Search and rescue teams look for survivors at the Champlain Towers South residential condo, Tuesday, June 29, 2021, in Surfside, Fla. Many people were still unaccounted for after Thursday's fatal collapse.

SURFSIDE, Florida — Elected officials pledged Tuesday to conduct multiple investigations into the collapse of an oceanfront Florida condo tower, vowing to convene a grand jury and to look closely “at every possible angle” to prevent any other building from experiencing such a catastrophic failure.

Miami-Dade County Mayor Daniella Levine Cava said she and her staff will meet with engineering, construction and geology experts, among others, to review building safety issues and develop recommendations “to ensure a tragedy like this will never, ever happen again.”

State Attorney Katherine Fernandez Rundle said she will pursue a grand jury investigation to examine factors and decisions that led to Thursday's collapse of the 12-story Champlain Towers South in Surfside. Another victim was recovered Tuesday, bringing the confirmed death toll to 12, with 149 people unaccounted for.

Even as officials looked to the future to determine the cause of the collapse, they were resolute in vowing to continue the effort to find survivors.

On the sixth day of a painstaking search, Gov. Ron DeSantis evoked a well-known military commitment to leave no one behind on the battlefield and pledged to do the same for the people still missing in the rubble.

“The way I look at it, as an old Navy guy, is when somebody is missing in action, in the military, you're missing until you're found. We don't stop the search,” DeSantis said at a news conference.

“I think that's what is happening. Those first responders are breaking their backs trying to find anybody they can. I think they are going to continue to do that. They've been very selfless. They've put themselves at risk to do it.”
