 After serving more than four decades in prison, a Missouri woman was freed Friday when her murder conviction was overturned against the wishes of state prosecutors. The Innocence Project says 64-year-old Sandra Haim was the longest held wrongly incarcerated woman in the U.S. Attorney Sean O'Brien fought for years to win her release. It was too easy to convict an innocent person. She was serving a life sentence for the fatal stabbing of a library worker.
