 On March 18, 1964, John Montana died shortly after being admitted to the Buffalo General Hospital because of a heart attack.He was survived by two brothers, Peter and Angelo, and his nephew Charles who was solidly entrenched in the Mafia's hierarchy; Charles and his wife Josephine Magaddino lived in a lavish house on Mafia Row out in Lewiston, where Stefano Magaddino, his sons-in-law and daughters each had houses.While Rose Montana and her attorney John J. Naples had copies of the will, Buffalo will never know the extent to which John Montana had his hand in the affairs of the Mafia – in the affairs of the community – in the affairs of business – in the affairs of the government.
