DETROIT FREE OF TIE .This Is One City That Has Solved the Problem of the Gangster. 'PURPLE GANG" GONE (By United Press). Detroit. July 19.—Detroit has proved that a metropolis can exist in America without kidnap- ings, payroll holdups, bank robberies and kindred crimes to the organized underworld Since the fall of 1930. when vigorous prosecution broke np the old "Purple gang," and ended a regime of underworld Tlomfna- tion, Wayne county has been free from the kidnaping terror and from major thetts of the marauding gang type. The profits from racketeering which amounted in the wealthy motor city, to $5.000,000 or more a year in .the boom days, have dropped to S500,(M)0 a year, but with the revival of business the racketeers are "stepping up" their demands and striving desperately to horn in on prospective prosperity. Harry 'S. Toy, prosecuting attorney, discovered the beginnings cf the racket boom early in June when the pickup i" the motor industry put cash back into circulation. At his request, a one man grand jury was called into session in the recorder's court and secret investigations were begun . The one man grand jury went into session June 5 before Judge W. McKay Skillman. On June 9, the first warrant resulted and on June 2fi Alexander C. Davis was convicted of extortion. He had attempted lo operate a racket against shoe repair men. The one man grand jury uncovered within a mouth a racket on federal building contracts; a waste paper racket: an attempt to obtain a monopoly on distribution of legal beer; a new cleaning and dyeing extortion scheme; an arson racket and attempts of racketeers to corrupt legislators. But violent crime has dropped amazingly in Detroit, considering that in the boom days when the city was mushrooming into millions it was as ganster ridden as Chicago Though many Chicago and New York gangs won brief footholds in Detroit, it was the home town of the "Purple gang." which made underworld history there. It started as a group of minor racketeers, practicing extortion against cleaners and dyers, providing thugs as drivers for competitive plants and prac- tising in other training fields for gunmen. Before It was broken up it had branched into kidnap- ing, arson, robbery, murder and the inevitable alcohol. Early in 1930 a train of murders started which reached a climax in the assassination six months later of Jerry Buckley, famous radio announcer who had been denouncing gangs. -"Crime crusaders, police officials, and gunmen all fell before the gang- of for sters' guns in thdse months frenzied assassinations. But once the gangsters went too fat and .the public was genuinely aroused. In September, 1930, while the Buckley murder, still was fresh in the public mind, the "Purple gang" assassinated «three members of the rival "Little Navy pangv" and three leading members of the Purple mob were convicted .and given life sentences. This 'vlrtua.'lly eliminated the Purple gang.
