Pittard reports on unexplained happenings in North Carolina's 165-year-old Capitol building in Raleigh. Workers up on scaffolds in the building have been tapped on the shoulder. Ghostly voices have been captured on tape at 20,000 hertz, well above the normal hearing range of human beings. Visitors feel cold spots. Photographers using infrared film capture images and shapes unseen by the naked eye. Investigators continue to study and analyze the reported occurrences, but to date, the building continues to keep it secrets.
