Chicago, USA Adolphe Luetgert killed his wife, Louisa, and then burned it in potash to destroy the evidence. This potash was then delivered to his sausage factory and put into a vat.

The murder was quickly discovered after Louisa's family called the police after they hadn't seen her for a few days. They called the police.

The trail led quickly to the sausage factory and when investigators looked in the vat they discovered her engraved rings and minute bone fragments.

Whilst there were problems at trial on proving that these small fragments of bone were, indeed, human, there was sufficient circumstantial evidence to convict him.
