My understanding is that Phillip Testa was murdered by Frank Narducci, Pete Casella, and Rocco Marinucci, who were of the opinion that Casella, and not Testa, should have been named boss.
Narducci was also irritated he was not named consigliere to Testa who instead gave it to his friend Nicky Scarfo. Casella never had a prayer to be boss, he was in poor health by 1980 and not popular with New York, he died only a few years after the Testa hit. Narducci and Marinucci were both murdered by Salvie Testa and Anthony Pungitore Jr. in late 1981.
