A North Carolina woman, who last September was convicted of killing and dismembering her disabled 10-year old stepdaughter, pleaded guilty to an additional federal drug charge today. Elisa Baker‘s stepdaughter Zahra Baker—a cancer survivor originally from Australia—was found dismembered in Caldwell County in 2010. The 43-year-old was later charged with helping to distribute as many as 50,000 prescription pain and anxiety pills between 2006 and 2010, including 22,000 doses of OxyContin and hydrocodone and 29,000 doses of Alprazolam. In return for her entering a guilty plea for conspiracy to sell drugs, prosecutors agreed to drop six other related charges. No sentencing date has been set, but Baker faces up to 20 years in prison and a million dollar fine, in addition to her existing 18-year sentence for the murder of her stepdaughter.
