Many of the show's stories come straight from the news. For example, recently an analyst in Maryland chewed through the locations a serial bank
robber had hit in order to predict his future targets; cops arrested the crook while he was casing his next job. On the show, Charlie helps the FBI track a thief in the same way, with the requisite dramatic twist (someone gets shot). And in the pilot episode, Charlie traces the home of a serial rapist based on the locations of his attacks. Kim Rossmo, a real-life mathematician-detective, developed this very equation, which solved a Louisiana rape case in 1998. Rossmo watched that episode, which includes a scene that compares scattered crimes with droplets sprayed by a lawn sprinkler--a metaphor he used in our April 2003 profile of him. "I can say with 99 percent confidence," he notes, "that the Popular
Science article is where the TV writer got the information."
