Rex Heuermann told ex-wife he murdered Gilgo Beach victims at family's home, documentary reveals

NEW YORK (AP) — The man who recently pleaded guilty to New York's Gilgo Beach serial murders told his ex-wife while in jail that he killed most of his female victims in the basement of the family’s dilapidated home, the latest episode of a documentary series shows.

His ex-wife, Asa Ellerup, said in a teaser for the episode airing Thursday on NBC’s streaming service Peacock that Rex Heuermann also told her that the eight women he has admitted to killing were his only victims.

Ellerup says later in the teaser that he told her that he killed seven of them in the basement of the family's house in Massapequa Park on Long Island while she was away.

“I said to him, ‘So Mr. Heuermann, I understand that you are confessing to me on these murders. Can you please tell me how many of these women did you kill’?,” she said in the 90-second clip. “He said, ‘Eight’.”

Ellerup said she intentionally didn’t use her former husband’s first name as a way to “put a wall up” between the two.

“When he started talking, it started feeling like that’s the Rex I know,” she said. “But I didn’t want to see that one. I wanted to see the one I needed to see.”

The latest and last installment of “The Gilgo Beach Killer: House of Secrets” follows the release of the series' first three episodes last June. Another documentary, “Killing Grounds: The Gilgo Beach Murders,” also comes out Wednesday on Amazon's streaming service, Prime Video.

Ellerup's attorney, Robert Macedonio, declined to discuss what other new details are revealed in the new episode of the Peacock documentary.

“This 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,” he said in an email. “Ms. Ellerup would like the focus to remain where it belongs — on the victims and their families, who have suffered immeasurable and lasting losses.”

Vess Mitev, a lawyer for the couple's two grown children, Victoria and Chris, said the two “echo the sentiments of their mother, and wish only to move forward as best they can, given this remarkably dark chapter in their lives.”

Heuermann’s lawyers didn’t respond to an email seeking comment.

Earlier episodes of the documentary showed the family struggling to reconcile their memories of the architect, who had an office in Manhattan, with the portrait of the killer described by authorities.

Ellerup, who divorced Heuermann after his arrest in 2023, steadfastly defended her ex-husband’s innocence during those earlier episodes. But her daughter eventually conceded her father “most likely” committed the brutal killings that bedeviled investigators and drew intense interest from true-crime watchers for years.

The saga came to a close earlier this month when Heuermann, 62, of Massapequa Park, admitted in Riverhead court to murdering seven women and also killing an eighth he had not yet been charged with over a 17-year span.

Heuermann said in court he strangled the women, many of them sex workers, and dismembered some of their bodies before dumping them on a desolate parkway not far from Long Island's Gilgo Beach, some 50 miles (80 kilometers) from Manhattan.

He’ll be sentenced in June to life in prison without the possibility of parole.

WASHINGTON (AP) — Democratic Rep. Sheila Cherfilus-McCormick of Florida resigned from office on Tuesday moments before the start of a hearing that could have led to a recommendation that she be expelled from Congress.

Cherfilus-McCormick was the subject of a more than two-year investigation by the House Ethics Committee, which had determined recently that she had violated multiple federal laws and House rules. Support from her own party was increasingly in doubt.

It's the third resignation in a little more than a week from a House lawmaker. Reps. Eric Swalwell, a California Democrat, and Tony Gonzales, a Texas Republican, announced within hours of each other that they were leaving Congress. Both men were facing sexual misconduct allegations and possible expulsion.

In a statement, Cherfilus-McCormick said the House committee denied her new attorney's request for more time to prepare a defense. She also said she would not pretend that the investigation had been anything other than a “witch hunt,” and rather than play political games, she would resign, effective immediately.

“But let me say this plainly: we should be very careful about the precedent we are setting in this country, we do not punish people before due process is complete," she said. "We do not allow allegations alone to override the will of the people. That is a dangerous patch, and one that should concern every American, regardless of party.”

Cherfilus-McCormick is also facing federal criminal charges accusing her of stealing $5 million in federal disaster funds and using the money to buy items such as a 3-carat yellow diamond ring.

She has pleaded not guilty to the criminal charges and says she is not guilty of ethics violations, either.

The allegations against the congresswoman center on how she received millions of dollars from her family’s health care business after Florida mistakenly overpaid the business by roughly $5 million with COVID-19 disaster relief funds. She is accused of using that money to fund her 2022 congressional campaign through a network of businesses and family members.

Cherfilus-McCormick declined to testify during a previous Ethics Committee hearing, citing her Fifth Amendment right against self-incrimination. Her attorney, William Barzee, sparred with some of the lawmakers and argued that they should have allowed a thorough ethics trial, at which he could present witnesses and evidence to counter the conclusions of House investigators.

A group of supporters in Cherfilus-McCormick's congressional district had weighed in on her behalf with the lawmakers who lead the Ethics Committee, urging committee leaders to proceed with caution in sanctioning her.

“Our communities deserve stability. Our voices deserve to be heard. And our right to representation must be protected,” said one of the letters signed by about a dozen local faith leaders, union officials and others.

Rep. Yvette Clarke, D-N.Y., chair of the Congressional Black Caucus, along with other members of the caucus, issued a statement that praised Cherfilus-McCormick's time in Congress. They said Cherfilus-McCormick “worked to uplift her constituents and elevate issues impacting underserved communities at home and abroad.”

“We extend our appreciation for her service and offer our prayers for her and her family," the caucus members said.

In all, the Ethics panel's more than two-year investigation led to the issuance of 59 subpoenas, 28 witness interviews and a review of more than 33,000 pages of documents.

House Democratic leaders had declined to condemn Cherfilus-McCormick, saying they wanted to see the ethics process play out.

Still, leadership had been in conversations with her for weeks, ever since the Ethics committee released its findings, about the situation and the likelihood of an expulsion vote.

The House has historically been reluctant to serve as the final arbiter of a lawmaker’s career, preferring to give that final say to the voters.

Of the six House members expelled, the first three fought for the Confederacy during the Civil War and were expelled for disloyalty. The next two had been convicted of crimes. The final one was George Santos, the scandal-plagued freshman who was the subject of a blistering ethics report on his conduct as well as a federal indictment.

Santos, a New York Republican, served time in prison for ripping off his campaign donors before President Donald Trump granted him clemency, and he has apologized to his former constituents.

Under the Constitution, at least two-thirds of the House has to vote for expulsion for it to occur, a high threshold that requires enormous bipartisan support.

House Speaker Mike Johnson, R-La., told reporters last week he believed the House would move to expel Cherfilus-McCormick.

“The facts are indisputable at this point," Johnson said.

House Majority Leader Steve Scalise, R-La., took exception to Cherfilus-McCormick's characterization of the Ethics Committee's investigation.

“Well, if you steal money, it's called theft. It's not called a witch hunt, and stealing taxpayer money is not going to be tolerated,” Scalise said.
