Martha Rendell, de facto wife of Thomas Nicholls Morris, was convicted in the Supreme Court of Western Australia at Perth of the wilful murder of her partner’s son, Arthur Joseph Morris, and sentenced to death by hanging. The court accepted that Thomas Morris had been unaware of what Rendell was doing until after the deaths of the children, and he was acquitted.

Acting Chief Justice Robert McMillan told the jury it was probably the most anxious case he had ever presided over, and voiced concern that newspaper coverage, might have prejudiced their judgement. Rendell maintained her innocence throughout, insisting she had only been treating the children for diphtheria.

Two men were convicted of killing Margaret Ann Impett at Mount Wedge station in South Australia. Rather than being executed at the remote spot where the crime occurred, they were hanged at the Chiriroo police station near Venus Bay on Saturday, 14 September 1861, in front of a large gathering, where both men admitted their guilt.

Authorities had decided against transporting the condemned men the 20 to 30 miles to the actual murder site, citing a lack of available conveyance, a decision that left the execution taking place far from where Margaret Impett had died.

Her husband later wrote a furious public letter demanding to know why the men had not been executed on the spot, as he understood a recently passed law required. He branded the failure to enforce it a farce, asking who had dared to disregard the law of the land.

Nine week old Azaria Chamberlain vanished from her family’s tent at a campsite near Ayers Rock on the night of 17 August 1980. Her mother, Lindy Chamberlain, said she had seen a dingo leaving the tent, and the baby’s blood stained jumpsuit was found nearby days later, but her body was never recovered. A first inquest in 1981 accepted the dingo account and found no evidence of foul play.

That finding was overturned on appeal, and a second inquest opened on 13 September 1982, reopening a case that had already divided the country. This inquest went the other way, committing Lindy Chamberlain for trial on a charge of murder, a reversal that would send her to prison and make her one of the most publicly vilified women in Australian history.

Lindy Chamberlain was convicted later that year and sentenced to life imprisonment, but the case unravelled in 1986 when a piece of Azaria’s matinee jacket was found near a dingo lair, corroborating the original account. She was released and eventually exonerated, and a fourth inquest in 2012 formally confirmed that a dingo had taken and killed the child.

On Friday 13th September 1973, 20-year-old David McGreavy was left babysitting the three Ralph children in Worcester while their parents were out. He killed all three.

McGreavy then took a pick-axe to the bodies before impaling the remains on the wrought iron fence spikes of the house next door, where they were discovered by neighbours. The killings, carried out on the date now inseparable from bad luck and horror folklore, later fed the case’s grim nickname as Britain’s real life Friday the 13th murders. McGreavy was convicted and given three life sentences.
