It’s been three months since the horrific murders at Sandy Hook Elementary School unfolded in Newtown, Conn. And as the police continue their investigation into what motivated 20-year-old Adam Lanza to commit the unthinkable, some disturbing, new (alleged) details have emerged.

Rather than a spur-of-the moment attack, a new report purports that authorities believe that Lanza spent a great deal of time researching and collecting information about past shootings. In fact, according to an article in the New York Daily News, his information-gathering was much more robust and progressed than previously thought.

An off-the-record source, described as an expert career cop, told the outlet about some of the shocking alleged revelations in the case. In addition to the notion that Lanza may have been planning his rampage for years, the source claims that authorities retrieved a massive spreadsheet — a document that is seven feet long and four feet in length (with nine-point font) — from the Lanza home.

In the document, the killer had allegedly assembled a plethora of information about past mass shootings. In addition to information surrounding horrific events that took the lives of countless Americans, the young man apparently also studied and documented attempted attacks.

This information, along with many other troubling details, was apparently recently shared by Colonel Danny Stebbins, a staff member with the Connecticut State Police, during an event for law enforcement officials.

According to the source, Stebbins shared the details with other police officers at the International Association of Police Chiefs and Colonels meeting last week. In his interview with the Daily News, the source called the document a “score sheet” and described its purpose in detail.

“We were told (Lanza) had around 500 people on this sheet,” he said. “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.”

Equally troubling was the bizarre world that Lanza apparently immersed himself in. An avid video game fan, cops purportedly believe that, at some point, the killer took his on-screen quest and translated it into a real-life, murderous bloodbath.

Here’s how the Daily News recapped the unnamed cop’s description of this portion of Stebbins’ speech:

“They don’t believe this was just a spreadsheet. They believe it was a score sheet,” he continued. “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.”

The man paused and said, “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.”

The first part of the source’s statement about schools’ vulnerability has been one advanced by gun control opponents and Second Amendment enthusiasts (i.e. the notion that gun-free zones breed or even attract danger). According to this account, Lanza specifically selected the school, because it was an easy target, complete with victims who were unable to adequately protect themselves.

Based on the Daily News’ interview with the source, Lanza certainly was “murder-obsessed,” as the outlet notes in the headline of its article.

“The fascination (Lanza) had with this subject matter, the complete and total concentration,” the cop said. “There really was no other subject matter inside his head. Just this: Kill, kill, kill.”
