“An ally of Russian President Vladimir Putin “
The majority in Russia are getting financially destroyed because of Putin’s insane misadventure. Expect more “persuasion” to end the misadventure.
Another theory would be actual murder-suicides by two men facing certain consequences or fearing that something awful lies ahead (from inside knowledge).
Reminds one of the Toronto deaths a couple of years ago, of a prominent couple with government connections, police investigations ongoing, one story being possible murder-suicide, another being silencing of potential harmful information coming out from them or because of charges pending against them, or mob activity of some kind.
The fact that these two similar events involving related powerful men came close together in time indicates high probability that the same cause and effect prevails in both cases. Would not discount the murder-suicide angle after they perhaps conferred about shared suspicions of pending doom. Question is, doom for them, or doom for everyone?
