Some of you know that I belong to Vancouver Supernatural, a paranormal group in my home town of Vancouver, BC. We were recently on an investigation at the Royal Crown Castle Restaurant and Pub in New Westminster (suburb). Not only is the castle a heritage building, but it once served as part of the British Columbia Penitentiary, and still has what used to be prisoner cells in the basement.
Our SLS camera (think Xbox Kinect) mapped out someone who wasn't in the room. Watch the video and pay particular attention to when I ask if something is wrong with his leg (he then bends it) and when my friend Kathleen asks him to knock on the wall.
