In this episode, Alex talks to Sabrina Butler Smith, the first woman to be exonerated and freed from death row in the United States. Sabrina was sentenced to death for the murder of her baby son Walter. After he stopped breathing, she had rushed him to hospital. Walter died the next day and Sabrina was arrested due to the bruises left by her resuscitation attempts. Eight years later, after a retrial, she was released from prison, and today, Sabrina campaigns for the abolition of the death penalty and is still trying to get Walter's official cause of death changed from 'murder'. The Innocents is presented by Alex Hannaford and produced by Peter Sale
