Gilgo Beach Filing Alleges Rex Heuermann Is Sexual Sadist; Prosecutors Respond

A prosecution filing submitted March 4 in Suffolk County Court describes Rex A. Heuermann as a "sexual sadist" and lays out phone and internet activity prosecutors say links the 62-year-old Massapequa Park architect to contacts with sex workers in the years before his July 2023 arrest. Heuermann has pleaded not guilty to counts tied to the Gilgo Beach murders and has remained in county jail since his arrest.

The filing was filed as a response to defense motions seeking to suppress evidence and to meet a court-imposed deadline, with prosecutors framing the phone logs and search history as part of a broader pattern rather than reliance on a single piece of forensic evidence. Prosecutors say they have more than 150 potential witnesses available should the case go to trial.

Prosecutors allege Heuermann contacted at least 60 sex workers more than 500 times in the period before his arrest. Forensic detail in the filing traces activity to two burner phones: one phone allegedly contacted numbers tied to 56 sex-worker and massage-parlor lines more than 300 times between January 2021 and March 2022; a second phone allegedly remained active until February 2023 and contacted 61 "prostitution-related" numbers more than 220 times. Investigators say those burner phones were kept near a phone registered in Heuermann's name at relevant times.

The filing also catalogs internet activity prosecutors say includes thousands of searches for "hardcore violent pornography" and "images of bruised and impaled women," plus more than 100 searches about serial killers and the Gilgo investigation itself. Prosecutors argue that combination of searches and contacts shows an "absence of mistake" and speaks to intent and proclivity; former prosecutor Vinoo Varghese summarized the prosecution's view: "These show an absence of mistake, that he was using and making these calls, and learning about how to torture people in order to perform these acts upon his victims. So the prosecution's argument is that these are relevant acts. It is also very likely that the prosecution feels that they have an extremely very strong case and are not offering anything short of life in prison."

Defense attorneys have mounted extensive pretrial challenges, including a nearly 180-page filing contesting seizure methods and characterizations of Heuermann. Counsel Michael J. Brown has asked courts to suppress DNA evidence recovered from discarded items, including a pizza crust taken from a Midtown trash can and an energy drink, arguing constitutional concerns: "If our government can go into our garbage can and take our DNA and learn everything about us, what's the purpose of having a Fourth Amendment anymore?" Brown also pressed a novel public-health-law challenge to out-of-state laboratory testing, arguing such testing "criminalizes this very type of action, which is an out-of-state, non-permitted laboratory for profit to test and offer into evidence in the state of New York on a criminal case." After a judge ruled that cutting-edge DNA technology evidence would be admissible, Brown said, "We disagree with the court's decision" and added, "We think the evidence is clear that they didn't sustain their burden."

District Attorney Tierney has defended the handling of forensic testing, saying, "We went through the FBI. We followed all the rules and the mandate." Judge Timothy P. Mazzei has signaled the court's scheduling expectations, saying the trial will begin "right after Labor Day come hell or high water." Heuermann is due back for a status conference on September 23 as pretrial motions remain pending and the case moves toward a trial expected in September.
