In 1993, a family was found murdered in their home. A Maryland police spokesperson described the homicide investigation as the most “exhaustive and labor intensive” in the department’s history. And then investigators found a strange manual - written by someone calling themselves Rex Feral.

This episode was originally released in 2018.
