Newtown school massacre: Adam Lanza 'motivated' by Norway massacre Police sources briefed on the Newtown investigation reportedly told CBS that Lanza was obsessed with Breivik and wanted to exceed his death toll. Lanza targeted nearby Sandy Hook Elementary School because it was the "easiest target" with the "largest cluster of people." Once the police arrived, he killed himself. The report said they found a "trove" of video games from the basement of Lanza's home, where he would spend countless hours alone in a private gaming room with the windows blacked out, honing his computer shooting skills. A Connecticut state police spokesman dismissed the report as inaccurate speculation. Lanza killed 20 schoolchildren aged 6 and 7 plus six adults who worked at the school, shocking the United States and leading President Barack Obama to propose new gun control legislation. Authorities have not publicly spoken of his motive. All of it is speculation. There is no basis to the CBS story. We have not established a motive. It's inaccurate," Connecticut State Police Lieutenant Paul Vance said in a statement read on CNN. Breivik, a self-styled warrior against Muslim immigration, killed eight people by bombing the Oslo government headquarters and then shot dead 69 people at the ruling party's summer youth camp.
