NEW YORK —
Some 2,750 people died at the World Trade Center in the 2001 terrorist attacks, but only 1,634 people have been identified.
“We have been monitoring the World Trade Center site over time and monitoring the construction,” said Ellen Borakove, a spokeswoman for the medical examiner’s office. “And if they see any material that could possibly contain human remains, we collect that material.”
About 9,000 human remains recovered from the ruins of the World Trade Center remain unidentified because they are too degraded to match victims by DNA identification.
