The Connecticut Supreme Court ruled 5-0 Tuesday morning that the state police must release documents belonging to the mother of Sandy Hook Elementary School shooter Adam Lanza. The ruling overturns a lower court ruling.

Many of the document in question belonged to Adam Lanza, including a spiral-bound book written by the shooter titled “The Big Book of Granny,” a photograph of the school’s class of 2002-2003, and a spreadsheet of rankings of mass murders, which also included the names, number of people killed and weapons used.
