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.
"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming
Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
