 Aiello was also believed to have masterminded the murder of Pasqualino " Patsy " Lolordo , Lombardo 's successor as head of the Unione , who was killed in his home on January 8 , 1929 . Police alleged that Aiello suggested a truce with Lolordo , and when Lolordo invited Aiello into his home for a toast of friendship , Aiello and two others shot him to death . When police later questioned Lolordo 's widow , she screamed when she was shown a photo of Aiello , but refused to explain why she was afraid and would not answer questions about him . Capone focused his retaliation against Moran by organizing the St. Valentine 's Day Massacre , a hit that wiped out the Gusenberg brothers , decimated Moran 's forces and resulted in the loss of a significant amount of Aiello 's support . Shortly afterward Aiello persuaded Capone killers Albert Anselmi and John Scalise to betray their employer and convinced Joseph " Hop Toad " Giunta , the new head of the Unione Siciliana , to support Aiello in eliminating Capone and taking control of the North Side of Chicago following the departure of Bugs Moran . However , Capone learned of Aiello 's plot in April 1929 and killed all three men .
