As Officers Chapman and Smith approached the second classroom in the hallway on their left, they spotted a rifle on the floor. Inside, they found the gunman, Adam Lanza, dead by his own hand, along with the bodies of several children and other adults.

The officers searched the room for any other gunmen, then began searching for signs of life among the children. One little girl had a pulse and was breathing. Officer Chapman cradled her in his arms and ran with her outside, to an ambulance. Officer Chapman, a parent himself, tried to comfort her. “You’re safe now; your parents love you,” he recalled saying. She did not survive.

Most of the bodies were found in the classroom next door, where, Detective Frank recalled, “the teacher had them huddled up like a mother hen — simple as that, in a corner.”
