 Upon finding the wrecked car, police traced the vehicle to Bergl's shop and arrested Gus Winkler, a member of the Chicago Outfit and Bergl's silent partner, naming the Chicago gangster as a member of a national armed robbery syndicate which supposedly included Depression-era bandits George "Machine Gun" Kelly and Vernon Miller.Winkler was killed in a gangland slaying by unidentified gunmen on October 9, who reportedly suspected he would turn state's evidence in exchange for a reduction of the long prison sentence he was facing.Although Bergl was allowed to live, the exposure to law enforcement officials ended his usefulness to the crime syndicate, as criminals turned instead to competitor Clarence Lieder.
