The End of "9/11"

New York City officials are halting efforts to identify the remains of those killed in the 2001 terrorist attacks that destroyed the World Trade Center.

The city’s medical examiner's office says it has exhausted DNA technology that allowed it to match bodies and body parts to the list of the dead. The office says it has nearly 10,000 bone and tissue fragments it cannot identify.

No remains have been found for 1,161 people killed in the attacks, more than 40 percent of the 2,749 people killed overall. (source)
