Great post, Sinatra. I'm of the belief that he was most likely involved as well. I just read Leonetti's book not too long ago, and I remember a part in the book where he talks about being in New York with Scarfo, hanging out in a bar playing cards with Benny Egg's guys while his uncle was meeting with the Chin and Bobby Manna (this was at the same time that Caponigro was summoned I believe). I can't remember exactly how it went, but something along the lines that Stanfa was also seen in a local bar and one of the Genovese guys noticed him and thought he was somebody else. Leonetti then says that he believes if the Genovese guys really knew that it was Stanfa, that he would have been killed too.

I think Stanfa actually got really lucky being indicted for perjury and eventually being captured and spending those years in prison. Had none of that happened and he remains on the streets in South Philly, I don't think there is any question that Scarfo would have had him killed.
