Prosecutors in the LISK case recovered a Word document from Rex Heuermann's basement hard drive — allegedly created in 2000 — that outlined how to select victims, dispose of remains, and avoid capture. They matched the accused Gilgo Beach Killer's DNA to hairs found on and near multiple victims using whole genome sequencing, admitted for the first time in New York history. And the original break came from a pizza crust the accused Long Island Serial Killer discarded during surveillance.

Defense attorney and former felony prosecutor Eric Faddis joins me to walk through both pillars of the Gilgo Beach Killer evidence. We examine the planning document's alleged contents — sections on supplies, problems, disposal sites, targets, and references to "Mindhunter" — and why the LISK defense reportedly never challenged its authenticity. We trace the DNA chain from a piece of trash to matches across multiple crime scenes spanning years. And we break down the Frye hearing that admitted whole genome sequencing — what the defense argued, what the judge ruled, and why it matters.

Faddis explains what the forensic recovery of deleted files from over 350 seized devices actually involves, where the science has vulnerabilities, and which piece of evidence he believes is the reason Rex Heuermann is reportedly pleading guilty.

For anyone who wants to understand the evidence at the center of the Gilgo Beach Killer case — this is the deep dive.
