Surfside, Fla. (AP) -- Demolition crews set off explosives late Sunday that brought down the damaged remaining portion of a collapsed South Florida condo building, a key step to resuming the search for victims as rescuers seek access to new areas of the rubble. A loud rat-at-tat of explosions echoed from the structure just before 10:30 p.m. Then the building began to fall, one floor after another, cascading into an explosion of dust. Plumes billowed into the air, as crowds watched the scene from afar. Miami-Dade County Mayor Daniella Levine Cava told the Associated Press after the demolition that crews had been given the all-clear to resume their search-and-rescue mission to locate the 121 people believed to be missing under a wing of the Champlain Tower South that collapsed June 24. So far, rescuers have recovered the remains of 24 people. No one has been rescued alive since the first hours after the collapse. On Sunday, Miami-Dade police identified David Epstein, 58, as one of the two dozen people known to have perished in the fallen tower. His remains were recovered Friday. The demolition went “exactly as planned,” she said. “It was picture perfect. Exactly what we were told would happen.” Read more: https://trib.al/0UTevgt Subscribe to our YouTube channel: https://bit.ly/2TwO8Gm Bloomberg Quicktake brings you live global news and original shows spanning business, technology, politics and culture.
