SURFSIDE, Florida (AP) – It’s Day 6 of a painstaking effort to find survivors after after the collapse of a beachfront Florida condominium. Twelve stories of debris have flattened like a stack of pancakes, with layer upon layer of wreckage frustrating efforts to find pockets where someone might have survived. It’s deliberate work, and treacherous: Thunderstorms rolled through Surfside Tuesday, and debris fell overnight from the shattered edge of the remaining building. Surfside Mayor Charles Burkett said rescuers marked a “don’t go beyond here” line and are searching farther from the structure. The confirmed death toll stands at 11, with 150 people still unaccounted for.
