CT Investigators: Adam Lanza Wanted to Outdo Anders Breivik

Say Lanza wanted higher kill count than Norway shooting, was acting out video game fantasies

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.
