NEWTOWN, Conn. - A possible motive in the Sandy Hook massacre might soon be confirmed and released soon, according to officials.
Law enforcement sources told CBS News that 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.
The same sources also said Lanza was obsessed with violent video games.
But Connecticut police said investigators have still not determined a definite motive for Lanza's murders.
