Big surprise, huh? He's the guy who made a move on Moscow lately, then changed his mind. A deal was made for him to back off and move to Belarus. Which he apparently didn't do. There is a history of people who defy Vladimir Putin coming to grief. Often by poison of some kind. In this case, the wing of his personal airplane mysteriously fell off in flight. No reason to mourn, Prigozhin was a very evil person.
