In an interview with ABC in Atlanta, Antoinette Tuff, a bookkeeper at Ronald E. McNair Discovery Learning Academy, near Decatur, Ga., recalled the harrowing ordeal on Aug. 20 during which she was held hostage by a 20-year-old man, Michael Brandon Hill. Hill entered the building during school hours with an AK-47. No one was injured.

"He had a look on him that he was willing to kill," she said. "Matter of fact, he said it. He said he didn't have any reason to live and that he knew he was going to die today. I realized at that time that it was bigger than me. He was really a hurting young man. So I just started praying for him and then just started talking to him."
