New York City officials have identified a victim of the Sept. 11, 2001, attacks using a first-of-its-kind genetic genealogy technique [1].
The breakthrough marks the first time forensic investigative genetic genealogy has been used to identify a victim of the World Trade Center attacks. This method allows officials to match remains to living relatives through a combination of DNA testing and family-tree research, offering a new path toward closure for families of the missing.
The identification was performed by the New York City Office of the Chief Medical Examiner and the NYPD Detective Bureau [1]. The individual is the 1,651st victim of the attacks to be formally named [2].
Approximately 3,000 people died in the attacks [4]. Despite the passage of 25 years, nearly 1,100 victims remain unidentified [2]. Traditional DNA profiling often requires a direct sample from a close relative, which may not always be available or provided. Genetic genealogy expands this search by analyzing broader ancestral links to build a biological bridge to the deceased.
Officials said the goal is to formally identify every person killed in the attacks. By integrating genealogy with forensic science, the city can now process remains that were previously considered unidentifiable due to the extreme conditions of the site [1], [5].
The use of this technology comes as the city approaches the anniversary of the attacks this September. The process involves comparing the DNA from the remains against public and private genetic databases to find distant cousins, or other relatives, who can then provide the necessary samples for a definitive match [3].
“The individual is the 1,651st victim of the attacks to be formally named.”
The adoption of investigative genetic genealogy represents a shift in forensic capabilities for cold cases. While traditional DNA testing relies on direct familial matches, this method leverages the growth of commercial genetic databases to identify remains through distant kinship. This success suggests that a significant portion of the remaining 1,100 unidentified victims may eventually be named as the technology becomes more integrated into the city's forensic workflow.
