Mr. Carradine has investigated ghosts from all over the world, (Canada, Scotland, England, Wales, Austria, Czech Republic, and Slovenia) and throughout the United States (Florida, California, New York, Louisiana, Virginia, and Montana). In California alone, he has investigated over 200 haunted locations.His approach to each case is academic. Proving or disproving the spiritual activity of a certain spot isn't what motivates this ghost hunter. Instead, he is more interested in collecting the stories and eyewitness accounts, and archiving them, as a means of recording them for future studies into these unusual phenomena that clearly affect so many seemingly unconnected people.
