I am surprised and very impressed that it was possible to quantify CO-Hb in a body that had been underwater for so long - I trust they are really confident. I would have expected all the post mortem changes of pH and osmolarity to mess-up the protein 3d structure and destroy the binding sites. I guess they measure the ratio of COHb : O2Hb, but they must break down at a differential rate depending on all sorts of factors. Of course it must be very cold at depth in the English Channel which will help. I am not doubting the result, but I must say a 2nd body with the same evidence would have greatly increased the confidence this this wasn't some kind of artifact.
