Rex: The Gilgo Beach Architect | The Rex Heuermann Investigation
Rex Heuermann murdered eight women on Long Island between 1993 and 2010 while working as a Manhattan architect for companies like American Airlines, Target, and Nike. The investigation that should have caught him was obstructed by the very officials running it, with three Suffolk County law enforcement officials eventually going to federal prison for corruption that kept the FBI locked out of the case for years.
This series reconstructs the entire Gilgo Beach case from court filings, cell tower records, DNA evidence, witness testimony, and the public record. Every claim is sourced and cited on NBN.fm.

4 51 AM, May 1, 2010. Shannon Gilbert dials 911. Someone is after me. They are trying to kill me. The call lasted 22 minutes. She screamed. She went silent. She screamed again. By the time police arrived, she was gone.
SPEAKER_0122 minutes. Uh I really want you to sit with that specific number for a second. Because if you call 911, you generally expect an emergency response in minutes. The idea of a 24-year-old woman spending 22 continuous minutes on an open line with a dispatcher, uh running blindly through the dark terrain of an isolated barrier island is just an absolute nightmare scenario.
SPEAKER_00You are listening to Rex, the Gilgo Beach architect. And just so you know, every document, court filing, and forensic report discussed is available on the Neural Broadcast Network website. We are dropping you directly into the night of May 1st, 2010 on Oak Beach.
SPEAKER_01Right, because this isolated strip of land is where the entire investigation begins. To understand what happened, we really have to start with the only piece of absolute undeniable audio evidence we have from that night.
SPEAKER_00And we are pulling from the public release of the audio recordings alongside the detailed investigative reports from NBC New York and the disappear blog. Looking at the document here, and it specifically says the call lasted 22 minutes, alternating between coherent speech and disorientation.
SPEAKER_01Yeah, that alternation is key to understanding her state of mind because we hear severe distress. At certain points, her words are distinctly slurred. At other points, she screams audibly right into the receiver.
SPEAKER_00But what really stands out to an investigator are the extended periods of absolute silence, right? So a dispatcher is on the line, actively trying to elicit a response, trying to figure out what is happening, and there's just dead air.
SPEAKER_01Exactly. And right at the beginning of the call, there is a massive point of confusion. She did not, or perhaps given her state, she physically could not provide her exact location to the dispatcher.
SPEAKER_00Aaron Powell Which is critical because she is on a barrier island. It is dark, she is running. That specific lack of a concrete address severely delayed the dispatch of a patrol unit.
SPEAKER_01Aaron Powell But we have to look at the official narrative the authorities built around this call. For a very long time, the public was told this was a tragic, isolated event, just an accident. But if you cross-reference that narrative against the legal maneuvers of the police department, a glaring institutional gap emerges.
SPEAKER_00Well, let me push back on that official narrative immediately. Suffolk County police fought a judge's order to keep this 911 tape confidential for 12 years.
SPEAKER_0112 years? It makes no logical sense.
SPEAKER_00Right. If this was simply a routine missing person case, or if she just tragically drowned in a marsh by accident, why would a police department engage in an intense, decade-long legal battle to suppress a victim's cry for help?
SPEAKER_01Police departments release 911 calls from accidental deaths all the time, mainly to clear up public confusion. Shielding this specific tape for over a decade heavily suggests the department knew the audio fundamentally contradicted their preferred theory of the case.
SPEAKER_00So she is on the phone for 22 minutes, entirely panicked. But she isn't just standing still in a well-lit room. To understand why the dispatcher couldn't just pinpoint her location and send a squad car immediately, you have to picture where she actually is.
SPEAKER_01Yeah, explain the geography because the physical environment is basically a central character in this timeline. Oak Beach isn't your typical suburban neighborhood with sidewalks and streetlights.
SPEAKER_00Not at all. Oak Beach is a private, gated community situated right on a barrier island. The geography is intensely isolated. You have the Atlantic Ocean bordering one side and dense, overgrown marshland bordering the other.
SPEAKER_01And at nearly five in the morning, visibility is near zero.
SPEAKER_00Exactly. There are no street lamps illuminating the brush. It is damp, it is cold, and the terrain is treacherous. Based on witness statements from the neighborhood, we can construct a physical timeline of her flight.
SPEAKER_01Around 5 a.m., Shannon fled the house she had been visiting. She ran to the home of an elderly neighbor named Gus Colletti.
SPEAKER_00I'm looking at the document here, and it specifically says Colletti let her inside. He observed that she was completely panicked and disoriented.
SPEAKER_01He recognized the severity of her state immediately, so Colletti initiated his own 911 call. He is actively trying to get her help.
SPEAKER_00But here is where the psychology of extreme panic really takes over. The record indicates she refused to wait for the police to arrive at Colletti's residence. She ran back out into the darkness of the neighborhood.
SPEAKER_01She is running for her life. She finds a safe harbor with a neighbor who actually calls the police for her, and her response is to run away from that safe harbor back into the pitch black street.
SPEAKER_00Yes. And from an investigative standpoint, you really have to analyze what would drive a person to do that. Was she hallucinating? Was the threat she perceived so overwhelming that staying in one place felt like a death sentence?
SPEAKER_01The subsequent physical evidence of her path comes from multiple neighbors. They reported hearing loud banging on their doors. This was followed by more screaming, and then total silence.
SPEAKER_00And by the time Suffolk County police patrol units actually arrived at Oak Beach, the area was entirely empty. The neighbors are awake, the doors have been banged on, but Shannon is gone.
SPEAKER_01This erratic flight forces us to analyze a significant mismatch in the behavior. We really have to compare Shannon's final hours to the broader investigative record of the series.
SPEAKER_00You mean the profile we are building of the Gilgo Beach architect? We know how Rex Eurman operated.
SPEAKER_01Right. The verified evidence from the other murders paints a very specific picture. The bindings, the burlap camouflage, the precise post-mortem disposal along the highway.
SPEAKER_00Everything demonstrates a methodical, highly controlled pattern. The killer wanted absolute silence.
SPEAKER_01Now contrast that with the chaos of May 1st, 2010. That chaos fundamentally contradicts Rex Hewerman's documented methodology.
SPEAKER_00Shannon Gilbert running wildly through a neighborhood, initiating a 22-minute 911 call, banging on random doors, alerting multiple witnesses, does not align with a careful, silent predator.
SPEAKER_01Are you saying she doesn't fit the profile at all?
SPEAKER_00I am saying this discrepancy strongly suggests Shannon Gilbert is not conclusively linked to Rex Hewerman. The circumstances of her disappearance are loud and messy. Rex Heurriman's killings were silent and calculated.
SPEAKER_01So to understand what precipitated this loud, messy flight through Oak Beach, we have to step back in the timeline to 2 a.m. on May 1st. Who is she with and why is she there?
SPEAKER_00According to the investigative records documented by CBS 48 Hours, Shannon was a 24-year-old escort operating out of New Jersey. She was driven to a residence on Fairway Drive by her driver, Michael Pack.
SPEAKER_01And the purpose of the visit was to meet a client named Joseph Brewer. The timeline established by witness accounts shows that the encounter deteriorated over the next couple of hours.
SPEAKER_00Gilbert began exhibiting highly erratic behavior inside the home. Brewer eventually contacted Pack, who was waiting outside, requesting that he enter the house and remove her from the premises.
SPEAKER_01We actually have audio findings from the 911 tapes released in late 2022 that confirm their presence during this crisis. Both Brewer and Pack can be heard in the background of the 22-minute call. They are actively trying to get her to leave the house.
SPEAKER_00They submitted to questioning, they fully cooperated with authorities, and they were officially cleared of any wrongdoing regarding her disappearance. Okay, hang on. I need to challenge the record here because there is a massive timeline discrepancy. Shannon fled the Fairway Drive residence around 5 a.m. She is knocking on Coletti's door shortly after.
SPEAKER_01We know that by the time Suffolk County police arrive on the scene, Shinan had vanished into the marsh. But according to the record, Brewer and Pack were also gone.
SPEAKER_00That is exactly what the official timeline reflects. If a woman is in extreme distress, exhibiting severe disorientation, screaming into a phone that someone is trying to kill her, and then runs blindly into a dark marshland, does the investigative record adequately explain why the two men responsible for bringing her to that isolated location just departed before law enforcement arrived to assess the situation?
SPEAKER_01It is a glaring question. You have a driver whose sole job is to protect and transport this woman. You have a client whose house she just fled in a state of terror. The police are en route, yet they leave the scene.
SPEAKER_00The official record accepts their departure, but from an analytical standpoint, it leaves a void in the narrative that defies basic common sense.
SPEAKER_01And that void brings us to the agonizing gap in the forensic timeline. The initial police response failed to locate her. They searched the immediate area, but they found absolutely nothing.
SPEAKER_00It took 18 months to find her remains. 18 months of zero answers. On December 13th, 2011, investigators finally located her body.
SPEAKER_01She was found in a dense, unforgiving marsh between Oak Beach and Ocean Parkway. The location was roughly half a mile from where she was last seen alive by Gus Coletti.
SPEAKER_00The official conclusion from the Suffolk County Medical Examiner ruled the cause of death as undetermined. But they heavily suggested the most likely scenario was accidental drowning.
SPEAKER_01They theorized that she succumbed to the elements, became trapped in the thick, muddy terrain of the marsh, and essentially drowned in the muck.
SPEAKER_00That is the official theory. But the physical evidence from a secondary examination directly contradicts that narrative.
SPEAKER_01In 2014, at the relentless insistence of Shannon's mother, Mary Gilbert, forensic pathologist Michael Baden conducted an independent autopsy on the remains.
SPEAKER_00Baden's examination yielded a critical forensic finding. I'm looking at the document here, and it specifically says he documented damage to Shannon's hyoid bone.
SPEAKER_01We really need to explain exactly what that means. The hyoid is a small U-shaped bone situated deep in the throat at the root of the tongue.
SPEAKER_00And in forensic pathology, a fracture or significant damage to the hyoid bone is frequently associated with manual strangulation.
SPEAKER_01Let's use an analogy here to make the mechanism of this injury clear. Think of the hyoid like a very delicate wishbone sitting right at the base of your tongue. It is tucked away. It is protected by muscle and tissue.
SPEAKER_00If you trip in the dark and fall face first into a muddy marsh, the mud spreads the impact across your face, your chest, your shoulders. Mud does not have fingers.
SPEAKER_01It cannot pinch and snap a wishbone hidden deep inside your neck. Breaking that bone requires targeted, crushing pressure.
SPEAKER_00Precisely. We have to weigh the official accidental drowning theory against this physical pathology. Can the existing medical record ever truly reconcile a broken hyoid bone with a victim accidentally drowning in a marsh?
SPEAKER_01Environmental exposure and marshland terrain simply do not exert the localized pressure required to damage the hyoid.
SPEAKER_00This contradictory evidence is the most significant unanswered variable in the case. It permanently splits the official law enforcement narrative from the independent forensic pathology.
SPEAKER_01You have the police saying the environment killed her, and you have the physical anatomy heavily suggesting a person killed her.
SPEAKER_00The only reason we even have that independent pathology report is because of one person. We need to synthesize these evidence threads by focusing on the catalyst of this entire investigation, Mauri Gilbert.
SPEAKER_01The investigative record is completely clear. Without Mari, there is no broader search. Sources describe her as the most provocative personality among the families of the victims.
SPEAKER_00She was the one who made noise when the official investigation grew quiet. She refused to let the police dismiss her daughter as a runaway or a tragic accident.
SPEAKER_01Her advocacy had a massive cultural impact. She drew national media attention through sheer force of will, making appearances on programs like 48 hours. Her fight was eventually depicted in the Netflix film Lost Girls.
SPEAKER_00She forced the police to expand their search grid along Ocean Parkway. She simply refused to accept that her daughter wandered into a marsh and vanished without a trace.
SPEAKER_01But the end of her advocacy is a separate tragedy altogether. It is documented in the police reports from Ellenville, New York.
SPEAKER_00On July 23, 2016, Maury Gilbert was murdered at the age of 52. She was killed by her own daughter, Sarah.
SPEAKER_01The details are brutal, but they are necessary to understand the full scope of the devastation this family endured. The specific facts from the CNN source outline the severity of the attack.
SPEAKER_00She was then bludgeoned with a fire extinguisher.
SPEAKER_01Sarah Gilbert had suffered severe mental health deterioration following Shannon's disappearance and death. During the investigation into Mari's murder, Sarah reported hearing voices calling her mother the devil.
SPEAKER_00She was entirely consumed by the psychological fallout of losing her sister. She was ultimately convicted and received a sentence of 25 years to life.
SPEAKER_01The generational devastation is absolute. Mari Gilbert fought the legal system and the law enforcement apparatus for years to find the truth about Shannon. She tore down every wall they put up.
SPEAKER_00But she never lived to see the arrest of Rex Huerman. We arrive at the core investigative reality of this entire timeline.
SPEAKER_01On December 11, 2010, a K-9 unit conducting a search operation, specifically looking for Shannon's remains, deviated slightly from their path along Ocean Parkway.
SPEAKER_00Instead of finding Shannon, they found the remains of Melissa Bartholomew. The search for Shannon Gilbert is what led to the discovery of all the other bodies hidden in the brush. The irony is absolute.
SPEAKER_01She may not be Hurriman's victim, but without her 911 call and her mother Mary Gilbert's relentless advocacy, the Gilgo 4 and six additional victims might never have been found.
SPEAKER_00Next time a Microsoft Word document recovered from a deleted hard drive, categories, problems, supplies, dump sites, targets, HK 200204, the planning blueprint of a serial killer.
