Rescue officials arrive at the scene to assess the damage of Tuesday afternoon's dramatic collapse. The New York City street where a parking garage collapsed, killing one person and resulting in five others pulled from the structure, remained closed a day later Wednesday, as investigators have yet to disclose the suspected cause behind the building reportedly with four active violations suddenly caving in by Lower Manhattan's Financial District. At a press conference Tuesday, NYC Department of Buildings Acting Commissioner Kazimir Vilenchik described how drone footage showed how the four-story building on Ann Street, between Nassau Street and William Street, "all the way pancaked, collapsed all the way to the cellar floor." He acknowledged that an active violation on the building dated to 2003. The buildings commissioner said an application was filed in 2010 but did not indicate whether the violation was corrected.

A four-story parking structure has collapsed in the United States city of New York on Tuesday, killing at least one worker and injuring five others who were in the building, authorities said. Emergency personnel deployed robotic devices after firefighters were pulled back from the fallen structure because of unstable conditions. Those robots continued to check the site for any further casualties, but authorities said they believed everyone who was in the building had been accounted for. No foul play was suspected. "We have no reason to believe that it was anything other than a structural collapse," City Police Commissioner Keechant Sewell told reporters.
