Long Island Serial Killer | The Trial Of Rex Heuermann

Someone tried to delete this file. Forensic analysts recovered it anyway. According to prosecutors, document HK2002-04 is the Long Island Serial Killer's literal how-to guide for murder.The file was hidden on one of fifty-eight hard drives seized from Rex Heuermann's Massapequa Park basement. Created in 2000, modified through 2002, it allegedly contained eighty-seven details prosecutors say match the methodology used on the Gilgo Beach victims.According to court documents: A "Supplies" section allegedly listed cutting tools, acid, tarps, and cat litter. A "Body Prep" section allegedly stated: "remove head and hands, remove ID marks like tattoos." A "Things to Remember" section allegedly contained lessons learned: "Hit harder... light rope broke under stress." References to specific pages in FBI profiler John Douglas's Mindhunter appeared throughout.Jessica Taylor's remains were found along Ocean Parkway with her head removed and tattoos mutilated—allegedly matching the document exactly. When investigators returned to Rex Heuermann's home with infrared equipment, they found adhesive residue and push pin evidence in the drop ceiling—exactly as allegedly described.DA Ray Tierney: "The exact method by which these murders were committed in excruciating detail in that document is in some cases identical to the methodology used to murder the victims."The family that lived with Rex for twenty-seven years has fractured completely. Wife Asa Ellerup still calls him her "hero" and describes jail visits like "a first date." Daughter Victoria reached a different conclusion after speaking with BTK's daughter: "most likely" guilty.According to prosecutors, female hairs on multiple victims were allegedly consistent with DNA from both women. Neither is accused—prosecutors say the hair transferred from clothing or the home. Women linked to murder victims they never knew existed.The daughter saw what the wife cannot. Both are victims. Just not of the same truth.Rex Heuermann has pleaded not guilty. Trial is September 2026.Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/Want to comment and watch this podcast as a video?

Part 5 of 5: How the alleged Long Island Serial Killer was finally arrested.Investigators had been watching the man they believed was LISK for months. They had cell tower evidence placing his phone with burner phones in every instance. But they needed DNA to make the Gilgo Beach case.Then he threw away a pizza box.In this final episode, we examine how a discarded pizza crust allegedly provided the evidence that led to charges in the thirteen-year Gilgo Beach cold case—and what happens when Rex Heuermann faces trial in September 2026.The investigation stalled for years after bodies were discovered along Ocean Parkway in 2010 and 2011. Then a new Suffolk County task force formed in February 2022. Six weeks in, an investigator noticed an old witness statement about an "ogre-like man" driving a Chevrolet Avalanche near where Amber Costello vanished.A database search returned one name.Cell phone records allegedly connected the alleged Gilgo Beach Killer to burner phones in every instance. But they needed physical proof.Enter whole genome sequencing—technology that can extract DNA from degraded samples. According to prosecutors, hairs on six of seven victims linked to LISK or his family.Then the pizza. DNA from the crust matched a male hair on Gilgo Four victim Megan Waterman. A profile found in only 0.04% of the population.July 13, 2023. The alleged Long Island Serial Killer arrested outside his Manhattan office. Twelve-day search of his Massapequa Park home. Fifty-eight hard drives. Over two hundred firearms. The planning document.The defense has challenged the DNA technology. Judge Mazzei allowed it—first time in a New York criminal trial. The LISK trial happens September 2026.After thirty years and seven women, the architect will finally face trial for the Gilgo Beach murders.Thank you for following this series.Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/Want to comment and watch this podcast as a video?

Part 4 of 5: How prosecutors say the alleged Gilgo Beach Killer selected, contacted, and killed his victims along Long Island.July 2009. Amanda Barthelemy, fifteen years old, received a call from her missing sister's phone. A man's voice asked: "Do you know what I did to your sister?"Over the following weeks, the man called seven times. He described what he'd done. On August 26, he said: "You won't see her again. I killed her."In this episode, we examine the alleged LISK hunting pattern that prosecutors say links Rex Heuermann to seven Long Island murders over three decades.The Gilgo Four and other victims share characteristics. All were sex workers. All were petite—the planning document allegedly notes "small is good." All advertised on Craigslist. All were allegedly contacted via burner phones. All allegedly disappeared when the alleged Long Island Serial Killer's family was traveling.According to court documents, investigators found no instance where Heuermann's personal phone was in a different location than burner phones used to contact the Gilgo Beach victims. The FBI traced calls to "the box"—a small area of Massapequa Park.Heuermann's house was inside the box.Suffolk County prosecutors also allege fake email accounts under names like John Springfield and Thomas Hawk—used to create profiles and contact sex workers. Even in 2022, investigators watched the alleged Gilgo Beach Killer add money to burner phones.And the alleged taunting went beyond phone calls. Prosecutors say LISK searched obsessively for the Ocean Parkway investigation. For photos of victims. For photos of their families.DA Tierney: "His intent was specifically to locate these victims, to hunt them down, to bring them under his control, and to kill them."Rex Heuermann has pleaded not guilty.

Part 3 of 5: The family fracture that defines the Long Island Serial Killer case.Asa Ellerup was married to Rex Heuermann for nearly three decades. In the Peacock documentary, she called him her "hero" and said Suffolk County police have "the wrong man." Their daughter Victoria has reached the opposite conclusion—telling producers she believes her father is "most likely the Gilgo Beach serial killer."Same house. Same twenty-seven years. Two completely different realities about LISK.In this episode, we examine what the alleged Gilgo Beach Killer's family saw and missed, why mother and daughter diverged, and what prosecutors say may have connected them to the alleged crimes without their knowledge.According to court documents, every murder Heuermann is charged with allegedly occurred when his family was out of town. Wife in Iceland, Maryland, New Jersey—each absence allegedly corresponded with a victim's disappearance along Ocean Parkway.But the connection runs deeper. Female hairs found on multiple victims' remains were allegedly consistent with DNA from Asa and Victoria. Neither is accused of involvement. Prosecutors say the hair was transferred from Rex's clothing.The women in the alleged Long Island Serial Killer's life were allegedly linked to murder victims without knowing.Victoria spoke with Kerri Rawson, BTK's daughter, about what it means to have an alleged killer for a father. By the documentary's release, she'd reached her conclusion about the Gilgo Beach murders.Asa still plans to attend every day of the LISK trial. Still calls Rex her husband.The trial is September 2026. Both will be in that courtroom—one believing innocent, one believing guilty.Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/Want to comment and watch this podcast as a video?

Part 2 of 5: The document prosecutors say proves everything about the Gilgo Beach murders.Hidden on one of fifty-eight hard drives seized from Rex Heuermann's Massapequa Park basement, forensic analysts found a deleted Microsoft Word file titled HK2002-04. According to court documents, it allegedly contained eighty-seven details prosecutors call LISK's "blueprint for serial murder."In this episode, we examine every section of the alleged Long Island Serial Killer's planning document and its connection to the Gilgo Beach victims.According to bail applications and court filings, the document allegedly contained: "Supplies": cutting tools, acid, hair nets, tarps, cat litter "TGR" (targets): notes that "small is good" for victims "DS" (dump sites): including Mill Road in Manorville, where Jessica Taylor and Valerie Mack were found "Body Prep": "remove head and hands, remove ID marks like tattoos" "Things to Remember": "hit harder," "heavy rope for neck—light rope broke" Jessica Taylor was found along Ocean Parkway decapitated with mutilated tattoos. The methodology allegedly matches.The Gilgo Beach Killer's document also allegedly referenced pages in FBI profiler John Douglas's Mindhunter—passages about perpetrator psychology and crime scene behavior. Prosecutors allege LISK studied how serial killers get caught.When Suffolk County investigators returned to the home, infrared examination allegedly revealed physical evidence matching the document: adhesive residue on paneling, push pins in drop ceilings.DA Tierney: "The exact method by which these murders were committed in excruciating detail in that document is in some cases identical to the methodology used to murder the victims."Rex Heuermann has pleaded not guilty.

Part 1 of 5: How did Rex Heuermann—the man prosecutors call LISK—allegedly hide in plain sight for thirty years?This is the beginning of our comprehensive series examining the case against Rex Heuermann, the Manhattan architect charged with the Gilgo Beach murders. Seven victims between 1993 and 2010. Remains discovered along Ocean Parkway starting in December 2010. He's pleaded not guilty to all charges. His trial is set for September 2026.In this episode, we examine the psychology of compartmentalization—the phenomenon that allegedly allowed the Long Island Serial Killer to live as a family man while prosecutors say he was hunting victims whenever his wife and children were out of town.His ex-wife Asa Ellerup still calls him her "hero." In the Peacock documentary, she said: "I know what bad men are capable of doing. Not my husband. You have the wrong man."Their daughter Victoria has reached a different conclusion. According to documentary producers, she now believes her father is "most likely the Gilgo Beach serial killer."Forensic psychologist Scott Bonn explains that killers like BTK and the Green River Killer had "the ability to flip a switch and go from family man to sadistic killer." Former FBI agent Robin Dreeke suggests predators often select partners for traits that make them less likely to investigate red flags.According to Suffolk County prosecutors, every murder the alleged Gilgo Beach Killer is charged with occurred during windows when his family was traveling. Wife in Iceland, Maryland, New Jersey, Virginia—each absence allegedly corresponded with a victim's disappearance.Same house. Same twenty-seven years. Two completely different conclusions about who LISK really is.The mask, if prosecutors are right, didn't slip for three decades.Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/Want to comment and watch this podcast as a video?

The biggest development in the Gilgo Beach case since Rex Heuermann's arrest. On January 13, 2026, Judge Timothy Mazzei finally set a trial date — right after Labor Day, September 2026. But the defense dropped a massive 178-page omnibus motion the night before that could change everything.Defense attorneys Michael Brown and Danielle Coysh are asking the court to dismiss the Sandra Costilla murder charge entirely. Costilla was killed in 1993 — the oldest case on the indictment. The prosecution's evidence linking Heuermann to her death: a single hair on her outer shirt. Not on her body. Not in a vehicle. Not in his home. The defense argues there's no eyewitness testimony, no surveillance, no digital evidence, no phone records, no fingerprints, no confession, and no murder weapon.They're also demanding all discovery related to convicted killer John Bittrolff, who's serving time for two Long Island murders with the same victim profile and geography. A former prosecutor previously stated Bittrolff was "probably responsible" for Costilla's death.The motion challenges twenty search warrants and argues the pizza crust DNA collection violated Heuermann's Fourth Amendment rights — a novel argument that could set precedent for how DNA evidence is collected in New York.Meanwhile, Andrew Dykes was just arrested in December for the murder of "Peaches" — long assumed to be a Gilgo victim. Different killer. Same beach.DA Ray Tierney says he's confident. Prosecution responds March 3rd. Defense replies March 17th. Trial begins September 2026. Seven murder charges. Life without parole on the line.#RexHeuermann #GilgoBeach #GilgoBeachMurders #LongIslandSerialKiller #SandraCostilla #JohnBittrolff #AndrewDykes #Peaches #GilgoBeachTrial #LISKJoin Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/Want to comment and watch this podcast as a video?

He looked like the guy next door — the dependable architect in a button-down shirt, the dad carrying groceries, the man waving from the driveway. But prosecutors say Rex Heuermann was also living a second life beneath that suburban shell: the man behind the Gilgo Beach murders, one of the most disturbing serial-killer cases in modern history. In this psychological deep dive, Hidden Killers host Tony Brueski exposes the mental architecture of control, deception, and compartmentalization that behavioral experts say may allow someone to construct two worlds that never touch. From high-functioning psychopathy to strict operational secrecy, Tony explores how a person can design blueprints by day and allegedly engineer terror by night — all while maintaining a façade so ordinary that no one close to him ever sees the cracks forming. Heuermann’s environment reflected his pathology: the soundproof basement, the meticulously organized tools, the rigid routines that enabled a double life to thrive. This episode breaks down how predators weaponize normalcy — and why the people closest to them often become the last to know. But there’s another layer: the family. As the case moves toward trial, questions loom about whether his ex-wife Asa Ellerup or his daughter could be called to testify. Tony is joined by defense attorney and former prosecutor Eric Faddis to unpack the emotional and legal stakes of family testimony, jury bias, and the impact of years of media coverage on a case already carved into the public consciousness. This episode blends behavioral profiling with legal strategy to show how monsters hide in plain sight — and how the justice system tries to reveal what the façade so carefully concealed. Because evil doesn’t always lurk in shadows. Sometimes, it stands at the front door smiling. #RexHeuermann #GilgoBeach #SerialKillerPsychology #HiddenKillers #TonyBrueski #BehavioralAnalysis #TrueCrimePodcast #AsaEllerup #FamilyTestimony #CriminalMind Want to comment and watch this podcast as a video?

In this powerful breakdown of the Gilgo Beach case, Tony Brueski and retired FBI Special Agent Jennifer Coffindaffer take listeners inside the evidence story prosecutors will present to a single jury—now that a judge has ruled all seven murder charges against Rex Heuermann will be tried together. This ruling reshapes the entire strategy on both sides of the courtroom, giving the state a sweeping narrative arc while handing the defense the ammunition to argue prejudice, jury overload, and unfair consolidation. We begin with the evidence tour: the infamous large doll, the cage, the secret room, the basement storage vault, and the forensic haul investigators collected during the search warrant execution. Coffindaffer walks through how prosecutors will try to connect these items to time, transfer, and intent—and why the defense will insist none of it is meaningful unless tied to scientifically grounded timelines and corroboration. The rule is simple: seized items aren’t guilt until they’re connected to the crime. Then we dive into the science. Whole genome hair sequencing may be “new to this courtroom,” but it’s not new to forensic research. The state will rely on validation studies and conservative conclusions; the defense will call it junk science. This battle could determine whether key DNA evidence even makes it to the jury box. We also explore the family factor: could Heuermann’s daughter testify? Would Asa Ellerup take the stand? And how would their emotional presence—or absence—shape juror perception? Finally, former prosecutor and defense attorney Eric Faddis breaks down the legal stakes of joinder: seven counts, one jury, decades of alleged conduct, and a trial timeline stretching realistically toward 2027. This isn’t just strategy—it’s a marathon requiring clean science, disciplined storytelling, and a jury willing to follow every step. This is the full picture: the evidence, the science, the strategy, and the stakes. #RexHeuermann #GilgoBeach #HiddenKillers #DNAEvidence #ForensicScience #JenniferCoffindaffer #EricFaddis #TrueCrimeNews #SerialKillerTrial #TonyBrueski Want to comment and watch this podcast as a video?

The Gilgo Beach case just took a seismic turn. A judge has ruled that all seven murder charges against Rex Heuermann will be combined into one massive, high-stakes trial — a decision that reshapes the legal battlefield and raises the pressure on everyone involved. In today’s episode, Tony Brueski and defense attorney/former prosecutor Eric Faddis break down what this ruling really means for the prosecution, the defense, and the jury tasked with navigating one of the most disturbing serial murder cases in American history. We examine why combining the charges could create a devastating narrative advantage for prosecutors, who will now be able to present a sweeping pattern of alleged behavior instead of siloed incidents. But this strategy also risks unfair prejudice, especially in a case already saturated with headlines, documentaries, and public speculation. Eric explains how jurors may psychologically struggle to separate evidence tied to each victim once everything is presented together. Then we turn to the wildcard that could influence the entire trial: Heuermann’s family. Could his ex-wife, Asa Ellerup, be compelled to testify? Would their daughter take the stand? And what about the documentary footage that captured intimate, raw emotional moments — could that become part of the evidentiary record? This episode explores the legal complexities of spousal testimony, impeachment risk, and whether family cooperation helps or hurts the defense. We also break down jury selection, the challenges of finding impartial jurors in New York, and the role advanced DNA techniques may play in establishing — or undermining — the state’s case. The ruling to consolidate the charges is not just procedural. It is transformational. If you’re following the Gilgo Beach case, this is the turning point you need to understand. #RexHeuermann #GilgoBeach #HiddenKillersLive #TrueCrimePodcast #SerialKillerCase #AsaEllerup #DNAEvidence #TrueCrimeNews #Justice #EricFaddis Want to comment and watch this podcast as a video?
