FRANKLIN PARK — A Zelienople man is dead after police say he fell several stories while washing windows at an office building.

The Allegheny County medical examiner’s office says 48-year-old Stephen Willoughby died from injuries sustained in the fall Wednesday afternoon in Franklin Park.

Workers at a surgical center in the building attempted CPR before medical personnel arrived, but Willoughby was pronounced dead at the scene.

He fell at least three stories while working with a lift at the building just north of Pittsburgh.

The medical examiner’s office said Willoughby was not wearing a safety harness. Police say they have contacted the Occupational Safety and Health Administration.
