Former nanny Omaima Nelson is scheduled to appear before parole commissioners Wednesday at the Central California Women's Facility in Chowchilla where she has been serving a life sentence.
Nelson was convicted of murdering her 56-year-old husband William Nelson in a grisly killing that authorities compared to the fictional slayings of Hannibal Lecter.
Prosecutors said Nelson killed her husband and likely plotted to steal from him as she had done with other middle-aged men. Nelson said she stabbed her husband to fend off an assault.
A psychiatrist testified during Nelson's trial that she told him she ate her husband's ribs but later denied it.
Nelson was denied parole in 2006 because commissioners found her unpredictable and a serious threat to public safety.
