 Aiello 's brother Dominick returned to Chicago in January 1928 to attend to family matters while his brother remained in New Jersey . One day he received a telephone call warning him to leave town , after which the Aiello Brothers Bakery was shot up by gunmen . Aiello briefly allied himself with former Capone employer and friend Frankie Yale , meeting with him regularly in New York City and plotting Capone 's overthrow , until Yale himself was murdered . Aiello was said to have fled to Wisconsin under the protection of the Milwaukee crime family , and also briefly took refuge in Buffalo with his ally there , crime family boss Stefano Magaddino . With Aiello still in hiding , Capone started targeting Aiello 's men and killed several over the next few years , including his brother Dominick . Aiello returned to Chicago in the summer of 1928 and once again approached Moran , whose relationship with Capone had degenerated even further , making him much more receptive to an active alliance with Aiello . They conspired to eliminate Lombardo , a task they assigned to hitmen Frank " Tight Lips " and Peter Gusenberg . Lombardo was shot to death on a busy Chicago street on September 7 , 1928 , and although never arrested , at least one of the Gusenberg brothers is believed to have been among the shooters . After Lombardo 's death , Aiello attempted to elevate his ally Peter Rizzito to the Unione Siciliana position , but Rizzito was killed by shotgun blasts outside his home .
