I think there was a case when the Colombos killed a nun (Veronica Zuraw) in 1982. Thomas Gioeli was alleged to be involved.
George Aronwald too.
A savage hit and clusterfuck. And people just kept getting killed when they became expendable. The Carinis got popped, then the guys who popped the Carinis got popped. All out of paranoia, and over trying to hit a Fed, which is supposed to be against the rules in the American Mafia. But that's neither here nor there.
