Transcript for Rescuers Still Searching for Victims in Philadelphia Building Collapse
Tonight the exhausting search for victims of a collapsed building in philadelphia has come to an end. But it ended with a ray of light. Our cameras were there when a woman was rescued from the rubble. 13 hours after the walls came crumbling down. Here's abc's ron claiborne. Reporter: Late this afternoon, rescue teams completed their search of the rubble. They've found no one not since late last night when amazingly a 61- year-old woman was brought out, injured but alive. She'd been buried in the debris for 13 hours. We had access to her, but as soon as we cleared an area for her, and she could get out, she tried to get out on her own. Reporter: Rescue teams used dogs, and motion detectors, even tracking cellphone signals to their owners, to know where to dig. Among the dead, a 24-year-old student who was shopping at the store that was crushed. The woman rescued last night mura plekam was lucky but others have survived trapped in collapsed buildings far longer. In the 2010 haiti earthquake, a child survived eight days buried in rubble. And earlier this year, a woman lived 17 days in the wreckage of a garment factory collapse in bangladesh. She left the hospital only today. Experts point to the rule of threes as the keys to survival you can't go three minutes without air, more than three days without water, and more than three weeks without food. But the big question here today was why it happened in the first place. There was no blocking no bracing, nothing holding it up, it was kind of standing there, blowing in the breeze. Reporter: We learned today the demolition had not been inspected by the city. It didn't have to be. It's not required. Tonight with no survivors left to be found, what's left of the collapsed building is being taken down by hand, considered the slower, but safer way. Ron claiborne, abc news, philadelphia.
