What’s behind the delay in the Rex Heuermann trial ahead of The Gilgo Beach Killer: House of Secrets?


The Gilgo Beach Killer: House of Secrets shifts its focus to a trial that may not happen until 2026. The delay is due to additional charges spanning multiple years, a large volume of evidence, ongoing DNA and device analysis, and pretrial motions that require rulings before jury selection. Court schedules and coordination among agencies also add to the timeline.

Rex Heuermann, a 61-year-old Long Island architect, was arrested in July 2023 and charged with several murders connected to Gilgo Beach. In 2024, prosecutors filed more charges that date back to the 1990s. He has pleaded not guilty and remains in custody.

Recent re-airings of The Gilgo Beach Killer: House of Secrets on Oxygen have attracted new attention, while new filings and lab work keep the case active ahead of a potential trial.

Case background tied to The Gilgo Beach Killer: House of Secrets

Between late 2010 and 2011, investigators found multiple mutilated bodies along Ocean Parkway near Gilgo Beach. The “Gilgo Four” were identified as Maureen Brainard-Barnes, Melissa Barthelemy, Megan Waterman, and Amber Costello.

In July 2023, Heuermann was arrested and charged in three of those killings and later charged in Brainard-Barnes’ death. He has pleaded not guilty, according to NBC News.

Key early evidence included cellphone activity, the use of burner phones, and DNA from a discarded pizza crust that prosecutors say matches a hair found on burlap used to wrap one victim, per CNN.

A co-worker described uneasy encounters that drew attention in coverage, while investigators seized hundreds of items from Heuermann’s home and office as the investigation widened, according to CBS News’ “48 Hours.”


What’s behind the delay in the Rex Heuermann trial

First, the case keeps growing. Each new indictment expands the witness list, lab submissions, and motion practice. This expansion takes time to brief and argue, impacting the court’s schedule, as reported in the 2024 filings by CNN and NBC New York.

Second, discovery is extensive. After the 2023 arrest, authorities seized hundreds of devices and collected a wide range of records, including cell data and digital media. Reviewing the material, producing it for the defense, and litigating its admissibility are step-by-step processes that extend the timeline, according to CBS News’ case review and interviews with investigators and witnesses.

DNA analysis also involves multiple methods, such as mitochondrial and other testing, which require expert reports and hearings before trial, per the same CBS News report (April 12, 2025).

Third, the phone evidence and digital trail require detailed pretrial litigation. Prosecutors have outlined the use of burner phones, search histories, and location records in public filings and press briefings. These items often lead to suppression motions and expert challenges, which courts hear before juries are involved, according to CNN’s charging overview and timeline reporting.

Finally, coordination among agencies is crucial. This case has involved a task force with local, state, and federal roles since the 2022 review that led to the arrest.

Multi-agency evidence chains and multi-year timelines often cause scheduling conflicts for lab access, expert availability, and courtroom time. This helps explain why a firm trial date has not yet been set, as Oxygen has noted while summarizing Heuermann’s current status.
