Gilgo Killer's Family Confesses Horrors
23 Apr
Summary
- Rex Heuermann confessed to killing eight women.
- His ex-wife and daughter heard his confessions.
- Heuermann killed victims in his home, mostly.
The Peacock docuseries "The Gilgo Beach Killer: House of Secrets" concluded by revealing Rex Heuermann's family's reactions to his guilty plea for eight murders. Heuermann pleaded guilty on April 8, 2026, admitting to killing seven women and an eighth, facing life sentences without parole.
His ex-wife, Asa Ellerup, and their daughter, Victoria, underwent therapy sessions where Heuermann confessed to the killings. Ellerup recounted his extreme nervousness and confirmation that he killed eight women, mostly in their home, with Sandra Costilla being the first and killed in his car before he married Ellerup.
Victoria Heuermann described the humiliation and confusion following her father's arrest. She shared her father's confession of killing eight women, claiming the first murder was unplanned but later ones were planned. He attributed his actions to "demons" and a "sickness."
Therapist Alison T. Winter suggested Heuermann planned his killings, detailing a four-day process for preparing, killing, cleaning, and dealing with emergencies. He reportedly stopped killing in 2010 due to a lack of gratification and fear of being caught, especially after Shannan Gilbert's death gained media attention.
Ellerup revealed that Heuermann dismembered bodies in their basement, a room she has since moved into. She continues to process his confession, seeking to understand his motives and triggers, haunted by the brutal truth and expressing that true justice may never be found.
