The sister of Eastern Cape farmer Gideon van Eck, shot dead by his wife of 36 years, Natasha, claims the couple had a long history of arguments.
Van Eck was shot on their Kariega farm on Sunday night. His sister Emmie Posthumus claimed Natasha had tried to shoot him on a previous occasion, but the gun had jammed.
Posthumus described her 60-year-old brother as "a peace-loving Christian".
