Iris Daphne Temperley (née Donovan) was born at Springsure, Queensland, on 2 March 1927. She married Gordon Temperley in 1949 and the couple had five children. After managing a cattle property north of Duaringa, the family moved to Rockhampton in 1959, settling in a house on George Street. By the time of her death, Temperley had 11 grandchildren and nine great-grandchildren.
On the morning of 26 January 2010, Temperley was raking leaves in the backyard of her George Street home when she was attacked by 18-year-old David Samuel Aubrey Ray. Ray had stolen alcohol from the Leichhardt Hotel prior to the assault and went on to commit a burglary at a neighbouring house afterward. Using a fire extinguisher, Ray inflicted severe injuries on Temperley, including skull swelling, a broken nose, fractured ribs, a fractured sternum, a collapsed lung, and genital tearing that caused profuse bleeding. She was admitted to the intensive care unit at Rockhampton Hospital in critical condition before being flown to the Royal Brisbane and Women's Hospital, where she died on 3 February 2010 without regaining consciousness.
The attack caused significant anger and distress within the Rockhampton community. A public memorial held at St Paul's Cathedral was attended by more than 100 people. Robert Schwarten, the local Member for Rockhampton, said the case had brought "disbelief, revulsion, anger and fear" to the community.
Ray turned himself in at the Rockhampton Police Station on 27 January 2010, accompanied by a relative, admitting to assaulting an elderly woman while claiming difficulty recalling specific details. He was arrested and charged with murder, rape, and property offences including stealing and burglary. Following a mention in the Rockhampton Magistrates Court in September 2010 and a three-day committal hearing in November 2010, magistrate Annette Hennessy committed Ray to stand trial for rape and murder.
At his trial in the Rockhampton Supreme Court in September 2011, Ray pleaded guilty to one count of murder and two counts of rape, receiving life sentences, with an additional 15 years added for burglary and other offences. A psychiatrist's report noted genuine remorse and a long-standing substance abuse problem, but Justice Duncan McMeekin found no psychiatric excuse for the crime, describing the facts as "appalling" given Temperley was "a frail elderly lady of 82 years."
Ray successfully appealed, and the Queensland Court of Appeal reduced his rape sentence to 14 years and his burglary sentence to three years, both to be served concurrently with his life sentence for murder.
In 2020, Temperley's name was added to The Red Heart Campaign, an online memorial honouring women and children who died as a result of violence. As of April 2023, Ray remained incarcerated at the Capricornia Correctional Centre. Temperley's nephew, Vern Donovan, wrote about her death in his autobiography, noting the effect it had on his elderly mother, Merle Donovan, who was close to Temperley.
