SURFSIDE, Fla. (TIP): A beachfront condo building partially collapsed Thursday, June 24 outside Miami, killing at least one person and trapping others in the tower that resembled a giant fractured dollhouse, with one side sheared away. Dozens of survivors were pulled out, and rescuers kept up a desperate search for more, according to an Associated Press report.

A wing of the 12-story building in the community of Surfside came down with a roar around 1:30 a.m. By late evening, nearly 100 people were still unaccounted for, authorities said, raising fears that the death toll could climb sharply. Officials did not know how many were in the tower when it fell.

“The building is literally pancaked,” Surfside Mayor Charles Burkett said. “That is heartbreaking because it doesn’t mean, to me, that we are going to be as successful as we wanted to be in finding people alive.” Hours after the collapse, searchers were trying to reach a trapped child whose parents were believed to be dead. In another case, rescuers saved a mother and child, but the woman’s leg had to be amputated to remove her from the rubble, Frank Rollason, director of Miami-Dade emergency management, told the Miami Herald. Video showed fire crews removing a boy from the wreckage, but it was not clear whether he was the same person mentioned by Rollason. Teams were trying to enter the building from a parking garage beneath the structure.

Gov. Ron DeSantis, who toured the scene, said television did not capture the scale of what happened. Rescue crews are “doing everything they can to save lives. That is ongoing, and they’re not going to rest,” he said.

Teams of 10 to 12 rescuers at a time entered the rubble with dogs and other equipment, working until they grew tired from the heavy lifting, then making way for a new team, said Florida Chief Financial Officer Jimmy Patronis, the state’s fire marshal.

“They’re not going to stop just because of nightfall,” Patronis told Miami television station WPLG. “They just may have a different path they pursue.”

Authorities did not say what may have caused the collapse. On video footage captured from nearby, the center of the building appeared to fall first, with a section nearest the ocean teetering and coming down seconds later as a huge dust cloud swallowed the neighborhood.

President Joe Biden promised to provide federal aid if requested. About half of the building’s roughly 130 units were affected, the mayor told a news conference. Rescuers pulled at least 35 people from the rubble by mid-morning, and heavy equipment was being brought in to help stabilize the structure to provide more access, Raide Jadallah of Miami-Dade Fire and Rescue said.
