Lisa Montgomery – the only female inmate on federal death row in the US – has been executed for murder. She received a lethal injection at a prison in Terre Haute, Indiana, after a last-minute stay of execution was lifted by the US Supreme Court. The case attracted attention because her lawyers argued she was mentally ill and suffered serious abuse as a child. The 52-year-old strangled a pregnant woman before cutting out and kidnapping her baby in Missouri in 2004. Her victim, 23-year-old Bobbie Jo Stinnett, bled to death. Montgomery is the first female federal inmate to be put to death by the US government in 67 years.
