SBWUY Episode 35: Missing 411

This episode I dive into the mysterious cases that have stumped investigators for the past 7 decades, and they all originate in our Country's National Parks. I look at 5 cases in particular that have such strange occurrences it defies normal logic. Could an Apex predator we know nothing about, be hunting humans in our National Parks? Or could there be supernatural forces at play that leave little to no evidence of an abduction? You decide.
