An apartment building in Florida partially collapsed in the early morning hours of Thursday morning (June 24) .

A resident who lives in the building said he woke up to “a bang that just kept on going,” according to the Miami Herald.

Miami-Dade County Fire Chief Ray Jadallah said during a news conference that 55 units collapsed, and that 35 residents were rescued from the building. Two people were removed from the rubble.One person died, 10 people were treated at the scene and two were taken to a hospital, he said.

Miami-Dade Police Director Freddy Ramirez said that at least 99 people remain unaccounted for, according to South Florida outlet Local10.

Miami-Dade Commissioner Sally Heyman told CNN that it was unclear if all of those unaccounted for were in the building when it collapsed because of “vacations or anything else, so we’re still waiting and unfortunately the hope is still there, but it is waning.”
