Jackson’s son Jermaine, involved in the dispute tweeted, “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.”
The missing persons report follows a letter made public Wednesday in which two daughters — Rebbie and Janet — and three sons — Jermaine, Randy and Tito — charge that Jackson, 82, was being mistreated by the executors of Michael Jackson’s estate and mis-advised by her manager and lawyer.
According to Jackson’s lawyer, Sandra Ribera, Jackson left her Calabasas, California, home on July 15, to fly to Albuquerque, New Mexico, to attend a Jackson brothers concert two days later.
Traveling with her was her oldest daughter, Rebbie.
But when Paris, Michael Jackson’s 14-year-old daughter, called her aunts Rebbie and Janet over the past several days, she was told each time she could not speak to her, Ribera said.
“yes, my grandmother is missing . i haven’t spoken with her in a week i want her home now,” Paris tweeted Sunday morning.
In another tweet, she gave out her bodyguard’s phone number and asked people to call the authorities if they saw Jackson.
“The kids were trying to get a hold of their grandmother and they haven’t been able to reach her for almost a week,” Ribera said. “They are told she’s unavailable.”
“I’m concerned that she’s not safe,” Ribera added.
Jackson has not called Michael Jackson’s three children, who have lived with her since their father died three years ago, the lawyer said.
Jackson “has never gone 24 hours without talking to her kids,” she said.
“I’m concerned that she would never do this,” Ribera said. “We have no idea what’s going on with her. No one has talked to her.”
CNN reached out to Janet Jackson’s representatives several times but did not hear back.
Jackson’s manager Lowell Henry questioned Jermaine Jackson’s claim that a doctor ordered her to leave her home and not communicate with her grandchildren.
The sheriff’s homicide-missing persons unit has been asked to investigate, Ribera said.
Katherine Jackson has been taking care of Michael Jackson’s three children – Prince, 15, Paris, 14, and Blanket, 10, – since Michael’s death in June 2009.
