    Algorithm Ep. 1 Exclusive Listen

    Hi, Monster fans! Since you enjoy our podcast, we think you'll also like the new true-crime podcast, Algorithm. Check out the first episode to see for yourself!
    About Algorithm: When Afrikka Hardy was strangled in 2014 it seemed completely random, but it wasn’t. It was part of a pattern. Four years earlier, reporter Thomas Hargrove had created an algorithm to detect serial killers and flagged Gary, Indiana as the site of an unusual number of strangulations. But when Hargrove reached out to warn local police he was ignored -- until Afrikka Hardy was murdered, and those cold cases suddenly didn’t look so cold. Algorithm follows the investigation into Afrikka’s murder, exposing the warnings that police ignored, and uncovering more than anyone expected -- that a serial killer was strangling women in Gary, Indiana could've been stopped. And that Afrikka Hardy should be alive today. This podcast will explore how technology can be used to identify and track serial killers, and how an algorithm can influence the way homicides are investigated all across the country.
