WASHINGTON, Dec 4, (AP):  A grandmother looking for her lost cat apparently fell into a sinkhole that had recently opened above an abandoned western Pennsylvania coal mine and rescuers worked late into the night Tuesday to try and find her. Bright lights illuminated snow flurries and various equipment at the site while crews worked above and below ground, video from the scene showed.

Crews lowered a pole camera with a sensitive listening device into the hole in Marguerite on Tuesday morning but it detected nothing. A camera lowered into the hole showed what could be a shoe about 30 feet (9 meters) below the surface, according to Pennsylvania State Police spokesperson, Trooper Steve Limani. "It almost feels like it opened up with her standing on top of it,” Limani said.

The family of Elizabeth Pollard, 64, called police at about 1 am Tuesday to say she had not been seen since going out Monday evening to search for Pepper, her cat. Police said they found Pollard's car parked near Monday's Union Restaurant in Marguerite, about 40 miles (65 kilometers) east of Pittsburgh. Pollard's 5-year-old granddaughter was found safe inside the car.

The manhole-sized opening had not been seen by hunters and restaurant workers who were in the area in the hours before Pollard's disappearance, leading rescuers to speculate the sinkhole was new. Authorities used an excavator to dig in the area, where temperatures dropped to below freezing overnight. "We are pretty confident we are in the right place.

We’re hoping there is still a void she could be in,” Pleasant Valley Volunteer Fire Company Chief John Bacha told Triblive. By late afternoon, searchers were using access to a mine to try to find her and had dug a separate entrance out of concern that the ground around the sinkhole opening was not stable. Authorities vowed to keep searching for Pollard until she is found.

Pollard lives in a small neighborhood across the street from where her car and granddaughter were located, Limani said. The young girl "nodded off in the car and woke up. Grandma never came back," Limani said. The child stayed in the car until two troopers rescued her. It's not clear what happened to Pepper.
