1949: The Acid Bath Murderer: John Haigh Hanged for Six Killings

John George Haigh was an English serial killer who battered or shot his victims, then dissolved their bodies in sulphuric acid to erase all evidence. He forged his victims' signatures to sell their possessions and collect large sums of money, a scheme he had refined through years of fraud and multiple prison terms. Though convicted of six murders, Haigh claimed to have killed nine.

Born in Stamford, Lincolnshire, and raised in Yorkshire by strict Plymouth Brethren parents, Haigh drifted from fraud into murder after becoming fascinated by French killer Georges-Alexandre Sarret, who had used acid to dispose of bodies. He was arrested in 1949 after police connected him to the disappearance of a widow whose remains, including gallstones and false teeth, survived the acid and were found at his workshop in Crawley, Sussex. Haigh was convicted at Lewes Assizes and hanged at Wandsworth Prison on 10 August 1949.

1977: A Parking Ticket Brings Down the Son of Sam

David Berkowitz, a 24-year-old postal clerk from Yonkers, was arrested and charged as the Son of Sam, the .44-caliber killer who had terrorised New York City across 13 victims and more than a year of terror. The break came not from the massive task force that had spent several million dollars and chased hundreds of suspects, including a priest, freelance journalists, and ex-cops, but from a $35 parking ticket issued by Officer Michael Cataneo on the morning of July 31, 1977, the same night Berkowitz claimed his final victim. The ticket was traced to his 1970 Ford Galaxie.

Neighbours in Yonkers had long suspected something was wrong. Sam Carr, who lived on the street behind Berkowitz, believed Berkowitz had shot his black dog Harvey and had complained to police just days before the arrest. Berkowitz later claimed Harvey the dog had issued him mysterious commands to kill. After more than a year of dead ends, the Son of Sam was undone by a piece of cardboard.

1987: The Hoddle Street Massacre: Seven Dead in Melbourne Shooting Rampage

On the evening of 9 August 1987, 19-year-old Julian Knight opened fire on motorists and pedestrians along Hoddle Street in Clifton Hill, a suburb of Melbourne, killing seven people and seriously injuring 19 others. Knight had been discharged from the Royal Military College, Duntroon just 16 days earlier following a fight and stabbing at a bar. He returned home to find his girlfriend had left him and his mother had converted his bedroom. Armed with multiple weapons, he took to the street.

After a police chase lasting more than 30 minutes, Knight was caught in nearby Fitzroy North and arrested. He was later sentenced to seven concurrent life terms, with a non-parole period of 27 years, for what the presiding judge described as 'one of the bloodiest massacres in Australian history'. As Knight neared parole eligibility in 2014, the Victorian Government amended the Corrections Act to prevent his release unless he was in imminent danger of dying or physically incapable of causing harm.

1875: Ah Kat Hanged at Castlemaine for the Murder of Friedrich Renzelmann

Friedrich Renzelmann, a bricklayer living near Dunolly in central Victoria, had long suspected his wife of visiting the hut of a Chinese laundryman known as Ah Kat. One day in early August 1875, Renzelmann feigned leaving for work, concealed himself near the hut, and watched his wife enter. In a rage, he rushed in and struck Ah Kat twice on the head and neck with a chopper before surrendering himself to police.

The follow year, Renzelmann was dead, his battered body found at the bottom of a deep mine shaft on the Bet Bet Reef near Dunolly. When Ah Kat attended a hospital to have head wounds dressed and could not satisfactorily explain them, he was arrested. His wife was also taken into custody pending the inquest.

Ah Kat was tried, convicted of murder, and hanged at Castlemaine on 9 August 1875.
