Authorities have opened criminal and civil investigations into the collapse of the oceanfront condominium building Champlain Towers South, which left at least 28 dead and more than 117 unaccounted for.

Miami-Dade State Attorney Katherine Fernandez Rundle pledged to bring the matter soon before grand jurors, who could recommend criminal charges or simply investigate the cause to suggest reforms.

And at least five lawsuits have been filed on behalf of residents who survived or are feared dead. One lawyer involved in the litigation said the collapse raises widespread concerns about infrastructure issues and the trust we put in those responsible for them.

“We deserve to be able to walk into buildings without worrying that they’re going to come crumbling around us and to know that our loved ones can go to bed at night without worrying that they’re going to plummet 12 stories to the ground below in their sleep,” said Jeffrey Goodman, whose Philadelphia-based firm filed suit on behalf of the children of missing resident Harold Rosenberg.

The lawsuits filed to date accuse the Champlain Towers South Condominium Association, and in some cases a local architect and engineer, of negligence for failing to address serious structural problems noted as far back as 2018.

A Surfside town building inspector had also been part of the discussions, and Goodman’s firm has given notice of plans to add the town as a defendant.

At a hearing Friday, a judge appointed a receiver to represent the condominium association’s interests given the trauma experienced by board members, one of whom remains missing. The board has about $48 million in insurance coverage, while the oceanfront land is valued at $30 million to $50 million, the judge was told.

The judge said he hoped the litigation could be resolved quickly, perhaps within a year. Until then, he authorized the receiver, attorney Michael Goldberg, to provide $10,000 each to residents for temporary housing and $2,000 to cover funeral expenses.

Attorney Robert Mongeluzzi, who also represents the Rosenberg family and is seeking access to the site, said cases such as these are not just about the money.

“They want to make this a quest to find out what happened,” Mongeluzzi said.

One prior case with possible legal parallels involves the 2013 collapse in Philadelphia of an unbraced wall of a building that was being demolished. It toppled onto an adjacent Salvation Army store, killing six people and injuring 13, with one woman found alive 13 hours later losing both legs and forced to endure more than 30 surgeries before her death this year.

In the trials that followed, a civil jury found the Salvation Army, the building’s owner and his architect largely responsible, and the parties agreed to pay $227 million in damages.

On the criminal side, the architect received immunity in exchange for cooperating with prosecutors.

The collapse also prompted the city of Philadelphia to send inspectors out to examine demolition sites and led to toughened regulations.

In Florida, a grand jury is still reviewing the 2018 collapse of a pedestrian bridge at Florida International University that killed six people. And both manslaughter and third-degree felony murder charges were filed following the 1996 accidental crash of ValuJet 592 in the Everglades that killed 110 people.
