Katherine Jackson is safe and resting with one of her daughters on doctor's orders, a person familiar with the situation has told the Associated Press.
The person, who was not authorized to speak publicly and asked to remain anonymous, said Sunday that the Jackson family matriarch is with her daughter Rebbie and has been prescribed rest by a physician.
The 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 Department 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. Her granddaughter Paris Jackson issued a frantic plea on Twitter early Sunday.
"I haven't spoken with her in a week I want her home now," she tweeted.
The family drama unfolded days after it was revealed that some of Katherine Jackson's children had written a letter to the executors of Michael Jackson's estate, alleging his will, which left his fortune to his children, his mother and charity, was a fake.
The undated letter, signed by Janet, Randy, Tito, Rebbie and Jermaine Jackson, claimed Katherine Jackson was being manipulated by the executors, John Branca and John McClain, her health had been affected, and that she suffered a mini-stroke.
The estate has denied the accusations.
