The Death of Russian Businessmen

In the space of a year more than a dozen rich Russian businessmen have died in either brutal or mysterious circumstances. Some fell out of windows, some had heart attacks and a few of them even killed their whole families before committing suicide. The official line from the Russian authorities is that most of these deaths were accidents or violent consequences of mental illness. But considering the majority of these dead rich Russians are either outright oligarchs or have other links to the Kremlin, it's possible that something much darker is taking place.
