South New Jersey ghost hunter profiled

From the Haddonfield (N.J.) Herald:

When pictures are taken in a cemetery, a different type of phenomenon occurs. The investigators whip out their cameras when there is a drop in temperature, and the result is often a misty cloud that may be hanging over tombstones. Again, this cloud is never seen with the naked eye.

"We always go through a check list of items we rule out," Halpin said; "glare, dust on the lens, mirrored surfaces, breath on a cold night. Then, when this is all eliminated, we can theorize what might be on the photo."

She believes in the Sherlock Holmes quote: "...when you have eliminated the impossible, whatever remains, however improbable, must be the truth...

"What are these orbs or mists? What do they represent?

"They could be the spirit of dead people or a psychic recording of an event that has happened," Halpin said. "Residential hauntings, for example, are like a VCR tape that just keeps playing. Weather conditions, for example, may trigger the response, and the haunting will occur. But it won't harm you. Most of the time what you experience does not even know you are there, although sometimes, under certain conditions, you can communicate with the spirit."

I like any ghost hunter who works in a Sherlock Holmes quotation.
