A ragtag squad of Chicago-based paranormal investigators explain their work, along with some spooky stories.

 

Dave Olson, a Chicago police officer, and Matt Perry, a Chicago firefighter, double as the Chicago Paranormal Investigators. When they bring their equipment to haunted spaces, they often find more than anyone else might expect.
