In January 2012 Carl and I investigated the Marlboro Psychiatric Hospital in Marlboro Township, NJ. The facility closed over 10 years ago and in the process of being torn down. It's a beautiful campus with over a dozen two story buildings. While investigating the campus we placed a static High Def video camera in Building G. We let it record for over an hour. There were several loud bangs and what sounded line someone walking behind the camera.
