Accused Gilgo Beach Killer's Voice Heard In Trailer For Peacock's New Series, Debuting Tuesday

LONG ISLAND, NY — The first glimpse is available for a new three-part series set to debut Tuesday, offering a chilling, never-before-seen look into the life of accused Gilgo Beach killer Rex Heuermann.

A trailer released by Peacock and available on YouTube features shots inside and outside of the home, as well as interviews with Heurmann's ex-wife Asa Ellerup, children and his best friend.

"The question everyone keeps asking is: 'How could you not know?'" Those are the first words of the trailer.

Also, at the end of the trailer, Heuermann's voice can be heard. His voice was only heard once before, in December, when he spoke for the first and only time in court to say: "Your honor, I am not guilty of any of these charges."

In the trailer, Ellerup is speaking on the phone to Heuermann. "Hello," Heuermann says. "How are you doing?" Ellerup asks. "Alright, how are you today?" Heuermann asks. "I'm doing great, now that I've got you on the phone," she said.

"Gilgo Beach Killer: The House of Secrets," is set to debut on Peacock, NBCUniversal's streaming service, on Tuesday, June 10, NBC said.

"After the arrest of the alleged Gilgo Beach killer, this documentary goes inside the suspect's home for the first time, where exclusive commentary from his own family unravels a chilling portrait of a man accused of living a double life and hiding dark secrets under their own roof," a synopsis on the YouTube page said.

Robert Macedonio, attorney for Heuermann's ex-wife Asa Ellerup, told Patch: "I'm looking forward to watching the entire three episodes. There is a lot of never-before-seen footage of the family and the home, detailing the family’s journey from the arrest through the last court appearances."

Executive produced by Curtis “50 Cent” Jackson, "Gilgo Beach Killer: The House of Secrets" is set to explore "the life and aftermath of the alleged killer in three, one-hour episodes. The series goes inside the Heuermann home and meets with the people who know him, shining a spotlight on a violent double life," NBCUniversal said.

The series features executive producers: Curtis “50 Cent” Jackson, David Karabinas, Troy Searer, Colleen Hall, Jamie Lustberg, Melissa Moore, Jared P. Scott, and Brad Bernstein; the series is directed by Jared P. Scott and produced by Texas Crew Productions alongside 50 Cent’s G-Unit Film & Television and New York Post Entertainment, Variety said.

Speaking with Patch, Macedonio said Ellerup's divorce from Heuermann's has been finalized. And, he added, with the house the couple shared "eventually going to be sold" — right now, there is no time frame for the sale, he said — Ellerup is in the process of disposing of some items and putting others in storage.

To that end, recently, a safe door that had once been mounted into concrete cinder blocks, "as part of the basement walls" — behind which was a room where guns were kept on neat gun racks — was recently removed, Macedonio said.

The Peacock series is not the first in recent months to focus on the chilling Gilgo Beach murders. In April, in the midst of a Frye hearing — held to determine the admissibility of nuclear DNA evidence in the trial involving Heuermann — a new documentary on the Gilgo Beach murders debuted on Netflix and soon ascended to a top spot in TV shows.

The Frye hearings are set to commence again on Tuesday, June 17.

According to Netflix, "Gone Girls: The Long Island Serial Killer," debuted and ascended quickly as scores watched. "Young women who worked in the sex industry were disappearing from New York City and Long Island and their families were desperate for answers," a description of the three-part documentary read. "Then in 2010, female remains were found in the Gilgo Beach area of Long Island, leading to a string of additional discoveries at a virtual dumping ground steps away from New York’s busiest beaches. Despite all of this, the case of the 'Long Island serial killer remained unsolved for 13 years — until July 2023, when a major break came after corruption was rooted out within the police responsible for the case."

Netflix added: "From two-time Academy Award-nominated and Emmy-winning director Liz Garbus (Lost Girls) comes the definitive look at the twists and turns in a case that dominated headlines, and is still developing in real time."

In 2020 Netflix also debuted a new movie filmed on the North Fork in 2018 about the Gilgo Beach murder. The film, also directed by Garbus, was based on the book "Lost Girls: An Unsolved American Mystery" by Robert Kolker, according to producer Anne Carey.

Speaking with Patch, Kolker, who is interviewed on camera in the new series, and is credited as a "consulting producer," said he likes the new three-part documentary very much. "I think the series wisely focuses the institutional failures that let a killer roam free for decades, and the persistence and power of the victims’ families."

To date, Heuermann stands charged in seven murders, officials said: In December, Heuermann was charged with the death of a seventh victim, Valerie Mack. In June, Heuermann was slapped with new second-degree murder charges in the deaths of two additional women, Jessica Taylor and Sandra Costilla.

In July 2023, Heuermann was indicted on three counts of first-degree murder charges and three counts of second-degree murder charges in the deaths of sex workers Melissa Barthelemy, Megan Waterman and Amber Costello, whose remains were found along Ocean Parkway in 2010.

Heuermann was also charged with the murder of a fourth woman, Maureen Brainard-Barnes. New DNA evidence helped connect Heuermann to all four of the deaths, said Suffolk County District Attorney Ray Tierney, who is prosecuting the case.

A total of 11 sets of remains were found in the Gilgo Beach murders, which rocked Long Island. The remains included that of a toddler and an Asian male.

Heuermann has pleaded not guilty to all charges.
