HARTFORD, Conn. — Adam Lanza’s parents and educators contributed to his social isolation in the years before he carried out the Sandy Hook Elementary School massacre in 2012 by accommodating – and not confronting – his difficulties engaging with the world, according to a state report issued Friday.

The Office of the Child Advocate, which investigated Lanza’s upbringing to glean lessons for preventing future tragedies, concluded that Lanza’s parents, education team and others missed signs of how deeply troubled he was and missed opportunities to steer him toward more appropriate treatment.

Lanza killed his mother, then shot his way into the school in Newtown on Dec. 14, 2012, and gunned down 20 children and six educators before committing suicide.

Lanza’s obsessions with firearms, death and mass shootings have been documented by police files, and investigators have concluded that the motive for the shootings may never be known.

In exploring what could have been done differently, the new report homed in on his mother, Nancy Lanza, who backed her son’s resistance to medication and, from the 10th grade on, kept him at home, where he was surrounded by firearms and spent long hours playing violent video games.

“Mrs. Lanza’s approach to try and help him was to actually shelter him and protect him and pull him further away from the world, and that in turn turned out to be a very tragic mistake,” said Julian Ford, one of the report’s authors, at a news conference.


The authors said Lanza’s parents tried to get help for him in variety of ways, but they did not know which path to take and appeared not to grasp the depth and severity of his disabilities. His parents were divorced, and Lanza had not seen his father for two years. After 2008, his parents did not appear to seek any mental health treatment for him, and there was no sustained input from a mental health provider after 2006, according to the report.

The one provider that seemed to understand the gravity of his condition, the Yale Child Study Center, evaluated him in 2006 and called for rigorous daily therapy and medication for conditions including anxiety. At the time, a Yale psychiatrist warned there was risk to creating a “prosthetic environment which spares him having to encounter other students or to work to overcome his social difficulties,” according to the report.

The day after the evaluation, Nancy Lanza told the doctor by email that her son would not agree to any sort of medication and that he had been angered by the doctor’s line of questioning. The recommendations went largely unheeded.

In the eighth grade, Lanza was placed on “homebound” status, though he later returned before finishing high school through a combination of independent study, tutoring and college classes. Along the way, the report said, there was no indication that the Newtown school system or the pediatrician coordinated with service providers regarding Lanza’s mental health needs, according to the report, which referred to Lanza as “AL.”

“Records indicate that the school system cared about AL’s success but also unwittingly enabled Mrs. Lanza’s preference to accommodate and appease AL through the educational plan’s lack of attention to social-emotional support, failure to provide related services, and agreement to AL’s plan of independent study and early graduation at age 17,” wrote the report’s authors.

Joseph Erardi Jr., the superintendent Newtown schools, said the report will have great meaning if “there is one school leader, one district, one mental health provider or one set of parents who reads this work and can prevent such a heinous crime.”

The report also provocatively asks whether a family that was not white or as affluent as the Lanzas would have been given the same leeway to manage treatment for their troubled child.

“Is the community more reluctant to intervene and more likely to provide deference to the parental judgment and decision-making of white, affluent parents than those caregivers who are poor or minority?” the report said.

Despite disturbing, violence-laced writings that came to the attention of teachers, investigators say there is no evidence Lanza displayed tendencies for violence or aggression.
