Unveiling the Dark Tale of John Haigh: The Acid Bath Murderer True Crime


In the annals of crime history, few names evoke as much dread as that of John Haigh, infamously known as the Acid Bath Murderer. This English serial killer left a trail of horror in the mid-20th century, convicted of brutally ending the lives of at least six individuals. Let’s delve into the twisted narrative of Haigh’s life and the heinous acts that led to his execution.

Early Life

John Haigh was born in Stamford, Lincolnshire, and raised in the conservative Plymouth Brethren community. Despite a seemingly ordinary upbringing, he harbored dark visions from childhood, coupled with a passion for classical music. Haigh’s path took a sinister turn when he forged car documents after being dismissed from his apprenticeship.

Marriage and Imprisonment

In 1934, Haigh married Beatrice ‘Betty’ Hamer, but the marriage quickly unraveled. His fraudulent activities landed him in jail, and Betty, left alone, gave their child up for adoption. Haigh’s life took a downward spiral as he engaged in a series of criminal pursuits, eventually leading to imprisonment.

“Acid Bath” Murders

Released from prison in 1943, Haigh masqueraded as an accountant. His encounter with former employer William McSwan sparked a murderous spree. In a macabre twist, Haigh disposed of victims in drums of sulphuric acid after bludgeoning or shooting them. His motive? Profit. The Acid Bath Murderer’s gruesome acts continued until his arrest in 1949.

Last Victim and Arrest

Haigh’s final victim was Olive Durand-Deacon, a wealthy widow. After luring her to a workshop under the guise of discussing an invention, he shot her, dissolved her body, and continued his grisly charade. Detectives, uncovering Haigh’s record of fraud and theft, arrested him, exposing the horrifying truth.

Trial and Execution

Haigh’s trial unfolded at Lewes assizes, where he pleaded insanity, claiming to have drunk the blood of his victims. The prosecution led by Sir Hartley Shawcross dismissed his defense, emphasizing malice aforethought. The jury swiftly found Haigh guilty, and on August 10, 1949, he faced the hangman’s noose.
