   He's another possibility, say he was abducted by aliens and taken to the   
   mothership orbiting Alpha Centauri...   
      
   Its about as likely as any of your scenario's.   
      
   And Banana talks of "whoopsydaisyists".   
      
   This is just a guess, call it a wild stab in the dark, but you didn't do   
   O-Level Biology, did you?

   Tests are usually taken from 4 places, a vein, an artery, and any tissue   
   around an organ (except the liver), and the space around the lungs.  In post   
   mortems, the tissue around the eyes is often used to take the third blood   
   sample.  The readings SHOULD all be different, the highest one for CO being   
   from the tissue around the lungs.

   It would show that you had mixed two peoples blood, as there would be two   
   sets of DNA.   
      
   Do you ever watch or listen to the news?  Unless you actually HAVE been on   
   Alpha Centauri for the last ten years, you can't have failed to notice that   
   there has been quite a bit of fuss over "Human Cloning", and DNA research   
   into disease treatment, and even a couple having a DNA altered child to   
   treat their ill first child.  Does "Dolly the Sheep" not ring a bell?   
      
   You have probably listened to all the above, and more, but still think that   
   DNA can be altered by mixing two peoples blood in a test tube. Damn, and all   
   this time all these incredibly clever-clogs scientists have been wasting   
   billions of pounds of tax payers money to push the boundaries of human   
   knowledge and achievement, when all they had to do was shake a few test   
   tubes full of blood.   
      
   > I wonder, also, whether it's possible to contaminate a person's

   You seem to totally misunderstand the whole concept of DNA, or the   
   biological actions required for CO to enter the bloodstream.  It's not just   
   a matter of getting a test-tube full of CO and mixing it with some blood,   
   like you would if you were making a cocktail, or baking a cake, it's a   
   little bit more complicated than that.   
      
   The CO has to replace Oxygen at a molecular level. It's not just a matter of   
   getting some alcohol, and a bit of CO, and shaking the testube.   
      
   When the figures are given for CO in the bloodstream, it doesn't mean that a   
   figure of , say,  21%, means that if you got a pint of this blood it would   
   contain 21% CO.  What it means is that 21% of the oxygen carrying   
   haemoglobin has been replaced by CO carrying haemoglobin   
   (carboxyhaemoglobin). The efficiency of your blood to supply oxygen to the   
   body has been reduced by 21%.   
      
   A person suffering from a carboxyhaemoglobin rate of 21% would feel any,   
   some, all, or none of the following conditions :- dizziness, nausea,   
   vomiting,  loss of judgement.   
      
   Unconsciousness occurs after 50-60%, and death usually above 60%.   
      
   The affects obviously are conditional on several factors, such as   
   body-weight, Sex, general fitness levels, whether you are a smoker, etc,   
   etc.

   In any blood test, the first thing that is tested is the DNA.  It would be   
   the simplest thing in the world to tell that it was not his blood. The whole   
   " switched blood samples" is a complete red-herring, and a non-starter.  Of   
   course, if it was an assassination, then MI5, MI6, CIA, FBI, Mossad, The   
   Masons, Aliens from Alpha Centauri (delete as appropriate dependent upon   
   your favourite theory) managed, with incredible split second timing, to get   
   them to switch to a pre-doctored car, go through a tunnel they didn't want   
   to go through, have people waiting in the tunnel, have people planted in the   
   ambulance, the hospital, and in the pathology lab (not to mention the French   
   Police and Fire Brigade and the French Government), and also managed to keep   
   all the hundreds of "ordinary " workers and members of the public in all of   
   these places "on side", and yet succumbed to the most elementary schoolboy   
   howler of a mistake by "switching the blood samples".  If you think this is   
   true, then I believe you've been watching too many episodes of Scooby-Doo   
   (damn, if it wasn't for those pesky kids on the internet, we would have got   
   away with it).  I bet you watch "Columbo" too.   
      
   In all this fuss about the CO in his blood, have any results been published   
   of any other blood tests?   A CBC must have been taken (Complete Blood   
   Count) to determine if HP had been poisoned, and would have discovered the   
   high alcohol levels. This would give a much fuller picture of the condition   
   of his blood at, or just before, his death.  I would find it highly   
   improbable that this type of test was NOT carried out, because it is used by   
   Pathologists as one of the tests to determine if the body had been bleeding   
   prior to death (increase in white blood cells) or had been exposed to CO   
   (increase in Red blood  cells). The full results of this test will give a   
   much fuller picture than the "21%" CO figure, which, without the full   
   result, is pretty meaningless.   
      
   Of course, the 21% CO figure is also dependent upon his RBC (red blood   
   count), as his level of oxygen carrying red blood cells would have an affect   
   upon when he might begin to feel the symptoms of CO poisoning. If he had a   
   high level of red blood cells to start with, then it would take a higher CO   
   percentage for the symptoms to "kick in".
