A smoldering fire beneath the rubble that produced thick smoke and hindered the work of rescuers has abated, officials said. A trench was dug to separate the areas of smoking debris from the rest of the rubble and rescuers are also using tunnels, Levine Cava said.
Some families of those missing have provided DNA samples to officials while others recounted narrow escapes. Police released the names of four victims who ranged in age from 54 to 83.
Surfside officials have released documents including an engineer's report from 2018 that found major structural damage beneath the pool deck and "concrete deterioration" in the underground parking garage of the 12-story condominium.
The report was produced for the Champlain Towers South condominium board in preparation for a major repair project set for this year.
It was not immediately clear whether the damage described in the report was connected to the collapse about 1:30 a.m. on Thursday.
