Report: Investigators found Lanza's spreadsheet documenting mass murders

Months after the terrible attack at Sandy Hook Elementary School more information is still coming out about what led up to the murders and how long Adam Lanza had been planning the attack.

It's been one of the hardest questions to answer, why did he do it? Why did a young man from Connecticut murder his mother and then open fire on dozens of children at an elementary school, killing 26 people two weeks before Christmas.

Now the signs point to notoriety as the motivation for that Adam Lanza.

Investigators reportedly found a spreadsheet, seven feet long and four feet wide, filled with information about mass murders and even attempted murders from the past.

A law enforcement officer who attended an international meeting of Police Chiefs last week told a reporter for the New York Daily News there were about 500 people included on the spread sheet. Not just names, but types of weapons used, the number of people killed. It was the type of research that may have taken years to complete.

The spreadsheet was found at Lanza's home after the massacre at Sandy Hook, an attack former FBI agent Brad Garrett has said seemed to be well planned in advance.

Garrett said Lanza picked a place where he knew he could inflict a lot of damage. "Mass shooters tend to look for soft targets because they're easy. They want to be able to walk into a situation where people are not armed, they have no idea what's going to happen to them and you can get the jump on them."

The law enforcement officer, who did not want his name used, said the spreadsheet that Lanza had created looked like a score sheet. The type of thing created by a video gamer to keep track of players' scores, so he could put his name right at the top.

He said cops think Lanza killed himself because he didn't want to lose his lead in the game. In a video gamer's mind, if someone else kills you, they get all your points. That may be what Lanza believed would have happened had he been taken down by the cops.
