Rescue teams in the US state of Pennsylvania are searching for a grandmother who may have plunged into a sinkhole while looking for her missing cat, Sky News reports.
Elizabeth Pollard, 64, has not been heard from since Monday afternoon when police believe she fell into the hole in Marguerite, about 65km east of Pittsburgh.
Heavy machinery has been deployed to examine the site, while crews work above and below ground.
Search teams have also accessed a nearby mine to try to find her and dug a separate entrance because of concerns the ground around the sinkhole was unstable.
The family of Ms Pollard called police at about 1 am on Tuesday to report her missing after saying she had gone to search for Pepper, her cat.
