John Haigh

John George Haigh, commonly known as the Acid Bath Murderer, was an English serial killer convicted for the murders of six people, although he claimed to have killed nine. Haigh battered to death or shot his victims and disposed of their bodies using sulphuric acid before forging their signatures so he could sell their possessions and collect large sums of money. His actions were the subject of the television film A Is for Acid.
