I saw my first full body apparition in Marysville of a woman who died in her home of alcohol poisoning. I saw the woman walk from one loft to another loft and vanish. The Citrus Heights case where 5 investigators including myself could hear a girl entity giggle and say 'hi' to me. Then later we have a séance and the walls sounded like they were ripping apart, later we hear a series of knocks on the wall. The finale was when a walkie talkie turns on and a man's voice says loudly: "Get out!"
