Three miles north of Floor Zero, inside a lab with sterilized air and so little humidity that the straightforward act of respiratory parches your throat, Mark Want devotes himself to protecting a vow that turns 25 this yr.
“We made a promise that we might by no means quit,” Want, assistant director on the Metropolis of New York Workplace of Chief Medical Examiner, instructed The Put up of himself and a crew of scientists, technologists and anthropologists that has been working all this time to search out, determine and return stays of 9/11 victims to their family members. “We promised these households that we might proceed to advance the know-how and by no means quit. That dedication is as nice at the moment because it was in 2001.
“I used to be right here then, and am right here now,” Want stated. “I really feel honored to be doing this work. It’s a mission that has outlined my profession.”
The crew, lots of whom are too younger to recollect the horrific assault, use cutting-edge strategies to wring strands of DNA out of tiny bone fragments discovered at Floor Zero and match them to collected profiles. They’ve constructed a library of organic identifiers taken from victims’ private objects, like toothbrushes and combs, within the days days after the 9/11 assault.
Want describes the aftermath of the assault that claimed 2,753 lives as “not solely the biggest forensic investigation in america but in addition probably the most tough” — partially as a result of “jet gas, hearth, water used to place out the hearth, chemical compounds within the constructing and daylight all … all destroy DNA.”
Simply final month, the 1,651st sufferer was recognized. (The particular person’s kin requested anonymity and requested that the sufferer stay unnamed as effectively.) However there are practically 7,000 fragments that Want and his group have analyzed however not but been capable of match.
“We’ve gone again to some bones 10 instances, hoping that new know-how will enable us to search out DNA,” explains Want. “If it’s a really small fragment that we’ve already tried [tech] on, and it now offers us only one probability, we have to ask ourselves if we must always strive now or watch for the know-how to get higher. That’s a giant determination.”
The most recent instrument in his arsenal: Forensic investigative genetic family tree that enables the crew to faucet into genetic banks, create household bushes and monitor down beforehand unknown kin of victims.
“Let’s say we’ve got a DNA profile that doesn’t match something within the [DNA] databank — presumably, that’s as a result of no kin got here ahead,” Want stated, declaring that it may have been on account of oversight throughout an especially irritating interval. “Typically, members of the family thought they gave a DNA pattern however, genuinely, they didn’t.
“We use industrial family tree labs to assist us [get started]. Then we take the forensics in-house so the NYPD genealogist can do evaluation and an investigation. All these clues assist us get nearer and nearer to fixing.”
On Sept. 11, 2001, Want was a criminalist within the Workplace of the Medical Examiner, utilizing science to determine the lacking and resolve crimes. When the planes hit the second constructing, he and his colleagues raced downtown to the World Commerce Middle simply after 9 a.m., whereas each towers had been nonetheless standing.
“Usually, when the hearth is out and every thing is secure, that’s when our crew goes in. However this was all palms on deck — our job was to protect the proof,” he recalled. “We had been to arrange a short lived morgue and keep out of the best way of first responders operating into the buildings.”
When the South Tower got here down, Want was knocked out of his footwear and his Workplace of the Medical Examiner jacket was shredded. That garment and his wristwatch, which stopped ticking in the intervening time of affect, are framed and on show on the lab — inspiration to maintain going.
On Sept. 12, he returned to work. However with fewer than 100 sufferer our bodies absolutely intact, the mortuary obtained used largely for analyzing fragmented stays. “The individuals who may very well be recognized, we obtained them again to their households for correct burials,” stated Want, who was then assigned to gathering DNA from reference samples provided by kin of the lacking.
The method of restoration started instantly.
“We had an anthropologist inform us what had been human bones, what had been animal bones — from the restaurant and from individuals’s lunches … — and which had been 300 years previous, buried beneath the Towers,” Want stated.
Typically a sufferer’s belongings have been recognized even when the particular person has not.
“A firefighter’s helmet was recovered. His title was on it and his quantity. We generated a DNA profile [in case other remnants are found and prove to be a match],” Want recalled. “We returned the helmet to his household, however we’ve got not discovered that particular person but.”
When an individual is discovered and their stays — even within the smallest quantity — are delivered to family members, stated Want, “There’s hugging and crying and the sensation is unbelievable. You may’t flip your again on that.”
Paul Keating can relate. In August 2025, the Floridian was notified that of constructive match for his mom Barbara, who had been aboard American Airways flight 11, which crashed into the North Tower.
“They went by way of the rubble centimeter by centimeter,” Keating instructed The Put up, sounding amazed by all of it. “For the primary time in so a few years she’s right here. [The tragedy] by no means goes away. However any closure is sweet closure.”
Want remembers the plea from a lady recalling her daughter who died within the Commerce Middle assault: “She stated, ‘I don’t have a lot time, and I wish to maintain her as soon as extra earlier than I die.’”
Even a tiny shard of bone would supply closure. “I stated, ‘We work nonstop, each day, however I can’t predict who’s going to be subsequent,’” Want recalled.
“She was, like, ‘I perceive. However are you able to promise me this: After I die, and also you do discover her, are you able to pair her with me? I would like her by my facet.’”
He assured the mom that she may rely on his phrase: “We’re not going to surrender.”
