The Gilgo Beach Murders: The Case Against Rex Heuermann

Sandra Costilla was twenty-eight years old when her remains were found in the woods of Southampton, Long Island, in 1993. For thirty years, her case sat cold. Investigators pursued the wrong suspect. Nobody connected her death to the Gilgo Beach killings. And then DNA technology that didn't exist during her lifetime linked her to Rex Heuermann — and pushed the entire timeline of his alleged crimes back by fourteen years.This look back puts Sandra first — her life before the case file, the decades her family spent without answers, and the forensic breakthrough that finally brought her name back into the investigation. Before Sandra's connection was established, the Gilgo Beach killings were understood to have begun around 2007. Her case changed the scope of everything investigators believed about how long Heuermann had been operating.Heuermann eventually pleaded guilty to Sandra's murder along with six others, and admitted to an eighth killing as part of the agreement. He confirmed strangulation as the cause of death for each victim. The defense had tried to exclude the DNA evidence that connected him to Sandra — matched through advanced whole genome sequencing — and the judge ruled it admissible. He is expected to be sentenced to three consecutive life terms plus an additional hundred years. We revisit where the case stood at the time of our reporting. Sandra waited thirty years for someone to say her name in a courtroom connected to the person who took her life. This segment says it first.Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/ Want to comment and watch this podcast as a video?

Melissa Barthelemy’s sister answered a phone call from the man who had just killed Melissa. He described what he did. That detail emerged during the sentencing of Rex Heuermann — three consecutive life terms, a hundred years, families chanting ogre as officers removed him from the courtroom.The sentence is supposed to be the end. But inside the plea deal is a question the families can’t let go of. Heuermann confessed to killing Karen Vergata during a proffer session — a woman he was never charged with. He brought her up himself. He volunteered it for credit. The judge said “eight that we know of.”The plea covers New York. Heuermann owned property in South Carolina and Nevada. Both are death penalty states. Women disappeared near those properties. If Heuermann’s cooperation was designed to close the case in the one state that can’t execute him while keeping the other jurisdictions quiet, the families who chanted ogre in that courtroom may not have gotten the full accounting they deserve.A look back at the most compelling stories of the week.Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/Want to comment and watch this podcast as a video?

Rex Heuermann is serving life without parole for the Gilgo Beach murders. He confessed to eight killings. Seven happened in the Massapequa Park basement. He admitted it privately to Asa and Victoria before his courtroom plea. He told Victoria the victims were not real people to him.And Asa Ellerup is still talking to him. Still visiting. Still managing the relationship on his terms. The Peacock documentary captured phone calls where Rex directed the family from his cell, insulted Asa and Victoria’s ability to communicate, and still ran the room. And Asa’s response on camera — what she said about those calls and what she will not say to Rex — tells you who this version of Rex actually serves.She was adopted and never bonded with her family. She was assaulted as a teenager. Her first marriage collapsed. Then Rex showed up and built the only stable world she’d ever known. That world is still standing. She just remodeled it.Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/ Want to comment and watch this podcast as a video?

Amanda Funderburg stood in a Suffolk County courtroom and addressed the man who killed her sister, Melissa Barthelemy. She told the court about a phone call. A call Heuermann made to her after the murder. What he said on that call is not something you forget.Heuermann was sentenced to consecutive life terms. Judge Mazzei was visibly emotional. He asked Heuermann if he was sorry. Called him a disgusting, despicable small man and a coward. Ordered him removed from the courtroom as the families chanted ogre.That sentencing closed one chapter. The cooperation agreement opens another. Heuermann will sit with the FBI’s Behavioral Analysis Unit and describe everything — how he chose his victims, how he killed them, how he maintained a Manhattan career and a suburban family for seventeen years while the bodies accumulated near Gilgo Beach. His defense attorney says he is required to be truthful, accurate, and complete. Former FBI agents say the chances he stopped at eight are limited to none. Jennifer Coffindaffer, contributor to Hidden Killers, explains why Funderburg’s testimony matters to the BAU and what the cooperation sessions may reveal beyond the eight confirmed victims.Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/Want to comment and watch this podcast as a video?

According to reporting, Rex Heuermann sat in his cell at the Riverhead Correctional Facility six weeks after his arrest and wrote a letter. Not to a friend. Not to family. To Keith Hunter Jesperson — the Happy Face Killer — a man convicted of killing at least eight women during the 1990s.And one of the things the Gilgo Beach killer reportedly wanted to know? Whether Jesperson had butter for his bread in prison.The LISK — the man who admitted to strangling eight women and scattering their remains across Long Island — settling into jail life by asking another serial killer about food. According to those who’ve seen the letter, Heuermann’s tone was calm. Settled. He wrote that he’d been doing “a lot” of thinking. He reportedly called Jesperson’s letters “a help and a comfort.”Jesperson had reportedly urged Heuermann to confess and take a plea. Heuermann ignored the advice for nearly three years — and then did exactly that when he pleaded guilty in April 2026 to seven murders and admitted killing an eighth.I break down the full content of that letter, the psychology of why Jesperson reached out, why he then forwarded Heuermann’s response to a podcaster, and what forensic research tells us about why killers seek each other out. I also cover Heuermann’s jail reading list — crime novel after crime novel about serial killers — and what Sheriff Toulon said after watching him for over a thousand days without seeing a single change in the man’s expression.The families’ attorney called them both what they are: losers and cowards who chose the most vulnerable people they could find.Links:Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/ Want to comment and watch this podcast as a video?

She did a documentary. She reportedly collected over a million dollars for it. And while she was talking to cameras about nightmares in the basement, the families of Rex Heuermann’s victims were preparing a lawsuit that calls her a co-conspirator.Asa Ellerup is named in a wrongful death lawsuit filed by Valerie Mack’s son. So is her daughter Victoria. So is Rex Heuermann. The allegation is civil conspiracy — that Asa knew or deliberately avoided knowing what was happening inside the house she shared with a serial killer for twenty-seven years, and that she helped conceal it.This is not a criminal charge. The DA’s office already cleared her. But a civil case does not need proof beyond a reasonable doubt. It needs a preponderance of evidence — more likely than not. And in that framework, the evidence prosecutors dismissed takes on different weight.Her hair was on the victims. Prosecutors said transference. She said on camera she did what she had to do to protect herself and her children. She renovated the basement where investigators say seven murders occurred and sleeps there. The lawsuit calls the documentary money unjust enrichment — profiting from the murders that destroyed the plaintiffs’ families.Defense attorney and former prosecutor Eric Faddis breaks down whether civil conspiracy sticks when the criminal investigation already cleared her, what the documentary payout means legally, and whether the endgame is not a verdict but a deposition — Asa Ellerup, under oath, answering twenty-seven years of questions for the first time.The criminal case is finished. The civil case is asking the questions the criminal case never did.END LINKS:Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/ Want to comment and watch this podcast as a video?

Rex Heuermann told Asa Ellerup he killed eight women. Seven of them in the basement. She called him Mr. Heuermann during the conversation. Then she gutted that basement, rebuilt it from the studs, and moved into it. She sleeps there. She says the dreams follow her every night. She says they always will.She chose not to attend sentencing. Her daughter says she believes Rex most likely did it. A victim's son who was six years old when his mother was murdered has filed a lawsuit alleging the family knew or looked away. The community wants the house demolished. Asa will not go.This is the full three-part conversation between psychotherapist Shavaun Scott and Tony Brueski — covering the confession that ended twenty-seven years of marriage, the double life that sustained seventeen years of murder, and the impossible position Asa is in now. Every detail verified. Every question grounded in reporting from the Peacock documentary, the guilty plea, and the wrongful death lawsuit. If you have been following this case, this is the conversation that puts it all in one place.Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/ Want to comment and watch this podcast as a video?

He faced the DA and answered every question in one or two words. Strangulation. Yes. Eight. He did not turn around to look at the families of the women he killed. He did not look at his own daughter. He stood with his hands shackled behind his back in a dark suit and gave the courtroom nothing.Rex Heuermann maintained a double life for seventeen years — suburban architect and father on one side, serial murderer on the other. He planned each killing for when his wife and children were out of town. His attorney described the plea as a huge relief. A friend said he was always respectful to women.Psychotherapist Shavaun Scott joins Tony Brueski for a conversation about what the courtroom presentation reveals about someone who has compartmentalized violence for that long. Whether the refusal to look at the gallery is control, indifference, or something the clinical literature has a name for. And whether a mind that walled itself off for two decades can provide useful information to the FBI Behavioral Analysis Unit, which Heuermann is now required to cooperate with as part of his plea deal.Join Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/ Want to comment and watch this podcast as a video?
