As the media and authorities work
to piece together the biography of Adam Lanza, the gunman in the Newtown, Conn., school shooting, a new report says the 20-year-old spent hours in a windowless basement playing the first-person shooter game Call of Duty.
, a plumber who worked for Lanza's mother, told the U.K.'s Sun newspaper
that the shooter played the violent video game while surrounded by posters of guns used throughout U.S. military history.
"I’m not blaming the games for what happened," he told the newspaper, "but they see a picture of a historical gun and say, 'I’ve used that on Call of Duty.' "
