State investigators declared a month or two months ago, that Vitebsk explosions were just vandalism. And they declared that they caught two or three “vandals” responsed for those explosions in Autumn.
No new open information arrived till now. I can’t remember neither news about investigation, no information about official charges to “vandals”.
For me, it seems that vandalism is quite possible hypothesis, much possible then two hypothesis you’ve mentioned.
But who is responsible personally—it’s a question. I think it’s hardly Dorofeev, and there’s a big possibility that mentioned “vandals” are innocent too.
I’ll keep monitoring of open information about investigation of Vitebsk explosions .
