Rescue teams in Pennsylvania are searching for a grandmother, Elizabeth Pollard, who may have plunged into a sinkhole while looking for her missing cat. The search is ongoing, with heavy machinery deployed to examine the site and crews working above and below ground. The family of Ms. Pollard reported her missing after she went to search for her cat, Pepper, on Monday afternoon. The sinkhole, which is at least 9m deep, is believed to be linked to the Marguerite Mine, last operated in 1952. The rescue teams are optimistic about finding Ms. Pollard alive, but they need a little bit of luck on their side. The search is ongoing, with rescue teams working through the night to find her.
