Jermaine Jackson released a statement earlier this week about his mother's whereabouts, saying this is all "a conspiracy to deflect attention away from a letter we wrote asking for the resignation of executors" of Michael Jackson's will.
Five of Michael Jackson's siblings last week said his will was fake and the executors of his lucrative estate, John McClain and John Blanca, should step down. Jackson's entire fortune was left to his mother and three kids.
"They [executors of the will] will not stand down because the siblings who were left out of Michael's will want them to," said Zia Modabber, who is the attorney for the Jackson estate.
Howard Mann, Katherine Jackson's business partner, believed money was pulling the family apart.
"I believe that Katherine and the children who are benefactors of the estate fall on one side, and then Randy, Jermaine and Rebbie and Tito fall on the other side," Mann said. "They're a group of people who have a great deal of questions about the administration of the estate."
Modabber said, "I can't speak for them. I don't know what's motivating Jermaine and Randy and some of these others, but money is not a bad guess."
Modabber and Mann faced off in court Monday in a dispute over Mann and Katherine Jackson's selling Michael Jackson merchandise.
"It doesn't matter that it's Howard Mann and he may give some of the money to his family, to Katherine Jackson or anybody else," Modabber said. "You can't take property that belongs to the estate, make money from it, without getting permission from the estate."
Mann's attorney argues the material is and always was owned by Katherine Jackson and her husband, Joe, and not the late King of Pop.
Michael Jackson's estate is worth about $1 billion and counting.
