This does not square with the accuasations that Moscow is back to its "Soviet tactics". Who in their right mind does not think that the KGB has very effective posions that leave little or no trace. The accusations that he was posioned by endotoxin made much more sense. Endotoxin is made by the bacteria in human intestine and the proper preparation of endotoxin would be hard to distinguish from what is already in your body. Some reports I have read from American sources said he was posioned in September, yet where was all the media attention then?
