When Nathan Leopold and Richard Loeb, two well-educated college students from a wealthy suburb of Chicago, confessed to the brutal murder of 14-year-old Bobby Franks, the story made headlines across the country. The unlikely killers not only admitted their guilt, but also bragged that they had committed the crime simply for the thrill of it. As the sensational case unfolded during the summer of 1924, with famed defense attorney Clarence Darrow and Cook County Prosecutor Robert Crowe debating the death penalty and scores of commentators weighing in from the sidelines, the question of motive would be turned over and over again. What first seemed like a simple matter of evil gradually would give way to a complex assessment of the murderers’ minds and a searing indictment of the forces that had shaped them, and set off a national debate about morality and capital punishment.
