A forum dedicated to any info you can dig up on him:
For now he remains somewhat of a mystery and no one is really talking about him. Meanwhile, Gun Control is getting all the attention:
How often did Lanza play the most violent games? How did he feel about them? How did they affect him? Did they desensitize him to violence or provoke blood lust? We don’t know, and most likely never will.
Did he really have Asperger’s? Was he diagnosed with anything in addition to the “developmental disorder” — or was that just a palatable-sounding phrase his family and family friends used to avoid invoking scarier, more threatening terms like “mental illness”? We don’t know what lay behind the extremely inward-turned behavior his classmates saw, or the murderous violence that erupted last week. Was it extreme, toxic anxiety? Paranoia? Voices? Righteous rage? We may never know.
