Authorities believe that Katherine Jackson, the 82-year-old mother of Michael Jackson, is safe with family in Arizona after another family member filed a missing person report Saturday night, reports The Washington Post. Her granddaughter, Paris Jackson, had also expressed worry, tweeting, “Yes, my grandmother is missing. I haven’t spoken with her in a week I want her home now.”

This comes amid an extended familial squabble over control of Michael Jackson’s estate, and only days after it was revealed that some of Katherine’s children had written a letter to the estate’s executors claiming the pop superstar’s will had been falsified and that Katherine Jackson was in ill health. The family’s in-fighting and posturing has made headlines multiple times since Michael Jackson’s 2009 death.
