MINNEAPOLIS -- Ryan Hughes, a young, spiky-haired computer analyst for the Minneapolis Police Department, pulls up a map of the Twin Cities on his screen.
"Here, here, here," he begins, pointing to six red dots. Each marks a robbery probably committed by the same man.
"And here," Hughes continues, pointing to a dot just northeast of Minneapolis, "is where I predicted he would go next."
Simple as a crime map, seemingly as far-fetched as ESP, such scenes are becoming more common. Police departments from Minneapolis to Los Angeles are turning to the emerging science of using recent crime data to predict where criminals will strike next.
