Months after the Newtown tragedy, State Police released a lot of information on their investigation into the Sandy Hook Elementary School shootings and gunman Adam Lanza, but they didn’t release everything, and a court battle between authorities and the media over unreleased documents has ensued.

The Hartford Courant has requested documents which are referenced in the State Police report on the Dec. 14, 2012, shootings, but which haven’t been made public. Lanza, 20, killed his mother, Nancy Lanza, at home, then fatally shot 20 children and six adults inside the school before committing suicide.
