Gilgo Beach Serial Killer Rex Heuermann Confesses to Eight Murders in Tense Meeting with Ex-Wife
In a chilling and unprecedented confrontation, Gilgo Beach killer Rex Heuermann sat face-to-face with his ex-wife, Asa Ellerup, for the first time since his arrest and calmly confessed to a string of murders that he revealed took place in the basement of their family home. Newly revealed footage captures the disturbing exchange where Ellerup described walking into the room and immediately sensing something was profoundly different about the man she once knew.
A Nervous Encounter Turns to Unsettling Familiarity
'He looked very nervous - very, very nervous,' Ellerup recalled of Heuermann's initial demeanor. However, the tension quickly gave way to something more unsettling: a strange, almost familiar version of the man she had been married to for nearly three decades. 'When he started talking, it started feeling like that's the Rex I know,' she explained. 'But I didn't want to see that one. I wanted to see the one I needed to see.'
Determined to maintain emotional distance, she addressed him not as her husband, but more formally. 'So Mr Heuermann,' she recalled saying, 'I understand that you are confessing to me on these murders - can you please tell me how many of these women did you kill?' His reply was both immediate and chilling in its simplicity: 'He said eight.'
Calculated Admissions and Horrifying Details
Ellerup confirmed Heuermann showed no hesitation when answering. 'No - he just told me the answer,' she stated. Then came a detail that transformed the conversation from unsettling to horrifying. 'He said I wasn't home during all of them,' she continued. When pressed on where the killings had occurred, Heuermann admitted: 'They were killed in his room downstairs. All except one.'
Heuermann's admission was as calculated as the crimes themselves, calmly describing how he waited until his wife was gone before turning their family home into a killing ground. At one point, Ellerup said she had to mentally shut down to endure what she was hearing. 'Well, I put a wall up,' she explained. Her attorney noted that even the tone of the exchange reflected how far removed the moment was from their former life together. 'She called him Mr. Heuermann,' the lawyer said. 'So his response was, 'Oh, are we formal now? Mrs. Ellerup?''
Decades of Terror and a Dramatic Courtroom Conclusion
Ellerup, who divorced Heuermann after his arrest, has always maintained that she and her children lived in complete ignorance of the crimes. The quiet, clinical exchange is set to air in the final part of a documentary on Peacock detailing the life and crimes of the Gilgo Beach killer, who prosecutors say terrorized Long Island for decades.
Only weeks ago, Heuermann brought a decades-long investigation to a dramatic close. Inside a packed courtroom in Suffolk County, the 62-year-old architect pleaded guilty to multiple murder charges tied to the notorious Gilgo Beach killings - a case that had haunted the region for more than 30 years. He admitted to murdering seven women between 1993 and 2010 and acknowledged an eighth victim for which he had not been formally charged.
Speaking in a flat, almost detached tone, Heuermann confirmed he strangled his victims, many of whom were young women working as escorts. Some were dismembered before their remains were scattered along remote stretches of coastline near Gilgo Beach.
The Victims and the Investigation Breakthrough
The victims, including Melissa Barthelemy, Megan Waterman, Amber Costello and Maureen Brainard-Barnes, became known as the 'Gilgo Four.' Their discovery in 2010 sparked a sprawling investigation that would drag on for more than a decade. Additional victims, including Jessica Taylor, Valerie Mack, Sandra Costilla and Karen Vergata, were later linked to the same killer through DNA and forensic evidence.
For years, the case seemed unsolvable, bogged down by missteps, jurisdictional tensions and a lack of clear suspects. Everything changed in 2023 when investigators quietly zeroed in on Heuermann using:
- Cellphone data analysis
- Witness accounts and testimonies
- Crucial DNA evidence retrieved from a discarded pizza crust
The genetic material matched hairs found on victims, definitively tying him to the killings. Prosecutors said they deliberately kept the investigation secret to avoid tipping him off. 'We wanted the one person who mattered, the murderer, to think it's business as usual,' Suffolk County District Attorney Ray Tierney stated after the plea.
A Double Life Exposed
For decades, prosecutors say, Heuermann lived a double life - appearing as a suburban husband and father on the surface while working as a Manhattan-based architect who returned each night to a quiet suburban home in Massapequa Park. Simultaneously, he was a predator who used his family's absence as cover to lure women into the house and kill them out of sight.
Ellerup's account appears to confirm what prosecutors long suspected: that at least some victims were brought inside the house, into a basement room, where they were killed while his family was away. Prosecutors have stated Ellerup and the couple's children were out of town during the murders and had no knowledge of the crimes.
In court, Ellerup sat quietly as her former husband detailed his actions, at times gripping her seat, at others holding hands with her daughter. After the hearing, she issued a brief statement expressing sympathy for the victims' families and asking for privacy. The family's attorney said their lives had been 'destroyed' by Heuermann's actions.
Closure and Unanswered Questions
For the victims' families, the guilty plea brought a measure of long-awaited closure. 'This has been a long journey of hope - hope that one day we would stand here and say her name with justice beside it,' Melissa Cann, sister of victim Maureen Brainard-Barnes, said after the hearing. Elizabeth Baczkiel, mother of Jessica Taylor, added: 'I am glad that this is over as far as him pleading guilty. It took a big chunk of stress off of me and my family.'
Yet even with the confession, significant questions remain. Investigators believe there may be additional victims beyond the eight acknowledged. Others point to disturbing evidence recovered from Heuermann's home, including what prosecutors described as a 'planning document' outlining how to select, kill and dispose of victims. The search for complete answers continues as the community grapples with the horrifying reality of a serial killer operating undetected for decades in their midst.
