Two decades after the Twin Towers fell, New York City is still working quietly and painstakingly to identify the remains of those who died. The ongoing effort to match World Trade Center human remains to victims through advanced DNA testing is both a scientific undertaking and a deeply human promise kept. In a tragedy where so many lives ended in an instant, the mission to restore names to anonymous fragments is one of the most enduring legacies of September 11.

Of the 2,753 people killed at the World Trade Center, more than 40 percent remain officially unidentified. That means the families of 1,106 victims still do not have confirmed remains to bury or mourn. For many of them, the lack of physical proof has prolonged a painful uncertainty. As the article describes, it can feel like loved ones simply vanished, leaving relatives suspended between hope and grief.

New York City’s Office of Chief Medical Examiner began this work in 2001, in the immediate aftermath of the attacks. Early on, the process was grueling. Human remains had been exposed to fire, moisture, and weeks of shifting rubble, all of which damaged or degraded DNA. Technicians worked with bone fragments sometimes no larger than a Tic Tac. At the time, they relied on tools like mortars and pestles to grind bone by hand in hopes of finding enough genetic material to test.

In the first years, hundreds of identifications came relatively quickly. Families received names, remains, and at least a measure of certainty. By 2005, though, the pace slowed significantly. The cases that remained were the hardest ones. DNA in these samples was often too damaged for the methods available then. It was not clear how many more lives could be identified or how long the work could continue.

What has changed over the last 20 years is the power of the technology. The article notes that laboratory techniques today use tools like ultrasonic vibration and liquid nitrogen to break down bone in far more precise ways. This allows scientists to reach genetic material that earlier efforts could not access. The methods are more sensitive and better suited to highly compromised samples, which is critical given the condition of the 9/11 remains.

Despite those advances, the scale of the challenge is enormous. The medical examiner’s office holds more than 22,000 samples in its repository. Many of these fragments belong to individuals who have already been partially identified, so a new match might confirm yet another piece of the same person. Even with improved tools, it is possible that some victims will never be matched conclusively to remains. As one assistant director in the medical examiner’s office explains, extracting usable DNA is only half the battle.

Yet even a single new identification can have a profound effect. The team is engaged in difficult, meticulous work that often yields no clear result. When they do succeed, the confirmation can renew a sense of purpose. One official who rushed to the Twin Towers on the day of the attacks described how each positive identification “breathes energy into the team,” reinforcing the importance of continuing the mission “for as long as it takes.”

Recently, that mission resulted in the identification of two more victims of the World Trade Center attacks. The article highlights the cases of Dorothy Morgan, an insurance broker for Marsh & McLennan, and a man whose family requested anonymity. Their remains are the 1,646th and 1,647th identifications made since 2001. Morgan’s remains were first recovered in 2001, while the unidentified man’s remains were recovered across several years in 2001, 2002, and 2006.

These identifications are more than technical successes. They are moments that reopen long-shelved grief for the families involved. Dorothy Morgan’s daughter, Nykiah, shares how the news arrived at her Long Island home when two detectives came to her door in August 2021. For twenty years she had lived with the belief that her mother might have survived somehow. She imagined scenarios in which her mother suffered amnesia, was treated at a hospital, then went on to live a quiet, happy life somewhere else.

Because of this, Nykiah could not even bring herself to fully acknowledge the date of the attacks. For years it felt like September 11 simply did not exist. She recognized September 10 and September 12, but not the day in between. The absence of confirmed remains left room for fragile hope, however improbable. Receiving DNA confirmation that her mother died in the North Tower forced her to face the finality of the loss.

When the detectives told her that her mother’s remains had finally been identified, it triggered what she describes as an emotional roller coaster. On one hand, she now has what many grieving families say they need: indisputable proof. On the other, that proof revives the sorrow of a day she had tried not to relive. She had to make decisions about what to do with the remains of someone who had died twenty years earlier, a task that feels like reopening a wound just as it had begun to scar.

On the 20th anniversary of the attacks, Nykiah planned to visit Ground Zero for the first time. There she would join other families and read her mother’s name aloud at the memorial. For her, and for others who receive similar calls, the work of the medical examiner’s office reshapes how they mark the day each year. It turns an abstract loss into something concrete, painful, and real, yet also offers a form of closure that was not previously available.

City officials, including Chief Medical Examiner Dr. Barbara A. Sampson, have repeatedly framed this effort as a solemn promise. Sampson notes that twenty years ago the office vowed to do “whatever it takes for as long as it takes” to identify victims of the World Trade Center. With each new match, they see themselves continuing to honor that “sacred obligation.” They express hope that newer, more sensitive DNA analysis will lead to additional identifications, even if the work stretches far into the future.

In many ways, this ongoing mission to identify 9/11 human remains reflects how the impact of that day has not ended. The attack itself lasted hours. The grief, recovery, and search for answers have lasted decades. Advanced DNA testing has become a bridge between the physical realities of Ground Zero and the emotional realities of the families who lost someone there. It cannot undo the tragedy or fully heal the wounds, but it can restore names to the unidentified and give loved ones the certainty to mourn.
