ST. PETERSBURG, Fla. (AP) — The ground-floor pool deck of the oceanfront condominium building that collapsed near Miami was resting on a concrete structural slab that had “major structural damage” and needed to be extensively repaired, according to a 2018 engineering report that also uncovered “abundant cracking and spalling” of concrete columns, beams and walls in the parking garage.

The report was among a series of documents released by the city of Surfside as rescuers continued to dig Saturday through rubble in an effort to find any of the 159 people who remain unaccounted for after the collapse. At least four people were killed.
