Adam Lanza had a sensory disorder that impeded his ability to process the world around him, a Hartford Courant journalist tells NPR. His Sensory Integration Disorder diagnosis meant "he wasn't able to guide touch and smell and sight," Alaine Griffin says. "He wasn't able to ... process things to do with his senses. And we learn that Nancy was very sad at the fact that he couldn't love her back."
The revelation comes ahead of a Courant/Frontline documentary to air Tuesday; Raising Adam Lanza delves into the shooter's relationship with his mother, Nancy. Griffin explains that "through the reporting we did, we definitely learned more about Nancy and the efforts she went through to give Adam as normal a life as possible as he went from boy to man."
