Long Island Serial Killer | The Trial Of Rex Heuermann Rex Heuermann Part 2: THE BLUEPRINT — Inside the Alleged LISK Planning Document
Part 2 of 5: The document prosecutors say proves everything about the Gilgo Beach murders.
Hidden on one of fifty-eight hard drives seized from Rex Heuermann's Massapequa Park basement, forensic analysts found a deleted Microsoft Word file titled HK2002-04. According to court documents, it allegedly contained eighty-seven details prosecutors call LISK's "blueprint for serial murder."
In this episode, we examine every section of the alleged Long Island Serial Killer's planning document and its connection to the Gilgo Beach victims.
According to bail applications and court filings, the document allegedly contained:
-
"Supplies": cutting tools, acid, hair nets, tarps, cat litter - "TGR" (targets): notes that "small is good" for victims
- "DS" (dump sites): including Mill Road in Manorville, where Jessica Taylor and Valerie Mack were found
- "Body Prep": "remove head and hands, remove ID marks like tattoos"
"Things to Remember": "hit harder," "heavy rope for neck—light rope broke"
Jessica Taylor was found along Ocean Parkway decapitated with mutilated tattoos. The methodology allegedly matches.
The Gilgo Beach Killer's document also allegedly referenced pages in FBI profiler John Douglas's Mindhunter—passages about perpetrator psychology and crime scene behavior. Prosecutors allege LISK studied how serial killers get caught.
When Suffolk County investigators returned to the home, infrared examination allegedly revealed physical evidence matching the document: adhesive residue on paneling, push pins in drop ceilings.
DA Tierney: "The exact method by which these murders were committed in excruciating detail in that document is in some cases identical to the methodology used to murder the victims."
Rex Heuermann has pleaded not guilty. The Gilgo Beach trial is September 2026.
