Finding Serial Killers Algorithmically

The New Yorker has an article about Thomas Hargrove who has been mining crime data to find groups of related murders that haven't been linked before.

Each year, about five thousand people kill someone and don’t get caught, and a percentage of these men and women have undoubtedly killed more than once. Hargrove intends to find them with his code, which he sometimes calls a serial-killer detector.
