The estranged wife of the accused Gilgo Beach killer is battling spreading cancer, her lawyer revealed Friday — as several victims’ families urged the public to ignore a GoFundMe set up to aid her and her kids.

“They are not the victims,” raged John Ray, a lawyer for the kin of some of the slain women, at a Long Island press conference.

Asa Ellerup — the 59-year-old wife of suspected serial murderer Rex Heuermann — has fought skin and breast cancer for several years and needs about 12 to 18 months of further treatment, family lawyer Robert Macedonio said at a separate media gathering.

But the Massapequa Park woman’s insurance will likely run out because she was covered through Heuermann’s architecture firm, which can only pay the premiums for another two months, Macedonio said.

“That’s a big fear and stress on her, on top of all this other stuff that’s going on,” the lawyer said.

But Ray laced into Ellerup for a fundraising effort established on her behalf by Melissa Moore, whose father was known as the “Happy Face Killer” while raping and murdering eight women in the early 1990s. Moore’s dad, Keith Hunter Jesperson, earned the moniker for drawing smiley faces on taunting notes to cops during his heinous rampage.

Moore wrote earlier this month when establishing the GoFundMe account for Ellerup, “The funds are to support Asa and she can direct on what is her highest priority: Basic needs for herself and adult children, to restore the home to whole (as evidence collection damage or destroyed many critical household items), and any other need she may have that is not listed.”

Moore said at the time she needed Ellerup’s endorsement to set up the fund, which she received.

The fund had brought more than $44,650 as of Friday evening.

“The Ellerup family comes forward and says, ‘Help, give us money, look what’s happened to our home, it’s all chopped up,’” Ray said. “Well, let me ask you this: What about the victims who were chopped up? What about the victims who were wrapped up and carried somewhere and dumped?”

He also claimed the family had “plenty of assets” that they could use for Ellerup’s health insurance.

Who were the Gilgo Beach victims?

Suspected serial killer Rex Heuermann — a New York City architect and married dad of two — was arrested in connection with the long-unsolved Gilgo Beach murders. The arrest is tied to the so-called “Gilgo Four,” women found wrapped in burlap within days of each other in late 2010.

The years-long investigation that led to the arrest revolved around the discovery of more than 10 sets of human remains along Ocean Parkway near Gilgo Beach in Suffolk County between December 2010 and April 2011.

Most victims were petite female sex workers with green or hazel eyes. But there were also two exceptions: a 2-year-old girl and a young Asian man.

Melissa Barthelemy, 24

• Barthelemy was a sex worker who lived in the Unionport section of the Bronx and dreamed of one day opening her own beauty salon. She was last seen alive in her basement apartment on Underhill Avenue on July 12, 2009. Heuermann was charged for Barthelemy’s murder in July 2023.

Maureen Brainard-Barnes, 25

• Brainard-Barnes was living in Norwich, Connecticut. She went missing after taking an Amtrak train from New London, Connecticut, to Grand Central Terminal in Manhattan on July 6, 2007. Her remains were found in December 2010. Heuermann was charged for Brainard-Barnes’ murder in January 2024.

Amber Lynn Costello, 27

• Costello, 27, was a sex worker and heroin addict who lived in West Babylon, New York, at a home with a woman and two men. She advertised on Craigslist and Backpage to support her and her roommates’ drug habits. Costello was found on December 13, 2010, after having been last seen leaving her home September 2, 2010. Heuermann was charged for Costello’s murder in July 2023.

Megan Waterman, 22

• Waterman, a 22-year-old mom of one, was last seen on June 6, 2010. She lived in Scarborough, Maine, and earned a living as an escort. She was last seen by her family boarding a New York-bound Concord Trailways bus in Maine. Her body was found on December 13, 2010, on the north side of Ocean Parkway, near Gilgo Beach. Heuermann was charged for Waterman’s murder in July 2023.

Jessica Taylor, 20

• Remains belonging to Jessica Taylor, a 20-year-old woman working as an escort in New York City, were found in a wooded area in Manorville on July 26, 2003. Her additional remains — initially labeled “Jane Doe No. 5” — were discovered on March 29, 2011, along Ocean Parkway.

Valerie Mack, 24

• Valerie Mack was 24 years old and living in Philadelphia when she went missing. She worked as an escort, using the alias “Melissa Taylor.” Relatives last saw Mack in the spring or summer of 2000 in Port Republic, New Jersey, but she was never reported as missing to the police. Her partial skeletal remains were found in Manorville in September 2000 but were initially known as “Jane Doe No. 6.” More bones were found on April 4, 2011, along Ocean Parkway.

Unidentified Asian man

• The skeletal remains of a yet-to-be-identified Asian man were found along Ocean Parkway on April 4, 2011. It is estimated that the man was between 17 and 23 years old at the time of his death. He was approximately 5 feet 6 inches tall with bad teeth.

‘Peaches’ and her daughter

• An African American woman’s partial remains were discovered in Hempstead Lake State Park back in 1997, and she had become known as “Peaches” because of a bitten tattoo of a peach on her left breast. On April 4, 2011, police uncovered the remains of a toddler, who was about 2 years old at the time of her death. DNA testing confirmed that one of the skeletons was that of the 2-year-old girl’s mother, “Peaches.”

Karen Vergata

• A victim previously referred to as Jane Doe No. 7 has been identified as 34-year-old Manhattan woman Karen Vergata. Vergata is believed to have disappeared around Feb. 14, 1996; two months later, her legs were found in a plastic bag at a park near Fire Island’s Blue Point Beach. At the time of her disappearance, Vergata was believed to have been working as an escort. Two sets of Vergata’s remains were identified in August 2023.

Shannan Gilbert, 23

• Gilbert was a Craigslist escort who lived in Jersey City, traveled with her driver Michael Pak from Manhattan to meet a client, Joseph Brewer, at his home in the Oak Beach Association on the morning of May 1, 2010. She spoke with two neighbors before disappearing. Her body was discovered in a marsh near Oak Beach — about half a mile from where she was last seen alive — on December 13, 2011.

Jessica Taylor, 20

• Taylor, a 20-year-old woman working as an escort in New York City, were found in a wooded area in Manorville on July 26, 2003. Her additional remains — initially labeled “Jane Doe No. 5” — were discovered on March 29, 2011, along Ocean Parkway.

Sandra Costilla

• Costilla was murdered in 1993 but had not been included among the so-called Gilgo Beach victims — until now. Investigators suspected convicted serial killer John Bittrolff in Costilla’s death, but he was never charged in her slaying — which remains one of several unsolved Long Island murders.

Ellerup and her two children — Christopher Sheridan, 33, who has special needs; and Victoria Heuermann, 26 — only returned to their home last week after Heuermann’s July 13 arrest for the murders of three women. He is the prime suspect in a fourth.

All of the bodies, along with seven others, were found dumped along the marshy shoreline a few minutes from the family’s home.

Ellerup has told The Post her husband’s shocking arrest has been a heavy burden for the family to bear. Her kids cry themselves to sleep at night, she said, and she wakes up shivering in the night, rife with anxiety.

But she is trying to pick up the pieces – even though her shattered home was tossed upside down by investigators on a nearly two-week crusade to find evidence of her husband’s guilt.

“I said, ‘We’re together,’” Ellerup recalled telling their children. “‘That’s really what matters right now. That you and me are sitting here together and we will get through this.’”

Macedonio, her lawyer, dismissed Ray’s criticism of the family.

“Johnny Ray is trying to keep himself relevant in this case,” Macedonio said. “He’s been on TV for the last 10 years trying to get any kind of press he can to make himself relevant.”

Macedonio also described the damage authorities had done to the family’s home.

“It was piled floor to ceiling with debris that was just taken out of the attic,” the lawyer said. “The children and Asa were sleeping on foam mats on the floor next to the dog.”

A clean-up crew brought in 20-yard dumpsters to clear out the mess, he said.

The family has also filed a notice of claim – a prerequisite to a lawsuit – over the damage police wrought in their home, according to Vess Mitev, the lawyer representing the kids.

Macedonio said the family’s camp still isn’t sure which agencies are responsible for wrecking the house. But their lawyers may pursue legal action when they know.

Macedonio also said the “soundproof room” cops reportedly found in the unfinished basement was just a ceiling-less space with a safe door where Heuermann allegedly stored his scores of guns.

“It is not a soundproof room, it is not a vault,” Macedonio said.

And the creepy, child-sized, fair-haired doll that authorities pulled from the alleged killer’s home was, in fact, a collectible that Ellerup had for “many, many years,” according to the lawyer.

He added that the family has not discussed the case with Heuermann himself.

Ellerup – who the lawyer repeatedly said is not a suspect – also hasn’t visited her husband in jail.

“The only thing his family knows about these charges is what’s been reported in the media,” Macedonio said. “They have not addressed it with him.”
