PHILADELPHIA (AP) — The bodies of two workers trapped when a stairwell roof collapsed at a parking garage under construction in Philadelphia have been found, authorities announced Monday morning.

The section of roof at the Children’s Hospital of Philadelphia’s garage fell Wednesday, triggering a collapse across all seven levels, Mayor Cherelle Parker told reporters last week. Crews initially rescued three workers injured in the collapse and they were taken to hospitals, where one died, officials said. The other two workers were treated and released. By Thursday, officials said search dogs hadn’t found any signs of life at the collapse site.
