The Sandy Hook Elementary School shooting occurred on December 14, 2012, in Newtown, Connecticut, when 20-year-old Adam Lanza fatally shot 20 children between 6 and 7 years old, as well as six adult staff members. Prior to driving to the school, Lanza shot and killed his mother at their Newtown home. As first responders arrived at the scene, Lanza committed suicide by shooting himself in the head.
A November 2013 report issued by the Connecticut State Attorney's office concluded that Lanza acted alone and planned his actions, but no evidence collected provided any indication as to why he did so, or why he targeted the school.
Lanza was diagnosed with a sensory-integration disorder at the start of elementary school. When he was thirteen he was diagnosed with Asperger syndrome by a psychiatrist, according to his father, Peter Lanza. Adam also had obsessive-compulsive disorder, being referred in October 2006 for treatment for his conditions, when behavioral-based therapy and the antidepressant Celexa were prescribed. Following objections from Nancy Lanza, the treatment was discontinued after four visits, and Lanza stopped taking the medication.
Lanza was fascinated with mass shootings, most notably the Columbine High School massacre and the Northern Illinois University 2008 shooting. He did not allow anybody in his bedroom (the windows of which he had taped over with black plastic garbage bags to block out sunlight), refused to have a Christmas tree in the house, and would not eat his food unless it was arranged in a particular way on his plate. He had also chosen to cut off contact with both his father and brother in the two years before the shooting and at one point communicated with his mother, who lived in the same house, only by email. A document entitled "Selfish," about the inherent selfishness of women, was found on Lanza's computer after his death.
