Core Event: New Genetic Genealogy Yields Additional Identifications
Forensic investigative genetic genealogy (FIGG) has enabled the New York City Office of Chief Medical Examiner (OCME) to identify a previously unknown victim of the September 11 attacks, raising the total identified victims to 1,654. The breakthrough follows a 25-year effort that continues to rely on DNA extraction, whole-genome sequencing and iterative retesting of remains recovered from the World Trade Center site.
Background & Context
The attacks claimed nearly 3,000 lives in New York City, including more than 2,800 victims whose remains were recovered from the collapsed towers. Early identification relied on fingerprints and dental records; as those methods proved insufficient for many fragmented remains, the OCME turned to DNA analysis. Advances such as whole-genome sequencing have expanded the pool of potential familial matches, allowing investigators to link distant relatives to unidentified remains.
Data & Statistics
- 2,753 people died in the New York attacks; 60 % have been identified.
- DNA work has produced 1,495 identifications to date.
- The recent FIGG effort added the 1,654th identified victim.
- Approximately 1,099 victims remain unidentified, according to the OCME.
- The site yielded roughly 20,000 human-remains fragments from 17,000 tons of debris.
Official Statements & Responses
Angela Soler, director of forensic anthropology at the OCME, emphasized the promise of the new approach, noting that “there is real promise in using this approach.” She explained that ongoing retesting with emerging technologies is why new identifications continue to emerge years after the attacks.
On-the-Ground Perspectives
Juliette Scauso, whose father Dennis—an FDNY hazmat firefighter—was among the unidentified, says the possibility of identification is both hopeful and painful.
Howard Cash, president and CEO of Gene Codes Corporation, recounts how his team created the Mass Fatality Identification System (M-FISys) to process the massive DNA data set. Their software produced 55 new identifications in its first run, illustrating the critical role of private-sector technology in the public-health response.
Conflicting Reports & Gaps
Both figures are attributed to the OCME, reflecting a range rather than a precise tally.
