NEWTOWN, Conn. (AP) - Adam Lanza was an awkward, peculiar kid who wore the same clothes to school every day.
He rarely spoke and once gave a school presentation entirely by computer, never uttering a word.
Those are among the new details that emerged Friday, as the nation paused for a moment of silence to mark one week since Lanza slaughtered 20 first-graders and six women at Sandy Hook Elementary School in Newtown, Conn.
Lanza also fatally shot his mother that day and committed suicide.
Former high school classmate Daniel Frost says Lanza liked tinkering with computers and seemed to enjoy playing a violent video game. He says Lanza chose a military-style assault rifle as one of his weapons for the game.
Authorities say Lanza used a military-style assault rifle in the massacre.
