Why did Bonanno kill his first two Consiglieres?
Francisco Italiano was in opposition to Joe for the Boss seat in 1931. He didn't have enough standing within the Family to challenge him but was made Consigliere. I don't know the specifics (maybe GV has insight) but I imagine they couldn't work together. Italiano was probably subversive.
Fillippo Rappa took his spoke but was replaced by John Tartamella. He was killed in 1944 for unknown reasons
