A maddening dilemma faces rescuers at the Algo Mall in Elliot Lake. They know there are at least two people alive in the wreckage but had to call off their work because they can’t figure out how some of the remaining structure continues to stand. It is just too dangerous to keep on searching. Specifically, the engineers can’t figure out why beams supporting an escalator and stairs inside the mall in Elliot Lake haven’t collapsed already.
