Susan Edwards (55) and her 57-year-old husband Christopher are both set to appear before Nottingham Crown Court from Wednesday 4th June, in a trial that is expected to last for four weeks.
They have denied murdering her parents, William and Patricia Wycherley, between May 1st and 5th, 1998, when they appeared before the court at a hearing in February.
The Wycherleys disappeared from their Blenheim Close home in 1998, but police launched a murder inquiry after human remains were discovered in the back garden of their Forest Town home last October.
The remains were identified through DNA testing and a post-mortem examinations revealed that both had been shot.
At the time the bodies were discovered, neighbours described the Wycherley’s as a reclusive couple.
One resident, who asked not to be named, said: “They made for a funny couple, very quiet and very reclusive.”
The Edwards, of no fixed abode, were arrested at St Pancras International Station in London on October 30th last year.
