In a shocking admission during court proceedings on April 8, 2026, Rex Heuermann acknowledged his involvement in the murders of eight women. This revelation has sent shockwaves through the community and reopened the painful wounds associated with one of the most notorious serial killer cases in recent memory.
His ex-wife, Asa Ellerup, candidly shared her emotional turmoil surrounding the case in the final episode of the Peacock documentary series “The Gilgo Beach Killer: House of Secrets.” In a haunting confession, she stated that she has been plagued by nightly nightmares, a testament to the enduring impact of the horrific acts committed by her former partner. Ellerup’s testimony draws attention not only to the crimes themselves but also to the personal anguish felt by those connected to Heuermann.
Residing in their Massapequa Park home, where much of the violence occurred, Ellerup revealed that she now sleeps in the basement after undergoing renovations post-arrest. “The brutal truth is that Rex Heuermann said he dismembered the bodies in this room,” she recounted, reflecting on the chilling atmosphere of the location. Through her emotional discourse, she expressed remorse for the victims, declaring, “I am really sorry for what these victims went through.”
The grim details of Heuermann’s confession include his admissions to murdering Melissa Barthelemy, Megan Waterman, Maureen Brainard-Barnes, Amber Costello, Jessica Taylor, Valerie Mack, and Sandra Costilla. He further acknowledged the killing of Karen Vergata, although he has not been formally charged in her case. The remains of these women were discovered between 1993 and 2011, remaining a mystery until Heuermann’s arrest in 2023.
Ellerup conveyed her desire for clarity concerning the motivations behind Heuermann’s actions. “I want to know why Rex killed these women, what his triggers were,” she stated. Since learning about the murders, she has grappled with understanding the dark side of her ex-husband. “Because now I see the evil in him,” she noted poignantly.
The confession reportedly came during a private meeting in August 2025, where Ellerup recalled Heuermann’s visibly anxious demeanour. “He looked nervous, very nervous,” she recalled, summarising the gravity of their discussion. During this intense encounter, she directly confronted him about his violence, to which he responded by confessing to the eight murders.
In startling details, Ellerup shared that Heuermann disclosed the locations where many of the murders took place: primarily in the basement of their home. “He said they were killed in his room downstairs, all except one,” she explained, providing insight into the horrific reality that unfolded within what was once their family home.
Ellerup’s revelations have underscored the invasive nature of Heuermann’s actions, extending beyond his victims to impact his family profoundly. Following his confession, authorities discovered troubling information revealing that he had searched online for articles related to a task force investigating the murders as early as 2022. Even more unsettling was an account of him frequently viewing photographs of his victims and their families online.
As Asa Ellerup continues to process the trauma inflicted by her former husband’s actions, she remains a stark reminder of the far-reaching consequences of violent crime. With her spirits deeply affected, she has been open about her struggle to find peace, acknowledging that “It will never go away. It will follow me for the rest of my life.”
This case highlights not only the tragic losses suffered by the victims and their families but also the profound impact on those who were nearest to the perpetrator. With Heuermann’s guilty plea now on record, many, including Ellerup, are left searching for answers that may never fully come to light.
