Investigators have successfully identified a second victim of the 9/11 World Trade Center attack using cutting-edge investigative genetic genealogy, offering renewed hope for families of the still-unidentified.
New York City officials announced the identification of a second victim from the 9/11 World Trade Center attack, a woman whose name is being withheld at her family's request. This breakthrough marks the second successful identification of a WTC victim using advanced investigative genetic genealogy, a technique that compares a victim's genetic profile with public ancestry databases. This same innovative technology was instrumental in identifying Gilgo Beach serial killer Rex Heuermann. The NYPD's specialized genetic genealogy squad conducts the meticulous research, sometimes tracing family histories back hundreds of years. The process involves notifying the medical examiner's office once a potential ID is confident, who then contacts the families, often to their surprise and eagerness for details. Despite the harsh conditions at Ground Zero, which made DNA extraction difficult, the ME's office has collected 47 new genetic samples, providing hope for the 1,098 victims still unidentified. Officials, including Suffolk County District Attorney Ray Tierney, have praised the technology, which also played a crucial role in collecting DNA evidence against Heuermann in 2025 (as stated in the article, likely a typo for 2023 or similar).
