Workers injured in Florida parking garage collapse (12/6)
One person was missing, but police did not know if the worker was trapped or had escaped. Search crews with dogs were looking through the rubble.
The collapse occurred about 6:30 a.m. as construction workers were pouring concrete on the sixth floor of the garage for a condominium complex.
At least 15 people were hospitalized; seven others were treated at the scene, according to WSBTV.com in Atlanta.
"I heard a crack, and then it just crumbled," Rick Caldwell, a construction worker, told The Florida Times-Union.
Mayor John Peyton said at a news conference that the collapse occurred at shift change when workers were arriving and leaving work.
Jacksonville Fire-Rescue officials said the workers injured in the collapse are stable and that none of the known injuries appear to be critical. They are treating the collapse site as a "mass-casualty event."
OSHA is investigating the collapse, according to AP.
