OTRC: Katherine Jackson in Arizona with family, report says

Katherine Jackson, the mother of the late singer Michael Jackson, is reportedly safe with family in Arizona, authorities believe according to The Associated Press.

An unnamed source told the wire service that Jackson is with her eldest daughter Maureen Reillette "Rebbie" Brown (nee Jackson) and is following doctor's orders to rest. Authorities are still trying to establish contact with her.

The 82-year-old had been reported missing on Saturday night and the news came amidst a dispute over Michael Jackson's estate between the executors of his will, John Branca and John McClain, and members within the Jackson family.

Several family members, including Janet Jackson, Randy Jackson, Tito Jackson and Rebbie wrote and signed an undated letter to the executors of his will claiming that it was a fake. The will reportedly left the late singer's fortune to his children, Katherine Jackson and an undisclosed amount to charity.

The letter also claims, according to The Associated Press, that Katherine Jackson has been manipulated by the executors and that she suffered a mini-stroke as a result.

"Yes, the letter is authentic," Randy Jackson wrote on Twitter on July 17. He later added in another Tweet, "We ask that everyone respects that this is a serious matter that will be handled by the proper authorities."

Jermaine Jackson stated on Twitter account that his mother had a stroke and that she was "resting up" and following doctor's advice.

"The truth is that Mother DID suffer a mini-stroke some months ago," he wrote on July 19. "She is fine now, but the timeline doesn't alter the fact it happened."

"I want to reassure everyone (inc all sudden medical experts) that Mother is fine but is resting up in AZ on the orders of a doctor, not us," he wrote on July 20. He later added, "This is our mother and her health is paramount. We are not inventing or plotting anything. We are following doctor's advice. Period."

On July 22, Jermaine Jackson wrote, " I will shortly be issuing a statement to end this wildfire of madness..."

Katherine Jackson is the guardian of Michael Jackson's three minor children and the late singer's daughter, Paris Jackson, took to her official Twitter page to express her concerns about her grandmother's safety.

"Yes , my grandmother is missing," She wrote on July 22 at 1:33 a.m. "I haven't spoken with her in a week i want her home now ."

She later added, "The same doctor that testified on behalf of Dr. Murray saying my father was a drug addict (a lie) is caring for my grandmother... just saying."

Katherine Jackson's attorney, Perry Sanders Jr. also spoke to The Associated Press on July 22, and said, "First of all, let's hope that this is all just a big misunderstanding and a totally benign situation. Assuming that she did actually leave on doctor's orders, no matter which doctor, it has certainly created an absolutely irregular situation whereby she has been out of contact with her grandchildren."

The estate has denied the letter's accusations and Jackson once obtained permission for a judge to investigate the validity of the will but never pursued the matter in court.

Michael Jackson died at age 50 in June 2009 from an accidental overdose of the anesthetic propofol and other medications in his rented Los Angeles mansion. His doctor, Conrad Murray, who prescribed the drug along with several other benzodiazepines, was sentenced to four years in jail in November after being found guilty of involuntary manslaughter.
