HOUSTON (AP) - A 7-year-old boy has died after authorities say he was shot by a married couple who thought he and others who were off-roading were trespassing on their property. Liberty County Sheriff's Cpl. Hugh Bishop said Donald Coffey Jr. died Saturday morning, less than two days after he was struck in the head with a shotgun blast. The boy, his father, his 5-year-old sister and a family friend were off-roading outside of Houston late Thursday when they were shot after stopping their vehicles so the children could go to the bathroom. Donald Coffey Sr. had a pellet wound in his right shoulder. Coffey's daughter, Destiny, was hit in the elbow but was in good condition. A hospital spokeswoman said 30-year-old Patrick Cammack, the family friend, was upgraded from critical condition after being shot in the head.
