New York City investigators have identified a World Trade Center victim using a novel DNA and genealogy technique, marking the first time forensic investigative genetic genealogy has been employed to identify a victim of the Sept. 11, 2001, terrorist attacks. The identification brings closure to a family nearly 25 years after the attacks.
Officials announced Sunday that the adult woman, whose name is being withheld at her family's request, is the 1,654th victim of the 9/11 attacks to be identified. In total, 2,753 people were killed in New York City during the attacks.
The breakthrough was achieved through a collaboration between the Office of the Chief Medical Examiner and the NYPD’s Investigative Genetic Genealogy Squad. This method combines specialized DNA analysis with genealogical research to generate leads, which are then confirmed through forensic testing.
"As we approach the 25th anniversary of the horrific September 11 attacks, we honor the nearly 3,000 people whose lives were stolen that day," said NYC Mayor Zohran Mamdani in a statement. "We remain committed to the families who have spent 25 years waiting for answers."
Forensic investigative genetic genealogy has proven to be a powerful tool in solving cold cases, enabling investigators to trace family connections from DNA evidence and identify individuals who might otherwise have remained unknown. Dr. Graham, the Chief Medical Examiner, stated that this new method could significantly aid the city's ongoing efforts to identify those killed in the attacks.
"This sacred commitment is propelled by our dedication to apply the most innovative scientific techniques," Graham said. "FIGG represents a promising new addition to our toolkit."
Despite this advancement, the work to identify all victims is ongoing. Approximately 1,099 World Trade Center victims, about 40% of those killed in New York City, have yet to be identified. Officials noted that this is the first newly identified World Trade Center victim since August 2025.
