I've seen D'Amico's name mentioned a lot over the years. Robert Cooley mentioned him in a video. Cooley implied he was pretty powerful in The Outfit. I just looked at Wikipedia to get some basic info. So what was his status? Sounded like Cooley was saying he controlled quite a few gambling operations.

Oh yeah, Cooley also said he (Cooley) got into some gambling problems and went to see J. DiFronzo and his debt was forgiven. I believe he later gave testimony about JD

Good ole boys!
