Engineers pointed back towards ceiling panels at the scene of last night's fatal ceiling collapse.

The car was partially crushed under at least four ceiling panels. The vehicle was in the left lane, giving the driver's side more protection as panels came to rest also on a left-side service walkway that is elevated several feet above the road.
