CNN's Nancy Grace reports on the tragic story of the New Mexico boy, 11, who made a frantic 911 call to report that he had shot his father in the back of the head. The shooting was witnessed by his six-year-old sister, according to police. Apparently the boy was angry at his father for being grounded. He initially told the 911 operator that his father was asleep, but then confessed to shooting him. CNN describes the 911 call as "frantic."
