A witness told told CBS 11 News that the critically injured person was struck by debris. She was wearing business attire, the witness said and seemed to be in a hurry. The woman was taken away on a stretcher by firefighters.

No word on her condition.

Another witness who walking near the building when the scaffolding fell talked about how loud it was.

“It almost looked like when it fell, it almost looked like a slinky coming down. You know what I mean? It just kinda curved like that? And then there was a big cloud of smoke that came out when it all hit the ground,” described Justin Rhodes. 

A bystander took images and video of a construction worker holding on to the side of the building, six stories up. The worker, who still had his safety gear on was not injured.

The third person who was hurt, was also treated and released.
