 A Missouri woman has walked out of prison after serving 43 years on a now-overturned murder conviction. CBS's Michael Toscano says she was released over the objections of the state's attorney general. Sandra Hemi left the Chillicote Correctional Center, but only after a judge threatened to hold the attorney general's office in contempt if they continued to try to stop it. Hemi had been serving a life sentence after she was twice convicted of the 1980 murder of a library worker, Patricia Jeske. The judge overturned the conviction over a month ago.
