Peter Gusenberg

After graduating from petty crime into more serious offenses, the Gusenberg brothers teamed up with Dean 'Dion' O'Banion, Earl 'Hymie' Weiss, Vincent 'The Schemer' Drucci, George 'Bugs' Moran and other members of the North Side Gang.

He later married a German-Irish woman Myrtle Coppleman Gorman and did not let her know about his criminal activities, keeping her under the ruse that he worked as a travelling salesman.

He also helped carry out the murders on Antonio Lombardo and Pasquale Lolorado with his younger brother Frank Gusenberg and Albert Kachellek, a fellow cellmate at Joliet.

On September 20, 1926, Peter Gusenberg participated in the infamous drive-by shooting on the Hawthorne Hotel, Capone's Cicero, Illinois headquarters.

According to many accounts, the second to last car stopped in front of the hotel restaurant when Peter Gusenberg emerged, clad in a khaki Army shirt and brown overalls, and carrying a Thompson submachine gun.

Kneeling in front of the doorway, Gusenberg emptied the entire 100-round capacity drum into the restaurant, and then casually strolled back to his car, which then sped off.

Aiello and the Gusenberg brothers first killed Antonio Lombardo and then Pasqualino "Patsy" Lolordo, two successive presidents of the Unione Siciliane and both Capone allies.

Also there were Frank Gusenberg, Albert Weinshank, Adam Heyer, James Clark, John May, and Dr. Reinhardt Schwimmer (a friend of a gang member).

The general accepted story is that the North Siders were waiting for a shipment of hijacked Log Cabin brand whiskey from Detroit (a ploy devised by Capone).
