While talking to the British journalist, Routier maintained her innocence and said she "didn't do this."
She said during the interview: "I’m at peace with myself. I didn’t do this. I did not murder my children, I did not attack myself.
"If they choose to kill me, that’s my innocent blood that will be on their hands."
Her husband, Darin Routier - who also alleges the children's killings were carried out by an intruder - said there is an innocent woman on death row, reported.
He said: "They convicted Darlie on character assassination and if we start doin' that in our criminal justice system, then everybody's gonna be guilty."
There are no eyewitnesses and no other confessions while Routier continues to maintain her innocence.
