South Florida officials on Wednesday called off the search for survivors, burying hopes that there was any chance to pull someone out alive.

The two-week search was saturnine and treacherous with the threat of a tropical storm hovering, as pile of bodies gradually mounted.

The painstaking search for survivors shifted to a recovery effort at midnight Wednesday.

“We have all asked God for a miracle, so the decision to transition from rescue to recovery is an extremely difficult one,” Miami-Dade Mayor Daniella Levine Cava said at a news conference.

The death toll stood at 54 late Wednesday. Officials said 86 people were unaccounted for, although detectives were still working to verify that each of those listed as missing was actually in the building when it collapsed.

Rescuers had spent two weeks digging through the rubble, searching in vain for any sign of life, Levine Cava said.

“They’ve used every possible strategy, and every possible technology available to them to find people in the rubble,” she said.

“They’ve removed over 7 million pounds of concrete and debris from the mound. They’ve used sonar, cameras, dogs, heavy machinery. They’ve searched for void spaces and they’ve searched for victims. They ran into a building they were told could collapse, and they braved fire, smoke, torrential rain, and strong winds in the hopes of finding people alive.”

Hours before the formal transition from rescue to recovery mission, those emergency workers joined local officials, rabbis and chaplains in a moment of silence.

An accordion player unseen on a nearby tennis court played Aaron Copland’s “Fanfare for the Common Man,” which was followed by a piccolo playing “The Battle Hymn of the Republic.”

Firefighters from Ohio, Pennsylvania, New Jersey, the federal government and elsewhere were also present.

On a tall nearby fence, families and well-wishers had posted photos of the victims, supportive messages and flowers. Firefighters hung a banner atop the fence that read “Miami-Dade Fire Rescue Mourns With You.”

Officials vowed to continue the recovery efforts until they find the remains of every one of the missing.

Miami-Dade Assistant Fire Chief Raide Jadallah told families during a private briefing that crews would stop using rescue dogs and listening devices.

“Our sole responsibility at this point is to bring closure,” he said, as relatives cried in the background.

Later, during a news conference, Jadallah said crews remained committed to doing whatever it takes to finish the job.

“The resources are still there. The men and women are still there. The support is still there,” said Jadallah, who began crying silently after he spoke.

Miami-Dade Fire Rescue Chief Alan Cominsky said he expects the recovery effort will take several more weeks.

Hope of finding survivors was briefly rekindled after workers demolished the remainder of the building, allowing rescuers access to new areas of debris.

Twice during the search operation, rescuers had to suspend the mission because of the instability of the remaining part of the condominium building and the preparation for demolition.

After initially hoping for miraculous rescues, families had slowly braced themselves for the news that their relatives did not survive.

“For some, what they’re telling us, it’s almost a sense of relief when they already know (that someone has died) and they can just start to put an end to that chapter and start to move on,” said Miami-Dade firefighter and paramedic Maggie Castro, who has updated families daily.

Authorities are launching a grand jury investigation into the collapse and at least six lawsuits have been filed by Champlain Towers families.
