A horrific chapter in Long Island’s history will come to an end as the alleged Gilgo Killer was expected to plead guilty to a series of grisly murders that riveted the public for more than a decade.
Reports indicate that Rex A. Heuermann, a former architect from Massapequa, was expected to change his plea on April 8 before Judge Timothy Mazzei in Riverhead.
Following the court appearance, Suffolk District Attorney Ray Tierney, whose Gilgo Task Force finally cracked the case shortly after he took office, was expected to address the media at a news conference at the Suffolk County Police Academy, relocated to accommodate intense national attention.
The plea would mark a stunning turn in a case that has gripped the region since the discovery of four victims along Ocean Parkway near Gilgo Beach in 2010. Heuermann has been charged in the deaths of eight women spanning from 1993 to 2009.
Officials said family members of the victims were advised to expect the plea change. Details of any agreement had not been publicly disclosed as of press time.
The investigation, led by a multi-agency task force including the Suffolk County Police Department, New York State Police and the Federal Bureau of Investigation, relied on advanced forensic techniques, including DNA analysis, cellphone data and digital evidence.
Prosecutors have alleged the killings occurred over years when Heuermann’s family was away, with several victims discovered along Ocean Parkway and others in wooded areas of Manorville and elsewhere on the East End.
Heuermann was arrested in July 2023 outside his Manhattan office after investigators linked him to a vehicle seen with one of the victims and later obtained DNA evidence. Authorities said he was taken into custody as quickly as possible to prevent him from committing any further crimes, which he had allegedly detailed in a “Murder Manifesto” found on his personal computer.
If entered, the guilty plea would bring long-awaited answers to victims’ families and close one of the most haunting criminal cases in Long Island history.
