Smith's account is thought by historians to be dramatic licence on his part, and the kidney could have been a medical student's prank. Dr Saunders, who attended the post-mortem, told the press, "the right kidney of the woman Eddowes was perfectly normal in its structure and healthy ... my opinion is that it was a student's antic." Chief Inspector Donald Swanson, who co-ordinated the inquiry, wrote: "similar kidneys might and could be obtained from any dead person upon whom a post mortem had been made for any cause, by students or dissecting room porter."
