is reporting two unnamed police officials told the network, Lanza's motive in the mass murder of 20 children and six adults at Sandy Hook Elementary School in Newtown, Connecticut last Dec.14, was to top Norwegian mass murderer Anders Breivik.
The sources also claim that Lanza picked the school because it was "easy" and because there were a lot of people in a confined space.
CBS is also claiming that in addition to Lanza accompanying his mother to shooting ranges, it is believed he practiced shooting on his computer. He spent hours playing violent video games in a room in his home in which the windows were blacked out. It is also reported he had a "trove" of violent video games and may have been acting one out when he went on the shooting spree.
As the Daily Mail
reports, on July 22, 2011 Breivik set off a car bomb in downtown Oslo killing eight people. He then went to an island where a summer camp run by Norway's Labor Party was located and shot 69 people to death. Most of the dead were young people. In both incidents, 237 others were injured. Breivik was eventually sentenced to 21 years in prison although this term can be extended.
Unlike Breivik who surrendered to police, Lanza killed himself when first responders first entered the school.
The Connecticut State Police are denying the content of the CBS report. Lieutenant Paul Vance issued a statement
saying, " All of this is speculation. There is no basis to the CBS story. We have not established a motive."
Police have never officially released a motive for the mass killing.
