UNITY TOWNSHIP, Pa. (AP) — Rescuers are contemplating the safest way to search for a woman who apparently fell into a sinkhole while looking for her lost cat above an old coal mine in Pennsylvania. They said Wednesday that the crumbling mine was complicating efforts and endangering workers. A state police spokesperson says the integrity of the mine has been compromised and rescuers are reassessing their tactics. Bright lights illuminated snow flurries and equipment at the site while crews worked above and below ground. The search began Tuesday after 64-year-old Elizabeth Pollard’s family called police to say she had not been seen since going out Monday evening to look for her cat named Pepper.
