I'm reading a Dutch book now which is not very actual (1964) but now I read something I think it's completely wrong:

"...they were helped by expert named Vincente Collura. He was from the US. He was one of the close employees of Mafia-gangsters like Joe Prefaci and Frank Copollo."

The question here is: Frank Copollo, shouldn't that be Frank Costello? Or does he really excist? Tell me about it. (Prefaci is Profaci ofcourse)

And if someone can tell me about Collura. Please say it.
