On Saturday night, Katherine Jackson, mother of the late Michael Jackson, was reported missing by her nephew, Trent. According to CNN, Paris, the 14-year-old granddaughter who lives with her, had made several calls but was unable to reach her grandmother for a week. However on Thursday, Jermaine Jackson tweeted that his mother is "fine" and "resting up" in Arizona. Still, Katherine Jackson's lawyer said that the matriarch rarely goes 24 hours without speaking with her grandchildren. 

"This is our mother and her health is paramount. We are not inventing or plotting anything. We are following doctor's advice. Period," [Jermaine] added.

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.
