Workers place a protective tarp on the mound at the partially collapsed 12-story oceanfront condo, Champlain Towers South in Surfside, Fla., on Sunday, July 4, 2021. Demolition specialists finished boring holes and began laying explosives in them Sunday as they prepared to bring down the precarious but still-standing portion of a collapsed South Florida condo building, a top Miami-Dade fire official said. The work has suspended the search-and-rescue mission, but officials said it should eventually open up new areas for rescue teams to explore. (Al Diaz/Miami Herald via AP)
