On this date in 1986, 22-year-old Mary Neilson visited a house on Moorhouse Street in Perth to buy car tyres advertised for sale. The advertisement was a trap. David and Catherine Birnie held her captive before taking her to nearby bushland, where they murdered her.
Mary was the first of at least four women killed by the couple over the following weeks. Their killing spree ended when a later captive escaped and alerted police, exposing the Birnies’ crimes and leading to their arrest.
John Jones, a hutkeeper on a station near Mount Joy in South Australia’s remote Eyre Peninsula, was found dead in his hut in May 1860, his skull broken and the hut stripped of flour, tea and clothing. The accused was convicted at the Supreme Court in Adelaide largely on the testimony of a young companion who admitted taking part in the killing himself.
Before the execution, around 400 citizens, headed by the Lord Bishop of Adelaide, signed a memorial asking the government to remit the death sentence. He had been tried and condemned under British law newly imposed on his people, with little understanding of its workings; the petition failed regardless. He was taken back across the Eyre Peninsula and hanged at Streaky Bay on 5 October 1860, near the district where the killing had occurred
George Dean had already escaped the gallows once, pardoned after a Royal Commission cast doubt on the poisoning case against his wife, Mary. Then a North Shore chemist named Smith came forward, admitting he had sold Dean arsenic and strychnine after Dean claimed he needed a double dose and two poisons to deal with rats on his property.
On 5 October 1895 detectives approached Dean just as he stepped off his ferry at Sydney‘s Circular Quay, still dressed in his captain’s uniform, and arrested him again. “I wonder how many more times I shall be arrested over this affair,” he remarked, before going with the detectives.
Dean subsequently confessed in writing to poisoning his wife. He was convicted of perjury committed to procure his own acquittal and sentenced to fourteen years, while his former lawyer and others faced charges of conspiring to pervert the course of justice.

In October 1993, a local man out gathering firewood stumbled on human remains in a remote corner of Belanglo State Forest. The bones belonged to Deborah Everist and James Gibson, a Melbourne couple missing since 1989.
What unsettled investigators was that Gibson’s camera and backpack had already turned up years earlier, dumped by the roadside at Galston Gorge, more than 120 kilometres from where his body finally lay. Within weeks, a wider search of the forest uncovered four more young backpackers buried nearby, confirming Belanglo as the burial ground of a serial killer.
