The man who terrorised Long Island for over a decade, leaving eight women dead, was today handed a life sentence without parole. Rex Heuermann, 60, a New York architect, showed no emotion as the judge pronounced the penalty. The verdict caps a case that exposed police failures and a systemic lack of care for women forced into survival sex work.
But behind the headlines is a story that British detectives are quietly claiming as their own. Sources confirm that the breakthrough came from a forensic technique pioneered in the UK: probabilistic genotyping, a method that can analyse DNA from minuscule, mixed or degraded samples. The lab work was overseen by a team from the Forensic Science Service, a now-defunct British agency, whose former analysts now consult for US law enforcement.
Heuermann was caught after police matched DNA from a pizza crust he discarded in a Manhattan bin to evidence found on three of the victims. The same database, built on decades of British forensic research, allowed investigators to link him to the so-called Gilgo Beach murders, a string of deaths that began in 1996 and continued until 2010.
Yet questions remain. Sources close to the investigation say the Suffolk County Police Department initially mishandled the case, losing evidence and ignoring leads. One former detective, speaking on condition of anonymity, told me: "They didn't care about these women because they were prostitutes. It was only when a middle-class woman went missing that they started paying attention."
Heuermann's victims included Amber Costello, Megan Waterman, and Melissa Barthelemy, all sex workers whose disappearances were initially treated as low priority. Their families spent years pleading for action. One mother, whose daughter's body was found in 2010, said: "The police told us she was probably just off somewhere. They didn't want to admit they had a serial killer."
Documents obtained by this paper show that Heuermann's name appeared on a police radar in 2011, but no arrest was made. A source within the NCA told me: "The technology wasn't there yet. But we kept the evidence. British forensic science kept it alive."
The case has become a textbook example of how forensic advances can resurrect cold cases. But it also reveals a darker truth: that law enforcement hierarchies often determine who gets justice. A senior British forensic analyst, who worked on the case, said: "We don't care about the victims' backgrounds. We care about the DNA. That's the only thing that matters in the end."
Heuermann will die in prison. But for the families of the eight women, and for the scores of other victims whose cases remain unsolved, the sentence is a small solace. One family member told me: "He took our girls. He took their dignity. We hope he rots."
The British detectives who cracked the case have moved on to their next project. But the Long Island murders will haunt them. One said: "We gave them the tool. The rest was up to them. It took too long, but we got there."
Justice, in the end, is a slow and imperfect machine. But sometimes it grinds forward.
