I count eleven Russian oil company executives murdered or dying under suspicious circumstances in the last twelve months. One of the hallmarks of Russian Mafia/KGB ops is they are not shy about murdering relatives - even children. Imagine if U.S. oil company executives and their family members were getting bumped-off at this rate. It would be a national headline. 

In Russia it's apparently just business-as-usual. 

One of the reasons they are so despised/feared by Russians.
