Heuermann Admitted to Eight Killings — The Full Story

He ate pizza on a Manhattan sidewalk and threw the crust in a public trash can. Investigators were watching. That discarded crust — legally recovered as an abandonment sample — carried DNA that matched a male hair found in the burlap wrapping around Megan Waterman's body on Ocean Parkway. Months of surveillance, one piece of garbage, and the entire Gilgo Beach case broke open.

Megan was 22. A mother from Scarborough, Maine, who called her three-year-old daughter every single day. When those daily calls stopped in June 2010, her family reported her missing within two days. Surveillance footage from the Holiday Inn Express in Hauppauge captured her walking out the door at 1:15 a.m. to meet a client. She was found six months later alongside Melissa Barthelemy, Maureen Brainard-Barnes, and Amber Lynn Costello — the Gilgo Four.

Rex Heuermann stood in a Suffolk County courtroom and pleaded guilty to murdering all seven women he was charged with killing — Barthelemy, Brainard-Barnes, Costello, Sandra Costilla, Valerie Mack, Jessica Taylor, and Waterman. He also admitted to intentionally causing the death of Karen Vergata, an eighth victim. He confirmed all eight were killed by strangulation. Prosecutors allege his electronic devices held checklists, methodology notes, and instructions for destroying evidence — a digital blueprint stored in a home he shared with his family. Every killing allegedly took place when his wife and children were away.

His attorney described the plea as "relief." The deal requires Heuermann to cooperate with the FBI's Behavioral Analysis Unit. This week's coverage walks through Megan's life before she became a case file, the DNA chain that made the prosecution's case, the mechanics of the plea deal, and expert analysis from Robin Dreeke and Eric Faddis on what the behavioral evidence tells us about who Heuermann actually is.
