Several blocks away, Harris’ wife, Holly Harris, felt the impact. “It was almost like more a pressure from the bottom up and the windows and the glass just blew, and then all the ceiling fell in on us and stuff was everywhere and you just start running,” she said. “That’s the only thing you know to do.”

She started calling her husband’s phone. It kept ringing.

“He’s busy,” she thought. “He’s helping people.”

But as time went by, she said, “I knew that he would call me if he could.”

The next day, she found out he had died. One firefighter friend stayed with his body all night until it was cleared to be removed from the horrific scene.
