I am much less impressed of stories where someone who had a lot of money killed or harmed rather than of stories where someone "socially unprotected" killed or harmed.
Reason: That organized crime you all referring to was on the rage in early- and mid-90s. And they practically killed themself out. If you go to some cemeteries you would find a lot of expensive monuments to mobsters aged 30-40 yrs. There are much, much less organized crime now (you don't hear about it even if you know where to listen), partly because some of it legalized, partly because most of it killed itself. They just could not help it.
Levels of high-profile corruption vary in Russia, but everyone would agree that real estate is the apex of it. If you got there and got killed, it's like if you gambled with borrowed money and lost it all and then got your legs broken. Happens everywhere if one is stupid enough. (rem took the debt-legs breaking concept from US popular culture).
So while for someone with US/European background this story reads like the crime of the century, Russians would instead focus more on issues which can hurt ordinary people more likely (hint: list of issies which can realistically hurt you in Russia if you're an ordinary person does not include mafia, not at all).
