Four more victims of the Surfside condo collapse were recovered overnight and into the day Friday, said Miami-Dade Mayor Daniella Levine Cava, raising the death toll to 22 as rescue workers continued the search amid the threats of shifting rubble underfoot, falling debris overhead and a hurricane in the forecast. The mayor also said during a late afternoon briefing that she signed off on the demolition of the standing remains of the Champlain Towers South building. Engineers are considering a pair of options. One would be a controlled blow that would halt the rescue effort for only a few hours. Another would take more time and involves using large cranes to haul away chunks of the building, dpa reported.
