**1. Introduction**

The vast majority of persons with Autism Spectrum Disorders are highly moral but can show aggression of a non-lethal severity. Nevertheless there are a small number of persons with Autism or Asperger's Syndrome who do show lethal violence. I have described these as Criminal Autistic Psychopathy [11]. The rate of these problems in special hospitals and prisons is almost twice the general population prevalence of Autism and Asperger's Syndrome. Originally, these conditions were called Autistic Psychopathy by Hans Asperger 1938 and 1944. [9] I am suggesting that we bring back the diagnosis of Autistic Psychopathy for those persons with Autism and Asperger's Syndrome who engage in criminal activities with the new diagnosis Criminal Autistic Psychopathy. These persons have the dual features of Autism and Psychopathy. The seriousness of this condition is often missed with the sole diagnosis of Autism or Asperger's Syndrome. There are overlapping features but also differences from General Psychopathy as described in these examples of school killers in the literature.

In relation to the school shooting at Sandyhook School, Solomon (214) noted that from his conversation with Peter Lanza that his son Adam who shot 26 people at his school showed poor eye contact, problems with social relationships, preservation of sameness, narrow interests, poor communication skills and sensory issues. These are the classic features of Asperger's Syndrome DSM IV or the sub group of Asperger's Syndrome called Criminal Autistic Psychopathy [11].
