A possible motive for the shooting rampage at Sandy Hook elementary school was recently revealed.
According to CBS News, law enforcement sources say the shooter Adam Lanza was motivated to kill more people than Anders Breivik.
Breivik killed 77 people in a bomb attack and gun rampage in Norway back in 2011.
However Connecticut authorities are debunking that report.
They say they have not determined a motive for the Sandy Hook massacre and the CBS story was not accurate.
