History & local legend
The former St. Mary's Episcopal Church in Beaver Falls became a Widmer Engineering office in the early 1990s. The property had a longstanding connection with burials: a granddaughter of land donor James Patterson wrote that three of his children had been buried where the church stood. Their remains were relocated during the office conversion.
A later account associated the building with slamming crypt doors, footsteps, children's laughter and the sound of breaking glass. The United Paranormal Investigators Association listed Widmer Engineering among its cases.
