Adam Lanza was never officially diagnosed with Asperger syndrome. This news article officially states that Adam Lanza's mother and brother merely speculated that he had Asperger syndrome, and that he didn't have a confirmed diagnosis of Asperger syndrome.

Furthermore, Dr. Elizabeth Laugeson, an autism specialist at UCLA stated that "The vast majority of people with Asperger's are law-abiding citizens that don't act violently against others. I think it would be [b]sad to vilify a community because of the action of one person who hasn't been confirmed to have the diagnosis."[/b] There is no way that someone with Asperger syndrome or autism could have POSSIBLY carried out a mass shooting at an elementary school, or anywhere else. Nor could a person with Asperger syndrome or autism have shot a 6-year-old over 60 times People with Asperger syndrome are far too benign, pacifistic, and empathetic to go on mass shootings. As a clinical psychologist who as worked with ppl w Asperger's and autism, I KNOW THIS!!!! Also, refer to this article:http://www.healthzone.ca/health/article/633688
Most likely, Adam Lanza was either a psychopath or a paranoid schizophrenic, and many articles have indicated that he could have been both. Highly conceivable.
