Officials say one construction worker has died and another has suffered serious injuries in the partial collapse of a parking garage at a shopping mall outside Washington, D.C.
    
Rescuers in Montgomery County, Md., worked to stabilize the structure to free the surviving worker for more than four hours on Thursday. Officials say it appears a 50,000-pound section of the parking deck collapsed outside a Macy's store.
    
A Fire Department spokeswoman says the worker was freed about 6 p.m. EDT.
    
Assistant Fire Chief Scott Graham says rescuers confirmed there are no other people inside the structure.
    
The parking deck was under construction during the collapse and was not open to the public.
