The majority of the preparation for the blast at Champlain Towers South was complete Sunday morning, so the building could come down that night.

“Our top priority is that the building come down as soon as possible, no matter what time that occurs and as safely as possible,” Miami-Dade County Mayor Daniella Levine Cava told a news conference Sunday. “Bringing down this building in a controlled manner is critical to expanding the scope of our search-and-rescue effort.”

The rescue efforts were suspended so crews could demolish the building.

Rescuers have confirmed 24 people dead and were searching for 121 others who remain unaccounted for. No one has been rescued alive since the first hours of the June 24 collapse.
