O'Banion is thought by some to briefly have been part of Johnny Torrio's gang (later Capone's gang), but it is more likely that the men merely had a working relationship.
O'Banion was a florist by trade. He was shot dead in his florist shop in 1924 supposedly by gangsters (perhaps one of Frankie Uale's jobs) who were picking up a floral arrangement for Mike Merlo's funeral.
