Actually there's not a lot of info available on the Lopresti sr murder. He was basically the Rizzuto emissary to New York before George from Canada was, and there's theories of a falling out of sorts. He supposedly did something that someone didn't like.

Great posts, eurodave; your bringing a lot to the GBB table. The Canadian situation is definitely an interesting one. The point you made about the distinction between Italian-Canadian mobsters as opposed to Italian mobsters in Canada is very apt.
