The granddaughter was in good condition despite freezing temperatures, police said.About 15 to 20 feet from Pollard’s car, authorities found the sinkhole.With the rescue and recovery complete, engineers will work to fortify any points of possible erosion. “They’re going to talk about putting a grout in there, eventually and shoring up the entire entire area,” Limani said.With abandoned mines dotting much of southwestern Pennsylvania, authorities urged residents to keep an eye out for possible sinkholes and call the state. “My hope is that a tragedy like this never happens again,” Unity Township Supervisor Mike O’Barto said.
