A pit bull had mauled a 3-year-old boy and was biting the youngster's mother when a passing motorist stopped to see what was going on. Corey Kelley said that at first he thought Shonda Busby was playing with the dog in the family's rural yard in Chatom, Ala. He turned his truck around for another look and saw blood. "The closer I got to her, I could see the blood and bite marks on her arms. I pulled up and said, Are you alive?' She said, 'Yes, get this dog off me. He's biting me; he's killing me.'" Kelley quickly drove home, called 911 and grabbed his .22caliber rifle. Unaware that Busby was shielding her 3-year-old, her rescuer said he drove as close as he could, about 8 feet away. From his truck, he aimed at the dog and told Busby to lie as still as she could. "Shoot!" she told him. Kelly's mortal shot hit the animal between the eyes. When Busby sat up, Kelley saw the little boy; his scalp was torn and there were bite marks all over his body. Following the tragedy, the child was treated at Children's Hospital and was in fair condition. His mother required surgery. Kelley said he did not feel like a hero. "I'd do it again in a heartbeat," he said. "I'm just an old country boy. Helping people is just something I like doing."
