I honestly have no idea. Yet one begins to paint the picture by contemplating whom would have great benefit and great loss by his death. One may also contemplate what entity would have the power perhaps to think they are above "the law" to do carry this out so there are no significant unattended consequences. Then one will continue to think this way not unlike a seasoned chess player and perhaps reach a conclusion. Now if I am not mistaken, and indeed I have been before, Stalin was like this. Thus if this was part of a dozier for him it may indeed fit. Are there any associations with Stalin and this man you mentioned? What was his name?
