Salvatore Granello was killed in 1970 because introdused verious mobsters to fbi undercover agent and Genovese can't protect him. Another theory was that Granello vowed revenge for his son death.
http://gangstersinc.ning.com/profil...e-of-genovese-crime-family-mobster-salvaWhile in prison in 1968, Granello got news no parent ever wants to hear: his son Michael had been murdered. It couldn’t have been a surprise. 19-year-old Michael was a drug addict who earned his money by playing Russian roulette: He robbed members of the Mafia. Taking after his father’s violent streak, Michael once beat a mobster half to death with a baseball bat during a robbery.
The mob wasn’t having it and shot-gunned young Michael to death while he was sitting in his car.
