Firefighters in Surfside, Florida, have ended the recovery mission from the June collapse of a condo tower that killed nearly 100 people.

The conclusion of the mission comes one day ahead of the one-month anniversary of the collapse of Champlain Towers South. Ninety-seven people were killed when the tower spontaneously fell on the morning of June 24.

In a letter to Miami-Dade and Surfside officials, structural engineer Allyn Kilsheimer, who was hired to find out why the building collapsed, said the site might be unsafe due to a perimeter wall near Collins Avenue could fail, the Associated Press reported.

In the letter, Kilsheimer recommended that an earthen berm be built to support the walls because parts of the street could collapse.

According to the Miami Herald, Miami-Dade County officials said crews would be brought in to shore up the remaining underground walls.

Collins Avenue, which has been closed to traffic since June 24, could be reopening soon, the newspaper reported.

The announcement comes a day after Miami-Dade Circuit Judge Michael Hanzman said in a hearing that victims and families who suffered losses in the collapse would be initially compensated a minimum of $150 million.

Rescue efforts at the site of a partially collapsed condo tower in Surfside, Florida, have been suspended as officials prepare to demolish the portion of the building that's still standing.

Miami-Dade Assistant Fire Chief Raide Jadallah said that first responders suspended their rescue mission at 4 p.m. ET on Saturday. He reiterated during a press conference that the demolition was necessary to keep rescue workers safe.

An emergency order approving the demolition has already been signed.

Workers will bring down the Champlain Towers South on Sunday ahead of the expected arrival of Tropical Storm Elsa.

Structural concerns about the building prompted the stoppage of search and rescue efforts for more than 12 hours on Thursday.

The tower partially collapsed in the early morning hours of June 24.

Earlier on Saturday, Miami-Dade Mayor Daniella Lavine Cava confirmed that two more bodies were pulled from the debris overnight Friday into Saturday. The additional victims bring the death toll to 24, and another 126 who are presumed to be in the building at the time it crumbled are still missing.

Eighteen of the 22 people killed in the collapse have been identified. They are:

• Hilda Noriega, 92
• Antonio Lozano, 83
• Leon Oliwkowicz, 80
• Magaly Elena Delgado, 80
• Gladys Lozano, 79
• Christina Beatriz Elvira, 74
• Maria Obias-Bonnefoy, 69
• Frank Kleiman, 55
• Staci Dawn Fang, 54
• Manuel LaFont, 54
• Marcus Joseph Guara, 52
• Michael David Altman, 50
• Anna Ortiz, 46
• Anaely Rodriguez, 42
• Luis Bermudez, 26
• Andreas Giannitsopoulous, 21
• Lucia Guara, 10
• Emma Guara, 4

Officials have also confirmed that the 7-year-old daughter of a Miami firefighter was also among those killed in the collapse.

About a block from the Miami-area beachfront condominium tower that collapsed sits its sister building, Champlain Towers North.

It was erected in 1982 — a year after the now-partially collapsed Champlain Towers South — built by the same company, using the same materials and a similar design.

It has faced the same tides and salty air.

Last Thursday's collapse has made some residents of Champlain Towers North worried enough to leave, though most have remained. They say they are confident their almost 40-year-old, 12-story building is better maintained.

They say their building doesn't have the same problems with cracking in support beams and in the pool area that 2018 engineering reports show the south tower had.

"I've never seen any major structural issues" in the north building, said Philip Zyne, an attorney. "I'm not worried at all right now. I do want to get a full structural engineering and forensic examination done."

However, some residents aren't taking any chances, like Rebecca Weinstock, who bought a sixth-floor apartment four years ago. She's currently in New York, where she plans to stay.

"I am out my investment, I am out my apartment, I am out my future, but we are talking about lives here," she told the Associated Press.

She added she'll only return to the building if two independent engineers from outside the region determine it's safe to return.
