100 Murder Cases

Acid bath murderer John George Haigh.

John George Haigh was a British serial killer active in the late 40's. He used to dispose of his victims' bodies by burning them in sulphuric acid, according to Forensic magazine. Haigh was convinced he was getting away with murder, literally, because he mistakenly thought that without a body there was no crime. His arrogance is what ultimately got him caught when he led police to the remains of his sixth and final victim, 69-year-old Olive Durand-Deacon. While on trial, Haigh pleaded insanity and insisted to the court that he drank the blood of his victims. He was found guilty in 1949 and hanged a few months later.
