Accused Gilgo Beach serial killer Rex Heuermann contacted dozens of sex workers hundreds of times in the years before he was arrested for allegedly murdering seven women, prosecutors revealed in court filings.

That was among the details that emerged when Suffolk County District Attorney Ray Tierney’s office filed on March 3 prosecutors’ 122-page response to a defense motion to suppress evidence in the case. Among the details that emerged was the fact that the 62-year-old architect from Massapequa Park allegedly used a disposable cell phone — known as a burner phone — to contact“at least” 60 sex workersbetween 2019 and 2023, when he was charged.

“The significance of the defendant’s recent use of burner phones to patronize sex workers cannot be dismissed,” prosecutors stated in the court documents.

Tierney had previously acknowledged that Heuermann was still allegedly contacting sex workers after he was identified as a suspect in 2022 and before he was apprehended, but exactly how many sex workers was not previously disclosed. The district attorney had said these communications made investigators concerned that the suspected serial killer could kill again before authorities had secured the evidence they needed to take him into custody.

Much of the information in the motion was previously released, such as details of a planning document that investigators say they found on the suspect’s computer mapping out his alleged murders, a list of his internet searches about the case — including prior coverage of the casein thePress— and his collection of newspaper clippings about the discovery of the victim’s remains.

Heuermann has pleaded not guilty to killing the four women known as the Gilgo Four — Megan Waterman, Maureen Brainard-Barnes, Amber Lynn Costello, Melissa Barthelemy — as well as Valerie Mack, Jessica Taylor, and Sandra Costilla between 1993 and 2010. His attorney could not immediately be reached for comment.

The next pre-trial conference in the Gilgo Beach Killer

case is scheduled for March 17 in Suffolk County court. Judge Timothy Mazzei has said that he wants the case to go to trial “right after Labor Day.”
