There is a new video out that is done by a forensic engineering company that shows how and why our mall collapsed last June.
Some of the footage is taken from the hotel security cam that shows the SUV falling through the roof at the moment of collapse.
One quote states "The beams appeared as if to be in a marine environment for years"

Scary stuff!
I wonder why it didn't occur to anyone that road salt would corrode steel support beams when it was designed and constructed?, it seems obvious.
