Crime: No. 1,000

Robert Thomas Hannah, 31, was a petty hoodlum and narcotics peddler who helped Illinois authorities trap a big-time dope pusher. Last week, his frozen body, containing six bullets, was found in the snow at the edge of a forest preserve outside Chicago. He thereby achieved a dubious fame: his murder marked the 1,000th gangster killing since the Chicago Crime Commission began keeping count in 1919. Only 13 have ended in convictions.
