(Newser) – There is a single woman on federal death row, and her execution date has now been scheduled. If Lisa Montgomery is put to death on Dec. 8 as planned, she'll be the first woman executed by the feds since 1953. The New York Times reports the Kansas woman was convicted of strangling Bobbie Jo Stinnett in 2004 and cutting the baby from her body with a kitchen knife. Stinnett, 23, was 8 months pregnant and had advertised a litter of puppies online; Montgomery responded to the ad and traveled to Stinnett's Missouri home. Montgomery, then 36, had told people she was pregnant and tried to pass the baby girl off as her child, though she had in fact undergone a sterilization procedure years prior.
