Russia states they have confirmed Prigozhin’s death, what do you believe happened?

I think he got scared and figured making his death seem as real as possible was a better alternative than not. The best way to run from your enemy is to make him think he already killed you, because then they stop looking. He wasn't a stupid man and was known to be so paranoid he had all those body doubles and stuff like you said. It wouldn't surprise me if he got unalived but IMO he wanted out from under Putins gaze.
