Lanza 'rarely spoke', recall some who took classes with Sandy Hook gunman

As Americans paused for the one-week anniversary of the Connecticut school massacre, new details emerged about gunman, Adam Lanza, who could take apart and reassemble a computer in a matter of minutes, but rarely spoke to anyone.

In high school, Lanza used to move awkwardly through the hallways, pressing himself against the wall while wearing the same green shirt and khaki trousers every day. He hardly ever talked to classmates and once gave a presentation entirely by computer, not uttering a single word.
