The burnt body of 70-year-old Merril Kelly was found by firefighters at the Quambatook cemetery in north-west Victoria last year.
The court heard her alleged killer Brian Barnes, 68, developed a desire to kill following a dispute over plumbing works at a volunteer-run public swimming pool at Quambatook, about 300 kilometres north-west of Melbourne.
