Remains of 1,641 victims have been identified.
The city's forensic pathologists said Monday they have formally identified a man who died at the World Trade Center on 9/11.
The man is the first 9/11 victim to be identified since March 2015, when officials announced the identity of Matthew David Yarnell, a 26-year-old resident of Jersey City, New Jersey, who worked on the 97th floor of the south tower.
The medicinal inspector's office has been retesting human stays recouped amid the first recuperation at ground zero, gathered before May 2002.
Almost 16 years after the attacks, some 40 percent of those died - 1,112 people - remain unidentified, the medical examiner's office said. Most of the DNA profiles generated belong to previously identified victims.
It said new DNA technology helped identify him after previous tests yielded no results.
However, during this time, DNA technology has advanced alongside the multi-million dollar effort to try and connect 21,900 found pieces of remains to the lives they represent. Conceivable stays of more than 20 casualties were recuperated.
Investigators were unable to recover scores of bodies trapped in the rubble, and the effects of heat and chemicals like jet fuel have further complicated the identification process.
In New York City, the Twin Towers were hit, the structures engulfed in flames before eventually collapsing, killing more than 2,600 people.
