allegedly masterminded by a young wannabe, Marat Krivoi, who ran a tough crew of thugs with an eye toward impressing his father-in-law, Russian mob don Boris Nayfeld. ==
"Russian" mob again?:) They speak russian language probably with jewish accent. That is all which connects them to Russians.
"Krivoi", "Ivanitskii", "Nayfeld" sounds like all from Odessa, Ukraine.
What's a Jewish accent in Russian?
(serious question)
Probably? What's this based on? I don't know any Jews with the first name "Pyotr". Krivoi and Ivanitski can go either way. As for Nayfield, his daughter may have married a russian man. This is all wishful thinking on your part. I've met a bunch of the stick up kids in the early to mid 1990's (some from high profile cases you may have heard) and I can tel you that a majority of them was not Jewish. In fact some went back to Russia to escape their warrants.
