5. Semion Yudkovich Mogilevich
From Italy, we shift a little bit to Russia. Semion Yudkovich Mogilevich is not just an ordinary mafia. European and United States federal law enforcement agencies believe that he is the boss of bosses of most Russian Mafia syndicates in the whole world. In fact, FBI refers him as the most dangerous mobster in the world.
He is wanted for weapons trafficking, contract murders, extortion, drug trafficking, and prostitution on international scale. He was named to the FBI’s top ten fugitive list in 2009 but removed six years later. FBI stated that one of the reasons is the fact that he is living in a country which the US does not maintain an extradition treaty with.
Unlike most fugitives, Mogilevich is living freely in Moscow, Russia. He is known as Don Semyon or The Brainy Don. And it is believed that he controls RosUkrEnergo.
If you ask any Russians, most of them will say they know about Mogilevich. But they will choose not to speak of him.
