Authorities are conducting a search for a missing grandmother in Pennsylvania who is believed to have fallen into a 30-foot sinkhole while searching for her lost cat. Despite efforts by rescue teams, conditions in the area have slowed down the search, with officials indicating that the situation has become too dangerous due to unstable mine shafts. Searchers do not expect to find the woman alive, and the focus is shifting from rescue to recovery as fears grow for both the missing woman and the safety of the rescuers. A shoe believed to belong to the woman has been found, further deepening concerns that she may have been swallowed by the sinkhole.
