good to have you back on new day. online posts linked to the mother of the oregon college shooter have a window into his mental state. those posts are shining a spotlight with the mother and son s bond over guns. joining us is a board certified pediatric psychiatrist. we re so happy to have you here with us. this woman has been a prolific poster online, says she was a registered nurse. we re able to confirm that. she also claims she has asperger s. i just want to talk to you about what we know about asperger s. this has been brought into the conversation. we know it s on the spectrum of autism. it s a developmental disorder. yes. but is there any reason, any science, to link any planned violence to this diagnosis?
