I still say that this is Musitano saying you killed my brother who said he was out, I'll kill your brothers too.
It's hard to argue against this theory at this point. Cece lived next door to his father. The killer could have hit Rocco instead who is supposed to be the capo of the Hamilton Buffalo crew, but he chose Rocco's son for a reason. The same seems to be the case with the Ivarone hit.
