Man Confesses to Dissolving Body in Acid, Certain No Court Can Convict Without a Body: The Murder of Olive Durand-DeaconFebruary 1949, London. A sixty-nine-year-old widow vanishes after leaving her hotel with a businessman offering to help develop her business idea. What police discovered in the warehouse would expose a calculated system of murder-one that had worked flawlessly five times before. A pathologist's examination of two hundred kilos of greasy soil revealed what sulfuric acid could not destroy, unraveling a killer's fatal miscalculation.In this episode, we explore how John George Haigh built a method that eliminated bodies but left behind systematic evidence: forged documents, jewelry sales witnessed by dealers, bloodstains on warehouse walls, and the meticulous planning of a con artist turned serial killer. How did a pathologist named Keith Simpson identify a victim from fragments the acid was supposed to obliterate, and why did Haigh's confidence in the absence of a corpse become his undoing?Victim: Olive Durand-DeaconDate: February 18, 1949Location: South Kensington, London / Crawley, East Sussex, EnglandStatus: Solved- A killer voluntarily accompanied the victim's friend to report her disappearance to Scotland Yard the very next day- Haigh confessed without pressure, believing sulfuric acid had made conviction impossible without a body- Pathologist Keith Simpson discovered a gallstone the size of a cherry, preserved by protective fat tissue the acid could not penetrate- Olive's dental prosthesis and bone fragments allowed definitive identification, collapsing Haigh's entire defense strategyOlive Durand-Deacon, John George Haigh, London serial killer, sulfuric acid murder, 1949, forensic science, criminal minds, pathology, unsolved vanished, true crime EnglishTo listen to this podcast ad-free and access premium episodes, try our subscription with a 14-day free trial at obomedia.com.© 2026 OBOMEDIA.
