Rescuers were contemplating the safest way on Wednesday to search for a woman who apparently fell into a Pennsylvania sinkhole while looking for her lost cat, saying a crumbling old coal mine was complicating efforts and endangering workers.

Crews worked through the night in the Unity Township community of Marguerite to find Elizabeth Pollard, 64.
