Last-minute shift change may have saved construction worker from Key Bridge collapse

Moisés Díaz was scheduled to fill potholes on the Francis Scott Key Bridge early Tuesday morning, but a last-minute shift change may have saved his life.

"Every day we give thanks to God for life," Díaz told CBS News.

But while he's thankful, Díaz is grieving the loss of the six fellow construction workers — men he calls brothers — who died when the bridge collapsed.
