KNOXVILLE (WATE) - For years some people have felt the employees of WATE 6 News aren't the only ones walking the hallways of Greystone mansion, and they may be right.

On Saturday night, the mansion, which is the home of our news station, was the focus of Appalachian Paranormal Investigations.

"Paranormal is anything that can't be explained," said Joshua Ooten, co-founder of Appalachian Paranormal. "It doesn't have to be a ghost or anything like that. It just has to be something strange happening."

Ooten says their job is to try to explain the unexplained. "We always hope that it could be something paranormal because that's exciting, but we're never going into it looking for that."

"We're trying to figure out every possible scenario that could cause these things to happen without it being a ghost," he added.

What the group was looking for was any evidence of Maj. Eldad Cicero Camp, Jr., who served with the Union during the Civil War. He began building Greystone in 1885.

Since his death at the mansion in 1920, some feel the major has never really left.

"Hopefully we can come to a conclusion of what he actually wants and why he haunts all these people so much," said Appalachian Paranormal investigator Jessie Hackworth.

Armed with cameras, thermometers and various listening devices, the crew of six people had all angles covered in case the major, or someone else, decided to show.

"We have four infra-red cameras we will be using tonight to monitor areas. The second floor has a door that closes by itself. We are going to keep one of our cameras on that all night long so if that door shuts by itself, we will catch it," Ooten said.

"One of the cleaning ladies here said she caught some cell phone video of something moving around on the second floor so we will have a camera set there. If Maj. Camp happens to show up, that's a plus for us," he added with a laugh.

We won't know the group's official findings for another few weeks, but they say they believe they have proof of as many as five ghosts roaming the halls.

This isn't the first time ghost hunters have investigated the halls of Greystone. In 1988, Pat Sisson said she detected the presence of a man, possibly Maj. Camp, near one of the fireplaces, as well as a 16-year-old girl who wasn't well.
