{"type":"rich","version":"1.0","title":"Sandra Costilla Waited 30 Years — Heuermann Finally Pled Guilty","description":"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.\n\nRex 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.\n\nSandra'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.\n\nRetired 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.\n\nThis is Episode 1 of \"The Seven.\" One victim per episode. Their story first. The evidence second. Sandra waited the longest. Her name goes first.\n\nJoin Our SubStack For AD-FREE ADVANCE EPISODES & EXTRAS!: https://hiddenkillers.substack.com/\n\nWant to comment and watch this podcast as a video?
