APTOPIX Building Collapse Manhattan

A pile of debris remains at the site of a building explosion in the East Village neighborhood of New York, Friday, March 27, 2015. Nineteen people were injured, four critically, after the powerful blast and fire sent flames soaring and debris flying Thursday afternoon. Preliminary evidence suggested that a gas explosion amid plumbing and gas work inside the building was to blame. (AP Photo/The New York Times, Nancy Borowick, Pool)
