S4 Ep86: The Box

In 1998, the body of a young boy was found beneath a billboard along a North Carolina highway. With very little to go on, authorities were not able to determine who the boy was, or who killed him. But one investigator was determined to solve the case no matter how long it took. So he kept the case file in a box beneath his desk, right in his way, so that he bumped his leg on it every time he turned in his chair. The box never let him forget, and he watched and waited for the scientific advancement that would crack the case wide open. When it finally happened, a heartbreaking story emerged, leading authorities to a small Michigan town and another unsolved murder.
