HARTFORD (AP) — Police must release disturbing writings and other belongings of the Newtown school shooter to the public because they are not exempt from the state’s open record laws, the Connecticut Supreme Court ruled Tuesday, October 23.

The justices issued a 5-0 decision in favor of The Hartford Courant and state Freedom of Information Commission, whose order to police to release shooter Adam Lanza’s belongings had been overturned by a lower court judge. It’s not immediately clear when the items will be released.

Lanza, 20, fatally shot 20 first-graders and six educators at Sandy Hook Elementary School on December 14, 2012, after killing his mother at their Newtown home. He fatally shot himself as police arrived at the school.

The motive for the shooting has never been made clear. A report by the Connecticut Child Advocate said Lanza’s severe and deteriorating mental health problems, his preoccupation with violence and access to his mother’s legal weapons “proved a recipe for mass murder.”

State police searched the Lanza home and seized guns, ammunition and his belongings, including his personal journals.

Among the belongings were a spreadsheet ranking mass murders and a notebook titled “The Big Book of Granny.” The notebook contains a story that Lanza wrote in fifth grade about a woman who uses her “rifle cane” to kill people at a bank, hockey game and Marine boot camp.

The book also contains several chapters with the adventures of “Dora the Beserker,” influenced by a popular children’s television show. When Granny asks Dora to assassinate a soldier, she replies: “I like hurting people ... Especially children.” In the same episode, Dora sends “Swiper the Raccoon” into a day care center to distract the children, then enters and says, “Let’s hurt children.”

State police already have released some of Lanza’s writings, along with thousands of pages of interviews, documents and other evidence from the investigation. But the full contents of the spreadsheet and the “Granny” notebook have not been released.

The Courant requested to view 35 items seized from the Lanza house, but state police rejected the request citing privacy rights under the state’s search and seizure law.

The newspaper appealed to the Freedom of Information Commission, which ruled the belongings must be released to the public because the search and seizure law doesn’t specifically bar documents seized from people’s homes — and not used in prosecutions — from being released to the public. State police appealed to Superior Court, where Judge Carl Schuman agreed with state police and overturned the commission’s ruling.

Andrew Julien, publisher and editor-in-chief of the Courant, said Lanza’s belongings are important for understanding mass shootings.

“Understanding what a mass killer was thinking not only paints a clearer picture of the individual, it helps us identify and understand red flags that could be part of a prevention formula for future mass shootings,” he said Tuesday.

The state attorney general’s office, which represented state police, declined to comment Tuesday. The office could ask the state Supreme Court to reconsider its decision or possibly appeal to the US Supreme Court.

State police officials did not immediately return messages seeking comment.

Justice Raheem Mullins wrote in the unanimous decision that the court must “narrowly construe” language in state law that allows exceptions to public disclosure, “otherwise any statute governing an agency’s general treatment of records becomes a possible restriction on disclosure.”

“The trial court pointed to nothing in the express terms of the search and seizure statutes that creates confidentiality in the documents or otherwise limits the disclosure, copying, or distribution of the documents,” Justice Mullins wrote. “Indeed, the search and seizure statutes are silent on the issues of confidentiality, copying, or disclosure to the public.”

The Newtown Bee has filed a Freedom of Information appeal with the Connecticut State Police seeking the previously held materials referred to in this AP report.
