Investigator reveals Sandy Hook killer ADAM LANZA’s chilling spreadsheet – 7 feet long and 4 feet wide – that detailed Lanza’s research about mass murder and how to accomplish the nauseatingly gruesome feat.

“We were told (Lanza) had around 500 people on this sheet,” a law enforcement vet told The New York Daily News.

“Names and the number of people killed and the weapons that were used, even the precise make and model of the weapons. It had to have taken years. It sounded like a doctoral thesis, that was the quality of the research.”

“They don’t believe this was just a spreadsheet. They believe it was a score sheet,” the law enforcement vet elaborated.

 “This was the work of a video gamer, and that it was his intent to put his own name at the very top of that list. They believe that he picked an elementary school because he felt it was a point of least resistance, where he could rack up the greatest number of kills. That’s what (the Connecticut police) believe.”

 “They believe that (Lanza) believed that it was the way to pick up the easiest points. It’s why he didn’t want to be killed by law enforcement. In the code of a gamer, even a deranged gamer like this little bastard, if somebody else kills you, they get your points. They believe that’s why he killed himself.

“They have pictures from two years before, with the guy all strapped with weapons, posing with a pistol to his head. That’s the thing you have to understand: He had this laid out for years before.”
