After a quarter century of painstaking work, New York City investigators have now identified a second World Trade Center victim using forensic investigative genetic genealogy—a lead-generating DNA technique paired with traditional forensic confirmation—demonstrating how modern genomics can still deliver certainty from the most degraded remains.
At a Glance
- New York City officials announced a second 9/11 victim identification achieved through forensic investigative genetic genealogy (FIGG), with confirmation by the Office of Chief Medical Examiner (OCME).
- The two-stage workflow: genealogical DNA analysis builds an investigative lead; OCME then makes the legal identification through DNA or other forensics.
- The case advances a long-running program to identify remains from the World Trade Center disaster, bringing the formal identification total reported in October to 1,655.
- NYPD’s genealogy unit constructs family trees from public records and permissible databases; OCME performs the accredited laboratory testing and final determinations.
What investigators accomplished—and why it matters
The New York City Mayor’s Office and OCME publicly confirmed that a woman lost in the World Trade Center attacks has been identified through a hybrid approach: investigators first used FIGG to generate a named lead, then OCME validated identity with standard forensic methods that meet courtroom-ready thresholds. This is the second World Trade Center victim identified by FIGG, underscoring that even after years of conventional short tandem repeat (STR) testing, single-nucleotide polymorphism (SNP) profiling and genealogy can surface new paths to kinship when direct matches fail. ABC7 New York and News 12 reported the updated administrative count: 1,655 victims formally identified to date.
That tally reflects a larger truth about mass-fatality science: identification is not a single technology but a system—DNA, anthropology, dentistry, personal effects, and records—coordinated under strict chain-of-custody. In New York, OCME leads that system; the NYPD now contributes a specialized genealogy capability suited to cases where conventional reference matches do not materialize or where DNA is too damaged for routine comparison.
How FIGG fits into the established forensic workflow
FIGG is best understood as a lead engine, not a shortcut to identity. Laboratories convert a challenging sample into a SNP profile (hundreds of thousands of markers, when quality permits). Investigators then compare that profile, under site-specific terms of service, to profiles in permitted direct-to-consumer or opt-in genealogy databases to find genetic relatives—second, third, or more distant cousins. From there, trained genealogists build documentary family trees to converge on likely identities. Crucially, the lead is not the finish line: OCME states it confirms any proposed identity through its own DNA testing or other accepted forensic methods before issuing a formal identification.
That two-stage discipline mirrors best practice across the field. Genealogical inferences can be powerful but are inherently probabilistic until anchored by direct comparison—typically matching the remains’ DNA to a known relative via accredited methods, then applying statistical kinship analysis to reach a reportable likelihood. The approach is laborious, but for the highly fragmented and thermally altered remains characteristic of the WTC site, it expands the space of solvable cases without compromising standards.
Roles and responsibilities: who does what in New York’s model
In the New York framework described in local reporting, NYPD’s genetic-genealogy unit handles the investigative piece: tree-building from public records, civil documents, obituaries, and allowable database matches. OCME, already the nation’s leading mass-fatality identification office after 9/11, maintains custody of physical evidence, develops DNA profiles, and performs the confirmatory analyses that translate a lead into a final identification. That separation of functions aligns with quality-assurance logic: investigative development and laboratory confirmation are distinct competencies with different validations, documentation, and audit trails.
The city has also disclosed program-scale figures that indicate disciplined triage: dozens of potential samples assessed for suitability, with a subset advanced to genealogical analysis where odds of informative matches are highest. Even when FIGG does not immediately resolve a case, the resulting family-tree scaffolding can make the next increment of DNA data—say, a newly accessible relative or an improved SNP recovery—instantly more valuable.
Why 9/11 remains require nontraditional DNA
The WTC recovery produced a uniquely difficult inventory: extreme heat, chemical insults, and fragmentation degraded DNA far beyond ordinary casework. Over the years, OCME and partners have revisited remains with each technical leap—mini-STRs, improved extraction chemistries, next-generation sequencing—squeezing information from samples previously considered unsolvable. FIGG adds a complementary axis: it does not rely on antemortem reference from the exact individual or an immediate family member. Instead, it can exploit distant relatives’ profiles and the geometry of large family networks to find a path back to a name when direct comparison is impossible. Public estimates from the genealogy world underscore the reach of such databases for relative-finding, particularly at the second- to third-cousin range.
That capability is not magic; it’s statistics married to documentation. A single third cousin is not enough. What moves a case is a pattern—multiple matches across distinct branches, converging in time and geography—combined with civil records that resolve non-paternity events, adoptions, and name changes. OCME then applies laboratory rigor to confirm that the remains fit that converged identity through kinship likelihoods or other accepted forensic modalities.
From first to second: what the new identification signals about trajectory
New York’s first FIGG-based World Trade Center identification was announced in August 2026; the second followed in October, indicating a maturing pipeline rather than a one-off success. The cadence matters. Genealogy investigations often run on the order of months, not days; they also depend on the shifting landscape of database participation and methods for recovering SNPs from compromised samples. A string of identifications in close succession suggests process improvements—better SNP capture from damaged DNA, deeper genealogical expertise, and smoother handoffs between NYPD and OCME. It also reflects an enduring institutional commitment to re-examine evidence as science advances, a defining lesson of 9/11 forensic response.
For families, these identifications provide formal resolution—even when, as here, names remain confidential at the family’s request. For the system, they validate the investment in FIGG as an adjunct to, not a replacement for, accredited forensic identification. The key metric is not volume alone but specificity: each identification must rest on a robust laboratory foundation that would withstand technical scrutiny. The city’s public description of the lead-and-confirm workflow aligns with that requirement.

The road ahead: method, governance, and measured expectations
FIGG is expanding nationally as agencies apply it to cold cases and unidentified remains. The technology’s promise is substantial, yet its practice remains deliberately bounded by ethics policies, database rules, and laboratory accreditation. New York’s approach—keeping genealogical lead development distinct from OCME’s confirmatory science—illustrates how to harness FIGG’s reach while preserving the evidentiary integrity of final identifications. Given the scale of the remaining WTC cases, measured expectations are appropriate: not every sample will yield recoverable SNPs or informative relatives, and some family lines resist reconstruction. But the second identification confirms that the runway for progress has not ended; it has been extended by a new, carefully integrated tool.
