Brandon Winfield, 28, who lives in a building next to the one that collapsed, said he felt lucky that he avoided injury since he had driven by the site minutes before the explosion.

“I'm alive. I'm alive," he said.

The collapse reminded him of a terrible accident that happened when he was a teenager, severing his spinal cord while participating in motocross.

"I dodged two bullets,” he said.

Eboni Thornton said that she was in a moving truck outside the building when it felt like something fell on top of the vehicle. She said the whole vehicle shook. She was shocked at what she saw when she got out of the truck.
