On the evening of 14 November 1984, the body of young mother and housewife Jennifer Tanner was found by her husband Laurie slumped on a sofa in their farmhouse at Bonnie Doon, a tiny hamlet near Mansfield, in Victoria’s high country. It looked as if she had shot herself: there was a gunshot wound in her forehead and a bolt-action .22 rifle between her legs. One of her hands was partly around the barrel. Uniformed police on the scene declared it a suicide, detectives were not called in, no photographs were taken, no forensic tests were done, the place was cleaned up next day – and that was that.
