Lisa Montgomery- the only female inmate on federal death row in the United States, has been executed for murder.
Montgomery is the first female federal inmate to be put to death by the US government in 67 years.
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 lawyer 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.
Police found Montgomery cradling a new-born girl she claimed to have given birth to the day before. After her story fell apart, she confessed to the killing.
She was found guilty of the crime in 2007. The next day, she was sentenced to death.
The latest execution was postponed twice-first by COVID-19, then by a judge-until, a Supreme Court ruling cleared the way for it to take place in the early hours of Wednesday.
