1952: Australia’s First Thallium Poisoning Murder Conviction: Yvonne Fletcher Sentenced to Death in Sydney

At the Central Criminal Court in Sydney, 30-year-old Yvonne Gladys Fletcher of Newtown was sentenced to death after a seven-day trial for the 1948 murder of her first husband, Desmond George Butler, who died after months of wasting illness caused by thallium poisoning. Asked if she had anything to say before sentence was passed, she replied simply, “No, your Honor,” but moments later a prayer book she had carried through every day of the trial crashed to the floor and she collapsed in the dock, sobbing, as police lifted her out.

Mr Justice Kinsella told the court the crime was “horrible” because the poison had been “secretly administered within the family circle” to an unsuspecting victim, destroying him “mentally and physically while permitting him to linger for months in wretched agony.” Fletcher was the first person in Australian criminal history convicted of murder by thallium poisoning, and the jury recommended that the sale of the poison to the public be banned outright.

What the sentencing did not reveal to onlookers was already known to the court: Fletcher had also been committed for trial over the death of her second husband, who had died from the same poison at Newtown only months earlier. The Crown Prosecutor noted the chilling parallel between the two cases, telling the jury, “There is no question that both Butler and Fletcher died from thallium poisoning… the same matrimonial discord, the same hatred towards each man, the same sudden illness, and the same dreadful symptoms.” The judge himself observed that had this conviction concerned her second husband, evidence of his cruelty toward her might have offered some mitigation, but no such excuse existed for the killing of her first.

1986: Carved with a Scarlet Letter: The Unsolved Murder of Beth Barnard on Phillip Island

In the early hours of September 23, 1986, 23-year-old penguin parade worker Beth Barnard was found stabbed to death in a house on Phillip Island, Victoria. A blanket had been placed over her body, but beneath it her throat had been cut, her nightgown pushed up, and her body slashed and stabbed repeatedly, with defensive wounds on her hands. Cigarette butts and a knife lay near the body, and bloodied paper towels were stuffed around the bathroom sink.

Carved into her chest was a knife wound resembling the letter A, leading some to dub the killing the Scarlet Letter murder. Barnard had been having an affair with her married employer, Fergus Cameron, a founding shareholder of the Phillip Island Grand Prix. The night before her body was found, his wife, 36-year-old Vivienne Cameron, learned the truth and smashed a wine glass across his head and back before driving him to hospital.

Fergus spent that night at his sister’s house while Vivienne asked friends to mind their two young sons. She then vanished and was never seen again. A coroner later found that Vivienne had contributed to Beth Barnard’s death and concluded that she had taken her own life by jumping from the nearby San Remo Bridge, although her body has never been recovered.

1913: The Last Man Hanged in Queensland Walks to the Brisbane Gallows

Ernest Austin was the last person ever executed in Queensland. The 23-year-old farm labourer was hanged in Brisbane in September 1913 for a murder committed at Samford three months earlier.    Reporters noted that the brilliance of the spring morning made it hard to grasp what was happening a few yards away. A chaplain led the procession to the scaffold, reciting the burial service. The condemned man looked in remarkably good health; his appetite had stayed “voracious to the very last”, and he had gained 28 pounds in gaol.    Asked if he had anything to say, he spoke in low, clear tones, waving his right hand for emphasis: “I say straight out that I quite deserve this punishment.” As the white cap was drawn over his face he added: “Send a wire to my mother.”

1976: Rejected From a Model Plane Club, He Opened Fire on the Streets of Spring Hill in Brisbane

On 22 September 1976, 36-year-old William Robert Wilson opened fire on Boundary Street in Spring Hill, a suburb of Brisbane. Armed with a .22-calibre rifle and 500 rounds of ammunition, he killed two teenage girls and wounded four other people. He had reportedly been upset after being rejected for membership by a model plane club.

Wilson then fled to a house in nearby Kelvin Grove and took five student teachers hostage. After around two hours of negotiations, one hostage escaped by pretending she needed the bathroom. Police stormed the house around 4pm, exchanging gunfire with Wilson before overpowering him and freeing the remaining captives.

Wilson spent three years in Hospital before being considered fit to plead. On 23 June 1980, he pleaded guilty to two murders and four attempted murders, receiving two life sentences and concurrent ten-year prison terms.
