Another 61 people are potentially still unaccounted for, Levine Cava said. Detectives are still working to verify that each of those listed as missing was actually in the building when it collapsed. Levine Cava said the number of bodies recovered has put a strain on the Miami-Dade Medical Examiner's Office, with the medical examiner from neighboring Broward County now helping. More than 13 million pounds of concrete and debris have been removed from the site, with 60 trucks working to haul it away per day, officials said. "The pile that was originally four or five stories. It’s now almost at ground level. So the progress that our search and rescue teams are making is really incredible," Surfside Mayor Charles Burkett said.
