Why would Putin need that? The plane was literally landing in russia. Putin could just have that person be arrested then or just disappear ("must have been russian maffia"). Not like russians try to hide murdering people.
Prigozhin was a very different case, not that many people have their own paramilitary organization to defend them. Only other such person I can think of is someone like Kadyrov.
You mean the guy that had his own army, and had support by a large chunk of russia? The guy Putin had publicly said would face no criminal consequences?
