New footage reveals disturbing details as Rex Heuermann admitted to his ex-wife, Asa Ellerup, that he murdered eight women, often inside their family home while they were away.

Chilling Confession Revealed

In a series of revelations set to air on the upcoming NBC Peacock documentary titled The Gilgo Beach Killer: House of Secrets, Asa Ellerup, the ex-wife of convicted serial killer Rex Heuermann, has provided a harrowing account of a face-to-face confrontation with her former spouse.

Details of the Encounter

During this encounter, which took place following his arrest, Heuermann reportedly admitted to a spree of murders that spanned nearly two decades. Ellerup described the atmosphere as tense, noting Heuermann initially appeared nervous before reverting to a cold demeanor.

A Clinical Detachment

The exchange was marked by a clinical detachment, with Ellerup intentionally distancing herself emotionally by referring to her ex-husband as “Mr. Heuermann,” a formality he reportedly mocked. Heuermann calmly confessed to taking the lives of eight individuals.

Murders in the Family Home

The most disturbing aspect of the confession, as recounted by Ellerup, centers on the location of the crimes. Heuermann allegedly confirmed that the majority of his murders were committed within the basement of the family home in Massapequa Park, Long Island. He coordinated these activities to occur only when his family was absent.

Ellerup's Reaction

Ellerup expressed that she had to mentally barricade herself during the confession, building a wall to process the horrific reality of her ex-husband’s actions. She lived with a calculated predator for thirty years.

Guilty Plea and Victims

This documentary’s arrival coincides with recent legal developments in Suffolk County, where Heuermann officially pleaded guilty to multiple counts of murder. The 62-year-old architect admitted to the deaths of seven women found near Gilgo Beach and acknowledged responsibility for an eighth victim, Karen Vergata.
