Prisoner at
Spandau
a double?
According to Dr. Hugh Thomas' book The Murder of Rudolf Hess (1979), the prisoner tried at
Nuremberg
and incarcerated in
Spandau
as Rudolf Hess was actually a double who was willingly impersonating him. Dr. Thomas examined the prisoner in 1973 whilst serving at BMH Berlin and writes that the man had no scarring that would indicate a bullet wound whatsoever. The real Hess was shot through the left lung, the bullet entering just above the left armpit and exiting between the spine and left shoulder blade during World War I. This finding appeared to be confirmed when the prisoner's body was given two separate autopsies after his death in 1987 neither of which reported finding scarring that would indicate such a wound; however, when Hess's full medical records were released it was revealed that the bullet wound was in a different place than Thomas had claimed, and that scarring from the clean shot was likely to have been minimal.
