New details of serial killer Rex Heuermann's sick torture routine inside his basement "kill room" was too much for one relative of his helpless victims to bare.

"I can't!" the woman screamed as Suffolk County DA Ray Tierney began describing Heuermann's monstrous crimes in a Riverhead courtroom where the killer was sentenced to life in prison.

"When he talks about what he needs to dispose of, he talks about props, toys, wood items," Tierney told Judge Timothy Mazzei. "Wood items that he made himself with members of his own family that he kept in his house and he used during the execution of these murders, only to destroy them.

"He's treating this as if it were a sport," the prosecutor said. "The talking of lives as though it were a sport."

Heuermann, who pleaded guilty in April to strangling and dismembering eight sex workers -- all but one in a "kill room" in the basement of his family's Massapequa Park home -- was slapped with three life terms.

The hulking architect killed the women between 1993 and 2010, with the cases unsolved until he was arrested outside his Manhattan office in 2023.

Suffolk County prosecutors said Heuermann kept a meticulous "planning document" on his computer, where he kept gory notes on how to prepare to "hunt" his victims and torture them to death.

The victims, all young and petite sex workers, were discovered in remote areas in Gilgo Beach and in Manorville in 2010 and 2011.

Jasmine Robinson told serial killer Rex Heuermann that she's still haunted by the stomach-turning details of what he did to her cousin 13 years ago.

Robinson, one of 13 relatives of Heuermann's victims to speak before the 6-foot-4 architect was hit with three life sentences, said it will never be over for the families.

"Headless and handless torso -- those words will haunt me," Robinson said.

Taylor, 20, was strangled and dismembered by Heuermann in July 2003, with her remains dumped in Gilgo Beach and Manorville, where they were found in 2011.

The confessed killer pleaded guilty to eight murders in April, in exchange for the life sentence and a deal to cooperate with the FBI for the feds to gain better understanding of the criminal mind.

Also speaking in court was the family of Valerie Mack, 24, who was killed in late 2000.

"You have done terrible things to Valerie's earthly body, but you have not touched her," the slain woman's father, Ed Mack, told the killer in court.

Mack's brother added: "You will reap what you have sown."

Rex Heuermann's family unfairly cashed in on the hulking architect's monstrous killing spree, the aunt of one of his victims maintained in court on Wednesday.

Elizabeth Meserve, the aunt of Megan Waterman, caimed that Heuermann's family were paid "millions of dollars" for their part in a Peacock documentary series on the Long Island murders.

"When I read about this I was both sickened and shocked, and deeply disturbed," Meserve said in court. "These individuals profited from the monstrous acts committed against our loved ones by the demon sitting in this courtroom. This is the kind of world we live in."

The confessed killers wife, Asa Ellerup, and daughter, Victoria Heuermann, were featured in the four-part series about the serial killings that haunted Long Island for more than three decades.

The producers of "The Gilgo Beach Killer: House of Secrets," and Ellerup's attorney have not revealed how much the family was paid for their part, but reports have estimated it at more than $1 million.

Lawyer Robert Macedonio told The Post in April that the family is struggling financially because of IRS liens and the inability to sell their Massapequa Park home, where most of the murders took place.

But Meserve called it obscene.

"A demon tortures and kills our loved ones and his family gets filthy rich off his crimes."

Her niece, who was killed in June 2010 after Heuermann picked her up at a Hauppauge Holiday Inn, was the seventh victim and one of four identified as "The Gilgo Four."

Long Island serial killer Rex Heuermann used homemade "wood items" to torture his victims, Suffolk County DA Ray Tierney said in court Wednesday.

"In his planning document he wrote, if I can hear a bird outside, that means people can hear inside," Tierney said in the Riverhead courtroom. "So, he figured he would have to control the amount of air into the victims to control the noise."

The gory details were too much for one relative of Heuermann's eight victims.

"I can't," the woman said before she was helped out of the room by court officers.

The killer's planning document, found on his computer during one of two searches of his Massapequa Park home, included other meticulous details the the grisly murders of eight sex workers.

Heuermann confessed to killing the women between 1993 and 2010, all but one inside his basement.

"He will tell you that these murders just happened," Tierney said. "But they did not. These murders were meticulously planned out by a psychopath."

Heuermann pleaded guilty in April and was sentenced Wednesday to three life terms.

A disgusted Judge Timothy Mazzei unloaded on Gilgo Beach serial killer Rex Heuermann before delivering multiple life sentences and telling court officers to "get him out of here."

Mazzei asked the 6-foot-4 former architect if he had anything to say before he was sentenced in Suffolk County court for killing eight women.

But when the Gilgo Beach killer started speaking from his seat, the judge scolded him to "stand up!"

“There are no words I can say, but I am responsible for what was said in this room today,” Heuermann said.

“The words I would say have no meaning and I’m going to leave it there at this time,” he added meekly.

Someone from the crowd yelled “Speak up!” before Mazzei unloaded on the killer.

“Mr. Heurmann, as [Suffolk County District Attorney Ray] Tierney said, I know that you’re sorry you got caught,” Mazzei said, barely containing his disgust with the sicko. “I assume that you’re sorry for what you did to your wife and children.

“Are you a little bit sorry for what you did to these poor innocent women – eight women you strangled to death, at least eight women that we know of,” he added. “Are you at least a little bit sorry about that. Yes!?”

Heuermann answered that he was, then stood emotionless as several stone-faced officers hovered near him.

“You’ve been described as a very big man but you’re a disgusting and despicable small man if you’re a man at all and you’re a coward,” Mazzei told Heuermann then delivered his sentence before adding “Get him out of here.”

Rex Heuermann's attorney told reporters claimed the admitted serial killer feels real remorse for killing eight women.

“I saw him express some extreme emotion about what he did,” Brown told reporters outside Riverhead court after the killer was slapped with multiple life sentences for the slayings.

Suffolk County District Attorney revealed the Gilgo Beach killer would most likely be shipped off Long Island by the end of the week.

It's not immediately clear where Heuermann will spend the rest of his days after being sentenced to multiple life sentences -- but it won't be on the island.

“Suffolk wants to be rid of him, and so he's gonna be going quick,” Tierney said.

Suffolk County District Attorney Ray Tierney spoke to reporters outside Riverhead court Wednesday, dismissing the statements Heurmann made before he was sentenced.

“I don’t care what he said, it doesn’t matter what he says,” Tierney said. “What matters is what he did and what he said before he was caught, and as the victims so eloquently detailed, not many good or nice things were said before he was caught."

The DA said investigations would continue about the possibility Heuermann has other victims.

“It just doesn't matter what I think or what I believe. I'm not gonna talk about what I think, because it's irrelevant — it’s about what I can prove,” Tierney said.

Tierney also revealed that Rex’s DNA will be uploaded into COTIS, which will make it easier to see if he may be connected to any other crimes throughout the country.

The grieving daughter of Rex Heuermann victim Maureen Brainard-Barnes finally faced her killer in court.

"I was only 7 years old," Nicolette Brainard-Barns told the hulking serial killer in Suffolk County court Wednesday. "I was a little girl and I needed my mom. Like every sex worker, my mother was an entire human being.

"You make me sick and I don't forgive you," she said.

Heuermann, 62, was sentenced to three life terms after pleading guilty in April to the murders of eight Long Island sex workers, whose families packed the Riverhead courtroom as he learned his fate.

"Rex, I noticed a slight smile," the slain woman's sister, Melissa Cann, told the killer. "There is no honor in this. You're a coward who hid behind a mask. You hunted and murdered to satisfy the darkness within you."

Long Island serial killer Rex Heuermann's lame apology wasn't enough for his victims -- or the judge.

The 62-year-old confessed killer addressed the families of the eight women he murdered between 1993 and 2010 in Suffolk County court on Wednesday.

"I am responsible for all that was said in this room," the Massapequa Park monster said after being berated by more than a dozen of the victims' kin. "The words I would say have no meaning.

"I'm going to leave it there," he said.

"Are you at least a bit sorry for the lives you've destroyed?" Judge Timothy Mazzei asked.

"Yes, I am," the killer anwered.

"I believe you're sorry that you got caught," the judge shot back.

"Look at me while I'm talking!"

Amanda Funderburg demanded in court that Rex Heuermann, the hulking monster who strangled her sister, Melissa Barthelemy to death in 2009, at least look her in the eyes.

Funderburg was just 15 when her sister was murdered in 2009 -- and was forced to endure cruel mocking calls from Heuermann after the grisly slaying.

"I was forced to live with crippling anxiety, depression, PTSD, and destroyed nervous system constantly staring at my phone Funderberg told the confessed killer. "Because of the several times you had called me from my sister's phone telling me she was a whore."

Funderburg was one of 13 relatives of Heuermann's eight victims to speak before he was sentenced.

The cousin of Rex Heuermann victim Jessica Taylor berated the hulking serial killer in a Riverhead courtroom Wednesday, moments before he was hit with three life sentences.

"A million years isn't enough," Jasmine Robinson told Heuermann. "Nothing will ever make this right."

Taylor, the youngest Heuermann's eight victims at just 20, was strangled to death in July 2003, dismembered and dumped at Gilgo Beach and in Manorville.

Heuermann pleaded guilty in April to the eight grisly murders.
