Btw dont mean to ruin a good thing here but his fortress was actually located in Bridgeport (Armour Square.)

In 1977, LaPietra celebrated his new position by building a huge, fortress-like house at 30th Street and Princeton Avenue in Cicero. Encircling the home was a 6-foot high brick wall, and, at night, several huge lights covered the whole area. LaPiera’s display of power probably didn’t satisfy everyone in the Outfit, especially his bosses, but he was making a lot of money for them so they kept quiet. Because of that, LaPietra’s influence didn’t just extend around Chinatown, Cicero, and the South Side. He also had many allies and interests from around the Chicago Heights area and some other southern suburbs.

The real location is listed here...
