GILGO BEACH MONSTER'S MURDER MANUAL FOUND!

Cunning serial killer suspect planned everything down to the last awful detail

ACCUSED Gilgo Beach serial killer Rex Heuermann drew up a stomach-churning blueprint for murder, including a deranged desire to have “more play time” with his victims, say New York authorities.

The stunning revelations are based on documents investigators say they found on the 60-year-old architect’s computer that chillingly detail his methodology for murder, noting how he scoped out potential victims, scouted sites to dump bodies and even listed “lessons learned” during the killings.

“Hit harder,” says one note in a Things to Remember section. “Consider a hit to the face or neck next time for take down.”

The grisly murder manual reads like a how-to guide for homicidal maniacs.

In a section labeled “supplies,” a list includes medical gloves, photo film, body washes, saw/cutting tools and lye/acid, the latter presumably needed to dissolve human remains. Another section, labeled “problems,” includes “foot/shoe prints,” “DNA,” “blood stains,” “hair & fiber” and “tire marks.”
