I am very interested to see how this ties in with the decision to retry Ligambi. We all know that being on trial doesnt stop someone from ordering a hit. And (although I am not certain) I dont know that Ligambi himself had to order it. Even if Merlino or Mazzone ordered it, if it was done on behalf of Ligambi and/or "the family", there is a possibilty that the murder can be added onto charges of Ligambi. (Im not absolutely certain, and it would be risky for feds to do this because it could water down the other charges in jury's mind).
The Feds decision to retry Ligambi (in APRIL!) is interesting. And you can be sure that Nicodemo is feeling pressure from all sides (The State, The Feds, and The Family). Whether he was the trigger man, was there, knew about it, or had no clue, is irrelevant. I wouldnt wish his situation on my worst enemy.
