Joel Glickman was never really a Mob Associate in Chicago, at least in regards to the Associate/Soldier model in Chicago. He was an independent bookmaker in the North and Northwest suburbs with a higher end clientele that paid the mob street tax for the privilege to operate.
In the 1970s, he paid the tax to the Cicero crew, but unknown as to what branch (Ferriola, Infelise, Carlisi, who knows). Sometime in the 1980s he started to pay the mob street tax to 26th Street (the Calabrese crew).
He did end up testifying against Frank Calabrese Sr. after spending a week in jail. He did not testify as to any evidence against the other defendants because he the only defendant he had met was Calabrese.
He is now in his late 70s and has not run book for years, since at least the mid to late 1990s, well before Family Secrets.
