The search for ghosts is on at a pre-Civil War hospital in Weston once called The Lunatic Asylum West of the Alleghenies.

Rebecca Jordan, property manager for the former state hospital, says crews for the Sci-Fi Channel television series "Ghost Hunters" are filming there this week.

Atlantic Paranormal Society researchers Jason Hawes and Grant Wilson and their crew will try to debunk reports of unusual activity. People say they've heard gurneys moving down hallways and screams from inside the former shock therapy room.

Using high-tech recording equipment, the crew will search for evidence of full-body apparitions, moving shadows and electronic voice phenomenon to determine whether the building is haunted.

It's not clear when the program will air.
