"A document was found on a hard drive in the basement of Heuermann's home that prosecutors said was a "manifesto" or "blueprint" planning all phases of the killings and disposal of the bodies.
Prosecutors said the Microsoft Word document was a "planning document" used by Heuermann to "methodically blueprint" and "plan out" his "kills".
The planning document was divided into sections, including "problems," such as DNA, tire marks, blood stains, fingerprints, plastic bags/cat litter, witnesses, trace source of supplies, foot/shoe prints, photos, police and truck stops, fingerprints in gloves, hair and fiber, prosecutors said.
There was also a section for supplies needed to carry out serial murders "to avoid apprehension and to avoid leaving behind DNA evidence," the DA said."
"His intent was to hunt them down. Bring them under his control — and kill them." Rex Heuermann now stands charged in 6 of the Gilgo deaths.
