South Florida was rocked on June 24 by the partial collapse of the Champlain Towers South condominium in Surfside, which killed at least 12 people. More than 150 people are still unaccounted for.

As rescue teams work around the clock to search for survivors, it’s still early days in what’s likely to be years of investigations, tough lessons and fraught litigation. Already, Miami-Dade State Attorney Katherine Fernandez Rundle has announced plans to pursue a grand jury investigation into what happened and how it can be prevented in the future.
