Re: A mother and son will go on trial at Swansea crown court charged with murdering 84 year old Betty Guy.<br />
Mrs Guy died on November 7, 2011, and her body was cremated soon afterwards.<br />
Her daughter, Penelope John, aged 50, and her grandson, Barry Rogers, 32, have previously denied her murder and an alternative charge of manslaughter.<br />
The court has previously heard that the prosecution case involved 75 hours of recorded statements made by the defendants.
