Catherine Eddowes
Part of a left human kidney, accompanied by a letter addressed From Hell and postmarked 15 October, was later sent to the chairman of the Whitechapel Vigilance Committee, George Lusk. The author of this letter claimed the section of kidney was from Eddowes, whose left kidney had been removed, and that he had fried and eaten the other half. Most experts, however, do not believe this kidney actually originated from Eddowes's body.
