Suffolk DA Ray Tierney shoots down talk of plea in Gilgo Beach case

Suspected Gilgo Beach serial killer Rex Heuermann has not been offered any plea deal, Suffolk County DA Tierney said Tuesday — adding the probe into other potential victims will resume once he’s convicted.

Heuermann, 61, is already charged in the deaths of seven sex workers whose remains were among nearly a dozen mutilated bodies dumped along a desolate stretch of Long Island between 1993 and 2010.

“We’ve got the charged murders, which is an ambitious case,” the district attorney told The Post. “So first things first, let’s do that. And then we’ll prepare the case for trial, and once that process is completed, we’ll re-evaluate and go back to investigate.”

Asked about rumors of a possible plea deal for Heuermann, Tierney shot back: “No!

“There has been no specific talk with regards to any final disposition of this case,” he said.

Heuermann was arrested in July 2023 outside the Manhattan office of his architecture firm — partly thanks to DNA he left on a tossed-out pizza crust.

He was initially charged in the murder of three sex workers who were among the missing women known in the region as the “Gilgo Four.” Their deaths had gone unsolved for more than a decade.

Prosecutors eventually used DNA evidence to link him to seven victims in all: Valerie Mack, 24; Melissa Taylor, 20; Megan Waterman, 22; Melissa Barthelemy, 24; Maureen Brainard-Barnes, 25; Sandra Costilla, 28, and Amber Lynn Costello, 27. They were sex workers in the New York metro area.

Tierney has not ruled out Heuermann’s possible link to the other discovered victims but said he put the brakes on further investigation after seven because of the state’s cumbersome court disclosure requirements, which he said threatened to delay the trial indefinitely.

Prosecutors are required to provide defense lawyers with all of the evidence in a case, material that is known as “discovery” meant to ensure defendants are not blind-sided in court.

“We really put a moratorium on our investigation of the case because what would happen is we would continue to investigate the case and then we’d have to continue to provide that discovery,” he said.

“We would almost be in this loop,” he said. “So what we’ve done is we’ve really stopped that, and we’re not generating any more discovery just so we can comply with our requirements under the law.”

The Gilgo Beach case has captivated the nation and was the subject of a recent Peacock three-part series that includes exclusive interviews with Heuermann’s wife, Asa Ellerup, and his grown daughter, Victoria Heuermann.
