 In November 1925 Lombardo was named head of the Unione Siciliana , a Sicilian @-@ American benevolent society that had been corrupted by gangsters . An infuriated Aiello , who had wanted the position himself , believed Capone was responsible for Lombardo 's ascension and he resented the non @-@ Sicilian 's attempts to manipulate affairs within the Unione . Aiello severed all personal and business ties with Lombardo and entered into a feud with him and Capone , essentially ending a Chicago gang peace treaty that had had been in force since the 1926 murder of Capone rival Hymie Weiss . Aiello allied himself with several other Capone enemies , including Dean O 'Banion , and the trio of Billy Skidmore , Barney <unk> and Jack <unk> , who ran vice and gambling houses together , although they became less receptive to Aiello after Capone personally approached and threatened Skidmore . While newspapers falsely reported that Aiello had also entered into an active alliance with George " Bugs " Moran and his North Side Gang at this time , Moran in fact pledged no specific support to Aiello until later , and instead privately supported Aiello from the sidelines without actively participating .
