SURFSIDE, Fla. — A beachfront condo building partially collapsed Thursday 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.

A wing of the 12-story building in the community of Surfside came down with a roar around 1:30 a.m. 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.”

Patronis said he was deeply moved by the image of a bunk bed near the now-exposed top of the building.

“Somebody was probably sleeping in it,” he said. “There’s all those what-ifs.”

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. Work was being done on the building’s roof, but Burkett said he did not see how that could have been the cause. Hotels opened to some displaced residents, the mayor said, and deliveries of food, medicine and more were being hastily arranged.
