After Dion O'Banion double-crossed him at Sieben Brewery, Johnny Torrio's south side organization came into constant conflict with the North side gang. With encouragement from the Genna brothers, Torrio had assented to O'Banion's murder.
In retaliation, O'Banion's followers targeted Torrio. After the bust at Sieben, Torrio had turned over his major operations to Al Capone, making him think he was safe from rival gangsters. However, Hymie Weiss and Bugs Moran, two of O'Banion's lieutenants, were motivated by revenge, not business matters, and about 4:30 p.m. on a cold January morning in 1925, they ambushed Torrio in front of his home, pictured here, at 7011 S. Clyde Ave.
Torrio and his ever-loyal wife, Ann, had spent the day shopping in the Loop, and had just returned to their South Shore home. Accompanied only by their driver, they walked up to the front door, with Torrio carrying a load of packages, unaware of the blue Cadillac that had arrived moments after them. Weiss and Moran jumped out and unloaded a hail of bullets, first at the Torrios' car (wounding the driver, who was still inside), then at Johnny Torrio himself. One bullet in the arm, another in the groin, both at point blank range. Finally, Bugs Moran put his pistol to Torrio's head for the coup de grace. Click. No bullets left.
Torrio survived the hit, though barely. After four weeks in the hospital, protected by Al Capone personally at his side day and night, Torrio served his nine-month sentence for the Sieben bust at Lake County Jail, then departed immediately for Italy, where he lived for several years before returning to New York. He never set foot in Chicago again, and Al Capone took over the leadership of his organization.
