Police released thousands of pages Friday from their investigation into the Newtown massacre, providing the most detailed and disturbing picture yet of the rampage and Adam Lanza's fascination with murder, while also depicting school employees' brave and clearheaded attempts to protect the children.
Among the details: more than a dozen bodies, mostly children, were discovered packed "like sardines" in a bathroom where they had hidden. And the horrors encountered inside the school were so great that when police sent in paramedics, they tried to select ones capable of handling what they were about to witness.
"This will be the worst day of your life," police Sgt William Cario warned one.
The documents' release marks the end of the investigation into the December 14, 2012, shooting at Sandy Hook Elementary that left 20 first-graders and six educators dead.
Lanza, 20, went to the school after killing his mother, Nancy, inside their home. He committed suicide with a handgun as police arrived at the school.
