Limestone Panels Fall 22 Floors Oklahoma City Street; Cars Damaged

Engineers are investigating why five limestone panels that had been attached to the building being renovated in downtown Oklahoma City came loose and fell 22 floors to the street below.

No one was injured when the panels fell from the First National Center Sunday night, but three vehicles were damaged. A developer told The Oklahoman newspaper it’s possible that water was able to get behind the stone after a fire on a higher floor, and that freezing weather may have popped the panels from their bolts.

A downtown street was closed while workers determine what happened.

There had been a small fire on the 26th floor in November. It’s possible rain or water seeped behind the limestone.

Work crews will put up scaffolding to protect pedestrians.
