The indictment (PDF), unsealed on Monday, includes an extensive look into Paul Manafort’s byzantine financial dealings. In particular, it details how he used a company called Lucicle Consultants Limited to wire millions of dollars into the United States.

The Cyprus-based Lucicle Consultants Limited, in turn, reportedly received millions of dollars from a businessman and Ukrainian parliamentarian named Ivan Fursin, who is closely linked to one of Russia’s most notorious criminals: Semion Mogilevich.

Mogilevich is frequently described as “the most dangerous mobster in the world.” Currently believed to be safe in Moscow, he is, according to the FBI, responsible for weapons trafficking, contract killings, and international prostitution. In 2009, he made the bureau’s Ten Most Wanted Fugitives list.
