Searching for survivors in deadly Philadelphia building collapse – Don Lemon reports

FROM CNN WIRES:

Equipped with search cameras, microphones and motion detectors, and bathed in harsh LED lights that illuminated the darkness, rescue workers combed through piles of bricks and rubble early Thursday, listening for the faint tap-tap-tapping of life buried in the ruins of a collapsed building.

A day earlier, the side of a building under demolition had given way and toppled onto a Salvation Army thrift store next door.

Throughout the day Wednesday, dispirited emergency responders had carried out six people in body bags. But they received a momentary jolt of joy when, shortly before midnight, they pulled out 61-year-old Myra Plekam alive.

She was the 14th survivor.
