Could the Shroud of Turin be an effect of post-mortem changes?

! A 76-year old man was found lying on his carpet after being dead for several weeks. When his decomposing body was removed, putrefaction stains had left an image of his body on the carpet. Although there is no suggestion that the Shroud received its image in this way, this paper adds to the very small number of cases in which the image of a dead person has been left naturally on the surface it was lying on. Another noted case is that of the 44-year old man who left an image on his plastic mattress-cover (The Jospice Mattress case, see Louis de Figueiredo’s paper at http://thegroundoffaith.net/issues/2009-08/Jospice.pdf). Both cases are of peripheral interest rather than direct relevance, but provide some interesting comparisons and points for discussion.
