Authorities have found the body of a 64-year-old woman who fell into a sinkhole above an abandoned mine in western Pennsylvania, according to news reports.

Citing state police, TribLive.com said her body was found Friday morning.

Digging had resumed early Friday in the search for Elizabeth Pollard, who disappeared Monday in Union Township, near Latrobe, while looking for a lost cat.

WTAE said drills were brought in Friday and, from the ground, crews drilled into the ceiling of the mine shaft to find Pollard.

After nearly 10 hours of digging on Thursday, crews had reached the section of the sinkhole where they believed they would find her remains, the Pittsburgh Post-Gazette reported Thursday night.

The efforts to find the 64-year-old grandmother shifted to a recovery mission on Wednesday evening after it became too dangerous to continue sending crews into the cavernous hole.

State police Trooper Steve Limani said rescue crews had been risking their lives by going into the abandoned mine, comparing the instability to “a house of cards.”

The nearby Monday’s Union Restaurant has been closed as a result.

“There’s tons of areas that have little depressions all around,” Limani said. “And those depressions are very weak spots.”

The sinkhole Pollard likely fell through had “just enough dirt” for a roof system and grass to grow, he said.

Pollard was last seen Monday evening, searching for Pepper. Her family reported her missing around 1 a.m. on Tuesday, and her car was found two hours later with her 5-year-old granddaughter inside, scared but unhurt. Pepper’s whereabouts are unknown and police said there have been no sightings of the cat in the area.

About 20 feet from Pollard’s car was a sinkhole with an opening about the size of a street manhole cover, which authorities suspect opened up as she walked across the ground toward a wooded area near the restaurant.
