Rex Heruermann's brutal crime - A detailed case overview ahead of The Gilgo Beach Killer: House of Secrets

The Gilgo Beach Killer: House of Secrets returns to TV with a re-air that revisits a case tied to Long Island’s most publicized serial homicides. This article condenses the allegations made by officials about Rex Heuermann, the charges he faces, and what new viewers can expect to see when the three-part series airs again.

The re-air begins Sunday, August 31, on Oxygen, then continues Monday, September 1. Episodes also stream on Peacock Premium and Peacock Premium Plus.

Case facts before The Gilgo Beach Killer: House of Secrets

In December 2010, police searching the Ocean Parkway corridor near Gilgo Beach found four women, later called the “Gilgo Four.” More remains surfaced in March and April 2011 in Suffolk and Nassau counties. The investigation stretched across years.

In July 2023, Suffolk County authorities arrested Manhattan architect Rex Heuermann and announced initial murder charges tied to three victims, with a fourth case named in court filings soon after, according to The New York Times (July 14, 2023). Heuermann has pleaded not guilty.

In 2024, prosecutors added more counts involving earlier victims. These filings extended the timeline back to the 1990s and to sites beyond Gilgo Beach, according to CNN. By December 2024, another indictment added the 2000 killing of Valerie Mack, as reported by NBC.

Evidence and charges around Heuermann before

Court records describe several strands of evidence. A witness description of a first-generation Chevrolet Avalanche pointed investigators to a truck registered to Heuermann. Phone analysis linked burner numbers used to contact victims with locations tied to Massapequa Park and midtown Manhattan.

Investigators also cited “taunting” calls made from a victim’s phone in 2009 near Midtown sites. DNA testing compared a hair recovered from burlap wrapping to DNA taken from a discarded pizza crust, with results prosecutors say are consistent with Heuermann’s profile, according to CNN (June 6, 2024) and NBC News (July 14, 2023).

Additional filings describe mitochondrial DNA consistent with hair from Heuermann’s household found on or near several victims, with prosecutors stating the family was out of state when key crimes occurred and proposing secondary transfer as a possible path, according to CBS News’ “48 Hours” report updated in 2025 (April 12, 2025). Heuermann remains held as the cases move toward trial. He maintains his innocence.
