The convicted Gilgo Beach serial killer<\/a> who recently pleaded guilty to seven murders confessed to his ex-wife that he had killed multiple women in the basement of their home while she was away, a new documentary reveals.<\/p>\n

In a teaser clip<\/a> released on Tuesday to promote Peacock\u2019s The Gilgo Beach Killer: House of Secrets, Asa Ellerup said her ex-husband, Rex Heuermann, told her he killed eight women without hesitation. That was the case, though he was only formally charged with \u2013 and pleaded guilty to \u2013 seven.<\/p>\n

At an 8 April court hearing in which he pleaded guilty to seven murders during a 17-year spree, Heuermann acknowledged that he murdered one more woman in whose slaying he had not been charged \u2013 but he had not elaborated.<\/p>\n

Ellerup, who finalized her divorce from Heuermann in March 2025 after 27 years of marriage, said in the teaser clip that she refused to address her ex-husband as Rex during the jail cell meeting where he made that admission.<\/p>\n

\u201cSo Mr Heuermann, I understand that you are confessing to me on these murders,\u201d she recalled saying. \u201cCan you please tell me how many of these women did you kill?\u201d<\/p>\n

Ellerup told her lawyer: \u201cHe said he killed eight women.\u201d<\/p>\n

\u201cEight?\u201d he replied. \u201cWho was the eighth? Because he\u2019s charged with seven.\u201d<\/p>\n

Ellerup replied: \u201cI didn\u2019t ask.\u201d<\/p>\n

She said Heuermann told her she wasn\u2019t at their Massapequa home when the killings took place, which investigators have also maintained. The bodies of the missing women, killed between 1993 and 2010, were mostly found in marshes alongside a stretch of Long Island\u2019s beachfront.<\/p>\n

\u201cHe said yes \u2013 they were killed in his room downstairs,\u201d Ellerup remarks on the clip. \u201cAll except one.\u201d<\/p>\n

Investigators searching their suburban home later found a soundproof vault-like room, hundreds of guns and detailed plans for the killings.<\/p>\n

Heuermann \u201cwalked among us playacting as a normal suburban dad when all along he was targeting these women for death\u201d, Suffolk county prosecutor Ray Tierney said after the Manhattan architect confessed to the crimes in court.<\/p>\n

\u201cHe thought that by killing them, he could silence them forever and get away with murder,\u201d Tierney added. \u201cBut he was wrong.\u201d<\/p>\n

Ellerup\u2019s comments were made during the final episode of The Gilgo Beach Killer: House of Secrets, a four-part documentary series. The finale is due to begin airing on Peacock on Thursday.<\/p>\n

Heuermann\u2019s confession to his former wife came soon before he pleaded guilty to killing Amber Lynn Costello, 27; Megan Waterman, 22; Melissa Barthelemy, 24; and Maureen Brainard-Barnes, 25, known as the \u201cGilgo Four\u201d.<\/p>\n

During his 8 April court appearance, he also confessed to the murders of Valerie Mack, 24; Jessica Taylor, 20; and Sandra Costilla, 28; and to the uncharged murder of Karen Vergata, 34, who went missing in 1996.<\/p>\n

In a brief hearing, Heuermann said he used strangulation to kill each of his victims, dismembering some and tying them up in burlap sacking. The crimes were linked to Heuermann, in part, by hairs found on the burlap.<\/p>\n

After her ex-husband\u2019s plea hearing, Ellerup said her thoughts and prayers were with the victims\u2019 families. And she asked for privacy for her own family during what she called a \u201cvery difficult time\u201d.<\/p>\n

Heuermann\u2019s attorney, Michael Brown, said it was his client\u2019s decision to plead guilty because he wanted to spare victims\u2019 relatives and his family from the ordeal of a trial.<\/p>\n

Heuermann is scheduled to be sentenced to multiple terms of life imprisonment on 17 June.<\/p>\n

Ellerup\u2019s lawyer, Bob Macedonio, who also represents her daughter Victoria, said in a statement to the New York Times <\/a>on Monday: \u201cThis has been an extremely emotional and painful process for the family to endure and come to terms with the allegations that Rex Heuermann was the Gilgo Beach serial killer.<\/p>\n

\u201cMs Ellerup would like the focus to remain where it belongs \u2013 on the victims and their families, who have suffered immeasurable and lasting losses.\u201d<\/p>\n
