This story is developing.

Firefighter who helped rescue her said: 'She was pretty well buried'." ABC News Philadelphia reports that rescuers pulled 61-year-old Myra Plekam of Kensington out of the wreckage.

Update, 9:05 PM CDT: NBC10 reports rescuers found three more bodies in the rubble tonight but have not yet revealed their identities. That brings the injured total, including those killed, to 17.

Rescue crews are carefully searching through tons of dusty rubble for at least two, possibly three, people believe trapped at the scene [See Updated Information Above]. Dogs are being used in the rescue effort. "Dozens of firefighters and emergency personnel are at the scene," reports Fox News. "A total of 12 people were hospitalized at nearby trauma centers with minor injuries and listed in stable condition." Fox also reports that the collapse "involved a Salvation Army corner thrift store and a four-story building next door with a sandwich shop on the first floor."

At 1:11 PM CDT, KIII TV reported Fire Commissioner Lloyd Ayers told reporters that two people are still trapped. "We have located them and we're going to continue until we can get them out and we can get them to hospitals," Ayers said.

KIII's report says that 12 people were rescued earlier and hospitalized with minor injuries. "Another woman walked away from the scene with no major injuries after being trapped for more than two hours," which brings the total of people freed from the rubble to 13.

Philadelphia Police are calling the collapse an "industrial accident." Investigators from the Occupational Safety and Health Administration (OSHA) are on their way to the scene. There were "no existing violations" at the building, a city building inspector said.
