gilgo beach serial killings Rex Heuermann.

The suspect in Long Island’s infamous Gilgo Beach serial killings has lost his bid to separate the sprawling case involving seven brutal killings spanning decades into multiple trials. Judge Timothy Mazzei ruled Tuesday that the trial against Rex Heuermann would move forward as a single trial. Heuermann’s lawyers argued there was no “unique and consistent modus operandi” common to all the murders. But prosecutors noted the victims were all petite women in their 20s involved in the sex trade. They also said the remains of nearly all of the victims were found in the same location not far from Heuermann’s home.

The daughter of Rex Heuermann, the accused Gilgo Beach serial killer, told a new documentary she believes her father “most likely” responsible. The admission from Victoria Heuermann comes near the end of “The Gilgo Beach Killer: House of Secrets,” a three-part documentary released Tuesday on NBC’s streaming service Peacock. Her mother, Asa Ellerup, is also prominently featured in the documentary and steadfastly defends her ex-husband’s innocence. Heuermann’s lawyer didn’t immediately comment. The Manhattan architect has pleaded not guilty to killing seven women, most of them sex workers, and dumping their bodies on a desolate stretch of beachside road on Long Island.
