Lisa Montgomery will become the first federal female inmate to be executed in the US in 67 years.
She was sentenced to death after committing the sickening crimes of murdering a pregnant woman, carving the unborn child out of her womb, and kidnapping the baby in 2004.
Her death will mark the eighth federal execution in the US this year after President Donald Trump’s administration restarted them after 17 years.
The attorney general, William Barr, said the crimes were “especially heinous murders”.
Meanwhile, Montgomery’s lawyers argued she had been suffering from delusions when she killed Bobbie Jo, but a jury rejected her defence.
Who is Lisa Montgomery?
Lisa Montgomery, 43, is a murderer who is currently in prison in Indiana, US.
She was sentenced to death for her horrendous crimes.
Justice Department officials have said Montgomery will be executed by the state at US Penitentiary Terre Haute in Indiana.
Montgomery murdered 23-year-old Bobbie Jo Stinnett while she was pretending to be pregnant.
She approached Bobbie Jo online, posing as Darlene Fischer, saying she wanted to buy a dog.
The two women arranged to meet on December 16, 2004, so Montgomery could buy a rat terrier from Bobbie Jo.
Montgomery arrived at her victim’s home in Skidmore and strangled her with a neon pink rope.
The twisted killer then carved the baby from the victim’s womb and attempted to pass the child off as her own.
She was eight months pregnant at the time.
Montgomery claimed at her trial that she was sexually abused during her childhood, which led to mental illness.
She will be put to death by lethal injection on December 8.
The baby, whose name is Victoria Jo Stinnett, survived the attack and is now 16.
