 The emergency workers and locals in the Bronx area of New York were taking refuge in a school on Monday night after a corner of a seven-story apartment building collapsed, leaving apartments exposed like a stack of shelves and a convenience store partly buried under bricks and wood. I rush outside and all you see is the big debris cloud of smoke, all the stuff in the air and people running and screaming," said Julian Rodriguez, who works at a deli near the partially collapsed building. There were no reports of injuries as of early evening and the proprietor of the ground floor shop said the people inside got out safely, city officials said, but firefighters used buckets, power tools, and heavy equipment to pick through the debris while officials kept a watchful eye on the portions of the building that remain standing officials were looking into what caused the collapse, which happened at a 1927 building that had been undergoing façade repairs. A corner of the building stood with its walls sheared off and floors sagging, with a heap of debris spilling out into the street. By the way, in one apartment, a bed stood feet away from the edge of a floor that now jutted out into the air. In another, art hanging on the wall was visible. Elsewhere, an armchair rested on a floor that tilted precariously down, like the top of a staved-in box.
