Rex Heuermann’s ex-wife says he confessed to her that he killed some of the Gilgo Beach victims inside their Nassau County home.
Asa Ellerup revealed the bombshell details in a teaser of a new episode of a documentary series about the killings.
Ellerup says shortly before he pleaded guilty, Heuermann admitted to her that seven of the eight women were murdered inside the Massapequa Park house.
Those killings took place in a room in the basement of the 1st Avenue home. Ellerup explained in a trailer for the final part of the Peacock series.
We know from evidence shared that there was a massive soundproof vault-like room found.
The former wife of the confessed serial killer also said he told her the eight women are his only victims.
The full and final episode premieres on Peacock on Thursday.
