Twenty-five years after the September 11 attacks, the New York City Medical Examiner's Office continues its mission to identify victims and provide closure to families. As of now, 1,099 victims killed at the World Trade Center, approximately 40% of the total 2,753 deaths there, remain unidentified. The meticulous process of identifying nearly 7,000 recovered human remains, some as small as a fingernail tip, stands in stark contrast to the overwhelming chaos experienced in the immediate aftermath of the tragedy.

Detectives who worked in the morgue in the days following the attacks, many with prior experience in homicide cases, described the scene as unprecedented. "It was constant," recalled retired Detective Lou Savarese, who worked 12-hour shifts for 53 consecutive days. "Once we finished working on one, another body bag was placed on the table and we went to work." Savarese noted that many victims were crushed under tons of concrete, and their remains were often severely fragmented. He also spoke of the emotional toll, stating, "People say never forget. Of course I never will, but I also say never forgive the terrorist who killed thousands of innocent people. They’re cowards."

In the initial days, efforts focused on identifying victims who were recognizable or carried identification, such as wallets or first responder badges. For unidentified remains, DNA samples were collected and meticulously cataloged. "Then we started to get bags just with body parts," said retired homicide Detective Terry Murnane. "Sometimes you would get an arm, sometimes a leg or a hand. Whatever part we got, we treated it as if it was a full body." He added, "I knew a lot of those people would never be identified," reflecting on the missing person fliers that families posted throughout the city. "I knew this was an important job that has to be done. A lot of families were looking for answers."

The recovery process also involved the traumatic identification of fallen colleagues. Retired Port Authority Lt. John Ryan recounted the difficult experience of processing the remains of officers he knew, including Captain Kathy Mazza and Chief James Romito. "I knew every one of those six office officers. That was a rough day," Ryan said. "As we escorted them into the morgue, I thought about each of them—When they were alive and how good they were as cops and, more importantly, as great people. But I had to get back to the site because more bodies needed to be found."

Recent advancements have aided the identification process. In the past year, four individuals have been identified, including one woman whose DNA was matched using forensic investigative genetic genealogy. Despite these advancements, some families, like that of Katherine Wolf, who was on the 97th floor of the North Tower, hold little hope for identification. Charles Wolf, who became a vocal advocate for 9/11 victims' families, has found solace in knowing his wife likely died instantly rather than suffer. The Office of the Chief Medical Examiner (OCME) has committed to continuing its work, a promise made by former Chief Medical Examiner Dr. Charles S. Hirsch and upheld by current staff, many of whom are new to the field but dedicated to the ongoing mission.
