Lanza killed 20 children aged six and seven and six adults at Sandy Hook elementary school having previously shot dead his mother Nancy last Friday. He then shot himself dead. Police are still searching for a motive.
It has emerged that Lanza spent his time in the basement of the family’s four-bedroom home in Newtown playing video games, such as Call of Duty and obsessing over guns and military equipment, according to an interview in The Sun with plumber Peter Wlasuk.
Call Of Duty is controversial because of its violent content. The Advertising Standards Authority in the UK banned daytime advertising of the game earlier this year.
