Gilgo Beach serial killer suspect Rex Heuermann expected to plead guilty today

“First and foremost, it can be an acceptance of responsibility. But also it can be things like not wanting to go through the trial. There can be things that he may not want to put his own family through. It’s hard to know exactly why, but there’s many reasons why defendants decide to plead guilty,” New York Law School professor Anna Cominsky told CBS News New York’s Mary Calvi. 

Watch her full interview here. 

Reporters and press personnel started lining up to enter the court as early as 5 a.m., CBS News New York’s Carolyn Gusoff reported. 

Court opens at 9 a.m. and the courtroom proceedings weren’t expected to begin until 11 a.m. The court process is expected to take about an hour, if not more, once it gets started. 

Then this afternoon we’re expecting to hear from Heuermann’s defense attorney, as well as from Suffolk County DA Ray Tierney and family members of the victims. 

Prosecutors alleged in court documents that Heuermann used burner phones to contact dozens of sex workers hundreds of times in the months leading up to his arrest. 

Heuermann also allegedly conducted thousands of internet searches for “hardcore violent pornography,” prosecutors said. 

They added his search history also includes more than 100 searches about serial killers, and about the Gilgo Beach investigation. 

Former prosecutor Vinoo Varghese previously said all of that would be evidence that shows “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.”

Heuermann is charged in the murders of seven women, dating to 1993. The remains of 11 people were discovered around Gilgo Beach in 2010 and 2011, and investigators believe he may be linked to more killings. 

Rex Heuermann was arrested in July 2023. Prosecutors said hairs connected to Heuermann, his former wife and daughter were found on belts, tape and burlap found on his alleged victims. 

So how did they connect those hairs they found on the bodies to Heuermann?

Shortly after he was arrested, prosecutors revealed they used DNA recovered from a discarded pizza crust investigators recovered from a Manhattan garbage can to make the connection to the hair found on the victims. 

Investigators had been looking into Heuermann after a witness recalled seeing a vehicle that matched the description of one he owned when victim Shannan Gilbert was last seen alive. 

In court documents, prosecutors released an image of what they called a “blueprint” Heuermann allegedly used “to plan out his kills with excruciating detail.”

The document has four columns. They are labeled “Problems,” “Supplies,” “DS” and “TRG.” 

Among the problems listed: DNA, tire marks, blood stains, finger prints and more. The supplies include rope/cord, saw/cutting tools, police scanner, hair nets, medical gloves and more. 

Additional things listed in the planning document, according to prosecutors, are three sections devoted to “pre-prep,” “prep,” and “post event.” Among the pre-prep things listed are vehicle inspection, weather report, and “recon vid. cams.” The “prep” list includes “set-up stage.” The “post-event” list includes “change tires,” “burn gloves” and “have story set.”

The document goes on to list “things to remember,” such as “sound travels.” 

Rex Heuermann, 62, grew up on Long Island. He attended Berner High School and lived in Massapequa Park.

Neighbors there were stunned when police swooped in to make their arrest at the house where, neighbors said, Heuermann grew up with his parents and brother. 

Heuermann was married at the time of his arrest and has a daughter. 

A neighbor described Heuermann as “very quiet, dark, kept to himself and extremely intelligent, very smart.”  

Heuermann worked in Midtown Manhattan as an architect and ran a company called RH Consultants and Associates. His office was located at 36th Street and Fifth Avenue. 

Police said a pizza box he left in the garbage near there was a key piece of evidence in the case.   

At the time of his arrest, he owed more than $425,000 in taxes, Nassau County records revealed. He also had filed several lawsuits accusing drivers of hurting him in car accidents. Three of those cases were either settled or discontinued. 

Since his arrest, he has been in near solitary confinement for 23 hours per day, in protective custody. 

The Gilgo Beach case began on May 1, 2010 as a search for Shannan Gilbert, a 23-year-old woman who was working as an escort. She made a frantic call to 911, saying she believed someone was after her. She vanished. 

An exhaustive search followed, but her body was not immediately recovered. 

In December, 2010, police found the bodies of four women near Gilgo Beach. They became know as the Gilgo Four. Three of them were wrapped in burlap. They were identified as Maureen Brainard-Barnes, Amber Costello, Megan Waterman and Melissa Barthelemy. All four worked as online escorts, police said. 

Brainard-Barnes went missing in 2007. Barthelemy went missing in 2009. Waterman disappeared in June of 2010, and Costello disappeared in September of 2010. 

In May, 2011, six more sets of remains were found.
