As reported exclusively by russian sources at the moment, he lost consciousness after a walking hour and prison medics were unsuccessful in reanimating him, as per sources in УФСИН (government body regulating prisons and punishment). He was 47 years old at that time. The last time he was heard of he was moved from Moscow-based prison into the IK-3 named Polar Wolf, a penal colony located in a permafrost region near the town of Harp, where he found his end.
No other sources commented on that by now. At that time, there's no independent proof of that or other explanations but the one given by prison authorities.
A fitting reminder is that presidential elections are to be held in 15-17 of March, meaning it happened exactly one month prior to them.
Russia desperately needs another revolution.
I don't know how you are proficient in russian history, but we have a thing called гонка на лафетах. At some point soviet administration grew that old they all died off in a decade, without coming up with a next gen of rulers. I feel like in a coming decade there would be a lot of funerals and the new chaotic 90s for Russia, Iran, that would be very painful for these nations, but it'd be another chance to start it right, at least as a lib democracy. People say I'm too dumb and optimistic, but there's still no successor to Putin and he's born in 1952, and the clocks are ticking. He and his friends are just to afraid to lose their place so they don't bother with that, meaning it would be a complete hell when they'd die one by one.
that's interesting to hear from your perspective, thanks for the insight. When I read these headlines I always wonder what real Russians think
