Now, images of the scene show an empty space where hundreds of people once lived.
Even as time went on and the possibility of finding survivors diminished, crews on the ground remained dedicated to the arduous task of combing through the rubble, pausing only for dangerous weather and when the remains of the building were demolished.
Officials promised families that the search would not end until every loved one was recovered.
“On the original collapse site, we are almost at the bottom,” Miami-Dade Police spokesperson Alvaro Zabaleta told CNN last week. “Does that mean we are almost done with the search? No. Until we clear the entire site and find no more human remains we are not done.”
All that is left are a handful of scattered concrete stumps in the imprint of the building.
Path cleared for investigators
“Until they do their job, we can’t go in to do samples of materials and take those samples and test them to understand what the various components of the building that came down was,” structural engineer Allyn Kilsheimer told CNN’s Ana Cabrera.
The first night that he was on the scene, Kilsheimer, who also investigated the aftermath of the 9/11 attack on the Pentagon, said he had about 20 or 30 theories of possible triggers.
Since then, he eliminated some but added five or six more, he said, but won’t be able to narrow it down while the search continues.
Florida State Attorney Katherine Fernandez Rundle has acknowledged “multiple requests by engineers and attorneys” to gain access to the site.
“Engineers from the federal agency National Institute of Standards and Technology (NIST) were deployed to Surfside with Congressional authority to gather evidence and determine how and why the Champlain South Tower collapsed. NIST is the fact-finding agency responsible for investigating building collapses such as the World Trade Center, much like the NTSB investigates plane crashes,” Rundle said in a statement.
“It is my understanding that once NIST, the Miami-Dade Fire Rescue and Miami-Dade Police Departments determine that it is safe and appropriate for others to gain access to the site, they will be permitted to do so under guidelines set forth by those agencies,” Rundle said.
The agony of waiting
Many families now have answers in questions over the fate of their loved ones, marking a new chapter in their mourning.
In the days after the collapse, Debbie Hill’s father was considered missing, and not knowing where he was and what happened to him was “the big issue,” she told CNN’s Erin Burnett.
Nicole Ortiz said the agony of waiting to learn the fate of her sister and nephew was indescribable.
“I screamed,” she told CNN’s Ryan Young. “I’ve almost fainted. I’ve cried.”
The community is now mourning their loved ones, as well as Vishal and Bhavna Patel and their 1-year-old daughter Aishani. Ilan Naibryf’s family is saying goodbye to a young man they said made an impact everywhere he went. Sergio Lozano is coping with the loss of both of his parents, Antonio and Gladys.
“They died together,” Lozano said. “It’s not fair — being crushed, being destroyed. It’s not fair.”
