Katherine Jackson not missing: Michael's mom at Arizona treatment center

Michael Jackson's 82-year-old mother, Katherine Jackson, was reported missing late on Saturday (July 21), but she's since been located and is safe and sound at an Arizona hospital treatment center.

Here's what happened:

Late on Saturday, a nephew filed a missing persons report with the Los Angeles Sheriff's Department after he was allegedly unable to contact Jackson for more than a week, reports TMZ.

TMZ also reports that Jackson may have recently suffered a stroke. The family has been feuding about the executors of Michael's estate.

Global Grind reports that Katherine is in fact in treatment at an Arizona hospital, a claim made by Jermaine Jackson earlier in the week.

The Sheriff's department concurs, releasing this statment early Sunday morning:
"Katherine Jackson is reportedly with family members."
