17 years after the September 11 Attacks in New York, more than 1,100 victims have yet to be identified. But the New York Medical Examiner's Office is using a breakthrough in DNA analysis to lower that number.>> All the profiles that we generate today, this year, these are remains that we had no hopes of in the past.
So it's our job here with the Medical Examiner's Office to not only make these identifications, but also improve that process.>> In the past five years, the team of ten has made five more identifications due to steady advancements in DNA testing since 2001. The latest discovery was made this year when scientists placed bone fragments in a chamber filled with liquid nitrogen so they can be pulverized into a fine powder.
The more a bone is pulverized, the more likely DNA can be extracted. It's the latest effort in the largest forensic investigation in U.S. history involving a team working on remains once thought too degraded to undergo testing.>> That commitment to making these identifications is as great today in 2018 as it was in 2001.
>> The latest advancements marks a new chapter in a saga that began when two airliners crashed into the Twin Towers of the World Trade Center. The official death toll for which was 2,753. It's also bittersweet for the 9/11 families who fought unsuccessfully to stop the city from making a park out of an enormous landfill in Staten Island where nearly two million tons of debris from that day was dumped.
