About this listen

For nearly two decades, the remains of young women kept turning up along the desolate stretches of Long Island — in the scrub brush off Ocean Parkway, in wooded areas out east, in places no one was supposed to find them. And for most of that time, no one was held accountable. I'm Tony Brueski, and this podcast is my deep dive into one of the most chilling serial murder cases in modern American history — the Gilgo Beach murders and the case against Rex Heuermann, the New York architect now charged with the killing of seven women spanning from 1993 to 2010.

This isn't a case summary. It's the full picture — the women who were allegedly targeted and discarded, the investigative failures that let a suspected killer allegedly operate in plain sight for decades, and the forensic breakthroughs that finally led to an arrest in July 2023. I break down the evidence prosecutors have built — DNA analysis, cellphone data, digital files allegedly recovered from Heuermann's own computer — and the defense strategy aimed at dismantling it. I cover the courtroom battles, the rulings on evidence admissibility, and every development as this case moves toward its next chapter.

But more than anything, this podcast is about the women at the center of it all. Sandra Costilla. Valerie Mack. Jessica Taylor. Maureen Brainard-Barnes. Melissa Barthelemy. Megan Waterman. Amber Costello. They had names. They had people who loved them. And they deserve more than a headline.

New episodes drop regularly as the case develops. If you want to understand the Gilgo Beach murders — the facts, the failures, and what justice actually looks like when it finally shows up — you're in the right place.

  • Rex Heuermann: Eight Women, Seventeen Years, One Plea
    Apr 15 2026

    They packed the courtroom — the mothers, the sisters, the partners, the friends who spent years wondering and waiting and hoping that someone would be held accountable for the women they lost. Some had been waiting since the 2000s. Some since 2010, when the first four sets of remains were found wrapped in burlap along an isolated stretch of Ocean Parkway. And on April 8, in a hearing that lasted roughly thirty minutes, Rex Heuermann gave them the one thing he'd refused to give for nearly three years — the truth.

    Sandra Costilla. Valerie Mack. Jessica Taylor. Maureen Brainard-Barnes. Melissa Barthelemy. Megan Waterman. Amber Costello. Karen Vergata. Eight women. Eight lives ended by the same man over seventeen years. He described how he met them. How he strangled them. How he disposed of their remains across Long Island.

    Elizabeth Baczkiel, the mother of Jessica Taylor, said the plea took a weight off her family. Missy Cann, whose sister Maureen Brainard-Barnes was killed, said it brought solace after nineteen years of living between heartbreak and hope. The families were given a choice — accept the plea or push for trial. They chose the admission. They chose finality over the uncertainty of a courtroom proceeding.

    But finality comes with trade-offs. There will be no trial where every piece of evidence is laid out. No public cross-examination. No moment where a jury decides whether the prosecution's case held. The plea sealed the record on what happened in that proffer session. It protected Heuermann from further prosecution on any named victim. And it left the families of women who haven't been identified yet with the same unanswered questions they've carried for years. Heuermann's attorney says there are no other victims. The investigation hasn't stopped. And the question of whether eight is the real number belongs to the families who are still waiting.

  • Valerie Mack's Son Wants Answers the Plea Didn't Give
    Apr 15 2026

    Benjamin Torres never got to grow up with his mother. Valerie Mack disappeared when he was six years old. Her partial remains — dismembered, decapitated, hands severed — were found in Manorville that same year. Nobody knew who she was. For twenty years, she was listed as an unidentified woman. Torres spent his entire childhood, his adolescence, and most of his adult life without knowing what happened to her, without anyone being held accountable, and without a single person in the system telling him his mother's name had been attached to the remains found in those woods.

    Rex Heuermann has now pleaded guilty to killing her. That admission gives Torres something he never had — confirmation. But it doesn't give him everything. And that's why he filed a lawsuit that goes beyond the man who strangled his mother.

    The complaint names Asa Ellerup and Victoria Heuermann. It accuses them of knowing about the murders, of concealing what was happening inside the home, and of collecting over a million dollars from a documentary about the killings while showing what the lawsuit calls callous disregard for the families left behind. The defense calls it baseless. They say the family cooperated with law enforcement from the beginning. They say Victoria was approximately three years old when Mack was killed. They say prosecutors have never pointed the finger at either woman.

    Those are facts worth weighing. But so is the fact that a six-year-old boy lost his mother to a man who dismembered her body and hid the pieces across Long Island — and the people closest to that man collected a documentary payday while the victims' families were still burying what was left. Torres wants accountability beyond the guilty plea. Whether the court gives him that is a question the legal system will answer. But the question of who profited and who suffered is one the public is already asking.

  • Sandra Costilla Waited 30 Years — Heuermann Finally Pled Guilty
    Apr 13 2026

    Sandra Costilla was 28 years old when her body was found in the woods of Southampton, Long Island, in 1993. For three decades, nobody connected her death to the Gilgo Beach case. Investigators looked at the wrong suspect for years. Meanwhile, according to prosecutors, the man whose DNA was allegedly on her body was living undisturbed — building a career, raising a family, and allegedly killing other women for nearly two more decades after Sandra was gone.

    Rex Heuermann pled guilty to her murder. He pled guilty to murdering six other women. He admitted to killing an eighth victim — Karen Vergata. Life without parole. No trial. After nearly three years of fighting every piece of evidence, challenging the DNA, filing motion after motion, and losing each one — he stood in Suffolk County Court and admitted to all of it.

    Sandra's case changed everything about the timeline. Before prosecutors linked her to Heuermann, the Gilgo Beach killings were understood to have begun in 2007. Sandra pushes it back by 14 years. The DNA evidence that connected Heuermann to her was matched through technology that didn't exist during her lifetime. The defense tried to get it thrown out. The judge ruled it admissible. That ruling may have been the moment the defense knew there was nowhere left to go.

    Retired FBI Special Agent Jennifer Coffindaffer examines what the plea means for the families — what it provides, what it takes away, and what remains unresolved along the Gilgo Beach corridor where additional remains were found beyond the victims Heuermann was charged with killing. Heuermann has agreed to cooperate with the FBI going forward. But cooperation doesn't answer every question. It doesn't replace the trial these families were preparing to sit through. And it doesn't give Sandra Costilla back the three decades she spent as an unconnected case file while the man who allegedly killed her lived freely on the same island where her body was found.

    This is Episode 1 of "The Seven." One victim per episode. Their story first. The evidence second. Sandra waited the longest. Her name goes first.
