[Updated at 10:52 a.m. ET] Investigators have found evidence that Sandy Hook Elementary School gunman Adam Lanza "was obsessed" with other mass murderers, a source with knowledge of the investigation told CNN Tuesday.
This news follows an earlier report that Lanza may have been motivated by a desire to outdo Anders Behring Breivik, the Norwegian man who killed 77 people in July 2011, law enforcement sources told CBS Evening News.
[Posted at 1:43 a.m. ET] The shooting spree at Sandy Hook Elementary School may have been motivated by a desire by Adam Lanza to outdo Anders Behring Breivik, the Norwegian man who killed 77 people in July 2011, law enforcement sources told CBS Evening News.
The unnamed sources said Lanza saw himself as being in direct competition with Breivik, who killed eight with a bombing in downtown Oslo before he moved to a nearby island where he hunted down and fatally shot 69 people.
According to the sources, the 20-year-old Lanza wanted to top Breivik's death toll and went to the Connecticut school on December 14 because it was the "easiest target" and had the "largest cluster of people."

Christian terrorism anyone? No? I agree. This has nothing to do with Christianity. But then nor does Islamic terrorism have anything to do with Islam.
so I guess muslim terrorists, claiming attacks in the name of Islam has nothing to do with Islam... yeah no you're totally right nothing to do with Islam.
Son, you keep talking crazy stuff like that, I SWEAR I will have you committed!
Don't feel bad AT. Every time I bring up the subject of violent video games being part of the problem, I get lamblasted.
the reason you get iamblasted, is because your argument is complete bunk! (BS) i play violent video games nearly everyday, kill people friends and such, but i don't want to go out killing people, so am i special or are the studies wrong? (ironic cause of my username)
Good morning @bobcat
Well this 'poor' boy just wanted to emulate that Norwegian who had massacred 0nly 77 innocent young people.And had gotten away with 20 yrs (make that half with good behaviour)
I know its a light sentence for such a crime.. also the Norwegian police managed to capture him and bring him to trial. Without killing him or burning down the place.
Both white male Christians simply cannot be considered terrorists.
Fascinating. And the way that the media constantly shoves every detail in our face has nothing to do with it, either.
Good morning @banasy
Media revels in such stuff.
Why was my earlier post not published?
funny how every murder is linked to lack of gun control or blamed on video games. millions of people play video games and the majority dont go out to kill people(in life). and guns cant fire themselves. why do we have to fetch for a reason for these things. the individual is the problem. im sure most murders and criminals live in a building of some type, maybe the inanimate structure made him do it
There's a new study that links violent video games with the propensity for aggression and violence. Google it.
linking somethin in a study is not proof. its another name for a statistic which is usually clouded by the researches tunnel vision on what he/ she would like to find. to base all science on statistics instead of proof and facts is to basing everything on the results of family fued
Problem is with people. However if you can control selling guns to such people, you can do some nonzero good. Cant understand why people don't get such a simple logic
there is a lot of violence going on today and this is far worst then anything I cried for several days and was depressed as well I pray for the childrens family. this is not about obession. its about copy cats
im sorry I cant speak of this any longer .it makes me so sad and this feeling will always scar me for life
this is lack of guardianship, no positive rolemodels
As obaman would put it it was the result of Bush failed policy
CNN has YET to explain why they used a piece of video footage that was NOT from the Sandy Hook school, but was instead from the St.Rose of Lima School in Newtown, and could NOT have been shot on the same morning – because THE ST.ROSE CLIP WAS SHOT IN LATE AFTERNOON! That means they already HAD the St. Rose clip showing a bunch of brown-uniformed police running toward the building, but used this footage – "stock" or "file" footage, or whatever, without telling the public that it was not real footage from Sandy Hook!
This was aired during the day on 12/14, so the footage in question was shot NO LATER THAN the day BEFORE the shooting. Why did they even have such footage, and why was it used? It is obviously late afternoon footage, as the shadows are very long and point toward the EAST – which means the sun was LOW in the WEST.
CNN IS LYING TO US!
What? I guess you'll be saying sandy hook never happened. You're the first person I've read that said that, which is good because that means you are the only nut spreading this nonsense.
do you have a point here? who the hell cares about shadows and what way the sun was setting?!
@ Ken Margo – agreed
So he was obsessed with mass murders and one murderer in particuar.... Mommy Dearest doesnt think to keep the weapons locked up huh??
