[narrator] At first sight,
some believe the culprit was the weight
of the 57 cars
parked on the roof. They accumulated more cars
that just created more load
on top of the roof, which was one
of the contributing factors
to the building collapsing. [Brendan] While there's little
doubt what triggered
the collapse, a parking lot is designed
to hold cars, {\an8}whether it's on the ground
or up on the roof
