In early 1933, Myles O'Donnell was shot by a bartender during an altercation. Although O'Donnell fatally shot the bartender, he sustained a gunshot wound to the lung and subsequently contracted
pneumonia. He died on March 10, 1933. Following his brother's death, William "Klondike" O'Donnell assumed control of the West Side rackets but was unable to replicate their former profitability. With Prohibition repealed and the bootlegging operation dissolved, Klondike attempted to sustain his income through a fleet of trucks, which he supplied to Chicago gangster Jack "Three Fingered" White. White operated a labor union racket known as TNT, which coerced members into making payments and dues. The operation eventually attracted federal attention and was shut down, leaving Klondike without a source of income.
