Mayor Michael Nutter suggested at a late night news conference on Wednesday that the number of casualties could rise.
"We still do not know how many people were inside the thrift store or possibly on the sidewalk" at the time of the collapse, Nutter said. "If someone else is in that building, they will find them."
Moments after the Mayor made those comments, a 61-year-old woman was pulled from the rubble alive, more than 12 hours after the collapse, and taken to a hospital in critical condition.
The collapse took place when a 4-story building, which was being demolished, collapsed onto the two-story Salvation Army Thrift Store, located next door.
