Helllo,
I saw security cameras near the elevators on each floor, but in the parking area. Also, I can see how the car went through the wall....the parking bumps are on the left of each stall and, to me, it looked as though the driver had parked on the end and drove straight ahead after rounding the bend. If the driver drove to the right side of the parking stall, it would have been really easy to miss the parking bump and plow straight in the concrete wall (it's only two or three feet) and on to the ground below.
And that's my story...
