Over two decades after the 9/11 terrorist attacks on the World Trade Center, New York medical officials are still working to identify about 40% of unnamed victims.
Driving the news: Last week, just days before the U.S. was set commemorate the 22nd anniversary of 9/11, the New York medical examiner’s office said it identified two more victims of the attacks, which killed at least 2,753 people.
The big picture: Determining who the 9/11 victims were remains the largest and most-challenging forensic identification effort ever, according to the National Institute of Standards and Technologies (NIST).
