Rex Heuermann’s Chilling Four-Day Killing Ritual Revealed in Latest Peacock Documentary on Gilgo Beach Serial Killer

New details about the Gilgo Beach serial killings have emerged from a Peacock documentary that delves into the disturbing rituals of convicted killer Rex Heuermann. The series, titled The Gilgo Beach Killer: House of Secrets, reveals how Heuermann maintained a four-day pattern in the murders of eight women between 2007 and 2010, according to his own account shared during therapy sessions featured in the documentary.

In episode four of the documentary, Heuermann describes a methodical process that began with building trust with his victims, followed by luring them to his Long Island home where he would murder them in a basement area referred to as a “kill room.” After the killings, he reportedly spent a day with the bodies before transporting and disposing of them along Gilgo Beach and nearby areas, using a stopwatch to time and refine the dumping process. The fourth day was reserved for addressing any unexpected developments in the sequence.

The documentary includes interviews with Heuermann’s estranged wife, Asa Ellerup, and their children, Victoria and a son, who speak publicly for the first time about their attempts to understand the allegations against him. Ellerup described her reaction when investigators first questioned her about the Gilgo Beach case, saying she had heard of the murders but initially doubted their connection to her husband.

Heuermann pleaded guilty in Suffolk County Court on April 8, 2026, to seven counts of murder and admitted responsibility for the death of an eighth woman, Karen Vergata, though he will not be charged in her case. As part of the plea agreement, he accepted a sentence of life in prison without parole, along with three consecutive life sentences and four terms of 25 years to life, with formal sentencing scheduled for June 17, 2026.

The victims identified in Heuermann’s confession include Melissa Barthelemy, Megan Waterman, Amber Lynn Costello, Maureen Brainard-Barnes, Jessica Taylor, Sandra Costilla, Valerie Mack, and Karen Vergata. Their remains were discovered between 2010 and 2011 along the Oak Beach and Gilgo Beach corridors of Long Island’s South Shore, sparking one of the most extensive investigations in New York State history.

Law enforcement officials have linked Heuermann to the crimes through digital evidence, including phone records and online activity that placed him in contact with the victims, many of whom were engaged in sex work and advertised their services on websites such as Craigslist and Backpage. Investigators also recovered burlap and plastic materials consistent with those used to wrap the victims’ bodies from storage units rented under Heuermann’s name.

The Peacock documentary, released in three parts in June 2025, was produced with access to Heuermann’s family and includes archival footage, police reports, and therapy session audio. It aims to explore not only the mechanics of the crimes but also the psychological and familial impact of living with someone accused of such acts.

As of April 2026, Heuermann remains incarcerated at the Suffolk County Correctional Facility in Riverhead, New York, awaiting sentencing. Legal proceedings continue to focus on the formal imposition of his sentence, which is expected to affirm the terms of his guilty plea.
