Charles Gleeson was cook at a shelling station on Prince of Wales Island in the Torres Strait, and Patrick McKiernan, by his own later account, was the only man there he actually liked. That did not stop him shooting McKiernan dead with a stolen shotgun one Wednesday morning that May, then wandering the bush armed until Water Police talked him into surrendering, backed by a settler on horseback who held him at gunpoint.

Gleeson was quiet and composed when brought before a magistrate, offering no reason for the killing. He was convicted and hanged in Brisbane on 24 October 1892, sharing the scaffold with William Moncado, condemned separately for the murder of a ship’s boy at Thursday Island; witnesses said Gleeson twitched convulsively for ten minutes before he died.

“Poor Paddy, the only man on the station that I liked, and now I have shot him,” he said when shown the body, the closest thing to an explanation he ever gave.

Dennis Nilsen’s trial opened on this day in 1983, more than a year after police finally traced human remains blocking the drains outside his London home. He had preyed on homeless and vulnerable men he met in pubs, luring them back to his flat before killing them, and once arrested he confessed with chilling thoroughness, filling fifty notebooks with the details of his crimes.

Charged with killing 15 men, Nilsen entered a plea of not guilty by reason of diminished responsibility as proceedings began, arguing that a disturbed mental state, not deliberate will, lay behind the killings.

George Dean, captain of a Sydney harbour ferry celebrated for pulling drowning passengers from the water, was sentenced to death in 1895 for poisoning his wife, Mary, with arsenic and strychnine hidden in lemon syrup and tea. No one could prove he had ever bought the poison, and a public outcry over the verdict forced a Royal Commission, which found the evidence wanting; Dean walked free with a pardon that June.

The relief did not last. His own lawyer admitted to a former Chief Justice that Dean had privately confessed his guilt, and a North Shore chemist came forward swearing he had sold Dean the poison himself, with no entry ever made in the sale book. Dean was arrested again and confessed in writing.

On 24 October 1895 he was convicted of making a false declaration and sentenced to five years. The following day a second conviction, for perjury committed to procure his own acquittal on the capital charge, added fourteen years, the terms to run concurrently.

Leonardo Moncado was a Chilean sailor aboard the trading schooner Sketty Belle when he killed a young cabin hand known as Bob during a voyage off Thursday Island. No trace of the victim was ever found except a mutilated portion of his body, discovered stuffed inside Moncado’s own trunk. One crewman who witnessed the victimes final moments stayed silent for months, having been threatened by Moncado, and only told police the truth once Moncado was committed for trial.

Moncado was convicted of murder and hanged in Brisbane on this day in 1892, attended on the scaffold by a Catholic priest.
