Ghosts in the Museum?

My sister is a keeper at the University of Pennsylvania's Museum of Archaeology and Anthropology. For years she's been telling me that weird things happen there - elevators with minds of their own, strange noises, sights in the basement and galleries, etc. Recently a surveillance camera in the Etruscan gallery where she works caught a ghostly figure. Check it out below:

On October 22, the Young Friends of the Museum will couple up with The Free Spirit Paranormal Investigators to investigate the unexplained happenings.  Read more here.
