Daughter of Accused Gilgo Beach Killer Reveals Her Pain in Peacock Documentary

There was a lot of negative publicity about the one million dollars-plus that Rex Heuermann's family reportedly received to share their story about the accused, Gilgo Beach serial killer.

But there was also a lot of humanity that emerged when watching them muddling through the mess of their cluttered home, with evidence of two, lengthy police searches still apparent for the Peacock documentary cameras. At one point, Heuermann's adult stepson, Christopher, buried his face in his mother's shoulder and cried.

"My self esteem and self worth are six feet under," Victoria Heuermann, Rex's only biological child, told the daughter of serial killer BTK during a conversation between the two in Episode Three.

It was a reminder of the brutal scrutiny Victoria Heuermann, now 28, has faced over her artwork and even her appearance since her father was arrested for the serial killings on July 13, 2023.

Prosecutors revealed months later the daughter's hair was found on victim Amber Costello, apparently from household transference. In December 2024, we learned Victoria's hair--from a period when she was a toddler--was also discovered on Valerie Mack, who was killed and dismembered in 2000. Investigators believe Heuermann killed most of the seven women he's accused of murdering inside his Massapequa Park, Long Island basement when his wife, daughter, and stepson were away on vacation.

Victoria Heuermann, pictured as a young girl with her father, said her dad was around “90 percent” of the time, but there was that 10 percent when he wasn’t. (from Peacock).

Victoria Heuermann was working as a receptionist at her father's midtown Manhattan architectural firm when she left work on Thursday evening, July 13. In the docuseries, she recalled telling her dad she would see him at home later.

Instead, Rex Heuermann was surrounded by detectives in suits as he lumbered along Fifth Avenue near 35th Street, presumably on his way to Penn Station for the railroad ride to Massapequa Park.

Victoria Heuermann remembered the banging on the family's front door early the next morning.

"FBI! FBI! Open up," Heuermann said dramatically, as she recalled the pre-dawn raid on Friday, July 14, 2023.

She told the Peacock producers investigators asked her probing questions, inquiring if she had ever been sexually abused by her father. She said nothing of the sort ever happened.

"I think if he's guilty, it's going to be a love/hate relationship," Victoria Heuermann said at one point in the documentary. She revealed she has visited her father just once in the Suffolk County Jail in Riverhead, where "He just seemed like himself, like he always is."

Yet when the final episode concluded, producers noted Victoria Heuermann had reached out to them--one week before the docuseries release--to tell them she now believed her father is "most likely" the Gilgo Beach killer, based on publicly available information.

The amount of evidence released in court affidavits from the office of Suffolk County District Attorney Raymond Tierney has been staggering to process, including an alleged planning document for murdering and dismembering that was extracted from Rex Heuermann's computer. The HK-2002-04 memo referred to apparent dump sites, some of them near Mill Road in Manorville, Long Island.

There were hundreds of searches on various electronic devices and phones related to child pornography and torture porn. Newspaper articles and magazines relating to specific victims in the case were allegedly found in his bedroom, basement, and midtown office.

In the documentary, Heuermann's longtime wife, Asa--who divorced him recently to protect family assets--firmly denies that her ex-husband could be a serial killer.

Asa Ellerup, who was married to Rex Heuermann for 27 years until their divorce, still seems smitten with him and doesn’t believe the charges. (from Peacock).

"That planning document is so Dexter-style, it's absolutely absurd," Ellerup said, making a reference to a popular fictional show about a serial killer.

Then she showed the bathroom that Rex Heuermann had remodeled while she and the children were visiting Iceland for five weeks in 2009, at almost exactly the same time that Gilgo victim Melissa Barthelemy disappeared.

Ellerup and her daughter also pointed out sections of ceiling tile that had been removed in the basement, where push pins may have held up tarp to contain blood while victims were killed. The wife and daughter stood by the steel door leading to Heuermann's gun vault and another, secret room that no one was supposed to enter

A number of veteran reporters who covered the case, myself included, were featured in the docuseries, commenting on the jaw-dropping evidence we've reviewed in the nearly two years since Heuermann was arrested.

One of the most compelling interviews was a sitdown with Rex Heuermann's best friend, David Jimenez, who said he shared Rex's love for guns and conservative politics.

Jimenez recalled visiting Heuermann in Suffolk County Jail.

"I said, 'Rex, this is really bad,'" Jimenez remembered.

Jimenez said he advised Heuermann, "If you did it, confess."

Jimenez said Heuermann appeared to be an "empty shell" of a person at that moment.

"He teared up a little bit, and he started crying," Jimenez told Peacock.
