FILE - This undated image provided by the Arizona Department of Corrections shows Debra Jean Milke, who has been on Arizona's death row for nearly 20 years for plotting her 4-year-old son's murder. A federal appeals court on Thursday March 14, 2013, threw out the convictions of Milke, sentenced to death in the notorious 1989 killing of her 4-year-old son, ruling that the case was tainted by a detective with a history of lying under oath.
