First of all there is no "the RUSSIAN MAFIA". There are many groups, some ethnic Chechen, others former KGB or other ex and current military and security personel. They surely have Jewish members but to say that they are 95% Jewish is a stretch. There may be more "Jewish Russian Mafia" in the US then in Russia because of Visa restrictions, but not 95%.
As to the victims association with the Mafia, he probably had none. He was meeting new business associates just before he was killed. My guess is that it was simple extortion. They told him to pay them $100,000 or whatever, or they would kill him. He tried to but couldn't come up with the money fast enough so they killed him.
Come on! The term was used -- in Moscow, by Russians -- as long ago as the early 1980s. (Was there. Heard it.)
Objection, your honor; calls for speculation.
'her father was meeting new business associates who wanted to build 20 homes in Malibu. The next day he repeatedly tried to clean out his bank account.
"He called the bank four times saying that he needs the money out and that he was in danger, but there was a slip-up at the bank," his daughter said.'

Sorry, sir. You can't take it with you.
I frequently eat at restaurants in other immigrant/ethnic neighborhoods, and find that they are consistently kind (except of course for the ubiquitous "punk kid" common to all peoples).
Koreans, Vietnamese, Jamaicans, Puerto rican, Mexicans, non-russian Jews, Greeks, Amish, Germans, even the English are welcoming -- but not the russian jews.
Why are the russian jews such pissers?
