Summary
Prosecutors call it LISK's "blueprint for murder." Defense calls it circumstantial. Today we examine every section of the planning document allegedly found on the Gilgo Beach Killer's hard drive.
The file was hidden in unallocated space—someone tried to delete it. Forensic analysts recovered it. According to court documents, it allegedly contained eighty-seven details organized into operational sections.
"Supplies" allegedly listed cutting tools, acid, tarps, cat litter. "Body Prep" allegedly stated: "remove head and hands, remove ID marks like tattoos." "Things to Remember" allegedly contained the Long Island Serial Killer's lessons from previous crimes.
"Hit harder," one entry allegedly read. "Light rope broke under stress of being tightened."
Suffolk County DA Ray Tierney stated: "The methodology in that document is in some cases identical to the methodology used to murder the victims in this case."
Jessica Taylor was found along Ocean Parkway decapitated with mutilated tattoos. Valerie Mack's remains were scattered in a similar pattern. The document allegedly describes exactly this methodology.
But here's the detail that takes the Gilgo Beach case to another level: references to FBI profiler John Douglas's Mindhunter. Specific page numbers. Prosecutors allege LISK studied behavioral analysis to avoid getting caught.
When investigators returned to the alleged Long Island Serial Killer's basement, infrared examination allegedly revealed physical evidence matching the document's descriptions. Adhesive residue. Push pins in the drop ceiling.
The defense has challenged the DNA evidence and pointed to other suspects. Rex Heuermann has pleaded not guilty to all Gilgo Beach murder charges.
The LISK trial is set for September 2026. Part 2 of 5.

| 0:26.1 | A file hidden in what's called unalloticated space. |
| 0:30.0 | What is unalloticated space? |
| 0:31.5 | Basically, when you're on your computer and you delete something and you take it to the |
| 0:36.3 | recycling bin or the trash bin and then you |
| 0:38.1 | empty it all right it's gone right it's it's no longer visible to you through that interface |
