EPISODE 10: The Long Island Monster - Part 2:

A serial killer has been abducting sex workers and leaving their bodies near a popular beach on Long Island for decades.

The killer has yet to be caught — but theories abound. Is it a local police officer? Or a doctor? Or is it a network of killers operating in the shadows?

We follow amateur detectives —anyone from bankers to haunted house employees, who think they might have the ability to solve this case using the power of the internet.
