Sorrel King uses anguish over child's death to try to cut deadly medical errors.

After her 18-month-old daughter Josie died after a series of medical mistakes, Sorrel King turned the consuming grief of her daughter's death into a crusade aimed at eliminating these sorts of deadly errors.

She has written "Josie's Story: A Mother's Inspiring Crusade to Make Medical Care Safe," and was on the "Today" show this morning to talk about it.

Each year, medical errors claim the lives of about 98,000 patients. We applaud Sorrel King for turning her anguish into action and trying to save lives.
