it was tony who was responsible, joey lombardo was the one who sent spilotro to las vegas, he started his own family there, which he didn't have permission to do, according to culotta's book, and others, his head really got big, and i think after reading about him and lefty rosenthal, they were in way over their heads, lefty rosenthal even had his own T.V. show, representing the outfit with a t,v, show?? later it was brought to light that lefty was giving information to the FBI, but it was spilotro that was bringing down the heat, and aiuppa had to put a stop to him, he just outlived his usefullness.
