respond to phone calls asking why an independent investigation had not occurred. The mayor said in a weekly radio address the city would conduct a fresh search of manholes but that recovery efforts in an area as big as the site could not be perfect. The manholes had been covered by a temporary road paved soon after the attacks that allowed cranes in to remove debris.
