WELLSBURG, W.Va. -- It has been determined that bones found by ghost hunters inside a historic West Virginia home are those of various farm animals.

The psychics were looking for paranormal activity in Aspen Manor in Wellsburg, near Steubenville, but found the bones hidden inside a wall instead.

Officials from the Smithsonian Museum determined that none of the bones were human. The bones ranged in size from those of either horses or cattle, to those of chickens. Pig bones were also identified in the mix, officials said.

The psychics said they sensed someone was buried in a basement wall and heard a voice saying, "Help me. I'm stuck inside the wall."

That's when they started chipping away, finding the bones.

The sheriff said the bones were chopped up and had saw marks.

"Saw and chop marks on the bones indicated that the bones were waste products of food processing, specifically butchering," officials said.

During the Brooke County Sheriff's Office investigation, it was determined that over the years, a large amount of animal butchering had occurred in conjunction with the operations of the Knights of Saint George farm, which is now referred to as Aspen Manor.

It is still undetermined why the bones were inside a basement wall.

The mansion's owner said he wasn't surprised by the find.

"I've had a couple of friends who were psychics walk through and they've had very bad reactions to different rooms in the house," said Gene Valentine.

Deputies also found glasses, hair and other items in the wall.
