Michelle Nicholson, who was behind bars for more than a decade for a murder she says she could not prevent, now spends her life supporting the rehabilitation of women who have experienced the criminal justice system. Nicholson claims she was framed for the murder of her father and has published her story in ‘Without a Voice: One Woman’s Fight for Justice’. After leaving prison she set up the Sheffield-based charity Key Changes – Unlocking Women’s Potential. Nick Coleman reports for Sheffield Live!
