LOS ANGELES (AP) -- A person familiar with Katherine Jackson's whereabouts says she is resting with one of her daughters on doctor's orders.
The person, who was not authorized to speak publicly and asked to remain anonymous, said Sunday the Jackson family matriarch is with her daughter Rebbie and has been prescribed rest by a physician.
The unknown whereabouts of the 82-year-old's Jackson and her lack of communication with her grandchildren prompted a missing person report Saturday night.
Sheriff's officials in Los Angeles later said they believed she was safe and with family in Arizona but had yet to speak with her.
Katherine Jackson serves as guardian of her son Michael's three children.
Michael Jackson's daughter Paris tweeted early Sunday that she hadn't spoken with her grandmother in a week and wanted her to return home.
