A rapist who got a teenager pregnant during an attack has been caged for four years.
even tried to claim her got the 19-year-old pregnant without having sex.
The perverted 59-year-old insisted his diabetes made it "impossible" for him to have intercourse.
Waller instead claimed the young woman had entered into a bizarre agreement between him and his wife that she would have a baby for them in the 1990s.
This was apparently to be done with the help of an ink syringe.
The victim - who has since died - got justice from beyond the grave after Waller was convicted of rape.
He was today sentenced at the High Court in Glasgow.
Lord Armstrong told him: "I note that you continue to deny any responsibility for your criminal actions.
"The crime of rape is a grave one against which all women should be protected."
The trial heard how the young woman knew Waller and his wife.
Jurors heard how she fell pregnant at 19. DNA tests revealed Waller to be the father of the child.
The ex-taxi driver, of Dumfries, claimed in court it was a "shock".
He told jurors: "My wife and the girl had discussed about wanting to bring another child up."
Waller denied having sex with the victim - insisting the pregnancy was instead helped with the aid of "syringe used for printer ink".
His advocate Louise Arrol asked: "Was this agreed by all of you?"
Waller replied: “It was agreed that the child would live with us. She could then claim the child benefit."
He said his wife had previously had a C-section and had been told not to give birth again.
But, prosecutor Jim Keegan QC put to Waller: "You had intercourse with her."
Waller: "Impossible. Physically impossible."
He insisted his diabetes issues had caused problems.
The victim later died due to a heart condition.
