Witnesses are blaming the weight of a crane used by a building painter on the collapse of an underground parking garage in Windsor, Canada. Everyone's accounted for, but they're dispatching search teams just in case. (h/t to danio3834!) [Windsor Star]
I'm no structural engineer, but I can't imagine that the weight of that crane really did it, considering that the top floor still has... 6 spaces available? Look how uniformly that collapsed, it doesn't seem like a heavy weight concentrated in one spot would cause a collapse of that nature.
