Nancy Lanza, mother of the Adam Lanza, 20, was, according to friends, a paranoid survivalist who believed that the world was on the verge of economic collapse. She was what people call a “prepper”, a person who is preparing for the end of civilized society.
She reportedly became obsessed with guns and taught both her sons – Ryan and Adam – how to shoot. Adam used the knowledge his mother had given him to kill her along with those he murdered at Sandy Hook Elementary School. Adam Lanza shot his mother four times in the head, then went onto Sandy Hook Elementary to continue his massacre.
