Once upon a time in suburban Chicago, there was a fairly ordinary suburb, with an ordinary high school, with an ordinary janitor. But it turns out the janitor’s backstory was quite extraordinary. He maintained a secret, one that would bring about worldwide manhunt to American cities in pursuit of justice. Larry Potash has the story of Oak Park and a man named Reinhold Kulle in this segment for Backstory.
