Guy Lombardo
On November 5, 1977, Lombardo suffered a fatal heart attack. Another source says he died "of a lung ailment." His wife was at his bedside when he died in Houston Methodist Hospital.
Joe Aiello
In November 1927 Aiello organized machine-gun ambushes across from Lombardo's home and a cigar store frequented by Capone, but those plans were foiled after an anonymous tip led police to raid several addresses and arrest Milwaukee gunman Angelo La Mantio and four other Aiello gunmen. After the police discovered receipts for the apartments in La Mantio's pockets, he confessed that Aiello had hired him to kill Capone and Lombardo, leading the police to arrest Aiello himself and bring him to the South Clark Street police station. Upon learning of the arrest, Capone dispatched nearly two dozen gunmen to stand guard outside the station and await Aiello's release. The men made no attempt to publicly conceal their purpose there, and reporters and photographers rushed to the scene to observe Aiello's expected murder. Capone gunmen Frank Perry, Sam Marcus and Louis "Little New York" Campagna were arrested as they tried to enter the front of the station and placed in the cell next to Aiello, who Campagna told, "You're dead, friend, dead. You won't get up to the end of the street still walking". Aiello pleaded for mercy and promised to sell his possessions and leave Chicago with his family if they let him go, but Campagna refused the request. When released, Aiello was given a police escort out of the station to safety. He later failed to make a court appearance after his attorney claimed he suffered a nervous breakdown. Aiello disappeared with some of family members to Trenton, NJ, where he continued his campaign against Capone and Lombardo.
