The ex-wife of the man who admitted to killing eight women whose remains were discovered on Long Island's Gilgo Beach claims he told her that seven of those victims were murdered in their Massapequa Park home. 

Rex Heuermann, 62, was charged with the killing of seven women. He pleaded guilty as part of a plea deal on April 8, which included admitting he intentionally caused the death of an eighth woman, according to NBC News. In exchange for his plea, he wasn't charged with the murder of the eighth woman. 

Asa Ellerup, Heuermann's ex-wife, said in a Peacock documentary series about the killings that he told her he killed seven of the women in their home. He also said she was not home during any of the killings. All the women, Ellerup said her ex-husband told her, were killed in his room downstairs "except one." 

Altogether, 11 sets of remains were discovered on the beach.
