A New York judge issued a sharp warning to the defense team of accused Gilgo Beach serial killer Rex Heuermann.

Judge Tim Mazzei voiced his exasperation with Heuermann’s attorneys during a Tuesday hearing, as the case has languished in the Long Island courts for more than two years, as reported by the New York Post.

“This trial will commence after Labor Day, no matter the circumstances,” he declared, according to the Post.

The reprimand followed the submission of a fresh batch of motions by Heuermann’s lawyer, Michael Brown, on Monday night, which further contested the evidence in the high-profile murder case, the Post noted.

The new defense filings reportedly challenge roughly 20 search warrants carried out by authorities throughout the investigation, with Heuermann’s attorneys asking to suppress some of the DNA evidence – including a discarded pizza crust and energy drink thrown in the trash – while citing constitutional grounds. 

“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 told reporters, according to the Post. 

In a September ruling, the judge determined the prosecution could use the DNA evidence in the case.

Brown went on to insist his team was not stalling while working on the case, according to the Post.

“We’ve been working hard on this case,” he said. “We will be prepared to try the case come Labor Day.”

On Tuesday, Suffolk County District Attorney Ray Tierney continued to assert that his office would not consider a plea deal for Heuermann, while adding that his team is prepared to go to trial, the Post reported.

“The judge was very explicit, and we are ready,” Tierney said.

However, Tierney reportedly added that he does not believe Brown is intentionally trying to delay the proceedings, insisting that the flurry of new court motions are “the nature of the business.” 

Prosecutors allege Heuermann, 62, was behind the brutal killings of seven sex workers between 1993 and 2010, whose bodies were found throughout remote areas around Long Island. 

Valerie Mack, 24, Megan Waterman, 22, Jessica Taylor, 20, Maureen Brainard-Barnes, 25, Amber Lynn Costello, 27, Sandra Costilla, 28, and Melissa Barthelemy, 24, have all been named as victims in the murders, with Tierney alleging Heuermann is responsible for their deaths.

The cases remained unsolved for decades as the sleepy Long Island community reeled over the possibility of a serial killer lurking in their midst. Heuermann was later arrested outside his Manhattan architecture office in July 2023.

Heuermann’s defense team did not immediately respond to Fox News Digital’s request for comment.

Prosecutors initially charged Heuermann with three of the murders, with DNA evidence later allegedly linking him to four additional bodies. 

Heuermann has pleaded not guilty to the murders and faces a single trial for the seven alleged killings.
