LOS ANGELES — The mother of Michael Jackson said in court papers she was kept from communicating with outsiders while at a resort in Tucson and was unaware she had been reported missing.

Katherine Jackson declared in the documents obtained Thursday that she had no idea she was the subject of a search until she accidentally heard a TV report.

She said she was told her doctor had ordered her to rest and she was flown to Arizona. At a spa, her cell phone was confiscated along with her IPad and she said she was kept in a room with no working phone or TV service.

She said she asked about Michael’s children and was told they were fine.

The disclosure marked the latest development in a series of events that began when Katherine Jackson was reported missing but later turned up at the spa with family members.

The documents were released after a judge reinstated Katherine Jackson as the guardian of the children in an arrangement that also keeps their cousin as temporary co-guardian.

Superior Court Judge Mitchell Beckloff said during a hearing that an investigator who looked into the children’s care found that the late pop star’s 82-year-old mother was an excellent guardian and the children love her very much.

“I think the kids are in terrific hands,” the judge said. “It appears from the report that Katherine Jackson has done a wonderful job and cares about the children very much.”
