In 2002, Robert Roberson raced his 2-year-old daughter, Nikki, to a hospital emergency room in the east Texas town of Palestine. Nikki was limp, her skin blue. Roberson told the emergency room doctors and nurses that the two had been sleeping when he awoke and found Nikki on the floor, having fallen off the bed. The child was unresponsive. Nikki Curtis never regained consciousness and died a few days later.
