I already stated above the reason. YES, Nicoletti was killed on orders of Auippa/Cerone because he was very loyal to Mooney and was a very dangerous man. I have no idea who was the shooter, but I can tell you it was more than one guy involved.
Yes the police also theorized that there was more than one person in the car with Nicoletti.Thanx again
