Police Release Documents on Newtown Massacre

Police in Connecticut have released thousands of pages of documents from the investigation into the school massacre in Newtown. They provide the most detailed picture yet of the rampage and of the 20-year-old gunman's fascination with guns and violence.

The paperwork, photos and videos were heavily blacked out to protect the names of children and to withhold some of the more grisly details of the crimes.

The documents released Friday fill in more details about how the shooting unfolded, teachers protected their students and the school janitor confronted the shooter.

Lanza gunned down 20 first-graders and six educators with a semi-automatic rifle at Sandy Hook Elementary School on Dec. 14, 2012, after killing his mother inside their home. He committed suicide with a handgun as police arrived at the school.
