Philadelphia Building Collapses; At Least One Dead

From NBC:

A building in downtown Philadelphia has collapsed, crushing a nearby structure and killing one person. Authorities have rescued 13 people and are digging to see if anyone else remains trapped beneath the rubble.

“I was parked on 21st just heading to Market Street, next thing you know it felt like an earthquake," said Bernie Ditomo, a truck driver with Belfi Brothers. "I said, 'What the hell is going on?' My truck is totaled. I am a little dusty and dirty, but I’m alright. I am one of the lucky ones.”

The collapse at 2140 Market Street happened around 10:40 a.m. when a four-story building came down on top of a two-story building, which housed a Salvation Army Thrift Store. Early reports from Philadelphia Police indicate that the collapse may have been the result of an industrial accident, as construction crews were working on the nearby structure.

"This is a delicate and dangerous operation," Mayor Michael Nutter said of the rescue and recovery effort during a press conference from the scene. "We did not know and do not know how many people were actually in that store when the wall collapsed."
