The remains of a man killed in the terrorist attack on New York's World Trade Center on September 11, 2001, have been identified almost 16 years after the deadly attacks.
Though the name of the male victim has not been released as of yet, he is the 1,641st victim of the attack to be identified through DNA testing, officials said, according to NBC4. Sixteen years after the attack, the New York City Medical Examiner's Office said it identified one of the victims.
The last positive ID came two years ago in March of 2015.

There are believed to be roughly 21,900 pieces of human remains left at the site, and the efforts to return them to their families and loved ones is still ongoing.
It said new DNA technology helped identify him after previous tests yielded no results.
In some cases, scientists have gone back to the same bone fragment 10 or more times, hoping new technology will provide answers. The remains were very hard to analyse as they were affected by extreme factors such as heat from the jet fuel, and the chemicals involved in the resulting explosion and collapse of the buildings.
Nearly 3,000 individuals were slaughtered in NY, at the Pentagon and close Shanksville, Pennsylvania, in the assaults.
