A Connecticut judge has ruled that state police do not have to release documents belonging to Adam Lanza that were seized from his home after he killed 20 first-graders, six educators and himself at Sandy Hook Elementary School in 2012.

Judge Carl Schuman overturned a decision by the state Freedom of Information Commission, which ordered state police to turn over the documents to The Hartford Courant under a public records request. The ruling on Friday was first reported by the Republican-American.

The requested materials included a spreadsheet ranking mass murders and a notebook including a story about a character who shoots people and another who likes hurting children.

The judge ruled that state law shields from public disclosure all seized property not used in criminal prosecutions.
