Leonor Yupa dropped to her knees Thursday when a Spanish-language media reporter said her 22-year-old son was among eight people whose lives were claimed by the Brooklyn building collapse the day before.

The deadly collapse that occurred without warning Wednesday afternoon took down a building that housed a store selling medical uniforms on the ground level and four apartments on the floors above.

Six people were found dead in the wreckage and two others died later from their ​injuries, city officials told reporters at the scene of the collapse.
