9/11 chapter closes

New York

The New York medical examiner’s office announced that it had exhausted the limits of DNA technology, and would have to suspend the effort to identify the remains of those killed in the World Trade Center. Scientists matched body parts to nearly 1,600 of the people who died in the Sept. 11 attacks in New York; they could not identify any remains for the other 1,161 victims. Authorities freeze-dried nearly 10,000 unmatched pieces of tissue found in the ruins, in case scientific breakthroughs can someday help link them to the missing. “Part of me is relieved that no tiny fragment was found of my husband,” said Meena Jerath, a 9/11 widow. “If only a small piece was found, I would wonder what happened to the rest of him.”
