The only female prisoner, Lisa Montgomery, on federal death row in the United Stated has been put to death under the charges of murder.

It has happened for the first time in 67 years that a female inmate has been sentenced to death by the US federal authorities.

The prisoner was accused of murdering a 23 year old pregnant lady, Bobbie Jo Stinnett and kidnapping her baby in Missouri in 2004 and found guilty of the crime in 2007.

The death was pronounced “in accordance with the capital sentence unanimously recommended by a federal jury and imposed by the US District Court for the Western District of Missouri” and Montgomery put to death by lethal injection of pentobarbital at a prison Terre Haute, Indiana.

She was declared dead at 01 : 31 (06:31 GMT).

Following the capital punishment, Lisa’s counsel said that all the people witnessing the punishment should feel sorry and shame as it was unjust.

Her lawyers argued that she had been born brain-damaged and was too mentally ill to be granted a death penalty. As a child she was routinely sexually and physically abused by her father and trafficked by her mother, family members said. Her treatment was so violent that it amounted to torture.
