Oh, I came up with an interesting idea: Neyra is Grim, who tried to recruit Anta. That's why the method of murder is so strange. Plus, the pipe in the picture, plus the spontaneous murder – not with a garrote or a firearm, but with bare hands. And that explains the repeated lack of evidence – because no evidence is provided for self-defense killings. The only questionable point in this case is the 90% and the moving of the body.
What the 90% refers to, I don't know, maybe it's just a figure of speech, and we're looking for the governor of the Kemerovo region...
