SA man, 84, denies murdering wife AN 84-year-old man accused of murdering his wife may have been mentally incompetent at the time, a judge has been told. Daniel Dunn was arraigned on Monday in the South Australian Supreme Court, where he sat in a wheelchair and used a listening device because of his hearing problems. He pleaded not guilty to murdering Edith Rose Alice Dunn, 86, on December 29, 2012. She died at their home at Gladstone, in the South Australian mid-north. Details of how the woman died have not been released, but police told an earlier court hearing the alleged murder was "of a violent nature." The crown prosecutor said on Monday that the defence had provided two reports raising the issue of Dunn's mental competency. She conceded it was appropriate for the judge to order a report from an independent psychiatrist. Justice Trish Kelly made the order, adjourned the case to October 25 and continued Dunn's bail. He resides in a special ward at Adelaide's Queen Elizabeth Hospital.
