Los Angeles ( CNN ) -- Paris Jackson waited at home Sunday , hoping for a phone call from her grandmother , the woman who has cared for her since her father , Michael Jackson , died three years ago . `` yes , my grandmother is missing , '' Paris Jackson , 14 , tweeted Sunday morning . `` i have n't spoken with her in a week i want her home now . '' A nephew reported Jackson family matriarch Katherine Jackson , 82 , missing late Saturday after her grandchildren were unable to get in touch with her for a week . It is the latest chapter in a messy dispute between several of Jackson 's children and her advisers over her finances and legal affairs . Jackson 's nephew , Trent , filed the report with the Los Angeles County Sheriff 's Office . But one of her sons involved in the dispute said in a series of Twitter postings Friday that Katherine Jackson was fine and resting in Arizona . `` 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 , '' Jermaine Jackson tweeted . `` This is our mother and her health is paramount . We are not inventing or plotting anything . We are following doctor 's advice . Period , '' he added . Paris Jackson 's responded to her uncle 's claim with her own tweet early Sunday . `` 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 '' she tweeted . The doctor who examined Jackson at her home on July 14 was Dr. Allan Metzger , according to Katherine Jackson attorney Sandra Ribera . Metzger was a defense expert witness for Dr. Conrad Murray last year . Murray was subsequently convicted of involuntary manslaughter in Michael Jackson 's death . Dr. Metzger was brought into Jackson 's Calabasas , California , home `` under false pretenses '' by saying he was sent by her primary care physician , Ribera said . `` We came to find out that her doctor has no association with Dr . Metzger . '' The doctor advised Jackson that it was better for her to take a plane on a trip planned for the next day , rather than ride in a RV driven by Trent Jackson , Ribera said . Jackson left with her oldest daughter , Rebbie , the next day to fly to Albuquerque , New Mexico , to attend a Jackson brothers concert two days later , she said . But she never arrived at the concert , Ribera said . When Paris Jackson called her aunts Rebbie and Janet over the past several days to find her grandmother , she was told each time she could not speak to her , Ribera said . In another tweet , Paris Jackson gave out her bodyguard 's phone number and asked people to call the authorities if they saw her grandmother . `` The kids were trying to get a hold of their grandmother and they have n'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 never gone 24 hours without talking to her kids , '' she said . `` I 'm concerned that she would never do this . 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 . Family , fans remember Michael Jackson . The sheriff 's homicide-missing persons unit has been asked to investigate , Ribera said . A letter was made public Wednesday in which two daughters , Rebbie and Janet , and three sons -- Jermaine , Randy and Tito -- charge that Katherine Jackson was being mistreated by the executors of Michael Jackson 's estate and mis-advised by her manager and lawyer .
