DiFronzo may have been the boss but Monteleone was the guy running things on the streets and doing the dirty work. Pretty much everyone else was dead or in prison.

Monteleone did some time for contempt by refusing to testify about some car bombs in Milwaukee. He ended up serving four years (1986-1990) which was pretty steep for contempt. He probably died at the "right" time because if he would have lasted another couple of years he would have been caught up in all the Family Secrets stuff.
