After a 1955 car bombing in which the girlfriend of Arthur "Little Brother" Drake was killed, police conducted a mass roundup of 28 numbers operators and runners on the east side, including Drake, Geech Bell, Don King, Edward Keeling, Dan Boone, Thomas Turk, and others. The following year Jewish gangster Shon Birns tried to keep the peace by setting up a 5-member syndicate of the leading black operators in Cleveland including Don King, Virgil Ogletree, Boone and Keeling to control the game, insure payouts when "hot" numbers which had been overbet hit for large scores, and limit the payoff odds to 500 to 1; Birns also attempted to introduce a new method of determining the winning number. The game was wildly popular; in the 1950s one Cleveland numbers house was said to clear $20,000 a day.
