For weeks, people working nearby had watched with growing concern as a demolition crew took down a vacant four-story building next to a thrift store at the edge of downtown Philadelphia.
A roofer atop another building didn't think the operation looked safe. A pair of window washers across the street spotted an unbraced, 30-foot section of wall and predicted among themselves the whole building would simply fall down.
On Wednesday, that's what happened. The unstable shell of a building collapsed into a massive heap of bricks and splintered wood, taking part of the Salvation Army thrift store with it and killing six people. Fourteen others were injured.
"Our thoughts and our prayers go out to those who lost their lives, and their families," said Mayor Michael Nutter at a late-night news conference at which he announced the death toll. "At the same time, we pray that those who survive will recover not only physically, but certainly mentally from the trauma of being in a building and it suddenly collapses."
Rescuers used buckets and their bare hands to move bricks and rubble in a search-and-rescue operation that was expected to last into Thursday morning.
Searchers said they would continue going through the rubble.
We're going to keep searching "until we're absolutely sure no one else is there," battalion fire chief Charles Lupre said shortly before dawn Thursday.

He said there were no reports of anyone missing, but there was always the chance that someone was inside who wasn't reported missing.
Witnesses said they heard a loud rumbling sound immediately before the collapse.
"I was standing there looking out my window, watching the men at work on the building, and the next thing I know I heard something go kaboom," said Veronica Haynes, who was on the fifth floor of an apartment building across the street. "Then you saw the whole side of the wall fall down ... onto the other building."
It was unclear what role the demolition work might have played in the collapse, but the accident raised questions about how closely the highly visible spot on Market Street, one of Philadelphia's signature boulevards, was being monitored, particularly amid word of the demolition contractor's many legal and financial troubles. Officials from the U.S. Department of Labor and Occupational Safety and Health Administration were at the scene.
Several witnesses said they had questioned how the demolition workers were tackling the job.
Roofer Patrick Glynn said he had been watching workers take down the building over the past few weeks, and he said he suspected a collapse was inevitable because of the way they were going about it.
"For weeks they've been standing on the edge, knocking bricks off," he said. "You could just see it was ready to go at any time. I knew it was going to happen."
Steve Cramer, who has been working as a window washer across the street, said the demolition crew left 30 feet of a dividing wall up with no braces and it compromised the integrity of the building
"We've been calling it for the past week — it's going to fall, it's going to fall," his co-worker Dan Gillis said.
Officials said the demolition contractor was Griffin Campbell Construction in Philadelphia. Messages left for Campbell were not returned.
Records show that Campbell was charged in 2005 with dealing crack cocaine near a playground. The charges were dismissed after prosecutors misplaced evidence.
