I think Vinny wanted partnership in the store.When he didn't get it, he came up with this "screwing my wife" bullshit. Only way to retaliate against someone with "Friends".
from what i hear vinny really did think he baker was fucking his wife if my memory is correct it was not sanctioned either. The guys involved were vinny gotti, richie junior, Angelo Ruggiero Jr. The shooter was this guy who turned out to be a fag he flipped later on robert something he got his button then was ordered to do a hit found a funny story on angelo
